The Journey

Journey of Revoke Cash


  • Revoke.cash was initially created in October of 2019 by Rosco Kalis after attending Devcon 5 in Osaka, where he discussed token approvals with Paul Berg, the creator of the DeFi project Sablier. Initially, Rosco supported Revoke.cash as a side project while working for other crypto companies.
  • In 2021, Rosco added support for revoking NFT approvals, coinciding with the rapid rise of NFTs.
  • In early 2022, Revoke.cash was expanded to support multiple blockchain networks, eventually reaching over 40 supported networks to date.
  • In July 2022, Rosco developed Revoke.cash Browser Extension as a response to the increasing number of scams in the cryptocurrency space. Around the same time, he decided to dedicate himself full-time to Revoke.cash.
  • In early 2023, a comprehensive overhaul of the Revoke.cash website was released, resulting in improved flexibility for adding more features and enhancing the overall user experience.

What makes Revoke stand out?

While the underlying technology of Revoke.cash may not be groundbreaking, Rosco Kalis believes that the innovation lies in making its functionality accessible to the general public. When Revoke.cash was initially developed in 2019, some hackathon projects focused on approvals, but no established projects like Revoke.cash at that time.

Furthermore, when support for NFTs was added and later introduced multi-chain support, no other projects offered these features. Revoke.cash stood out as one of the pioneers in providing such functionalities. Similarly, with the creation of the browser extension, although there were existing extensions with similar capabilities, Revoke.cash became one of the earliest to support all EVM chains seamlessly.

Rosco's vision was to make managing approvals more accessible and user-friendly, which sets Revoke.cash apart as an innovative solution in the market.
