# SAVM Bridge (Alpha Mainnet)

## Prerequisites

### MetaMask Wallet

Have MetaMask installed and configured to interact with the SatoshiVM Alpha Mainnet.

{% hint style="info" %}
MetaMask has automatically added the configuration for the Ethereum.
{% endhint %}

## Deposit: Bridge SAVM from Ethereum to SatoshiVM

### 1. Navigate to the official SAVM Bridge

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

### 3. Deposit on Ethereum

#### 3.1 Enter the amount of an Ethereum asset to deposit

{% hint style="info" %}
Aggregator Functionality:

The default asset is **$SAVM**, and users can also choose other Ethereum assets (such as ETH, USDT, USDC, etc.).

Then SAVM Bridge will automatically swap other assets for **$SAVM** and cross-chain them to SatoshiVM.
{% endhint %}

#### 3.2 Input the desired gas exchange amount (optional)

{% hint style="warning" %}
SatoshiVM Alpha Mainnet operates with **BTC for gas fees**. After transferring SAVM from Ethereum to SatoshiVM Alpha Mainnet, users may **lack gas**. They can exchange SAVM for BTC on this interface to facilitate operations.

Alternatively, cross-chain BTC to SatoshiVM Alpha Mainnet via the [BTC Bridge](/user-guide/alpha-mainnet/btc-bridge-alpha-mainnet.md) if not exchanging BTC for gas fees here.
{% endhint %}
