Bridges
Learn how to bridge assets between Abstract and Ethereum.
A bridge is a tool that allows users to move assets such as ETH from Ethereum to Abstract and vice versa. Under the hood, bridging works by having two smart contracts deployed:
- A smart contract deployed to Ethereum (L1).
- A smart contract deployed to Abstract (L2).
These smart contracts communicate with each other to facilitate the deposit and withdrawal of assets between the two chains.
Native Bridge
Abstract has a native bridge to move assets between Ethereum and Abstract for free (excluding gas fees) that supports bridging both ETH and ERC-20 tokens.
Deposits from L1 to L2 take around ~15 minutes, whereas withdrawals from L2 to L1 currently take up to 24 hours due to the built-in withdrawal delay.

Third Party Bridges
In addition to the native bridge, users can also utilize third-party bridges to move assets between Ethereum and Abstract. These bridges offer alternative routes and may come with different features but also have different risks.
Relay
Relay provides near-instant transfers between Ethereum and Abstract for a small fee. It works by connecting users with relayers that act on users’ behalfs across chains in exchange for a small fee.
