"Playing casually with a wallet loaded with Bitcoin $BTC on DApps? Perform an authorization check regularly" Many people, for convenience, often use the same Web3 wallet on their phone to both store large assets and connect to various decentralized exchanges, staking mining, and even claim airdrops. Every authorization you click on-chain is like planting a time bomb: 1. Risk of unlimited allowance authorization: Many DApps, to avoid multiple user signatures, request "unlimited token call permissions" by default. This means the smart contract can directly withdraw tokens from your wallet at any time in the future. 2. Project code vulnerabilities causing collateral damage: Even if the project authorized at the time is legitimate, if its smart contract is hacked six months later, the hacker can directly use the unlimited authorization from back then to drain all tokens you've authorized in your wallet. 3. Regularly clear authorization allowances: Use authoritative on-chain security tools to regularly check your wallet's active authorization list and completely clear or revoke allowances for idle projects. Prevent problems before they happen. Keeping addresses holding large funds in a "zero external authorization" state is the true top-level defense. $BTC $ETH
