14-14: Consider adding a public getter for sequenceId

The sequenceId variable is now private. If external contracts or users need to access the current sequenceId, consider adding a public function to expose its value.

---

24-32: Introduce a PAUSER_ROLE for pausing functionality

Currently, the pause and unpause functions are restricted to DEFAULT_ADMIN_ROLE. It's good practice to define a dedicated PAUSER_ROLE. This allows you to grant pausing permissions without giving full administrative rights.

Apply this diff to implement PAUSER_ROLE:

+    bytes32 public constant PAUSER_ROLE = keccak256("PAUSER_ROLE");

    function initialize() public initializer {
        __UUPSUpgradeable_init();
        __AccessControl_init();
        __Pausable_init();
        _grantRole(DEFAULT_ADMIN_ROLE, msg.sender);
+       _grantRole(PAUSER_ROLE, msg.sender);
    }

    /// @notice Pauses the contract.
-   function pause() public onlyRole(DEFAULT_ADMIN_ROLE) {
+   function pause() public onlyRole(PAUSER_ROLE) {
        _pause();
    }

    /// @notice Unpauses the contract.
-   function unpause() public onlyRole(DEFAULT_ADMIN_ROLE) {
+   function unpause() public onlyRole(PAUSER_ROLE) {
        _unpause();
    }

---

48-50: Consider introducing an UPGRADER_ROLE for upgrade authorization

To allow more granular access control over contract upgrades, consider defining an UPGRADER_ROLE instead of using DEFAULT_ADMIN_ROLE. This way, you can assign upgrade permissions without granting full admin rights.

Apply this diff to implement UPGRADER_ROLE:

+    bytes32 public constant UPGRADER_ROLE = keccak256("UPGRADER_ROLE");

    function initialize() public initializer {
        __UUPSUpgradeable_init();
        __AccessControl_init();
        __Pausable_init();
        _grantRole(DEFAULT_ADMIN_ROLE, msg.sender);
+       _grantRole(UPGRADER_ROLE, msg.sender);
    }

    /// @dev Authorizes the upgrade of the contract.
    /// @param newImplementation The address of the new implementation.
-   function _authorizeUpgrade(address newImplementation) internal override onlyRole(DEFAULT_ADMIN_ROLE) {
+   function _authorizeUpgrade(address newImplementation) internal override onlyRole(UPGRADER_ROLE) {
        emit UpgradeAuthorized(msg.sender, newImplementation);
    }

14-14: Consider adding a public getter for sequenceId

The sequenceId variable is now private. If external access to sequenceId is required, consider adding a public function to expose its value.

10-11: Ensure secure handling of the private key

Retrieving the private key from the environment variable PRIVATE_KEY is acceptable. Ensure that this environment variable is securely managed and not exposed in version control systems or logs.

1-50: ⚠️ Potential issue

Apply the same security improvements as GroupMessages.sol

This contract has the same structure as GroupMessages.sol. Please apply the same improvements:

1. Add initializer modifier to sequenceId
2. Add storage gap for safe upgradeability
3. Add custom events for pause/unpause actions
4. Add size validation for identity updates

Additionally, consider adding validation for the inboxId parameter.

contracts/src/GroupMessages.sol (1)

24-32: Consider adding custom events for pause/unpause actions

While OpenZeppelin's Pausable contract emits events, consider adding custom events for better tracking of who performed these actions.

+    event GroupMessagesPaused(address admin);
+    event GroupMessagesUnpaused(address admin);

     function pause() public onlyRole(DEFAULT_ADMIN_ROLE) {
         _pause();

25-30: Add deployment verification logs

Consider adding more detailed logging to help verify the deployment success, including contract interfaces and roles setup.

         console.log(
-            '{"deployer":"%s","proxy":"%s","implementation":"%s"}',

contracts/script/upgrades/UpgradeGroupMessages.s.sol (2)

27-32: Enhance upgrade logging

Add more detailed logging to track upgrade status and versions.

         console.log(

-            upgrader,

+            currentImplementation,
+            address(newImplementation)
         );

---

1-36: Consider implementing version control mechanism

The upgrade script should implement version control to prevent downgrade attacks and ensure proper upgrade sequence.

Consider adding:

1. Version tracking in the implementation contract
2. Version checks in the upgrade script
3. Documentation of breaking changes between versions
4. Upgrade requirements validation

Would you like me to provide an example implementation of these features?

contracts/src/GroupMessages.sol (1)

31-39: Add events for pause/unpause actions

The pause and unpause functions should emit events for better transparency and monitoring.

+    event ContractPaused(address admin);
+    event ContractUnpaused(address admin);

     function pause() public onlyRole(DEFAULT_ADMIN_ROLE) {
         _pause();
+        emit ContractPaused(msg.sender);
     }

     function unpause() public onlyRole(DEFAULT_ADMIN_ROLE) {
         _unpause();
+        emit ContractUnpaused(msg.sender);
     }

contracts/src/IdentityUpdates.sol (1)

9-61: Consider extracting common functionality to a base contract

Both GroupMessages and IdentityUpdates share significant code. Consider creating a base contract to reduce duplication.

