Sandbox Failure Reasons
Transaction processing failed may happen when the testnet wallet is empty or you used the wrong card. Please reach out to your MoonPay representative.Your Region is Not Supported means MoonPay may not support your country or the cryptocurrency is unsupported in your region. New York, USA is not supported in sandbox but is supported in production.You've made too many actions or You can't perform this action means you have been rate limited. This happens when we detect unusual behavior and is not uncommon for partners to experience this while testing. The recommendation is to wait ~20 minutes before trying again.Account is restricted or blocked may happen if you are using a production MoonPay user account in sandbox or entered otherwise triggered one of our automated flags for suspicious behavior.
Empty testnet wallet
An empty testnet wallet will result in a Transaction processing failed error when you and other developers try to complete transactions. You may top up the wallet with your own testnet coins or use any available online faucet to top up Sepolia ETH.
