TRXN enables businesses to accept cryptocurrency payments while managing pricing in fiat currency (USD). This page explains the end-to-end payment flow from defining products to allocating received funds.

​
Payment flow

The cryptocurrency payment lifecycle consists of five stages:
1

Define products and prices

Account holders create products with fiat-denominated prices. Each price can optionally include a slippage margin to accommodate crypto price volatility during payment confirmation.
Product: "Pro Plan"
└── Price: $99.00/month (USD)
    └── Slippage margin: 2%
2

Generate invoices

Invoices are created either manually or automatically from subscriptions. Each invoice contains line items that reference products and prices, establishing the fiat amount owed.For recurring subscriptions, TRXN handles invoice generation automatically based on billing cycles and phase schedules.
3

Assign crypto addresses

Payment addresses are generated or assigned for customers. Each customer has a wallet that holds one or more crypto addresses. When a customer needs to pay an invoice, the system provides the appropriate address for the selected cryptocurrency.
Customer: Acme Corp
└── Wallet
    ├── BTC Address: bc1q...
    └── ETH Address: 0x...
4

Verify payments

TRXN queries the blockchain to find transactions sent to the assigned address within the expected time window. For each transaction found, the system looks up the historical crypto-to-fiat exchange rate at the exact moment of the transaction and calculates the fiat value.See Transaction verification for the full verification flow.
5

Allocate transactions

Verified transactions are allocated against outstanding invoices. A single transaction can be split across multiple invoices, and multiple transactions can be combined to satisfy a single invoice. The slippage margin determines how much price fluctuation is tolerated before a payment is considered complete.

​
Supported cryptocurrencies

TRXN currently supports:
  • BTC (Bitcoin)
  • ETH (Ethereum)
Each cryptocurrency uses blockchain-specific query providers and may have different price data sources.

​
How fiat and crypto work together

TRXN takes a fiat-first approach to pricing:
  1. Prices are always defined in fiat (USD). There is no need to set crypto-denominated prices that become stale as markets move.
  2. Conversion happens at verification time. When a blockchain transaction is detected, TRXN looks up the historical exchange rate at the moment of that transaction to determine the fiat value.
  3. Slippage margin absorbs volatility. A configurable tolerance percentage prevents invoices from being marked as underpaid due to minor price swings between payment initiation and confirmation.
