Project
Arc Relay Bridge is an open-source, mainnet-only interface for moving native USDC between Arc Mainnet and Base Mainnet with Circle CCTP V2.
Repository: https://github.com/osr21/arc-relay-bridge
Mainnet validation: https://github.com/osr21/arc-relay-bridge/blob/main/docs/mainnet-validation.md
Release: https://github.com/osr21/arc-relay-bridge/releases/tag/v1.0.0-mainnet
Current capabilities
- Arc 5042/domain 26 ↔ Base 8453/domain 6
- Production Circle Iris attestations
- Standard seven-parameter CCTP V2 burn and destination mint
- Persistent, resumable transfer state
- Receipt recovery after wallet RPC failures
- Unique source/Iris message correlation and nonce replay checks
- Destination gas preflight
- Real 0.10 USDC round-trip validation with public transaction links
Safety scope
The standard bridge charges no application fee. Relay, gasless, refuel, yield, and all testnet runtime access are disabled. The project is open source under Apache-2.0 and has not received an independent security audit.
Please advise whether this fits the Arc ecosystem listing process and whether any additional metadata or review is required.
