|
||
| Foundry is a blazing fast, portable,modular toolkit for Ethereum application development written in Rust. | ||
|
|
||
| ## Introduction | ||
|
|
||
| This page details several parameters required to configure Foundry. The Foundry framework isn't described here; find that in the [Foundry documentation](https://book.getfoundry.sh). | ||
|
|
||
| ## Prerequisites | ||
| - cURL | ||
|
|
||
| ## Foundry configuration | ||
|
|
||
| Unlike other toolkits, Foundry doesn't have a config file to hold the chain parameters, instead, parameters are passed into commands. For example, this comand deploys a smart contract: | ||
|
|
||
| ``` | ||
| forge create --rpc-url $RPC_URL_DEVNET \ | ||
| --private-key $PRIVATE_KEY \ | ||
| --constructor-args "Test ERC20 Token" "TERC20" --legacy \ | ||
| src/TestERC20/TestERC20.sol:TestERC20 | ||
| ``` | ||
|
|
||
| The parameters for `forge create` command include: | ||
| * `--rpc-url`: RPC URL | ||
| * `--private-key`: The private key of the transaction signer | ||
| * `--constructor-args`: The constructor arguments to be passed to the contract that is being deployed | ||
| * `--legacy`: This parameter is being passed to use legacy transactions _(Neon EVM currently [doesn't support EIP-1559 transactions](/docs/evm_compatibility/overview#shared-standards-and-features))_ | ||

|
||
| ## Introduction | ||
|
|
||
| <WhatHardHat/> | ||
|
|
||
| The Hardhat framework isn't described here; find that in the [Hardhat documentation](https://hardhat.org/getting-started/#overview). | ||
|
|
||
| ## Prerequisites | ||
| - `NodeJS` | ||
|
|
||
| ## The Hardhat Configuration File | ||
|
|
||
| <ConfigHardHat/> | ||
|
|
||
| We provide a full example of the `hardhat.config.js` configuration file for connecting Hardhat to a Devnet Proxy using the one-way library on Node.js: | ||
|
|
||
| ### hardhat.config.js | ||
|
|
||
| ```js | ||
| require("@nomicfoundation/hardhat-toolbox"); | ||
| require("dotenv").config(); | ||
|
|
||
| /** @type import('hardhat/config').HardhatUserConfig */ | ||
| module.exports = { | ||
| solidity: "0.8.21", | ||
| defaultNetwork: "neondevnet", | ||
| etherscan: { | ||
| apiKey: { | ||
| neonevm: "test" | ||
| }, | ||
| customChains: [ | ||
| { | ||
| network: "neonevm", | ||
| chainId: 245022926, | ||
| urls: { | ||
| apiURL: "https://devnet-api.neonscan.org/hardhat/verify", | ||
| browserURL: "https://devnet.neonscan.org" | ||
| } | ||
| }, | ||
| { | ||
| network: "neonevm", | ||
| chainId: 245022934, | ||
| urls: { | ||
| apiURL: "https://api.neonscan.org/hardhat/verify", | ||
| browserURL: "https://neonscan.org" | ||
| } | ||
| } | ||
| ] | ||
| }, | ||
| networks: { | ||
| neondevnet: { | ||
| url: "https://devnet.neonevm.org", | ||
| accounts: [process.env.PRIVATE_KEY_OWNER], | ||
| chainId: 245022926 | ||
| }, | ||
| neonmainnet: { | ||
| url: "https://neon-proxy-mainnet.solana.p2p.org", | ||
| accounts: [process.env.PRIVATE_KEY_OWNER], | ||
| chainId: 245022934 | ||
| } | ||
| } | ||
| }; | ||
| ``` | ||
|
|
||
| The parameters for `module.exports` include: | ||
| * `solidity`: version of Solidity used | ||
| * `defaultNetwork`: default chain (for deploying or testing) | ||
| * `etherscan`: settings used to verify contracts on-chain [read more here](https://hardhat.org/hardhat-runner/docs/guides/verifying) | ||
| * `networks`: the list of the supported networks | ||
| * `neondevnet`: | ||
| * `url`: RPC URL | ||
| * `accounts`: an array of deployer's private keys; in the current example, PRIVATE_KEY_OWNER is stored inside .env file | ||
| * `chainId`: the network's chain ID | ||
|
|
||
| Note that `url` and `chainId` can be retrieved from the RPC endpoints table and/or [Chainlist](https://chainlist.org/?search=Neon+EVM&testnets=true). | ||
|
|
||
| ## What next? | ||
|
|
||
| See the [tutorial on how to use Hardhat to deploy to Neon EVM](/docs/developing/deploy_facilities/using_hardhat). | ||
|
|
||
| ## Gotchas | ||
|
|
||
| :::info | ||
| Remember, the deployer wallet address needs to have enough tokens to cover the gas cost of a deployment. | ||
