...As a trustless bridge, Hop allows users to force exit their tokens in the rare event where Bonders (market makers) don’t bond a user’s transfer fast enough. Hop offers users a fallback option to withdraw their tokens manually at the destination chain albeit not as fast as it would arrive in a normal transfer involving a fully functioning Bonder. In order to withdraw, the Transfer Root bundle containing the proof of your transaction must be propagated to the destination, and this could take a few hours or days depending on the asset and route, so withdrawing immediately after sending won't work.
