approve()
approve() is the TRC20 method that sets a spender’s allowance. It does not transfer tokens; transferFrom does.
Definition
approve(spender, amount) is the standard TRC20 call that writes allowance(owner, spender). Amount may be a cap or max uint256. The owner signs; tokens stay in the wallet.
It is permission, not a send.
How it appears on-chain
A transaction to the token contract (for USDT: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t) with method approve. Wallet UIs may say “Approve USDT” or similar.
Later transferFrom is a different transaction.
How this checker shows it
We do not list historical approve txs one-by-one; we list the resulting live remaining allowances via TronScan approve/list.
We do not send approve.
Common confusion
“I only approved” still grants pulls. Closing the DApp does not undo approve. Seed phrases are not part of approve.
increaseApproval is a sibling method on some tokens.
