FAQ

Common questions.

What does non-custodial mean?
You keep your funds in your own wallet at all times. We build the swap, your wallet signs it, and funds move directly between you and the liquidity provider.
Do I need to sign up?
Yes, create an account and complete a one-time identity verification before first swap. After that, connect your wallet and trade in seconds.
Is KYC required?
Yes. As a registered Money Services Business, Cardiful is required by law to verify the identity of every user. Verification is a one-time process and takes a few minutes. Sanctioned and restricted jurisdictions are not eligible.
Which wallets are supported?
MetaMask, Ledger, Trezor, Phantom, Rabby, Rainbow, WalletConnect, Coinbase Wallet, and any EVM-compatible wallet.
How fast is a swap?
On-chain swaps typically confirm in 15 seconds to 5 minutes depending on the network and gas price you choose.
What if a swap fails?
Your funds stay in your wallet. You only pay the network fee for the failed attempt.
