Check a TON wallet

What the check covers on TON

A TON check reads the wallet's transfers and the counterparties behind them: sanctions designations, scam and phishing clusters, drainer wallets, gambling and no-KYC venues, mixing services, bridges, stolen-funds trails and mule networks. Where the wallet holds USDT — the jetton that carries most stablecoin value on this network — the check also reports issuer freeze status.

The verdict is CLEAN, LOW, MEDIUM, HIGH or CRITICAL, with a recommendation and the decision drivers named in words. TON's payment flow lives inside chat, where a counterparty is a username and an address in a message, so the practical value of a check is that it turns an anonymous handle into a documented decision before the transfer, not after.

Sanctions are checked against the public record: OFAC's definitions are in FAQ 559 and the blocking obligation on its virtual currency FAQ topic page.

Address format on TON

TON addresses come in two forms. The user-friendly form is base64url and 48 characters, starting UQ (non-bounceable, the normal shape for a personal wallet) or EQ (bounceable, used by contracts and by some services) — for example UQBawwHxs5B_T4W_2I2-VlDA2UkFysX--lluWslljTN_RLtF. The raw form looks like 0: followed by 64 hexadecimal characters and is the same account written differently.

The memo is the thing that costs people money on TON:

1. Most exchanges use one shared TON deposit address and identify you by a memo or comment. Sending without it leaves the funds credited to nobody.
2. A memo is not a password. Anyone can see it on chain; it identifies an account, it does not authorise anything.
3. A missing memo is usually recoverable through the venue's support with the transaction hash, but it is slow and some venues charge for it.
4. UQ and EQ forms of the same wallet are interchangeable for receiving; use whichever the deposit screen shows.

What gets frozen on TON

USDT on TON is issued by Tether, and the issuer's powers travel with the token. Tether's terms allow it to "freeze any Tether Tokens held by you" (Section 2) and, on suspected prohibited use, to freeze or confiscate tokens, "blacklist Digital Token Addresses" and report to the authorities (Section 8) — tether.to/en/legal. A blacklisted wallet keeps the balance on screen and cannot spend it.

Toncoin itself has no issuer and cannot be frozen on chain. The everyday obstacle is the exchange deposit review, which stops funds that arrive from an address the venue's controls flag — a different process with a different remedy, and the one that a check before the transfer avoids.

Before you send, after you receive

1. Check the address a chat counterparty gives you before you send anything. A username is not an identity, and the address is the part with a history.
2. Copy the memo exactly, from the deposit screen, every time.
3. Read the reason, not only the verdict — a distant hop through a large exchange is a different decision from a direct transfer out of a scam cluster.
4. If funds you received return HIGH or CRITICAL, keep them where they are and document the deal: who paid, for what, which transaction. Moving them onward does not detach the trail.
5. Answer a venue's request for information with that record, and check the next counterparty before you accept the payment.

Free check vs workspace

For a TON deal being negotiated in Telegram, the check belongs in the same app: the Telegram bot, three free a day. Venues crediting TON deposits automatically should call the API and review exceptions in the workspace.
