Features

Built for real-world checkout

From order creation and amount locking to on-chain settlement and signed callbacks — every step is visible, queryable and reconcilable, so anomalies can be pinpointed the moment they happen.

Multi-chain, multi-token

USDT, USDC, TRX, SOL, TON and more across TRC20, ERC20, BEP20, Solana, TON and other networks.

Non-custodial

You hold the keys and the funds throughout — no escrow risk, no platform cut.

Fast onboarding

Three standard interfaces plus 10+ ready-made integrations (Dujiaoka, V2Board, WHMCS, WordPress and more) — a few lines of server code and you are live.

Automatic address assignment

Every order locks an address-plus-amount slot, so you never maintain address pools or reconciliation scripts by hand.

Reliable callbacks

Failed deliveries retry with backoff, with signature verification and manual resend — no missed orders.

Merchant console

Orders, API keys, receiving wallets, balance, invoices and sub-users — all in one console.

Clean reconciliation

Platform transaction ids, on-chain hashes, received amounts and the balance ledger are all traceable.

Real-time notifications

Successful payments, anomalies and daily reports pushed through Telegram, Webhook or email.

Networks & tokens

Major networks, chosen per order

Pass token and network when you create an order; payers can also switch network and token themselves on the checkout page — no per-chain work on your side.

Global reach

Stablecoin settlement, wherever you do business

USDT and USDC settle on major public chains within minutes — no bank corridors, no cross-border fees, available around the clock.

Live settlement

Confirmed on-chain, settles instantly — no T+N settlement window

No bank corridors needed

Funds skip banks and card networks — no geographic or FX-quota limits

24/7 confirmation

Watched and confirmed around the clock

Transparent fees

Only the on-chain network fee applies

Callbacks that never drop, exceptions you can handle

Once a payment is confirmed, the platform delivers a signed callback to your server — every step from delivery to final acknowledgement is traceable in the merchant console.

  • Callbacks are signed — verify them server-side to block forgeries
  • Failed deliveries retry with backoff; idempotency checks prevent double-crediting
  • Every delivery attempt is logged, with manual resend and close

Integrations

Broadly compatible, plug and play

Already integrated with popular card-selling, proxy-panel and website systems — the protocol is compatible, so you do not rework your business logic.

EPay compatible

Fully EPay-compatible, MD5 signing included — switch the gateway URL, no code changes.

Smart Contract

Smart-contract hosted payments plug in with zero code changes — signed callbacks reconcile automatically.

Simple HTTP API

One HTTPS call creates an order and returns the address and amount due — live in 10 minutes.

How it works

Four steps to get paid

Follow a single 20.05 USDT order through the whole journey — from one API call on your server to an on-chain transfer, automatic matching and a signed callback, with no manual reconciliation along the way.

  1. 01

    Create the order

    Your server calls the order endpoint and receives the amount due plus a receiving address.

  2. 02

    Amount locked

    The platform locks an address-and-amount slot, valid for 30 minutes by default.

  3. 03

    Wait for the transfer

    The payer transfers the exact amount; the platform watches the chain and matches it.

  4. 04

    Callback

    Once confirmed, your service is notified via a signed callback.
