Privy makes it easy to allow your users to fund their embedded wallets with convenient payment methods like Apple Pay and Google Pay via @privy-io/expo and on the web through @privy-io/react-auth. This guide will walk you through setting up Privy’s funding flows, allowing your users to fund their wallets quickly and easily in under two minutes. card-based-funding
Card and fiat on-ramp purchases are supported on mainnets only. On testnets (e.g. Polygon Amoy, Sepolia), on-ramps cannot purchase testnet tokens, so this flow will not be shown or will fail.

​
1. Enable debit card funding in the Dashboard

In the Privy Dashboard, enable Pay with card on the User management > Account funding page. With this option enabled, if Apple Pay or Google Pay is available on your user’s device, Privy will provide users the option to purchase with those methods. Choose your desired network across EVM and Solana and set a recommended amount for users to fund. Users can update the amount manually if they choose.

​
2. Prompt the user to fund

​
@privy-io/react-auth

Prompt the user to fund by calling fundWallet