Create a new base contract like:

abstract contract XMTPUpgradeableBase is 
    Initializable, 
    AccessControlUpgradeable, 
    UUPSUpgradeable, 
    PausableUpgradeable 
{
    uint64 private sequenceId;
    uint256[50] private __gap;

    function __XMTPUpgradeableBase_init(address admin) internal onlyInitializing {
        require(admin != address(0), "Admin address cannot be zero");
        __UUPSUpgradeable_init();
        __AccessControl_init();
        __Pausable_init();
        _grantRole(DEFAULT_ADMIN_ROLE, admin);
    }

    function pause() public onlyRole(DEFAULT_ADMIN_ROLE) {
        _pause();
    }

    function unpause() public onlyRole(DEFAULT_ADMIN_ROLE) {
        _unpause();
    }

    function _authorizeUpgrade(address newImplementation) 
        internal 
        override 
        onlyRole(DEFAULT_ADMIN_ROLE) 
    {
        require(newImplementation != address(0), "New implementation cannot be zero address");
        emit UpgradeAuthorized(msg.sender, newImplementation);
    }
}

contracts/test/GroupMessage.t.sol (2)

24-31: Consider adding validation for proxy deployment.

While the setup is correct, consider adding assertions to verify:

1. The proxy deployment was successful
2. The initialization was successful
3. The admin role was properly set

 function setUp() public {
     groupMessagesImpl = new GroupMessages();

     proxy = new ERC1967Proxy(
         address(groupMessagesImpl), 
         abi.encodeWithSelector(GroupMessages.initialize.selector, admin)
     );

     groupMessages = GroupMessages(address(proxy));
+    // Verify setup
+    assertEq(groupMessages.hasRole(DEFAULT_ADMIN_ROLE, admin), true);
+    assertEq(address(proxy).code.length > 0, true);
 }

---

34-54: Consider adding edge case tests for message validation.

While basic valid/invalid cases are covered, consider adding tests for:

1. Empty messages
2. Messages at exact size boundaries
3. Messages with special characters or patterns

+    function testAddMessageEmpty() public {
+        bytes memory message = new bytes(0);
+        vm.expectRevert(GroupMessages.InvalidMessage.selector);
+        groupMessages.addMessage(GROUP_ID, message);
+    }
+
+    function testAddMessageExactSize() public {
+        bytes memory message = new bytes(1024);  // Max size
+        groupMessages.addMessage(GROUP_ID, message);
+        
+        message = new bytes(78);  // Min size
+        groupMessages.addMessage(GROUP_ID, message);
+    }

contracts/test/IdentityUpdates.t.sol (1)

1-134: Consider reducing code duplication between test contracts.

Both test contracts share significant amounts of similar code. Consider extracting common test patterns into a base test contract.

Example structure:

abstract contract UpgradeableTest is Test {
    bytes32 constant DEFAULT_ADMIN_ROLE = 0x00;
    bytes32 constant EIP1967_IMPL_SLOT = 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc;
    
    address admin;
    address unauthorized;
    
    function setUp() virtual public {
        admin = address(this);
        unauthorized = address(0x1);
    }
    
    // Common test functions for pause/unpause, roles, and upgrades
}

2-2: Consider using ^0.8.28 for pragma version

While pinning to an exact version ensures build reproducibility, using ^0.8.28 would allow for patch updates while maintaining compatibility. This is particularly useful for security fixes.

-pragma solidity 0.8.28;
+pragma solidity ^0.8.28;

---

6-9: Add NatSpec documentation and consider network-specific output files

While the implementation is correct, consider these improvements:

1. Add NatSpec documentation to explain the purpose and usage of these constants
2. Consider prefixing the output files with network information to avoid conflicts when deploying to different networks

+/// @title Environment
+/// @notice Deployment configuration constants for XMTP contracts
+/// @dev Used by deployment scripts to maintain consistent output file naming
 contract Environment is Script {
-    string public constant XMTP_GROUP_MESSAGES_OUTPUT_JSON = "group_messages_deployment";
-    string public constant XMTP_IDENTITY_UPDATES_OUTPUT_JSON = "identity_updates_deployment";
+    /// @notice Output file name for GroupMessages contract deployment
+    string public constant XMTP_GROUP_MESSAGES_OUTPUT_JSON = "{network}_group_messages_deployment";
+    /// @notice Output file name for IdentityUpdates contract deployment
+    string public constant XMTP_IDENTITY_UPDATES_OUTPUT_JSON = "{network}_identity_updates_deployment";
 }

contracts/script/upgrades/UpgradeIdentityUpdates.s.sol (1)

17-20: Add environment variable validation

Consider adding validation for the environment variables before using them to prevent deployment issues.

     function run() external {
         uint256 privateKey = vm.envUint("PRIVATE_KEY");
+        require(privateKey != 0, "PRIVATE_KEY environment variable not set");
         upgrader = vm.addr(privateKey);

contracts/src/IdentityUpdates.sol (1)

