Why AMPR

Why merchants choose AMPR

Payment infrastructure without the custodial baggage.

No custody, no counterparty risk

We never hold a key that can move your funds. If AMPR vanished tomorrow, your money would be exactly where it has always been — in your wallet.

No chargebacks

On-chain settlement is final. No disputes, no rolling reserves, no processor freezing your balance.

Onboard in under a minute

Fully self-service: sign up, get an API key and send your first invoice — no sales calls, no paperwork.

Wallet-connect & QR on every invoice

Payers connect a wallet in one tap or scan a QR / copy an address. Both flows on every hosted invoice.

Built for developers

Signed webhooks, idempotent retries and a zero-dependency TypeScript SDK. Integrate in an afternoon.

Compliance built in

Sanctions screening runs before any payment is confirmed. Flagged funds never settle silently.

Double-entry transparency

Every movement is recorded in a double-entry ledger — every unit accounted for, auditable at any time.

Checkout in 6 languages

Hosted checkout speaks English, Russian, Korean, Uzbek, Spanish and Turkish — chosen automatically for each payer.

Integration

How it works

Three steps from API call to settled payment.

Create an invoice

One POST to /v1/invoices returns a hosted checkout link you can drop into any flow.

Your customer pays

They connect a wallet or scan the QR and pay on-chain — straight to your address.

You get a signed webhook

We confirm on-chain, fire a signed webhook and your order ships. Done.

Developers

One request to get paid

Create an invoice and share the checkout link — that is the whole integration.

curl -X POST $AMPR_URL/v1/invoices \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"price":"49.99","currency":"USD","assets":[{"asset":"USDT_TRON"}]}'
