FAQ
What is a cold wallet payment gateway?
It is a payment workflow where deposit detection and merchant operations can be automated while fund custody remains aligned with the merchant’s wallet policy.
Why avoid gateway-held funds?
Gateway-held funds create an extra concentration of risk. Non-custodial and cold-wallet-friendly designs reduce that exposure.
Is this suitable for high-value merchants?
Yes. The model is especially relevant for teams that need risk separation, auditability, and wallet-control discipline.