21-22: Document storage gap size calculation

     /// @dev Reserved storage gap for future upgrades
-    uint256[50] private __gap;
+    /// @dev Reserved storage gap for future upgrades.
+    /// Current storage usage: 1 slot (sequenceId)
+    /// Reserved slots: 50
+    /// Available slots for future upgrades: 49
+    uint256[50] private __gap;

contracts/test/IdentityUpdates.t.sol (2)

23-31: Add edge case tests for initialization

Consider adding test cases for:

• Initialization with zero address admin
• Initialization with empty implementation
• Proxy deployment with invalid initialization data

     function setUp() public {
         identityUpdatesImpl = new IdentityUpdates();
 
         proxy = new ERC1967Proxy(
             address(identityUpdatesImpl), 
             abi.encodeWithSelector(identityUpdates.initialize.selector, admin)
         );
 
         identityUpdates = IdentityUpdates(address(proxy));
+        
+        // Add helper function for testing invalid initialization
+        function testInvalidInitialization() public {
+            vm.expectRevert("Admin address cannot be zero");
+            new ERC1967Proxy(
+                address(identityUpdatesImpl),
+                abi.encodeWithSelector(identityUpdates.initialize.selector, address(0))
+            );
+        }
     }

---

95-134: Add upgrade failure scenario tests

Consider adding test cases for:

• Upgrade to zero address implementation
• Upgrade with invalid initialization data
• Upgrade during paused state

     function testUpgradeImplementation() public {
         // ... existing tests ...
+        
+        // Test upgrade to zero address
+        vm.expectRevert("New implementation cannot be zero address");
+        identityUpdates.upgradeToAndCall(address(0), "");
+        
+        // Test upgrade during paused state
+        identityUpdates.pause();
+        vm.expectRevert("Pausable: paused");
+        identityUpdates.upgradeToAndCall(address(newIdentityUpdatesImpl), "");
     }

contracts/script/DeployGroupMessages.s.sol (3)

2-2: Confirm the solidity version is pinned.
While pragma solidity 0.8.28 is reasonable, consider pinning the patch version (e.g., 0.8.28) to avoid unforeseen minor version updates.

---

20-21: Allow multi-sig or contract-based administrators if desired.
Currently, the code explicitly disallows an admin that is a contract by checking “admin.code.length == 0”. Some teams use a Gnosis Safe or other contract-based wallet as the admin to manage upgrade privileges. Consider relaxing this requirement if multi-sig administration is intended.

---

43-47: Clarify JSON serialization identifiers.
“parent_object” and “addresses” are somewhat generic. Using a clearer name might improve readability and reduce confusion if multiple deployment scripts produce JSON outputs.

Also applies to: 49-60

contracts/script/upgrades/UpgradeGroupMessages.s.sol (1)

29-30: Consider implementing upgrade rollback or verification logic.
The script upgrades the proxy with no fallback if the upgrade fails on-chain. For safety, you could implement an approach to restore the old implementation if the upgrade call reverts. This helps avoid issues if the new implementation is flawed.

contracts/src/GroupMessages.sol (2)

14-14: Rename error to match contract semantics.
Consider renaming “InvalidIdentityUpdateSize” to “InvalidMessageSize” for consistency with message-related operations.

---

46-49: Consider adding nonReentrant if storing large data.
While no external calls are made, adding a nonReentrant modifier (from OpenZeppelin) might provide an extra safety net, especially for a function that processes large payloads.

contracts/test/GroupMessage.t.sol (2)

46-54: Test boundary conditions for max payload size.
There’s a test for an undersized message. Similarly, consider adding a test for an oversized message (exceeding MAX_PAYLOAD_SIZE) to ensure that path is covered.

---

96-100: Extend upgrade testing with invalid implementation checks.
While the suite tests an unauthorized upgrade and reverts, consider also verifying that the new implementation’s code size is nonzero and adding a mock “broken” implementation to test advanced rollback scenarios.

Also applies to: 106-110, 116-120, 122-125

contracts/script/DeployIdentityUpdates.s.sol (1)

43-60: Improve serialization function robustness and efficiency

Consider the following improvements:

1. Use constants for static strings
2. Add validation for the output path
3. Add error handling for the write operation

-    function _serializeDeploymentData() internal {
-        string memory parent_object = "parent object";
-        string memory addresses = "addresses";
+    // Constants for serialization
+    string constant PARENT_OBJECT = "parent object";
+    string constant ADDRESSES = "addresses";
+
+    function _serializeDeploymentData() internal {
+        require(bytes(XMTP_IDENTITY_UPDATES_OUTPUT_JSON).length > 0, "Invalid output path");
+
         string memory addressesOutput;
-        addressesOutput = vm.serializeAddress(addresses, "identityUpdatesDeployer", deployer);
+        addressesOutput = vm.serializeAddress(ADDRESSES, "identityUpdatesDeployer", deployer);
         // ... rest of serialization ...
-        writeOutput(finalJson, XMTP_IDENTITY_UPDATES_OUTPUT_JSON);
+        try this.writeOutput(finalJson, XMTP_IDENTITY_UPDATES_OUTPUT_JSON) {
+            // Success
+        } catch Error(string memory reason) {
+            revert(string.concat("Failed to write deployment data: ", reason));
+        }
     }

contracts/script/utils/Utils.sol (2)

20-23: Refactor to reduce code duplication and add input validation.

