How it works
On-chain payment verification for business
TRXN connects your invoices to the blockchain. Create products and prices in fiat, generate invoices, and let TRXN verify payments on-chain across BTC, ETH, and POL.
Capabilities
The on-chain payment pipeline for business
From product definition to payment verification, TRXN handles every step between your business logic and the blockchain.
Fiat pricing, crypto collection
Set your prices in USD (more fiat currencies on the way). Customers pay in crypto at real-time exchange rates from providers like CoinMarketCap and CoinAPI.
On-chain verification
TRXN monitors blockchain data sources to verify that payments match your invoices by amount, address, and timeframe.
Slippage margin handling
Crypto prices move between checkout and confirmation. Configurable slippage tolerance ensures valid payments aren't rejected due to minor fluctuations.
Subscriptions
Model complex billing: free trials, promotional rates, graduated pricing. Each phase defines its own duration, price, and currency.
Transaction allocation
One crypto transaction can be allocated across multiple invoices: partial payments, overpayments, and multi-invoice splits.
Sandbox environments
Spin up multiple isolated sandboxes to test different configurations side by side. Create invoices, simulate payments, and verify behavior before going live.
x402 gateway
A hosted gateway that handles the x402 protocol for you. Configure an endpoint, share your gateway URL, and TRXN manages the 402 flow, settlement through your chosen facilitator, daily invoicing, and customer tracking. Zero protocol code required.
From the community
Built for developers, trusted by finance teams
Teams use TRXN to add on-chain payment verification without rebuilding their billing stack.
"We needed invoice-level verification, not just a wallet. TRXN checks the chain, matches the payment to the invoice, and handles the edge cases: slippage, partial payments, allocations. It just works."
