Ever wish you could revoke multiple approvals in one transaction? Fewer clicks, same outcome? ๐ That day is finally here. Ethereum's Pectra upgrade just unlocked batch revoking - and Revoke already supports it.๐

Two security legends ๐
My first ever IRL meetup in Crypto was in 2022. That's where I met someone who constantly restores my faith in why I'm here (in this industry). We're talking about @RoscoKalis, the founder of @RevokeCash. Since 2019, he built and maintained one of the most used security tools

This new model will ensure that core security tools remain free for everyone, while allowing us to grow and keep building new features like the recently added History tab and Delegations tab. Thank you for your continued support โค๏ธ Read the full post here:

Some networks are stepping up to sponsor these fees for their users. @Optimism is the first network to do this. Users on Optimism can batch revoke for free, with costs covered by the Optimism Foundation. We hope that more networks follow Optimism's lead in the future!

Nothing changes for our core functionality: revoking approvals one by one will always remain free. But if you want to save time, using Batch Revoke will now come with a $1.50 fee per batch. This helps us cover infrastructure costs and fund continued development of new features.

For years, Revoke has been 100% free and open source, supported entirely by grants and donations. As the crypto ecosystem changed and public goods funding declined, this model became unsustainable. To keep building and protecting users, we need a sustainable model.

Since 2019, Revoke has helped millions of users stay safe, preventing over $140M in losses from smart contract hacks. We want to make sure we can continue to protect our users for the years to come. To be able to do that, we're introducing a small batch revoke fee. ๐งต๐

We can't change the blockchain history, but we can help you read it. ๐
Approval history used to be chaos. Consider it revoked. The new History tab on Revoke shows every approval and revoke you've ever made. Clean, simple and all in one place. ๐ฅ See it in action:

In the past I've always been very optimistic about building public goods in crypto. But this year it has been much harder to find grants and public goods funding. "Regular" companies have a clear advantage in that building a better product and making more money tend to go hand

โ ๏ธ dTrinity dLend exploit โ ๏ธ @dTRINITY_DeFi reported an exploit on part of their dLEND product. While it looks like most losses belong to the team itself, it is recommended to revoke approvals out of caution. See if you're affected below ๐ https://t.co/OVTtrlVxRC

Over $100k has been stolen in the 2025 dTrinity dLend Hack on 2025-09-28. Check if you're affected.

And make sure to check out our blog with details about the collaboration and more information on the importance of using Cold Storage https://t.co/RqdhA7gSPs
revoke.cash
It is important to use a cold wallet to store your crypto assets. To help users understand the importance of cold storage, we've partnered with Pudgy Penguins to create a Cold Storage SBT.

How to claim your Cold Storage SBT: 1. Visit https://t.co/V7qyMT1M5l 2. Enter your eligible wallet address 3. Pass the security quiz 4. The SBT will be sent to your wallet

Hot wallets are great for trading, but they leave you exposed to malware, phishing, and scams. A true cold wallet, secured with a hardware device and kept free of token approvals, is the safest way...

A Pudgy Penguin is best kept cold. In a hardware wallet WITHOUT any token approvals. Because using Cold Storage is paramount for security, @pudgypenguins and @RevokeCash are introducing the Cold Storage SBT to encourage users to take real steps towards better security ๐ซก
