Revoke

An anti-cheat tool that revokes Ethereum-authorized dapps that can spend your tokens at any time. Take back control by revoking authorization. Revoke.cash, a token balance and permission query protocol, released an open source browser plug-in based on Chromium. When a user interacts with a suspected phishing website, it can prompt the user to pay attention to authorization risks in the form of a pop-up window. This browser plug-in is applicable to any EVM-based chain Go online. The extension is currently available on Chrome, Brave, Edge, and other Chromium-based browsers through the Chrome Web Store, and support for other browsers such as Firefox or Safari may be added in the future.

Why You Should Use Revoke.cash?

1. Use Revoke.cash periodically.
It is always good to limit your approvals whenever you are not actively using a dapp, especially for NFT marketplaces. This reduces the risk of losing your funds to hacks or exploits and can also help mitigate the damage of phishing scams.
2. Use Revoke.cash after getting scammed.
Very often, scammers try to trick you into granting them an approval to your funds. Sort your approvals by most recent to find out which approvals are to blame and revoke them to prevent further damage. Unfortunately it is not possible to recover funds that have already been stolen.
3. Use the Revoke.cash browser extension.
Prevention is better than mitigation. The Revoke.cash browser extension warns you when you’re about to sign something potentially harmful. This can save you from phishing scams by making you think twice about what you’re doing.

Revoke.cash – web3 scam protection

The Revoke.cash browser extension helps protect you from common crypto scams.

In many cases, phishing websites try to make you sign a token allowance while they pretend to be an NFT mint or other legitimate use cases. When these phishing scams happen, it is recommended to use the Revoke.cash website to mitigate the damage, but it is even better to prevent the scam in the first place.

This is where the Revoke.cash Browser Extension comes in. The extension pops up whenever you are about to sign an allowance and will inform you of the allowance details. This can help prevent signing malicious allowances.

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 Revoke.cash browser extension does not interrupt your normal flow.

The different categories of warnings can be turned on and off in the extension settings.

The Revoke.cash browser extension works with every EVM-based chain including Ethereum, Polygon and Avalanche.
