# Base Bridge

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

> [!WARNING]

>

> The bridge is only live on testnet between Solana Devnet <> Base Sepolia. The code is a WIP and has not yet been audited. Do not use in production!!

## 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](https://docs.base.org/base-chain/network-information/bridges-mainnet).

## Usage

### Base → Solana

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

```bash

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:

```bash

cd solana

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

```

### Solana → Base

Send tokens or messages from Solana to Base:

```bash

cd solana

# See solana/README.md for detailed instructions

```
