What is the Superbridge?
The Superbridge is your entrypoint into the world of blockchain rollups! With the Superbridge you can bridge Ether and other tokens into and out of any supported rollup. Usually these rollups are built on top of Ethereum but not always.
The main thing you're going to be doing with the Superbridge will be bridging assets between base chains, like Ethereum Mainnet, and rollups, like Optimism, Arbitrum, Base, Zora, etc.
You can get the full benefit of Ethereum's censorship resistance with our Forced Withdrawals feature. These withdrawals cost a little more gas, because the initiating transaction needs to go via Ethereum.
You can read more about Forced Withdrawals and how they work in the context of OP rollups here
If you don't want to deal with the hassle of sending multiple transactions and remembering to come back to finalize a withdrawal 7 days later, Easy Mode is for you. For a small fee (to cover gas costs) when initiating your withdrawal we'll will handle relaying your withdrawal to Ethereum mainnet and even refund you any leftover ETH!
