Building using Rayls SDK

The Rayls SDK supports the development of decentralised applications (dApps) that interact with the Rayls protocol, the cross-chain protocol underneath the Rayls ecosystem. Developers use it to integrate cross-chain communication, which is what allows data and assets to move securely and efficiently between different blockchains.

Key Features

• Cross-Chain Message Sending: Send and receive messages between different chains using simplified functions that hold the complexity of cross-chain communication behind them.
• Endpoint Management: Configure and manage endpoints so that decentralised applications communicate reliably with the blockchains they need to reach.
• Resource Registration: Associate resource IDs with contract addresses, which preserves the integrity and traceability of transferred assets and data.
• Transfer Metadata: Use detailed metadata to track and manage asset transfers between chains, which gives visibility and control over cross-chain operations.

Advantages

• Simplified Integration: Clear interfaces and full documentation let developers integrate cross-chain functionality quickly.
• Security: The SDK is built on established security practice, so that cross-chain communications are protected against interference and malicious attack.
• Flexibility and Scalability: Designed to support a wide range of use cases and to scale as a project grows.

How to Use

1. Installation: Import the Rayls SDK into your Solidity development project.
2. Configuration: Initialise the SDK with the Rayls endpoint address you intend to use and configure the necessary parameters.
3. Implementation: Use the functions provided by the SDK to send messages, register resources, and manage endpoints, which is what carries communication between different blockchains.

Usage Examples

• Token Transfer: Transfer tokens securely between different chains.
• Contract Registration: Register contracts and associate resource IDs so that assets can be tracked and managed.
• Transfer Monitoring: Use transfer metadata to track the status and history of cross-chain operations.

The pages that follow cover installation and then each handler contract in turn, starting with the base RaylsApp contract that every other handler extends.
