Platform
Built for production payments
From the first invoice to the payout: one dashboard, exact figures and a full audit trail.
Hosted checkout
One API call returns a checkout page with a QR code, a unique payment amount and an expiry timer. Incoming transfers are matched on-chain around the clock.

Waiting for payment…
Signed webhooks
Every callback carries an HMAC-SHA256 signature and is retried from a durable queue until your endpoint confirms receipt. Payloads and delivery attempts stay visible in the dashboard, with one-click resend.
Payment links
For teams without a website: create a fixed-amount link and share it in any chat. Each opening creates its own invoice, so every payment stays attributable.
Business wallet
Merchant revenue is held on a separate business balance. 16 assets with permanent deposit addresses across 12 networks.
Payouts
Withdraw to any external address on TRON, BSC or Polygon. The network fee is shown before you confirm, and every payout is reviewed before it is broadcast.
REST API and docs
Create an invoice, redirect the customer to the checkout, receive a signed callback once it is paid.
Integration examples for Node.js and PHP are in the documentation.
# create an invoice
curl -X POST https://fast-pay.money/api/v1/invoice \
-H "Authorization: Bearer fpk_····" \
-d '{ "amount": 20, "order_id": "ORDER-1001" }'
# → { "uuid": "6e24…", "url": "…/pay/6e24…" }
Why FastPay
What you get
0.5% per payment and nothing on top: no monthly charge, no setup fee, no minimum turnover.
Onboarding without documents
No passport scans, no company papers, no interview. Register, confirm domain ownership and accept
your first payment the same day.
One flat fee
One fee per payment, shown before you accept it. No monthly charge, no setup fee, no cut
taken from withdrawals beyond the network cost.
16 assets, 12 networks
USDT, USDC, DAI, BTC, ETH, BNB, TRX, SOL, TON and more. Your customer pays in whatever they
hold; you are credited in the same coin.
Funds stay available
Nothing is frozen, held back or locked for a waiting period. Ask for a withdrawal at any
time and it goes out the same day.
Onboarding
