Allowance
Allowance is the remaining amount a TRC20 spender may pull with transferFrom. Separate from wallet balance and from energy.
Definition
Allowance is the numeric remaining permission stored as allowance(owner, spender) on a TRC20 token contract. It falls when a capped spender pulls, and it stays huge when set to max uint256.
It is not your token balance. It is not EnergyLimit.
How it appears on-chain
Written by approve, and on some tokens by increaseApproval / decreaseApproval. Read by routers before transferFrom. Explorers and TronScan approve/list expose the remaining figure this desk prints.
A zero remaining means that spender should not be able to pull further.
How this checker shows it
The remaining column plus an unlimited mark when the value is the max-uint sentinel. Filters help you ignore dust caps.
We do not change allowance.
Common confusion
People think sending USDT clears allowances. It does not. People think closing TronLink clears them. It does not. People look for leftover energy on this page — wrong desk.

Related mechanics
approve sets it. Spender uses it. Revoke zeros it. Unlimited is a special remaining value. Independent desk. @wholetron. Never a seed.
