This guide walks through deploying a sender contract on Sepolia (Ethereum testnet) and a receiver contract on Amoy (Polygon testnet), then sending and verifying arbitrary data across the bridge. For background on how state sync works, see the state sync architecture docs.
The contracts and scripts in this guide are simplified illustrations. Do not deploy them to production without a thorough security review and audit appropriate for your use case.
