Use cases

Start with the right tool

Choose a tool, then check the payment or webhook.

A customer says they paid

Look up the transaction hash and check its destination and amount.

An order is still pending

Compare the order status, payment amount, and confirmation requirements you enter.

A webhook signature fails

Check the timestamp and raw request body, then generate a signature for comparison.

You need on-chain records

Select a network and open its explorer with an address or transaction hash.

FAQ

A few things to know

These tools help you investigate. Confirm actual order status in your dashboard and on-chain records.

Does a passing check mean an order is paid?

No. The checker compares the information you enter; it does not verify that an order exists. Confirm the final status in your merchant dashboard and on-chain records.

Which stablecoins and networks can I check?

USDT queries cover all six networks. USDC queries cover Ethereum, BNB Smart Chain, Polygon, Solana and Base; TRON supports USDT only. Queries use the token contract or mint configured by BoltUtil.

Does the webhook tester send callbacks or retry automatically?

No. Signatures are generated in your browser. The page provides an example body, signature, and cURL command. Run requests and test retry logic in your own test environment.

Will these tools change production orders?

The tool pages do not change BoltUtil orders or send callbacks automatically. Running a generated cURL command sends a request to the address you entered, so use a test environment.
