increaseApproval TRC20
Some TRC20 tokens expose increaseApproval / decreaseApproval alongside approve. Learn how they change remaining allowance and how revoke still works.
Why some tokens add increaseApproval
Classic approve(spender, amount) sets the slot absolutely. increaseApproval adds to the current remaining; decreaseApproval subtracts. Tokens copy Ethereum-era patterns so UIs can bump caps without race-prone set-to-zero flows.
On TRON TRC20 the names may appear in explorers even when the wallet button still says Approve.
What you see on this desk
We show remaining allowance after whatever methods last wrote the slot. We do not label which method created it. Unlimited still means the max-uint pattern in remaining.
Listing does not call increaseApproval for you.
Revoke still means zero remaining
Whether the last write was approve or increaseApproval, clearing the spender means a signed transaction that leaves remaining at 0 — often approve(spender, 0) or a decrease that finishes the job.
Fake sites that say “increaseApproval unlock” and ask for a seed are theft.
Security note on race myths
Old Ethereum lore about approve races is not a reason to paste a seed into a helper DApp. Use your wallet’s revoke UI. Re-check on this desk afterward.
