Cross-border payments with fewer middlemen
Accept USDT and USDC, get notified when payments arrive, and have funds swept to your wallet automatically. Hosted checkout and invoices are on the way, so you can get paid without building a payment page.
The problem
Sound familiar?
Too many hops in cross-border settlement
Payments pass through several intermediaries, arriving late with fees that are hard to see.
Orders and payments don’t line up
A transfer arrives and nobody knows which order it belongs to without checking by hand.
No developers to spare
Small team, nobody free to build a checkout.
How PQPA helps
What changes with PQPA
- 01
Direct stablecoin payments
Take USDT and USDC on BNB Chain, Polygon, TRON and Solana, swept to your own wallet automatically.
- 02
Webhooks you can match to orders
Each webhook includes the receiving address, amount and transaction hash, so you can find the order by address and mark it paid once the signature checks out.
- 03
Hosted checkout and invoices (coming soon)
Create an invoice and send the customer a hosted checkout link — no frontend work needed.
Capabilities
What you get
Hosted checkout and invoices
Get paid without building a payment UI: create an invoice and send the payer a hosted checkout link.
Signed webhooks with replay
HMAC-SHA256 signatures you can verify; any missed webhook can be re-sent.
Automatic sweeping and gas top-up
Funds sitting on user addresses are swept to your collection wallet, with gas topped up automatically when needed.
A dedicated deposit address per user
Long-lived, user-specific addresses, so every deposit is matched to the right account.
Merchant and app isolation
Separate books per merchant and per app, so funds from different business lines never mix.
