Regarding the issue of some users' USDT being authorized without limits in the Binance web3 wallet this morning!
Here are some suggestions:
1. Do not immediately click to revoke authorization; this may be a scam or a hacker trying to maliciously extract miner fees. Some users have reported that they still couldn't revoke it after clicking, and the fees for the second attempt might be even higher! So it is advised not to click to revoke authorization for the time being!
2. It is recommended to immediately transfer the assets from the web3 wallet back to the Binance exchange.
3. If you have participated in airdrop benefits recently, you can temporarily keep the wallet and delete it after the rewards are realized!
4. Personally, I suggest not using this wallet anymore, and creating a new wallet for future airdrop activities!