The function duplicates file reading logic from readInput. Consider creating a shared internal function for file reading with proper validation.

+function readFile(string memory path, string memory filename) internal view returns (string memory) {
+    require(bytes(filename).length > 0, "Empty filename");
+    require(!contains(filename, ".."), "Invalid path sequence");
+    require(!contains(filename, "/"), "Invalid character in filename");
+    string memory fullPath = string.concat(path, filename, ".json");
+    return vm.readFile(fullPath);
+}

 function readInput(string memory inputFileName) internal view returns (string memory) {
-    string memory file = getInputPath(inputFileName);
-    return vm.readFile(file);
+    return readFile(getInputBasePath(), inputFileName);
 }

 function readOutput(string memory outputFileName) internal view returns (string memory) {
-    string memory file = getOutputPath(outputFileName);
-    return vm.readFile(file);
+    return readFile(getOutputBasePath(), outputFileName);
 }

---

7-36: Consider adding logging and access control.

For better operational visibility and security:

1. Add events for important file operations
2. Consider implementing access control to restrict who can call these functions
3. Add documentation for the contract's purpose and usage

Example implementation:

 contract Utils is Script {
+    event FileRead(string indexed fileName, uint256 chainId);
+    event FileWritten(string indexed fileName, uint256 chainId);
+
+    /// @notice Modifier to ensure the caller has appropriate permissions
+    modifier onlyAuthorized() {
+        require(msg.sender == address(this) || msg.sender == owner, "Unauthorized");
+        _;
+    }
+
     function readInput(string memory inputFileName) internal view returns (string memory) {
         string memory file = getInputPath(inputFileName);
-        return vm.readFile(file);
+        string memory content = vm.readFile(file);
+        emit FileRead(inputFileName, block.chainid);
+        return content;
     }

Add dependency checks between contract deployment and node registration

After analyzing the scripts, there are no explicit dependency checks between contract deployment and node registration. This could lead to race conditions where:

• Node registration might fail if attempted before contracts are fully deployed and initialized
• The Nodes contract address might not be available to the registration process

Suggested improvements:

• Add a check in the registration scripts to verify the Nodes contract is deployed and accessible
• Consider adding a small delay or retry mechanism in case of contract deployment latency
• Implement a check for the contract address in build/Nodes.json before proceeding with registration

The current implementation assumes perfect timing and doesn't handle potential edge cases in the deployment sequence.

🔗 Analysis chain

Line range hint 19-26: Verify the execution order dependencies

The sequence of operations (deploy contracts -> register nodes) implies a dependency. Let's verify if there are any timing or dependency checks in the called scripts.

dev/contracts/deploy-testnet (1)

28-29: Consider comprehensive deployment architecture improvements

The TODOs highlight important improvements needed for a robust deployment process:

1. Migration to forge script would provide:
   • Type safety
   • Better error handling
   • Structured deployment steps
   • Reusable deployment logic
2. Verification needs for both implementation and proxy contracts

Consider implementing a comprehensive deployment architecture:

1. Create separate forge scripts for each contract
2. Implement proper proxy initialization
3. Add post-deployment verification
4. Include deployment configuration management
5. Add deployment status logging
6. Consider adding deployment role checks

Would you like assistance in creating this improved deployment architecture?

dev/contracts/.env (1)

5-9: Consider separating admin roles for better security

Currently, all three admin addresses (XMTP_GROUP_MESSAGES_ADMIN_ADDRESS, XMTP_IDENTITY_UPDATES_ADMIN_ADDRESS, and XMTP_NODE_REGISTRY_ADMIN_ADDRESS) are set to the same value. While this might be convenient for development, it centralizes control and increases security risk.

Recommendations:

1. Consider using different admin addresses for each contract in production to implement separation of concerns
2. Add documentation about the specific permissions and responsibilities of each admin role
3. Consider implementing a multi-signature wallet pattern for critical admin operations

contracts/README.md (1)

15-15: Enhance the experimental warning with specific risks

While the experimental warning is good, it would be more helpful to explicitly mention potential risks such as contract upgrades, possible state changes, or security implications.

-**⚠️ Experimental:** This software is in early development. Expect frequent changes and unresolved issues.
+**⚠️ Experimental:** This software is in early development. Users should be aware of:
+- Frequent contract upgrades and potential state changes
+- Possible security vulnerabilities under audit
+- Breaking changes in contract interfaces
+- Unresolved issues and limitations

23-23: Consider standardizing Nodes contract deployment.

The TODO comment indicates inconsistency in deployment methods. Consider migrating the Nodes contract deployment to use the same forge script pattern as other contracts for consistency.

Would you like help creating a deployment script for the Nodes contract following the same pattern?

contracts/test/utils/Utils.sol (2)

8-9: Add documentation for constant values.

