USDT Payment Detection & Order Status Integration

Need to accept USDT on your website without turning your team into a blockchain operations desk? I build the web and backend side of USDT payment detection: create an order, show a payment address or QR code, detect the expected transfer, apply a confirmation policy, and update the order status for your application and admin team.

What I can implement:

• Payment-intent creation with a unique order reference and expected amount
• USDT address or QR display supplied by your wallet or payment provider
• Read-only transaction lookup through a trusted RPC provider or payment API
• Network and contract checks, amount matching, and configurable confirmation thresholds
• Webhook and polling pipelines with idempotency, retries, and audit logs
• Order states: pending, detected, confirmed, underpaid, expired, or failed
• Admin views for payment status, transaction references, and manual review
• Docker deployment, monitoring hooks, and runbook documentation

The integration can be added to an existing Spring Boot or Node.js application or delivered as a small standalone service. I work with non-custodial flows: your wallet or provider controls the funds, and the application only reads public blockchain or provider data. I do not handle private keys, custody customer funds, provide exchange services, or perform smart-contract development or audits.

We start with the target network, asset, confirmation rule, and order workflow. I then build and test against a staging environment before connecting production endpoints.
