What non-custodial means for merchant payments
In a custodial gateway, customer deposits usually enter wallets controlled by the payment provider before they are later settled to the merchant. That model may be convenient, but it creates counterparty risk, operational dependency, and additional compliance exposure.
A non-custodial gateway changes the control model: the payment layer can detect deposits and update order status, while the merchant keeps control of the receiving wallet, signing policy, and settlement path.
Why dedicated user addresses improve deposit matching
Many crypto deposit systems rely on memos, tags, remarks, or manual screenshots. Those workflows break when users forget the memo, withdraw from an exchange that hides notes, or send multiple payments from different wallets.
WARMKEY’s 1 user 1 address model gives every customer a stable deposit address, so address identity becomes the reconciliation key. This reduces support tickets and creates a clearer audit trail.
How WARMKEY fits into a payment stack
A typical integration starts by creating or retrieving the customer’s dedicated deposit address. The merchant page displays that address, the backend checks payment status, and the order or balance is updated once on-chain conditions are met.
Settlement remains under the merchant’s controlled wallet and signing flow, so teams can add crypto deposit automation without building a full blockchain monitoring and reconciliation stack from scratch.
Security and AML risk isolation benefits
Dedicated addresses also help isolate risk. If a single user address receives suspicious funds, the merchant can review that user’s activity without mixing the signal into a shared pooled wallet.
This does not replace compliance operations, but it gives teams cleaner evidence for AML review, transaction analysis, and account-level controls.