Consider adding NatSpec documentation explaining the purpose and significance of these constants, especially EIP1967_IMPL_SLOT which is critical for proxy implementations.

---

11-17: Consider optimizing payload generation.

The current implementation has potential issues:

1. No length validation could lead to out-of-gas errors with large inputs
2. The modulo operation in a loop is gas-intensive

Consider this optimization:

 function _generatePayload(uint256 length) public pure returns (bytes memory) {
+    require(length <= 10000, "Payload too large");
     bytes memory payload = new bytes(length);
     for (uint256 i = 0; i < payload.length; i++) {
-        payload[i] = bytes1(uint8(i % 256));
+        payload[i] = bytes1(uint8(i & 0xFF));  // More gas efficient than modulo
     }
     return payload;
 }

dev/contracts/common (1)

7-7: Reconsider suppressing deployment output.

The &> /dev/null redirection might hide important deployment information or warnings. Consider logging to a file instead of completely suppressing output.

-    forge script --rpc-url "${DOCKER_RPC_URL}" --broadcast script/DeployGroupMessages.s.sol &> /dev/null
+    forge script --rpc-url "${DOCKER_RPC_URL}" --broadcast script/DeployGroupMessages.s.sol > deployment.log 2>&1

Also applies to: 19-19

contracts/test/GroupMessage.t.sol (2)

154-193: Enhance upgrade implementation tests.

While the upgrade process is well-tested, consider adding:

1. Test for failed upgrades recovery
2. Verification of function selectors in the new implementation
3. Test upgrade with non-empty calldata

     function testUpgradeImplementation() public {
         // ... existing tests ...
+        
+        // Test upgrade with non-empty calldata
+        bytes memory initData = abi.encodeWithSelector(GroupMessages.someFunction.selector);
+        groupMessages.upgradeToAndCall(address(newGroupMessagesImpl), initData);
+        
+        // Verify function selectors
+        bytes4 selector = groupMessages.addMessage.selector;
+        assertTrue(newGroupMessagesImpl.supportsInterface(selector));
     }

---

73-81: Add more comprehensive pause state tests.

Consider adding tests for:

1. Events emitted during pause/unpause
2. Multiple pause/unpause transitions
3. State preservation across pause/unpause

     function testAddMessageWhenPaused() public {
         bytes memory message = _generatePayload(MIN_PAYLOAD_SIZE);
 
         groupMessages.pause();
         assertTrue(groupMessages.paused());
 
+        // Test events
+        vm.expectEmit(address(groupMessages));
+        emit Paused(address(this));
+        
         vm.expectRevert(abi.encodeWithSelector(PausableUpgradeable.EnforcedPause.selector));
         groupMessages.addMessage(ID, message);
+        
+        // Test multiple transitions
+        groupMessages.unpause();
+        groupMessages.pause();
+        groupMessages.unpause();
+        assertFalse(groupMessages.paused());
     }

contracts/test/IdentityUpdates.t.sol (4)

14-29: Consider adding validation in setUp.

While the setup follows the correct pattern for upgradeable contracts, consider adding these validations:

 function setUp() public {
     identityUpdatesImpl = new IdentityUpdates();
+    require(address(identityUpdatesImpl) != address(0), "Implementation deployment failed");
 
     proxy = new ERC1967Proxy(
         address(identityUpdatesImpl),
         abi.encodeWithSelector(identityUpdates.initialize.selector, admin)
     );
+    require(address(proxy) != address(0), "Proxy deployment failed");
 
     identityUpdates = IdentityUpdates(address(proxy));
+    require(identityUpdates.hasRole(DEFAULT_ADMIN_ROLE, admin), "Admin role not set");
 }

---

73-81: Consider extending pause test coverage.

While the test verifies paused state behavior, consider adding verification for successful updates after unpausing.

 function testAddIdentityUpdateWhenPaused() public {
     bytes memory message = _generatePayload(MIN_PAYLOAD_SIZE);
 
     identityUpdates.pause();
     assertTrue(identityUpdates.paused());
 
     vm.expectRevert(abi.encodeWithSelector(PausableUpgradeable.EnforcedPause.selector));
     identityUpdates.addIdentityUpdate(ID, message);
+    
+    identityUpdates.unpause();
+    assertFalse(identityUpdates.paused());
+    
+    vm.expectEmit(address(identityUpdates));
+    emit IdentityUpdates.IdentityUpdateCreated(ID, message, 1);
+    identityUpdates.addIdentityUpdate(ID, message);
 }

---

84-98: Consider adding state verification.

