Payment matching
→Enter a transaction hash or transfer facts, then compare network, destination address, exact amount, order status, and confirmations to understand why a payment matched or did not match.
Callback testing
→Generate a standard webhook payload, HMAC-SHA256 signature, and cURL command to reproduce server-side signature checks, raw body handling, and retry behavior.
Crypto directory
→Block explorers, market data, exchanges, on-chain analytics, developer tools, and wallet safety links organized around payment operations.
Use cases
When a customer says they paid, an order remains pending, or a webhook reached your endpoint but the application did not update, these tools turn the investigation into verifiable facts.
Use the transaction checker to compare explorer facts with order facts before manually releasing or adjusting anything.
Check network, token contract, exact amount, destination address, expiration window, and confirmation depth.
Use the webhook tester to reproduce the callback, signature headers, and raw body your endpoint expects.
Confirm your endpoint returns non-2xx only for retryable failures and 2xx after the business state has been durably processed.
FAQ
Choose the right diagnostic path with fewer steps and avoid trial-and-error on production orders.
Use the USDT Transaction Checker first. It helps compare the transaction hash, selected network, destination address, transfer amount, order status, and confirmation count.
Use the Webhook Tester when the payment is complete but your application did not update, or when signature verification fails.
No. The public tools are diagnostic helpers. They do not mark orders as paid, send customer notifications, or trigger production webhooks.
