Credits are paid for with stablecoins straight from your OpenFinance wallet: USDC or USDT on Solana, USDC on Base, or USDG on Robinhood Chain. There is no card form and no separate checkout. You pick a network and a coin, enter an amount, and the app sends it and adds the credits to your balance.

What you need

Have one of these in your OpenFinance wallet, plus a little gas on the same network: Not funded yet? Deposit to your EVM address for Base or Robinhood Chain, or to your Solana address for Solana. A network that is not accepting payments yet shows Soon in the sheet.

If the button will not go