While the test verifies events, consider adding direct state verification of the sequence ID.

 function testSequenceIdIncrement() public {
     bytes memory message = _generatePayload(MIN_PAYLOAD_SIZE);
 
     vm.expectEmit(address(identityUpdates));
     emit IdentityUpdates.IdentityUpdateCreated(ID, message, 1);
     identityUpdates.addIdentityUpdate(ID, message);
+    assertEq(identityUpdates.getCurrentSequenceId(), 1);
 
     vm.expectEmit(address(identityUpdates));
     emit IdentityUpdates.IdentityUpdateCreated(ID, message, 2);
     identityUpdates.addIdentityUpdate(ID, message);
+    assertEq(identityUpdates.getCurrentSequenceId(), 2);
 
     vm.expectEmit(address(identityUpdates));
     emit IdentityUpdates.IdentityUpdateCreated(ID, message, 3);
     identityUpdates.addIdentityUpdate(ID, message);
+    assertEq(identityUpdates.getCurrentSequenceId(), 3);
 }

---

154-193: Consider verifying additional state after upgrade.

While the test verifies sequence ID preservation and implementation address, consider verifying other important state variables:

 function testUpgradeImplementation() public {
     // ... existing setup code ...
 
     identityUpdates.upgradeToAndCall(address(newIdentityUpdatesImpl), "");
 
     // ... implementation address verification ...
 
+    // Verify other important state
+    assertTrue(identityUpdates.hasRole(DEFAULT_ADMIN_ROLE, admin));
+    assertFalse(identityUpdates.paused());
+    
     // Next sequenceId should be 2
     vm.expectEmit(address(identityUpdates));
     emit IdentityUpdates.IdentityUpdateCreated(ID, message, 2);
     identityUpdates.addIdentityUpdate(ID, message);
 }

contracts/script/DeployGroupMessages.s.sol (3)

11-14: Leverage additional comments clarifying script usage.
This contract's purpose is clear, but consider adding a descriptive natspec or comment for the script’s workflow. For instance, explaining that it deploys the implementation and proxy for GroupMessages.

---

18-26: Add optional pre-deployment checks for private key and broadcast readiness.
Currently, the script directly uses the private key from environment variables. Consider verifying that the environment variable meets your validation criteria (before calling vm.startBroadcast), such as confirming it’s a valid 32-byte hex string.

 function run() external {
     admin = vm.envAddress("XMTP_GROUP_MESSAGES_ADMIN_ADDRESS");
     require(admin != address(0), "XMTP_GROUP_MESSAGES_ADMIN_ADDRESS not set");
     require(admin.code.length == 0, "admin address is a contract, not an EOA");

+    // Optional pre-deployment check for PRIVATE_KEY format
+    string memory keyString = vm.envString("PRIVATE_KEY");
+    require(bytes(keyString).length == 64, "PRIVATE_KEY likely invalid format");

     uint256 privateKey = vm.envUint("PRIVATE_KEY");
     deployer = vm.addr(privateKey);
     vm.startBroadcast(privateKey);

---

38-39: Enhance clarity in _serializeDeploymentData with structured naming.
Your JSON keys like "parent_object" and "addresses" are placeholders. Consider using more descriptive identifiers (e.g., "deployInfo", "groupMessagesInfo") to improve clarity for external tooling or debugging.

 function _serializeDeploymentData() internal {
-    string memory parent_object = "parent object";
-    string memory addresses = "addresses";
+    string memory parent_object = "deployInfo";
+    string memory addresses = "groupMessagesInfo";
     
     ...
 }

contracts/script/upgrades/UpgradeIdentityUpdates.s.sol (1)

1-3: Check alignment with broader codebase version usage.
Similar to “DeployGroupMessages.s.sol,” validate that your chosen Solidity version is consistent across your upgrade scripts, deployment scripts, and contract code.

contracts/src/IdentityUpdates.sol (2)

9-10: Add a natspec description for contract purpose.
While the file has a basic heading, consider expanding the natspec summary to clarify how identity updates integrate with your overall system.

---

22-24: Refine error messages for better user feedback.
“ZeroAdminAddress()” and “InvalidPayloadSize(...)” are clear but you could add a short custom error message as an alternative to the require() revert reason, for improved debugging in certain dev tooling.

contracts/src/GroupMessages.sol (4)

17-20: Ensure standardization of event naming across modules.
You introduced “UpgradeAuthorized” here and in IdentityUpdates. Confirm the naming or consider a single cross-contract event naming convention (e.g., “UpgradeAuthorized” or “ContractUpgraded”).

---

22-24: Consider centralizing custom errors.
If multiple contracts define ZeroAdminAddress or InvalidPayloadSize, centralizing them in a shared library or interface helps keep code DRY and consistent across the codebase.

---

32-33: Sequence ID usage.
As with IdentityUpdates, confirm if an external getter is needed. Relying solely on internal or private usage might be fine if no on-chain reading by external actors is required.

---

41-49: Confirm admin role assignment in initialize.
A zero address check is done in line 42 using require, referencing the custom error ZeroAdminAddress(). This is slightly inconsistent. You could unify by doing if (_admin == address(0)) revert ZeroAdminAddress();.

- require(_admin != address(0), ZeroAdminAddress());
+ if (_admin == address(0)) {
+     revert ZeroAdminAddress();
+ }

contracts/test/GroupMessage.t.sol (2)

13-13: Consider separating test contract from implementation

Inheriting from GroupMessages in the test contract (is Test, GroupMessages, Utils) could lead to naming conflicts and make it unclear whether you're testing the implementation or the inherited functionality. Consider removing the inheritance and accessing GroupMessages only through the proxy instance.

