pending payments, RBF

Each term in this glossary maps to one of these three points.

Three ideas explain most of the scams on this site.

If you learn only three terms from this page, make them seed phrase, contract address and finality. Almost every scam described on this site attacks one of them: it steals the phrase, fakes the token, or asks you to act before the payment is final.

What is the transaction hash, and where do you find it?

The transaction hash is a unique ID for one transaction on a blockchain. It is a long string of letters and numbers. You can paste it into the explorer for that network to see the full record: sender, receiver, token, amount and status.

Where you are	Where the hash is shown
Trust Wallet, MetaMask, TronLink	Open the transaction in history, then “view on explorer” or “transaction ID”
Exchange withdrawal	Withdrawal history, usually as “TxID”
Exchange deposit	Deposit history, next to the amount
Explorer	At the top of the transaction page

A hash is only useful if you check it yourself. See fake transaction IDs.

Contract address meaning, in plain words

A contract address is the location of a token’s code on a blockchain. Every token on TRON, Ethereum and BNB Chain has one. The contract address meaning for you is simple: it is the only reliable name of a token. Names and logos can be copied, the contract cannot. See USDT contract address.
