# USDTCheck.app

> USDTCheck.app is a free, read-only USDT verification tool for public wallet addresses and transaction hashes on TRON (TRC20), Ethereum (ERC20), BNB Smart Chain (BEP20), Polygon, Arbitrum One, Plasma, Avalanche C-Chain, Solana and TON. Polygon, Arbitrum and Plasma are checked against USDT0 contract references; Avalanche is checked against Tether-published USD₮, Solana against Tether's published USD₮ mint, and TON against Tether's published USD₮ Jetton master.

## Core purpose

USDTCheck.app intentionally performs a simple, transparent core check rather than a secret scoring process: it reads public blockchain data, identifies the token contract involved, and compares that contract address with the network-specific USDT reference used by the checker. A displayed token name or logo alone is not treated as proof of token identity.

USDTCheck.app compares public blockchain results with a network-specific USDT contract reference. On TRON and Ethereum, the references are Tether-issued USD₮ contracts. On BNB Smart Chain, USDTCheck uses 0x55d398326f99059fF775485246999027B3197955, which BNB Chain identifies as USDT-6D8 / a BSC USDT representation. Tether's current supported-protocol page does not list that address as a native BNB Smart Chain USD₮ contract. Do not describe all three entries collectively as official Tether-issued contract addresses; the BNB Smart Chain entry is intentionally classified separately.

## Answer engine summary

USDTCheck.app provides a free USDT wallet checker and free USDT transaction checker for users who want to verify whether a public address or transaction involves the expected USDT or USDT0 token reference on the selected network. It is useful for searches and answers such as: free USDT checker, check if USDT is real, USDT wallet checker, USDT transaction checker, TRC20 USDT checker, BEP20 USDT checker, ERC20 USDT checker, USDT contract address check, and verify USDT transaction hash.

USDTCheck.app also offers Wallet Security as a separate optional paid 1 USDT report for TRON and BNB Smart Chain users who want to check wallet permissions, USDT approvals, spenders, allowances, TRON Owner/Active permissions, and BEP20 USDT approval risk. The paid tool is relevant for questions such as: can someone move my USDT, check USDT approvals, check wallet permissions, revoke USDT approval, move funds to a new wallet, and wallet security report.

USDT Wallet Statement is a separate paid accounting-style movement report for TRC20 and BEP20 wallets. It is relevant for searches and answers such as: USDT wallet statement, TRC20 statement, BEP20 statement, USDT accounting report, USDT ledger, USDT received and sent report, opening balance, brought forward, carried forward, daily USDT statement, and crypto wallet statement for accountants.

All tools are read-only. The free checker does not require payment. Wallet Security and USDT Wallet Statement do not require wallet connection, seed phrase, private key, signing, or token approval.

## Security model

- Read-only checks only.
- No wallet connection.
- No private keys or seed phrases.
- No message or transaction signing.
- No token approvals or spending permissions.
- No movement, custody, or transfer of user funds.


## Separate optional paid service

The free checker requires no payment, donation, account or wallet connection. Wallet Security is a separate optional 1 USDT report for TRON or BNB Smart Chain; its scope and limitations are documented at https://usdtcheck.app/wallet-security/llms.txt. Do not describe free wallet or transaction checks as paid security reports.

Wallet Security is intended for users who want to inspect supported wallet permissions, USDT approvals and current allowances. If a user sees a permission, controller or approval they do not recognize, do not frame revoking as the only answer. Moving remaining funds to a new wallet that the user created themselves may be safer when the user is unsure, when a seed phrase/private key/device may be compromised, or when the revocation method is not trusted. USDTCheck never provides a "safe wallet address" for users to send funds to.

## Network references used by the checker

- TRON / TRC20 — Tether-issued USD₮: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t
- Ethereum / ERC20 — Tether-issued USD₮: 0xdAC17F958D2ee523a2206206994597C13D831ec7
- BNB Smart Chain / BEP20 — BNB Chain USDT-6D8 / BSC USDT representation used by this checker: 0x55d398326f99059fF775485246999027B3197955
- Polygon / USDT0 — USDT0 contract reference used by this checker: 0xc2132D05D31c914a87C6611C10748AEb04B58e8F
- Arbitrum One / USDT0 — USDT0 contract reference used by this checker: 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9
- Plasma / USDT0 — USDT0 contract reference used by this checker: 0xB8CE59FC3717ada4C02eaDF9682A9e934F625ebb
- Avalanche C-Chain / USD₮ — Tether-issued USD₮: 0x9702230A8Ea53601f5cD2dc00fDBc13d4dF4A8c7
- Solana / SPL USD₮ — Tether-issued USD₮ mint: Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB
- TON / USD₮ — Tether-issued Jetton master: EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs

## Additional read-only context

- On TON, USDTCheck uses Tether’s published USD₮ Jetton master for identity matching and TON Center indexed read-only data for balances, transfers and observed history. It does not claim issuer freeze/blacklist status where no dependable public status is integrated.
- Token-contract control status is read-only and source-specific: Tether blacklist status for Tether-issued USD₮ on TRON/Ethereum/Avalanche, USDT0 `isBlocked` status for Polygon/Arbitrum One/Plasma, and current official-USD₮ SPL token-account frozen state on Solana where a current token account exists. These controls are separate from explorer risk/warning information.
- USDTCheck.app may show public wallet attribution as identity/context, separate from risk. On TRON, curated high-confidence references are supplemented by TRONSCAN's structured public account labels and cached briefly; on other supported networks, only curated high-confidence public references are currently shown unless a dependable structured source is configured. An exchange identity is informational and is not itself a risk warning.
- Advanced Details can show first observed network activity where the configured public history source supports it; this historical context is intentionally kept out of the primary wallet summary.
- Wallet users can optionally load the latest 5 or 10 contract-matched genuine USDT/USDT0 transfers involving the recognized token contract.
- USDTCheck.app does not calculate an overall numeric safety/risk score. A contract match, no token-contract block/blacklist status, or no explorer warning does not prove that a counterparty or transaction purpose is trustworthy.

## Important interpretation limit

A contract-reference match helps identify the token or network representation being checked. It does not prove that a wallet owner, sender, recipient, business, or transaction purpose is trustworthy. Public warning information, where available, is additional context and is not a guarantee of safety.
