Cross-Chain Messaging

RibbleChain's cross-chain messaging enables seamless communication between Layer 3 (L3) rollups and other blockchains (e.g., Ethereum, BNB Chain) using protocols like LayerZero and IBC. This API allows developers to send messages, transfer assets, and trigger actions across chains.

Overview

Cross-chain messaging is integral for multi-chain dApps, enabling use cases like cross-chain DeFi swaps, NFT bridging, and GameFi interoperability. The Cross-Chain API provides endpoints for:

• Sending cross-chain messages or assets.
• Querying message status and delivery.
• Configuring bridge parameters.

Prerequisites

• A deployed L3 rollup (see Getting Started with L3 Rollups).
• RibbleChain CLI: npm install -g ribblechain-cli.
• A smart wallet with $XRB tokens.

Step 1: Set Up Cross-Chain Bridge

Initialize the bridge for your rollup:

ribblechain-cli bridge init --rollup my-rollup --protocol layerzero
