Everything you need to accept crypto payments

One gateway from the first invoice to the withdrawal. No node, no wallet rotation, no manual reconciliation.

Price an invoice in USD, EUR, TRY, RUB, GBP, AED or directly in crypto; the rate is locked for the invoice lifetime. Redirect from your checkout or send the payment link in a chat or e-mail.

Hosted checkout

A ready-made payment page with QR code, exact amount, countdown and live status. The customer picks the coin and network. No customer account or wallet connection needed.

Confirmed payments are credited per asset, net of your commission. Request a withdrawal to your own address at any time; every movement is recorded with its transaction hash.

Security

Security and control by design

Payment edge cases and API access are handled by the gateway, not left to you.

Rate locked per invoice

The exchange rate is fixed when the invoice is created and holds for its whole lifetime.

Automatic matching

Unique amounts per address match each transfer to its invoice. Late or unmatched transfers are held for review instead of being credited blindly.

Underpaid & overpaid handling

Configurable underpayment tolerance, partial payments that add up and overpayments flagged separately. Every case is visible in your dashboard.

Signed, restricted API

HMAC signatures with a short timestamp window, revocable API keys and an optional IP allow-list.

Append-only ledger

Balances come from an append-only ledger: every credit, commission and withdrawal is traceable.

Reviewed withdrawals

The amount is reserved immediately, sent after approval and recorded with its transaction hash.

What is a crypto payment gateway?

A crypto payment gateway lets a business accept cryptocurrency without running its own node or wallets. With mistKET you create invoices through our API or panel, your customers pay on our hosted checkout, and we detect the payment on-chain, notify your server with a signed webhook and credit your merchant balance.

How much does mistKET cost?

There is no setup or monthly fee. You pay a commission only on confirmed payments: rates start from 0.5% and the standard rate is 2.49%. Expired or unpaid invoices are free, and higher volumes get lower rates.

Who holds the funds?

Customer payments arrive at deposit addresses operated by mistKET. Each confirmed payment is credited to your merchant balance in our ledger, net of the fee, and you can request a payout to your own wallet address at any time.

Which assets and networks are supported?

Currently supported: USDT (TRC-20). Other assets and networks can be enabled on request.

How fast are payments confirmed?

On TRON (TRC-20), the network enabled today, payments usually confirm in about a minute. Your webhook is sent as soon as the required confirmations are reached.

What happens if a customer pays the wrong amount?

Within your tolerance the invoice is accepted. Otherwise it is marked underpaid (the customer can top up) or overpaid, and you get a webhook with expected and received amounts. Every case is visible in your dashboard for a decision.

How do I integrate?

Any system that can send HTTPS requests can integrate: one signed POST to create an invoice and one webhook endpoint to receive status updates. The full reference with PHP, Node.js and Python examples is in the API docs.

Can you integrate mistKET for me?

Yes. If you do not have a developer, our team can set up the integration for your website, online store or Telegram bot free of charge: invoice creation, the redirect to the checkout and the webhook that marks orders as paid. Write to us on Telegram or open a support ticket.

How do I start accepting payments?

Create an account, add your project (website or Telegram bot) and wait for our team to review it. Once it is approved you create API keys in the panel and start issuing invoices.

How do payouts work?

Request a payout from the panel for any asset you hold a balance in. The amount is reserved immediately, sent to your address after approval and recorded with its transaction hash.

Can I accept USDT payments in a Telegram bot?

Yes. Your bot calls the same API to create an invoice, sends the customer the payment link and delivers the order when the signed webhook arrives. No customer account or wallet connection is needed.

Is there public documentation for the crypto payment API?

Yes. The API docs cover creating and querying invoices, HMAC-SHA256 request signing, webhook events and retries, error codes and ready-to-use PHP, Node.js and Python examples.
