Stablecoin transaction receipt

What the record shows

A stablecoin payment leaves its facts on a public blockchain, but a bank or an accountant won't read a block explorer for you. The record puts them on one page, each with where it came from:

• The transfer. Network, token and its contract, amount, sending and receiving addresses, and a link to a block explorer to check it.
• When, and how final. The block time in UTC, the block (on Solana, the slot), and whether the network treats the block as final, with its confirmations.
• What it was worth. Its value in US dollars, euros and pounds at the block time, with the price it used.
• Freeze status. Whether Tether or Circle has frozen either address, checked when you make the record.

It reads only USDT and USDC at the contracts their issuers publish, on the networks Align accepts them on. A token with the same name at another address isn't USDT or USDC, and the record says so. Before accepting payments like this, see how to accept USDT and USDC from business customers, and check an address you've been given with the wallet address checker.

Every record ends with this line:

A record of public on-chain data and market prices, made by Align's free tool. Not a compliance check, an audit, an AML or sanctions screening, or a confirmation by Align. Banks and accountants may ask for more.

How the value is worked out

The record takes Kraken's public price candles for the token against the US dollar, the euro and the pound, finds the candle that contains the block time, and multiplies the amount by its closing price. It uses hourly candles while Kraken still publishes them for that hour, which is about the last 30 days, and daily candles for older transactions, up to about two years. It names the pair, the candle and the price, so the figure can be checked.

If no candle can be read, the record shows no value rather than an estimate. For a transaction in the current hour, the candle hasn't closed yet, so the record uses the latest trade and says so. USDT and USDC trade close to one dollar, so the dollar value is usually within a fraction of a percent of the amount; the euro and pound values follow the exchange rate.

Freeze status

Tether and Circle can freeze their tokens at an address. Tether's terms (last updated 26 February 2026) let it freeze tokens "as required by applicable Law or where Tether, in its sole discretion, determines it is prudent to do so", and since December 2023 it has frozen wallets on the US sanctions list. Circle's access denial policy says a blocked address "can no longer send or receive" USDC. The record checks both parties when you make it, and prints the time of the check:

• USDT on Ethereum and Tron: the blacklist in Tether's contract (its isBlackListed function).
• USDC on Ethereum, Base, Arbitrum, Polygon, Optimism and Avalanche: the blacklist in Circle's contract (isBlacklisted).
• Solana: whether each party's token account for USDT or USDC is frozen.
• USDT on Polygon, Arbitrum and Optimism isn't checked, and the record says so.

"Not frozen" means only that the issuer hadn't frozen the address at that moment. It isn't a screening: an address can be linked to a scam or a sanctioned party without being frozen. Why issuers freeze, and how a business avoids it, is in why USDT and USDC get frozen.

The details banks ask for

The FATF's travel rule applies its Recommendation 16 to virtual assets: exchanges and other crypto providers must obtain and hold the sender's and the recipient's information, and pass it on with a transfer. The FATF's guidance lists the sender's and recipient's names and their account numbers, which for crypto can mean wallet addresses, plus the sender's address, an identity number or date of birth (FATF Recommendations as updated October 2025, and guidance of October 2021; checked 13 November 2026). A blockchain transfer carries only the addresses. So when funds that arrived as a stablecoin reach a bank or an exchange, it may ask you for the names. It may also ask what a payment was for and which invoice it settles, though that isn't part of the travel rule.

The optional fields add those to the record: your company's name, the other party's name, the invoice or reference, and the purpose of the payment. They stay in your browser, are printed as you type them, and are marked on the record as your own statement. Whether the travel rule applies to your company depends on your role and your country; see the crypto travel rule for stablecoin payments.