---

73-81: Enhance pause functionality test coverage

The test verifies basic pause functionality, but consider adding:

1. Test message operations after unpause
2. Test multiple pause/unpause cycles
3. Verify events emitted during pause/unpause

 function testAddMessageWhenPaused() public {
     bytes memory message = _generatePayload(MIN_PAYLOAD_SIZE);
 
     groupMessages.pause();
     assertTrue(groupMessages.paused());
 
     vm.expectRevert(abi.encodeWithSelector(PausableUpgradeable.EnforcedPause.selector));
     groupMessages.addMessage(ID, message);
+    
+    groupMessages.unpause();
+    assertFalse(groupMessages.paused());
+    
+    // Verify operations work after unpause
+    vm.expectEmit(address(groupMessages));
+    emit GroupMessages.MessageSent(ID, message, 1);
+    groupMessages.addMessage(ID, message);
 }

contracts/test/IdentityUpdates.t.sol (1)

31-38: Maintain consistent test naming patterns across contracts

While the implementation is correct, consider maintaining consistent test naming patterns between GroupMessage.t.sol and IdentityUpdates.t.sol. For example:

• testAddIdentityUpdateValid vs testAddMessageValid
• testAddIdentityUpdateWithMaxPayload vs testAddMessageWithMaxPayload

This consistency makes it easier to understand and maintain the test suite.

32-33: Consider updating documentation for the new contract structure

The changes introduce a new contract artifact structure with proxy contracts. This architectural change should be documented.

Line range hint 45-63: Consider adding boundary test cases for payload size limits

While the test suite covers empty updates and a valid size, it would be beneficial to add test cases that verify behavior at the minimum and maximum payload size boundaries.

Consider adding these test cases to the existing suite:

 tests := []struct {
     name           string
     inboxId        [32]byte
     identityUpdate []byte
     ctx            context.Context
     wantErr        bool
 }{
     {
         name:           "happy path",
         inboxId:        testutils.RandomGroupID(),
         identityUpdate: testutils.RandomBytes(104),
         ctx:            context.Background(),
         wantErr:        false,
     },
+    {
+        name:           "minimum payload size",
+        inboxId:        testutils.RandomGroupID(),
+        identityUpdate: testutils.RandomBytes(MIN_PAYLOAD_SIZE),
+        ctx:            context.Background(),
+        wantErr:        false,
+    },
+    {
+        name:           "maximum payload size",
+        inboxId:        testutils.RandomGroupID(),
+        identityUpdate: testutils.RandomBytes(MAX_PAYLOAD_SIZE),
+        ctx:            context.Background(),
+        wantErr:        false,
+    },
+    {
+        name:           "exceeds maximum size",
+        inboxId:        testutils.RandomGroupID(),
+        identityUpdate: testutils.RandomBytes(MAX_PAYLOAD_SIZE + 1),

The TODO comment should include when getDeployedTo will be deprecated and what developers should use instead.

5-7: Consider making the script more flexible and robust

The new ANVIL_SCRIPTS_OUTPUT variable has a few potential improvements:

1. It should be exported since other exported variables depend on it
2. The network ID (31337) should be configurable to support different test networks
3. The script should validate that the output directory exists

Consider this improvement:

-# Anvil scripts output folder
-ANVIL_SCRIPTS_OUTPUT=contracts/script/output/31337
+# Anvil scripts output folder (default to local network 31337)
+NETWORK_ID=${NETWORK_ID:-31337}
+export ANVIL_SCRIPTS_OUTPUT="contracts/script/output/${NETWORK_ID}"
+
+# Validate output directory exists
+if [ ! -d "$ANVIL_SCRIPTS_OUTPUT" ]; then
+    echo "Error: Directory $ANVIL_SCRIPTS_OUTPUT does not exist"
+    exit 1
+fi

Line range hint 21-24: Security reminder regarding private keys

While these appear to be test private keys for Anvil accounts, as a best practice:

1. Ensure this file is in .gitignore
2. Consider moving sensitive values to a separate secrets file
3. Document that these are test-only keys

Consider adding a warning comment:

+# WARNING: These are test-only keys for local development.
+# Never use these keys in production or expose real private keys in environment files.
 export ANVIL_ACC_1_PRIVATE_KEY="0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d"

21-29: Enhance setUp with initialization validation

Consider adding assertions to verify the successful initialization of the proxy:

 function setUp() public {
     groupMessagesImpl = new GroupMessages();

     proxy = new ERC1967Proxy(
         address(groupMessagesImpl), abi.encodeWithSelector(GroupMessages.initialize.selector, admin)
     );

     groupMessages = GroupMessages(address(proxy));
+    
+    // Verify initialization
+    assertTrue(groupMessages.hasRole(groupMessages.DEFAULT_ADMIN_ROLE(), admin));
+    assertFalse(groupMessages.paused());
 }

