# Bridge Mode's canonical bridge is a fork of Optimism's bridge. The bridge only allows moving funds from Mode to Ethereum Mainnet and viceversa. The tokens supported for now are ETH, USDC, USDT and WBTC.\ \ The ETH bridged from Ethereum mainnet to Mode is ETH on Mode mainnet as well, it's not a wrapped version as it is the base token of Mode. We refer to "Deposit" when bridging from L1 to the L2 - [Bridge to Mode](/user-guides/bridge/bridge-to-mode.md)\ \ We refer to "Withdrawal" when bridging from L2 to the L1 - [Bridge from Mode](/user-guides/bridge/bridge-from-mode.md)\\ --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
