The bridge relies on the [message service](/protocol/architecture/interoperability/canonical-message-service) for cross-chain interactions. ## Next steps - See the UI for the [official public Linea bridge](https://linea.build/hub/bridge/). - For the public network's workflow, ABI references, and bridge interfaces, see the [canonical token bridge guide](/network/build/bridge) and [contracts](/network/build/contracts).
