Base Bridge

A bridge between Base and blockchains outside the Ethereum ecosystem. Currently has support for Solana.

How it Works

This bridge allows you to:

• Transfer tokens between Base and Solana
• Send arbitrary cross-chain messages
• Deploy wrapped tokens on either chain

Note

For native Ethereum ↔ Base bridging, see our official docs.

Usage

Base → Solana

Send tokens or messages from Base to Solana (multi-step process):

cd base
# See base/README.md for detailed instructions

After initiating on Base, wait ~15 minutes for an updated root to be posted to Solana and complete the transfer with prove + finalize steps:

cd solana
# See solana/README.md for prove and finalize instructions

Solana → Base

Send tokens or messages from Solana to Base:

cd solana
# See solana/README.md for detailed instructions

Gas Fee Receiver Address

Some cross-chain operations performed by the Base Bridge require gas fees. These fees are sent to a designated gas fee receiver address, which is used to cover relaying and execution costs during the bridging process.

Note

The gas fee receiver address is network-specific and may differ between devnet, testnet, and mainnet environments.
