Non-custodial swap

A non-custodial swap is a crypto-to-crypto exchange in which the routing service never gains custody of the funds being swapped. The user initiates the swap from their own wallet, deposits the source asset directly to an address controlled by the executing provider, and the destination asset is sent to a receiving address the user specified. At no point does the routing platform hold a balance on the user's behalf.

The critical distinction is legal and technical. Legally, a non-custodial platform typically does not fall under the same "money transmission" and "custodial wallet" regulations as a custodial exchange in most jurisdictions — because it never possesses user funds. Technically, this eliminates a class of counterparty risks: the platform cannot lose keys, cannot be subpoenaed to freeze balances (there are no balances), and cannot be hacked out of user funds directly.

Non-custodial does not automatically mean trustless. The user still relies on the executing exchange provider to complete the swap at the agreed rate, and on the routing platform to accurately quote the provider. Rate slippage, provider outages, and pricing spreads still exist. What is eliminated is the specific "the platform is holding my money" risk.

SwapZilla is non-custodial across every product: swap, payment links, batch payouts, and payroll. Each swap routes directly between the payer, the executing provider, and the recipient wallet the user or merchant specified. Nothing sits on a SwapZilla-controlled address.
