When I started Revoke in 2019, I never imagined it would become what it is today. 🔒 $125M+ protected from smart contract hacks 📈 200k+ monthly users 🌍 Millions of total users over the years 🏅 Top 20 most popular dApps (report by Blockaid) In the past five years it has grown from a small side project to one of the most-used security products in crypto, providing tools and education to millions. Join me on my journey in the crypto space as I share more insights into my experiences building security tools and educating users.

@honmashinsei Yes, the old sunsetted version of the Revoke extension is still available on GitHub and can be downloaded from there. However, the new extension has a lot more functionality and will be expanding even more in the future, so I definitely recommend using the new version.

@RoscoKalis can you confirm you dm'ed me with a manual github install . it sounds sketchy typing it even out so i'll hold off for now lol

@EthCC 👋

7 years ago today, March 6th 2019. EthCC[2] was a not-so-large conference. A rogue fire bell emptied the rooms and so we took the opportunity to snap a group photo. Back when the whole conference fit in one frame. Who do you spot? 👀🔔

Found myself in the picture. Looking forward to another EthCC this year, it's grown a bit since 2019 👀

That is what I'm realising as well. For a long time I thought public goods funding was going to be a sustainable revenue source for projects like these, but unfortunately grants alone aren't enough. That said, grants help, and I do hope to see more organizations pick up grants funding more actively.

@BelmaDzi @RevokeCash @RoscoKalis Grants are unfortunately not sustainable. Funding projects like revoke or even rotki is tbh still an open question.

Do I know anyone with heavy $GNO bags? If so can you guys vote in favor of supporting @RevokeCash in this proposal that @RoscoKalis made? These are tough times. Aligned apps like revoke need all the support they can get. 💪 snapshot.org/#/s:gnosis.eth…

@DefiIgnas @LefterisJP @RevokeCash Much appreciated sir 🫡

@LefterisJP @RevokeCash @RoscoKalis had voted for yes!

@LefterisJP @RevokeCash Thank you for the shoutout Lefteris! Though times indeed unfortunately. 🫡

@0xghooost @ensconnoisseur @blk_diamond__ @sat_eth @james_base_eth Yeah it was a previous owner, this happened some years ago.

@RoscoKalis @ensconnoisseur @blk_diamond__ @sat_eth @james_base_eth I’m the one who registered roscokalis.eth few days ago, and I never asked you for 30 ETH! Maybe you mean the pre owner who let the name to expire, and I never offered you my price yet 😅 You can DM me so we can settle on a deal 🫡

revoke.eth secured 🤝 Thanks @blk_diamond__, @sat_eth and @james_base_eth for bringing it to our attention that it was available once again. Now we continue building! 🚀

@ConorSvensson @blk_diamond__ @sat_eth @james_base_eth Revoke doesn't have its own contracts, so no naming needs to be done. But definitely agree contracts should be named!

@RoscoKalis @blk_diamond__ @sat_eth @james_base_eth Nice — time to get the revoke.eth contracts named? Contract naming season is still going.

@ensconnoisseur @blk_diamond__ @sat_eth @james_base_eth Yeah roscokalis.eth was registered by a scalper that asked me to pay 30 ETH for it 😅

@RoscoKalis @blk_diamond__ @sat_eth @james_base_eth Nevermind, I think this should be you :-)

@Steen3S @DanielLockyer What do you mean, my current system works tooootallyyy fiiinee 😅

@DanielLockyer Will try this today. @RoscoKalis maybe this works for you as well haha

Insane quality of life improvement

@OctantApp @arlery Love to see it @arlery!

Meet our new CMO, Mashal Waqar @arlery "Couldn't be more excited to bring our mission at Octant to life. This year, we're going from quiet to being loud and proud about everything we're working on. We've only shared a teeny part of it in the past. 2026, let's bring it on." A decade ago, she was writing articles in student-run print publications and organizing workshops to raise more awareness about decentralization and the power of Bitcoin. Since then, she's built three companies across media, D2C, and audience growth consulting. Her work has been featured in Forbes, BBC, CNN, GQ, and Entrepreneur, and she's been recognized by multiple governments for her contributions to media and entrepreneurship. In crypto, she co-authored the State of Web3 Grants reports, served on the @gitcoin Grants Council and @0xPolygon Community Treasury Board, and has spent the last two and a half years leading all things marketing at Octant.

@cryptoShields @wiimee @RevokeCash @OctantApp Come over to Amsterdam!

@wiimee @RevokeCash @OctantApp You head that @RoscoKalis 🤣

That concludes Octant Epoch 10. 2025 has been a tough year and the funding that we've just received is more than all other grants from the past 12 months combined. So a big thanks to Octant for continuing to lead the public goods funding drive even in harder times. Especially in harder times. 🫡

We're going live with @OctantApp now, join in for talks about privacy and security 👇 x.com/i/broadcasts/1…

2025 has been a really bad year in terms of public goods funding. The LAST significant funding Revoke had received was actually from Octant Epoch 6 in January 2025 - a full year ago. It's a testament of @OctantApp's dedication to the public goods cause that Epoch 10 will most likely be the first significant funding we'll receive in 12 months. We hope to see more organisations join Octant in this mission of Public Goods Funding.

@forgebitz And then it automatically creates a PR to update the footer I presume?

many people don't know this but the easiest way to update your footer date is to use a redis cache check if the yearly key has expired, and simply set the new date it's important that you start this service at midnight

@gregskril Yeah but the malicious delegations are basically all on compromised seed phrases so doesn't mean a whole lot

also wow there's a lot of malicious delegations 🥲 dune.com/wintermute_res…

erc7702 actually works really well in a happy path (app + wallet support it)! unfortunately that's not often the case common path is only 1 party supporting it, then the app dev getting complaints. this leads to app devs not wanting to implement it in the first place, which of course makes wallet devs think there's no demand for them to implement it, etc. cat and mouse game, yay my favorite and even if an app dev wanted to support both paths, its kinda tricky because wallet_getCapabilities support isn't great i think (could be wrong here, but either way its definitely a good amount of code to handle both flows)

What is the best replacement for Reservoir now that they're gone? Especially for their market data and metadata APIs? I know I'm late to this 🙈

@KhanAbbas201 That was quick decision making!

LASIK done ✅ After 8 years I can start being cool again.
