Start Your Crypto Payment Journey
Uapi is a unified crypto payment infrastructure. Whether you want a fully automated online store or just a payment link, we have you covered.
A non-custodial crypto payment gateway built for indie developers, freelancers, and SMEs. We provide a complete solution that lets you receive USDT (TRC20/ERC20/BSC) directly in your own on-chain wallet without relying on centralized intermediaries, with automatic order matching and bookkeeping.
Core Value
Direct Settlement
Funds go straight to your private-key wallet with no middleman, no withdrawal step, and no freezing risk.
Privacy & Security
No cumbersome KYC process. Protect your transaction privacy with fully automated, reliable on-chain monitoring.
Automated Finance
No more manual reconciliation. The system auto-detects transfers, links orders, and produces clear financial records.
Complete Sales & Finance Records in Your On-Chain Wallet
This is the core module of Uapi, designed to solve the pain points of collecting payments, reconciling records, and bookkeeping.
What is the pain point?
When receiving funds with a personal wallet, it becomes difficult to identify which transfer belongs to which customer or product. Manual TX hash reconciliation is inefficient and error-prone.
Unique Amount Matching
When you create an order, the system adds a tiny random decimal to the base amount (e.g. 100.00 -> 100.001234), making each unpaid order amount globally unique.
24/7 On-Chain Monitoring
Our high-performance nodes monitor your receiving wallet around the clock. Once a transfer that exactly matches order amount is detected, the system locks that transaction immediately.
Auto Reconciliation & Archiving
The system automatically binds TX hash, payer address, and payment timestamp to your merchant order, then updates status to paid.

Frequently Asked Questions
Are funds truly safe?
Absolutely safe. We never ask for, store, or touch your private key. You only provide your public receiving address in the dashboard. Funds are confirmed by the blockchain and sent directly to your address. Uapi only acts as an observer to notify payment results.
How do I get started?
- Sign up and log in to the merchant dashboard.
- Add your USDT receiving wallet in API Settings or Wallet Management.
- Create a payment link for testing, or integrate via API documentation.
- Start collecting payments.
What if users pay the wrong amount?
The system checks paid amount automatically. If the amount is mismatched (underpaid or overpaid), the order will not be auto-marked as paid. You can handle it manually in Order Management after checking hash details.
