# How does my Pro wallet work?


| Your Pro wallet is created and managed through Privy, allowing you to sign in with your email and use on-chain features without installing a browser wallet.

Your wallet on Sport.fun is managed through Privy. Privy quietly sets up a secure smart account for you behind the scenes, so you can sign in with just an email and start playing without any crypto know-how or browser extensions. 

Pro is built on top of Base, an Ethereum Layer 2 network, which means everything you hold and trade lives on-chain in auditable smart contracts.

|| Free to Play does not use a wallet, deposits or withdrawals. Its Gold exists only inside the game.

### Keep your wallet safe

* Copy addresses directly from the app.
* Check the token and network before every transfer.
* Use a small test transfer when sending to a new address.
* Never share a password, verification code, private key or recovery phrase.
* Sport.fun will never contact you first and ask you to transfer funds.
