# BTC Bridge (Alpha Mainnet)

## Prerequisites

Before starting the bridging process between Bitcoin and SatoshiVM Alpha Mainnet, ensure the following:

1. [**MetaMask Wallet**](/user-guide/testnet/wallet-setup.md)**:** Have MetaMask installed and configured to interact with the SatoshiVM.
2. [**UniSat Wallet**](/user-guide/testnet/faucet/bridge-from-bitcoin.md#wallet-setup-via-unisat)**:** Ensure your UniSat wallet is ready for the transaction process.

## Deposit: Bridge BTC to SatoshiVM

### 1. Navigate to the official BTC Bridge

Access the official [BTC Bridge page](https://bridge.satoshivm.io/). This is where you'll be initiating the process of transferring BTC from Bitcoin to SatoshiVM Alpha Mainnet.
