Add a New Chain

Want to bring your chain into the Brotocol ecosystem?
Whether you're an L1, L2, or appchain team, integrating with Brotocol opens your users to native Bitcoin liquidity, cross-chain swaps, and secure bridging—all while preserving Bitcoin as the settlement layer.
Here’s how to get started:
To support a new chain, Brotocol deploys a smart contract called an Endpoint, which acts as the entry and exit point for cross-chain asset transfers. These Endpoints are governed by multisigs (e.g. Gnosis Safe, ExecutorDAO) and coordinated through the Bonbori consensus layer.
Once deployed, your Endpoint becomes part of the BroBridge routing network—supporting swaps, payments, and bridging for supported assets.
To be eligible for integration, your chain should support:
✅ Smart contract deployment (EVM-compatible or custom logic)
✅ Reliable block finality for message validation
✅ Token standards (ERC-20 or equivalent) for fungible assets
✅ A relayer-friendly RPC interface for transaction submissions
For Bitcoin L2s or non-EVM chains, custom integration paths are available. Reach out to the team for support.
Reach out via Discord or email to start the process. Provide basic info:
Chain name & website
RPC endpoints & explorers
Token assets you want to support
Dev contact for coordination
Brotocol will deploy an Endpoint contract to your chain. This contract:
Receives incoming assets
Validates cryptographic proofs from Bonbori validators
Releases assets to users or contracts
Endpoints are owned by a multisig for security and flexibility.
Once deployed, the following parameters are set:
Approved token list
Validator set & thresholds
Fee structure
Supported swap paths (optional)
Brotocol relayers will monitor your chain’s Endpoint and submit proofs to/from other chains.
If your chain doesn’t natively support a desired asset (e.g., BTC), a synthetic version (e.g., aBTC or aUSD) may be deployed and mapped to real assets via BroBridge.
