+
+Hyperlane is a permissionless interoperability protocol that facilitates easy communication and asset transfers between blockchain networks. 
+It eliminates the need for centralized permissions, which enables developers to create and scale cross-chain applications effortlessly.
+
+## Why Use Hyperlane?
+Hyperlane makes cross-chain communication simple and accessible for developers. 
+
+Why it stands out:
+1. **No Permissions Needed:** Anyone can use Hyperlane on any blockchain—layer 1, rollup, or app-chain—without asking for approval.
+2. **No Middlemen:** It removes the need for centralized services, giving developers full control over their applications.
+3. **Easy Multi-Chain Setup:** Developers can quickly create apps that work across different blockchains.
+4. **Customizable Security:** With Interchain Security Modules (ISMs), developers can adjust the security settings to fit their app's needs.
+5. **Scalable and Flexible:** Hyperlane's design helps apps grow without bottlenecks or restrictions.
+
+
+## Get Started with Hyperlane
+Leverage pre-built components to kickstart your cross-chain development:
+
+1. **Warp Routes:** Enable seamless movement of native and ERC20 tokens across chains.
+2. **Interchain Accounts:** Allow accounts on one chain (e.g., a DAO) to execute smart contract calls on remote chains.
+3. **Interchain Queries:** Facilitate view calls from one chain to retrieve data from remote chains.

+---
+
+The PowPeg App, formerly the 2 Way Peg App, allows users to convert BTC to RBTC and vice versa. It is secured by the PowPeg protocol, a unique system that safeguards locked bitcoins using the same Bitcoin hash rate that establishes consensus.
+
+
+## Transaction Types
+
+- **Peg-in**: Convert BTC into RBTC by locking Bitcoin in a secure multi-signature wallet. After confirmation, an equivalent amount of RBTC is issued on the Rootstock blockchain.
+- **Peg-out**: Exchange RBTC back into BTC by burning RBTC on Rootstock and unlocking the corresponding BTC for transfer.
+
+## Why Use the PowPeg App?
+
+The PowPeg protocol is a robust mechanism for ensuring interoperability between Bitcoin and Rootstock. It offers:
+- **Security**: Bitcoin's hash rate guarantees asset safety during conversions.
+- **Decentralization**: Transactions rely on federated signing, minimizing risks of centralized control.
+- **Flexibility**: Enables access to Rootstock’s smart contract capabilities without leaving the Bitcoin ecosystem.

+tags: [cross chain, bridges, developer tools, rsk, testnet, rootstock, ethereum, dApps, smart contracts]

+
+Router Protocol enables developers to seamlessly interact with multiple blockchain networks, facilitating cross-chain transactions and decentralized finance (DeFi) solutions. To begin working with Router Protocol, you’ll need to understand some basic concepts and set up your development environment.
+
+## Key Concepts  
+
+This section introduces the foundational elements and architecture of the **Crosstalk Framework**, providing insights into its structure and critical features.  
+
+### **1. High-Level Architecture**  
+The **Crosstalk Framework** enables easy cross-chain communication and interoperability across multiple blockchain networks. Its architecture consists of the following core components:  
+- **Message Relayers**: Facilitate secure data and transaction transfers between different blockchain ecosystems.  
+- **Smart Contracts**: Handle cross-chain logic, including state synchronization and the execution of NFT transfers.  
+- **Router Infrastructure**: Serves as the central hub for communication, transaction routing, and data relaying across networks.  
+
+### **2. Fee Management**  
+Effective fee management is a critical feature of the Crosstalk Framework, ensuring transparent and efficient handling of transaction costs:  
+- **Fee Payer Account**: Each dApp integrates a designated fee payer account on the Router Chain to handle fees for cross-chain requests. This account, configurable per chain, can be updated at any time to adapt to changes.  
+- **Gas Considerations**:  
+  - Developers must provide **gasPrice** and **gasLimit** in the metadata of their CrossTalk requests to ensure successful execution on the destination chain.  
+  - If **gasPrice** is omitted, the Router Chain's gas price oracle automatically estimates it.  
+- **Prepaid Fee Model**:  
+  - Fees are calculated upfront in ROUTE tokens when a CrossTalk request is initiated.  
+  - This ensures the transaction on the destination chain has adequate funds for successful execution.  
+
+
+### **3. Additional Security Modules (ASM)**  
+To ensure robust security, the Crosstalk Framework incorporates Additional Security Modules (ASM), offering:  
+- **Fraud Detection**: Proactively detects and mitigates suspicious activities to protect the integrity of cross-chain interactions.  
+- **Fail-Safe Mechanisms**: Automatically pauses or cancels operations when potential security threats are identified, safeguarding user transactions.  
+
+
+## Build your first iDapp
+Creating your first interoperable decentralized application (iDapp) with Router Protocol is a straightforward two-step process:
+
+- [Create Your Cross-Chain NFT Contract](https://docs.routerprotocol.com/develop/message-transfer-via-crosstalk/evm-guides/your-first-crosschain-nft-contract/creating-your-nft-contract/)
+- [Deploy and Test Your NFT Contract](https://docs.routerprotocol.com/develop/message-transfer-via-crosstalk/evm-guides/your-first-crosschain-nft-contract/deploying-your-nft-contract/)
