Everything to take payments and get paid
Rouble bank transfers
Payers get a payment page with your logo and colour, the exact amount, payment details and a timer.
USDT TRC-20
Permanent addresses for your customers: any amount is credited after independent transaction checks.
API, webhooks and sandbox
Rotating keys, signed events with retries, test payments without real money.
Payouts in USDT
Withdrawals to pre-approved addresses, auto-payout rules and confirmation of large amounts.
Process payments and earn a commission
Collateral-backed
USDT collateral is reserved for each payment and released if the payment never arrives.
Shifts and payment details
You open a shift and choose your payment details; limits keep the load manageable.
Notifications
New payments and "paid" marks in the dashboard, Telegram and push notifications.
Teams
A team lead automatically earns a share of the commission on the team's payments.
From order to credit in four steps
Order via API
Your site creates a payment and receives a signed link to the payment page.
Details and amount
Relay picks an available trader with collateral and locks the rate and tariff.
Payer transfer
The payer sends the exact amount and taps "I paid"; the trader confirms receipt.
Credit
The merchant balance grows in USDT in one ledger entry and a webhook reports the result.
The financial truth lives only in Relay's ledger
Double-entry ledger
Immutable balanced entries; balances come from the ledger, never from a provider response.
Two blockchain checks
An indexer finds the transfer, an independent node confirms it before any credit.
Passkey for money decisions
Withdrawals and money decisions require a fresh passkey sign-in; every operator action is logged.
No keys on the server
Addresses derive from a public key; transaction signing stays outside the API.
