A connection is not a spending permission
Connecting a wallet can reveal a public address to a website. A separate approval may let a contract spend particular tokens. Treat each request as its own decision rather than assuming that an earlier connection made everything safe.
Check the spender and the amount
Read the requested token, spender, network and allowance. A very large allowance can authorize more than one intended interaction. A familiar website design does not establish that the contract requesting permission is legitimate.
Be cautious with unexpected claims
Unsolicited tokens and airdrop links can lead to approval requests. A token appearing in your wallet does not mean you must interact with it. Avoid following claim instructions from an unfamiliar sender.
Review permissions through trusted tools
Use guidance from your wallet provider and independently verified tools to inspect existing permissions. Revoking an allowance changes future access; it does not reverse completed transfers or replace securing a compromised recovery phrase.
