Everything you need to know before your first swap.
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. Cardiful never holds your assets.
Do I need to sign up?+
No account needed. Connect a wallet and you are ready to trade. No email, no password, no KYC for standard swaps.
Is KYC required?+
No KYC for standard swaps. Certain large cross-border trades may trigger verification depending on the network and the regulated liquidity source involved.
Which wallets are supported?+
MetaMask, Ledger, Trezor, Phantom, Rabby, Rainbow, WalletConnect, Coinbase Wallet, Keplr, Xverse, and any EVM-compatible, Solana, or Bitcoin 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. Bitcoin swaps take longer by nature.
What if a swap fails?+
Your funds stay in your wallet. You only pay the network fee for the failed attempt. Nothing leaves your wallet without a successful swap.
Is there an API?+
Yes. Public REST and WebSocket endpoints for quotes, routing, and transaction submission. Free tier, no API key for public endpoints.
Can I run my own node?+
Yes. The protocol is open source. You can self-host the swap engine and skip our hosted frontend entirely.
