Canonical vs Third-Party Bridges

When you move assets to a rollup or new chain, you often face two routes: the official bridge maintained by the protocol team, or a third-party router that promises faster settlement through liquidity pools and relayers. The choice is a tradeoff between aligned security and optimized speed.

Canonical bridges are the default for treasuries and large personal transfers. They are slower because security mechanisms — fraud proofs, challenge windows, validator quorums — take time to enforce honestly.

Third-party bridges earn fees by bearing timing risk. A liquidity provider fronts tokens on the destination while waiting for finality on the source. That is convenient until the pool is drained, the relayer lies, or the contract has an unaudited code path.
