What it doesUSDT Checker (
https://usdtchecker.app) is a web tool that verifies a wallet address across four chains — TRON, Ethereum, BNB Chain and Solana. It reports the balance, recent transaction history and a risk score, and flags addresses that appear on official sanctions lists with a red "Sanctioned address" badge.
Screening covers the U.S. OFAC SDN list, the Israel NBCTF list and the France asset-freezing list — 1,833 addresses at the time of writing. Solana transaction history is included.
Who it is for- Anyone receiving USDT who wants to confirm a payment is real before shipping goods or releasing funds.
- Marketplaces and p2p traders who want a fast sanity check on a counterparty's wallet.
- People who have already been burned by a "fake payment screenshot" and want to verify the next one properly.
Pricing (honest)- Free tier: 3 checks, no card required.
- Paid plans exist for higher volume; details are on the site. No subscription is required to run the free checks.
What it is NOT- It is not financial or legal advice.
- It does not guarantee a counterparty is trustworthy; it reports on-chain data and sanctions-list membership only.
- It does not claim to recover lost or stolen funds.
Why I'm postingThis started as an internal tool to stop a specific problem — fake USDT payment screenshots — and I'm sharing it because that problem is everywhere right now. Feedback is welcome; if something is wrong or unclear, tell me and I'll fix it.
Update log- 16 Oct 2026: launched sanctions screening (OFAC / Israel / France — 1,833 addresses), Solana history, crypto Pass plans.
