喵喵名单 is a simple Chrome browser extension that checks if the currently visited webpage is safe. It provides a whitelist service by displaying "SAFU" on the extension's icon for safe webpages, and it does not display anything for insecure or unknown webpages. However, it does not have the capability to detect malicious addresses.

This extension is particularly useful for Web3 users who frequently visit a few trusted websites and want to prevent accidental phishing attempts. It provides peace of mind by ensuring that users do not mistakenly enter the wrong website or click on suspicious links, especially when interacting with their wallets.
