Move assets to and from Base using the routes below. Pick the one that matches where your assets are today.

​
Choose a Route

Fast bridges and aggregators are third-party services with their own trust model. Compare them with the standard bridge in Compare Bridge Types.
If you hold funds in a Coinbase account, you can withdraw many assets straight onto the Base network — select Base as the network when withdrawing, no bridge required. This is often the fastest path for USDC and ETH.

​
Compare Bridge Types

Bridges to and from Base fall into three types. They differ in speed and in who you trust to deliver your funds. The finalization window applies only to standard bridge withdrawals from Base to Ethereum; standard bridge deposits from Ethereum to Base do not wait for it. To see why the window exists, read Withdrawals.

​
From Ethereum

Bridge ETH and supported ERC-20s between Ethereum mainnet (L1) and Base. Both providers support mainnet and Sepolia testnet.

Superbridge

Bridge ETH and supported assets from L1 to Base. Testnet

Brid.gg

An alternative L1 ↔ Base bridge. Testnet
Withdrawals from Base to Ethereum through the standard bridge wait for the finalization window shown in Compare Bridge Types. Superbridge can also route through third-party bridges; check which route it selects before you confirm.

​
Programmatic Bridging

To bridge ETH and ERC-20s from Ethereum to Base in code, start from the sample repository.
Double-check the token address for ERC-20s. Confirm the token has a base entry in the Superchain token list (example), and always test with small amounts first. This sample bridges assets to Base only — do not modify it to withdraw.

​
For Token Issuers

To make an ERC-20 on Ethereum bridgeable to Base through the standard bridge, use the sample repository above as a starting point for the standard bridge contracts, then list your token on the Superchain token list. To issue one token across Base and other chains, use a cross-chain messaging protocol.

​
Fast Bridges

Fast bridges move assets between Base, Ethereum, and other chains in both directions, typically in seconds to minutes. Providers pay you out from liquidity on the destination chain, then settle through their own mechanism.
Fast bridges do not inherit Base’s security. Your funds depend on the provider’s contracts, relayers, and liquidity, and fees vary by route and size. Review the provider’s security model, supported assets, and fees, and test with a small amount first.

​
Bridge Aggregators

Aggregators quote routes across many bridges and pick one for you, which helps when you are coming from a chain without a direct route to Base. The route’s security depends on the bridge the aggregator selects, so check which bridge it uses before you confirm.

Jumper

Bridge and swap aggregator built on LI.FI.

Bungee

Bridge and swap aggregator built on Socket.

​
Cross-Chain Messaging Protocols

Cross-chain messaging protocols let a token issuer deploy one token across Base and other chains. Both of these support Base Mainnet: On LayerZero, Base Mainnet is endpoint ID 30184; see deployed contracts. A token issued this way is secured by the protocol’s own network, not by Base’s standard bridge. Choose the protocol and its security settings before launch.

​
From Solana

The Base–Solana bridge enables bidirectional token transfers and message passing between Base and Solana: move SOL and SPL tokens, send cross-chain messages, deploy wrapped tokens on either chain, and optionally auto-relay for instant execution.

From Bitcoin

Garden is a fast, non-custodial bridge for moving BTC and other supported assets to Base. Available on mainnet and Sepolia testnet.
The bridge previously at bridge.base.org has been deprecated. Use the routes above instead.
