# Fraxtal Bridge

The bridging process for Fraxtal is derived from that of [Optimism](https://docs.optimism.io/builders/app-developers/bridging/standard-bridge). Assets going from Ethereum Mainnet to Fraxtal (L1StandardBridge & L1ERC721Bridge) usually only take a few minutes, but coming back from Fraxtal to Ethereum (L2StandardBridge & L2ERC721Bridge) can take 7 days. The same applies for messages (L1CrossDomainMessenger & L2CrossDomainMessenger). To mitigate this, Frax Ferry is also available for Fraxtal, and most users will opt to use the Ferry to come back to Ethereum, taking only 24-48 hrs instead of 7 days.
