About Us
Revoke.cash Created
Inspired by Paul Berg's talk at Devcon 5, Rosco Kalis builds the first token approval management tool, giving users a way to revoke unlimited approvals.
NFT Approval Support
As NFTs rise in popularity, many users are giving approvals to marketplaces like OpenSea. Revoke.cash becomes the first tool to support revoking NFT approvals, expanding beyond ERC20 tokens.
Multichain Expansion
The EVM ecosystem is growing rapidly, and Revoke.cash expands beyond Ethereum to support dozens of EVM-compatible networks.
Browser Extension Launch
The crypto ecosystem sees a large increase in scams and phishing attacks. Rosco releases a browser extension that warns users before signing risky approvals, providing proactive protection.
Going Full-Time
After leaving his previous startup, Rosco decides to focus on Revoke.cash full-time, turning it from a side project into a mission.
Website Redesign
At this point, Revoke.cash has had the same visual design since 2019. To pave the way for the future, a complete visual overhaul of the Revoke.cash dashboard and website is released.
Learn Section
While tools are an important part of security, it does not replace the need for education. A Learn Section is added to help users understand wallet security.
Team Growth & RetroPGF
Optimism RetroPGF provides major funding, enabling the first team expansion. In 2024, the team grows to include Dries and WiiMee as part-time team members.
Batch Revoking
A much-requested feature, users can now revoke multiple approvals in a single flow with queued transactions.
Single-Transaction Batch Revoke
EIP7702 enables revoking multiple approvals in a single transaction, massively improving the user experience of batch revoking.
Delegations & History Tabs
Revoke.cash expands beyond approval management with new tabs for managing delegations and viewing approval history.
Extension Overhaul
The threat landscape is constantly evolving, and the browser extension needs to stay ahead. Revoke.cash partners with Fairside to build a new extension with improved detection, UX and risk coverage.
Revoke Premium
With a decline in public goods funding, Revoke.cash needs to find a sustainable business model. Revoke Premium is launched to generate real revenue.
