Odaily News Yu Xian, the founder of SlowMist, said in a post that the current Ethereum Gas fee is at an extremely low level, and the cost of canceling a single token authorization is only about $0.01. Users should seize the current window and cancel all "uncertain/unclear/self-perceived safe" authorizations through tools such as RevokeCash and Rabby. Even if hundreds of authorizations are processed in batches, it only costs a few dollars, but it can effectively block potential high risk exposure.
