# Wallets & Networks

To use R2E, you need a MetaMask wallet that is connected to Binance Smart Chain. For more info about MetaMask, please visit their website <https://metamask.io>

MetaMask by default only supports the Binance Smart Chain and allows you to send and receive coins. However, when you connect MetaMask to R2E, R2E will automatically configure MetaMask to work with Binance Smart Chain.

You can connect to these two networks to start your R2E adventure, with Binance Smart Chain as mainnet product, and Binance Smart Chain Testnet as beta testing network.
