API integration flow

Best for developers integrating crypto payments into SaaS, marketplaces, membership systems, or custom checkout flows.

  1. 01

    Create a payment order with amount, network, order ID, and return URL.

  2. 02

    Show the generated checkout URL, wallet address, QR code, and exact USDT amount to the buyer.

  3. 03

    BoltUtil scans TRC20, ERC20, or BEP20 transfers and matches the order by network, address, and amount.

  4. 04

    After confirmation, BoltUtil sends a signed webhook to your server with the transaction hash and status.

Non-custodial settlement

Payments go to the merchant wallet you configure. BoltUtil monitors chain activity and does not need to hold user funds.

Three USDT networks

Accept USDT on TRC20, ERC20, and BEP20 with a single order API and unified webhook payload.

Webhook-first automation

Your system receives a signed callback when a transaction is detected and confirmed on-chain.

The current production focus is TRC20, ERC20, and BEP20.