---

40-71: Consider adding tests for duplicate message scenarios

The tests cover payload size constraints well, but consider adding tests for:

1. Duplicate message detection (if implemented)
2. Message uniqueness across different group IDs

+    function testDuplicateMessage() public {
+        bytes memory message = _generatePayload(MIN_PAYLOAD_SIZE);
+        
+        groupMessages.addMessage(ID, message);
+        
+        // Verify same message can be added to different group
+        bytes32 differentId = bytes32(uint256(ID) + 1);
+        groupMessages.addMessage(differentId, message);

129-152: Enhance role management test coverage

+        address operator = address(0x3);
+        
+        // Grant admin role
+        groupMessages.grantRole(DEFAULT_ADMIN_ROLE, newAdmin);
+        
+        // New admin should be able to grant roles
+        vm.prank(newAdmin);
+        groupMessages.grantRole(DEFAULT_ADMIN_ROLE, operator);
+        
+        // Verify original admin can still manage roles
+        groupMessages.revokeRole(DEFAULT_ADMIN_ROLE, operator);
+    }

73-81: Add event verification for pause operation

While the test verifies the revert behavior, it should also verify the emission of the Paused event from PausableUpgradeable.

+    vm.expectEmit(address(identityUpdates));
+    emit PausableUpgradeable.Paused(admin);
     identityUpdates.pause();
     assertTrue(identityUpdates.paused());
 
     vm.expectRevert(abi.encodeWithSelector(PausableUpgradeable.EnforcedPause.selector));
 
     identityUpdates.addIdentityUpdate(ID, message);
 }

---

84-98: Consider using a loop for sequence ID testing

The test could be more maintainable and concise by using a loop to verify multiple sequence IDs.

 function testSequenceIdIncrement() public {
     bytes memory message = _generatePayload(MIN_PAYLOAD_SIZE);
 
-    vm.expectEmit(address(identityUpdates));
-    emit IdentityUpdates.IdentityUpdateCreated(ID, message, 1);
-    identityUpdates.addIdentityUpdate(ID, message);
-
-    vm.expectEmit(address(identityUpdates));
-    emit IdentityUpdates.IdentityUpdateCreated(ID, message, 2);
-    identityUpdates.addIdentityUpdate(ID, message);
-
-    vm.expectEmit(address(identityUpdates));
-    emit IdentityUpdates.IdentityUpdateCreated(ID, message, 3);
-    identityUpdates.addIdentityUpdate(ID, message);
+    for (uint256 i = 1; i <= 3; i++) {
+        vm.expectEmit(address(identityUpdates));
+        emit IdentityUpdates.IdentityUpdateCreated(ID, message, i);
+        identityUpdates.addIdentityUpdate(ID, message);
+    }
 }

21-23: 🛠️ Refactor suggestion

Add information about contract upgradeability

The Messages Contracts section should mention the upgradeability pattern used.

 The messages contracts manage the blockchain state for `GroupMessages` and `IdentityUpdates` sent by clients to the network.

-These contracts ensure transparency and provide a historical record of state changes.
+These contracts ensure transparency and provide a historical record of state changes. They implement the UUPS (Universal Upgradeable Proxy Standard) pattern, allowing for future upgrades while maintaining state persistence.

---

75-102: 🛠️ Refactor suggestion

Enhance scripts documentation with upgrade process and validation

The scripts section needs more comprehensive documentation.

Add upgrade process and validation steps:

 The project includes deployer and upgrade scripts.

 ### Messages contracts
+
+#### Deployment Process
 
 - Configure the environment by providing an `.env` file, with this content:

 ```shell
 ### Main configuration
 PRIVATE_KEY=0xYourPrivateKey # Private key of the EOA deploying the contracts

 ### XMTP deployment configuration
 XMTP_GROUP_MESSAGES_ADMIN_ADDRESS=0x12345abcdf # the EOA assuming the admin role in the GroupMessages contract.
 XMTP_IDENTITY_UPDATES_ADMIN_ADDRESS=0x12345abcdf # the EOA assuming the admin role in the IdentityUpdates contract.

• Run the desired script with:

forge script --rpc-url <RPC_URL> --broadcast <PATH_TO_SCRIPT>

Example:

forge script --rpc-url http://localhost:7545 --broadcast script/DeployGroupMessages.s.sol

The scripts output the deployment and upgrade in the output folder.
+
+#### Upgrade Process
+
+To upgrade an existing contract:
+
+1. Deploy the new implementation:
+shell +forge script --rpc-url <RPC_URL> --broadcast script/UpgradeGroupMessages.s.sol +
+
+2. Verify the upgrade:
+shell +forge script --rpc-url <RPC_URL> script/ValidateGroupMessages.s.sol +
+
+#### Validation Steps
+
+After deployment or upgrade:
+1. Verify contract initialization
+2. Check admin roles are correctly set
+3. Validate proxy implementation address
+
+#### Troubleshooting
+
+Common issues and solutions:
+- Implementation contract verification fails
+- Proxy initialization reverts
+- Admin role transfer issues
