The browser extension helps protect you from common crypto scams.

In many cases, phishing websites try to make you sign a token approval while they pretend to be an NFT mint or other legitimate use cases. When these phishing scams happen, it is recommended to use to mitigate the damage, but it is even better to prevent the scam in the first place. This is where the Browser Extension comes in. The extension pops up whenever you are about to sign an approval and will inform you of the approval details. This can help you prevent signing malicious approvals. The extension also informs you when you are about to list an item for sale on popular marketplaces such as OpenSea and LooksRare, or when you are about to sign a hash. These hashes are used by certain marketplaces like X2Y2 for listing NFTs. A common scam is to try to trick you into signing one of these gasless signatures on a phishing website, allowing the scammers to steal your NFTs. The official websites of OpenSea, LooksRare, X2Y2, Uniswap and Blur are allowlisted for these actions, so that the browser extension does not interrupt your normal flow. The different categories of warnings can be turned on and off in the extension settings. The browser extension works with every EVM-based network including Ethereum, Polygon and Avalanche.

Hey, it's possible that this phishing website uses different scam methods, such as direct ETH transfers. We only provide warnings for specific methods, such as token approvals and NFT listings. By using this approach, we can easily support *every* EVM chain out of the box, but we don't cover 100% of the cases. Usually cases like direct ETH transfers are also easier to see and in your main wallet extension. If you want an extension that shows information / explanations for *every* transaction, then Wallet Guard or Pocket Universe can be good alternatives, but these options only support a few of the big EVM chains. Feel free to join the Revoke Discord if you have any more questions!

Hey, thank you for the positive review! Regarding your comment, we're generally very confident about our ability to detect active approvals, and often when our users think there are missing token approvals, this is because some approvals get automatically revoked. Check out our Twitter thread for more information about this: If you do believe you found a missing token approval, please reach out on our Discord or Twitter (links in our website footer), so we can look into it in more detail.
