Funds settle to the merchant wallet
The payment address belongs to the merchant configuration, so settlement does not depend on a platform balance or later withdrawal request.

- 02
The backend creates a payment order with the exact amount, network, wallet address, notifyUrl, and returnUrl.
- 03
The customer sends USDT directly to the merchant-controlled destination address.
- 04
BoltUtil monitors the chain, matches successful transfers, and sends a signed webhook after confirmation.
Automation without custody
BoltUtil provides order matching, confirmation tracking, and webhook delivery while the merchant remains responsible for wallet ownership.
Clear audit trail
Every completed order can be reconciled with network, token contract, amount, destination address, confirmations, and transaction hash.
Integration notes
What matters before production
Non-custodial does not mean unverified
The gateway still needs strict checks for network, token contract, destination address, exact amount, order state, and confirmations.
Webhook security still matters
Merchant systems should verify callback signatures and make fulfillment idempotent before granting access or shipping goods.
Wallet operations need discipline
Use clear wallet ownership, backup, monitoring, and finance reconciliation practices because funds arrive directly in the merchant wallet.
Questions merchants ask before going live
These answers help developers, founders, and support teams understand the payment lifecycle before accepting real USDT payments.
What does non-custodial USDT payment mean? +
It means customer funds are sent directly to the merchant wallet. The gateway monitors the blockchain and sends payment notifications instead of holding funds.
Can a non-custodial gateway still automate checkout? +
Yes. Automation comes from order creation, transfer matching, confirmation checks, and signed webhooks, not from holding merchant funds.
Is non-custodial checkout safer for merchants? +
It reduces platform custody risk, but merchants still need secure wallet management, signature verification, idempotent fulfillment, and reconciliation.
