Revoke.cash primary-source snapshot
Fetched: 2026-04-25 UTC
1) Official homepage
Source: https://revoke.cash/
Selected excerpts from the official site:
When using dapps like Uniswap or OpenSea you have to grant them permission to spend your tokens and NFTs. This is called a token approval.
If you don’t revoke these approvals, the dapp can spend your tokens forever.
Take back control by revoking your approvals.
Additional signals from the homepage:
- The homepage is very clear about the core problem statement: lingering token approvals as an ongoing wallet-security risk
- Official FAQ copy on the site also emphasizes wallet hygiene, post-scam mitigation, and the distinction between disconnecting a wallet and actually revoking approvals
2) Official About page
Source: https://revoke.cash/about
Selected excerpts from the page:
Revoke.cash was created in 2019 by Rosco Kalis.
Today Revoke.cash is maintained and developed by Rosco and a small team of independent contractors and is funded by donations and grants.
We see Revoke.cash as a piece of essential web3 infrastructure, which is why our tools are open source and free to use.
Additional signals from the About page:
- The page is useful for understanding the project’s self-conception as independent security infrastructure rather than a tokenized protocol or venture-backed wallet product
- It also highlights expansion from a single approvals tool into a broader browser-extension and security-tooling surface
3) Official Learn section
Source: https://revoke.cash/learn
Selected excerpts from the page:
We created the Revoke.cash Learn section to help you understand how you can stay safe in the world of web3.
It covers the very basics of web3 and then moves on to more advanced topics.
What Are Token Approvals? … How to Revoke Token Approvals … What Are Permit Signatures? … What Is Permit2?
Additional signals from the Learn section:
- Revoke.cash is not only a dashboard; it also operates a substantial educational surface around wallet security, approvals, scams, and wallet mechanics
- This educational layer is part of the project’s real operational footprint and makes it more infrastructure-like than a simple one-page tool
4) Official GitHub organization and main application repository
Source: https://github.com/RevokeCash Source: https://github.com/RevokeCash/revoke.cash
Selected excerpts/signals from the public org and repo pages:
❌ Revoke or update your token approvals.
🛡 Protect yourself from crypto scams online.
revoke.cash allows you to inspect all the contracts you’ve approved to spend money on your behalf, and revoke their access for the ones you no longer need.
Additional signals from the org and repo:
- The GitHub organization shows multiple public repos spanning the main app, browser extension, approval-exploit lists, address-label data, and chain metadata
- The main app repo is unusually informative: it documents multichain support dependencies, how new chains are added, and the external RPC / block-explorer / indexer surfaces the product relies on
- This makes Revoke.cash easier to classify as production wallet-security infrastructure rather than purely consumer content
5) Official browser-extension repository
Source: https://github.com/RevokeCash/browser-extension
Selected excerpts from the repo:
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 Revoke.cash browser extension works with every EVM-based chain including Ethereum, Polygon, and Avalanche.
Additional signals from the repo:
- Even though this repository is marked as the legacy extension, it is still valuable primary evidence of Revoke.cash’s phishing-prevention/product direction beyond the approvals dashboard
- The extension helps distinguish Revoke.cash as an active wallet-safety stack, not merely a post-hoc revoke website
Notes
- This pass did not locate a classic whitepaper or litepaper.
- Revoke.cash appears best categorized as wallet security / token-approval management / phishing-prevention tooling.
- The strongest primary materials were the official site, About/Learn pages, and open-source repositories.
