Last night, I was listening to an old song and heard the line "Don't leave the key on the door," and suddenly I remembered I used to do that too: once a contract was authorized, I would just check the "unlimited" option to save trouble, and I felt pretty secure about it... Honestly, it's similar to not revoking permissions before going to sleep—sure, you can sleep, but you always feel like the door isn't locked. Recently, cross-chain bridges have been hacked again, and oracles reported outrageous prices, and everyone is just "waiting for confirmation," which makes me even more afraid of that slow reaction—by the time something really happens, and you go to revoke, it's usually too late. There are many tutorials, but I prefer those that explain risk scenarios like accident reviews, so I can quickly clear out unused authorizations and avoid being woken up in the middle of the night by market noise.
