Enable Test Mode

Developers can turn on Test Mode to test both fiat-to-crypto transactions and crypto-to-crypto transactions on supported testnet chains. It is possible to test both at the same time or separately.

Buy With Fiat

By setting testMode to true for Buy With Fiat, you can enable test experiences for our underlying providers (Stripe, Kado, and Transak).


<ConnectButton
  client={client}
  detailsModal={{
    payOptions: {
      buyWithFiat: {
        testMode: true, // defaults to false
      },
    },
  }}
/>;

For Coinbase onramp, you can turn on "Mocked mode" when launching the Onramp experience.

At the bottom of the Onramp modal where it says "Secured by Coinbase", click 10 times on the word "Secured." This will navigate you to Onramp's Debug Menu. There, navigate to the Actions tab click on the toggle for "Enable Mocked Buy and Send." You can now exit the Debug Menu and proceed with mock buys and sends. Remember to click on the "Enable Mocked Buy and Send" toggle once you are done to enable actual buys and sends.
