Why Pre-Sign Protection Matters

[cryptoenthusiast]

️ Blockchains follow instructions exactly, which means once you sign a malicious permit, the attacker can act instantly.

The solution? Pre-sign tools that:

Simulate what a signature actually allows

Flag risky approvals and suspicious contracts

Screen against known drainer infrastructure

Web3 Antivirus is one tool doing this. It works like a co-pilot for your wallet, showing plain-language consequences before you hit Sign.

Tip: Always check who can spend your tokens, which tokens, and how much they can move — especially on gas-free permits.
