Crypto Payment Gateway
A production-ready crypto payment gateway built on smart contracts. No intermediaries — payments go directly from buyer to merchant wallet via verifiable on-chain transactions. The gateway supports TON, USDT (TRC20, ERC20, TON native), ETH, BNB and any EVM-compatible token.
Includes a payment widget embeddable in any frontend, webhook system for backend confirmation, and a transaction monitoring dashboard. Battle-tested in production Telegram Mini Apps handling real crypto payments.
