Bridging ETH from Mode to Ethereum |
Mode's bridge is a fork of Optimism's canonical bridge. With Optimism's Bedrock upgrade, a two-step withdrawal process designed to enhance the safety and integrity of cross-chain transactions was introduced.

The steps to Prove and Finalize withdrawals are executed on Ethereum Mainnet. You will need ETH on Ethereum Mainnet to pay for these fees. This is also why these fees may seem high.
