1/ It’s time for us to go public so you all can go private, and it’s time for us to be bold so you all can be safe. As part of our work with the @ethereumfndn, @VitalikButerin and I are proud to be the faces of Kohaku. 🧵👇

Introducing TamaSwap, the first provably unhackable DEX. - No-free-lunch theorem, machine-checked via Lean - Onchain HTML interface, forever online - No protocol fees, no-code deploy to any EVM chain Built with Tama Verity. AGPL license. The platonic ideal of xy=k.

this is fantastic! SafeLens brings offline ERC-7730 clear signing to Safe. No more blind signing risks on important txs. Fully offline and local. Builders like you make the ecosystem stronger! @Th0rgal_

LFG Labs received a grant from the @ethereumfndn to build Verity. Verity is a formally verified smart contract compiler written in Lean 4 🧵

We just released the EF Mandate. The blog expresses our message more fully, but at heart, we started working on this some time ago because Ethereum’s future no longer feels far away. It is already here. And with that comes a deeper responsibility for us: to be clearer about what we are here to protect, and how we must steward Ethereum’s promise. blog.ethereum.org/2026/03/13… We did not word the Mandate lightly. We honed in on each principle carefully, and deliberately chose every single word. This is our strong commitment, for all of EF, including the board. The principles we listed on the Mandate are not new or a big turn, these are what have been cultivated deep in our technology and our culture for a long time. However there were times we were too implicit about them. We are stating it clearly: that the principles of CROPS are something our members should always prioritize and because we believe that is the only way Ethereum can achieve complete success. The Mandate is not only a constitution, manifesto, and work guideline. For me, it is also a kind of love letter to Ethereum, and to everyone who cares about what it truly makes possible: a digital world that remains open, private, and secure, and gives us a new form of freedom to grow into. And this is not just ours. This is not an obligation to teams outside of EF by any means, but it is for anyone to freely adopt if relevant. Also if anyone feels this resonates, it means you are a fellow steward of the garden and we look forward to working with you 🌱 Special thanks to @pcaversaccio @_Enoch @LefterisJP @mashbean and others who gave us valuable feedback and advice! And to @tomosaito and to @shiro57102 for the beautiful art 🤍 ! EF Mandate : ethereum.foundation/ef-manda…

Talking with @ncsgy about formal verification, rust, AI and ethereum roadmap. We bumped each other into our coffee Fruto. Nico is one of the most trustworthy and authentic people in our industry. It’s always a pleasure to talk with him, he is like Lambda. He is involved in multiple different projects and he has interesting opinions that are always backed by technical arguments.

Gave several talks at @EFDevcon. But the one I enjoyed most was this one with @polymutex at the @ethinteroplayer day. If we had more contributors like @polymutex we'd be opening ethereum hubs on Mars already. Come help us @walletbeat needs you ! Looking for contributooors

Wonderland is a great team and has been very helpful in the Ethereum ecosystem, including to the EF on interop and Kohaku, and to many Ethereum projects.

Thanks for having me @0xprivacypools always a pleasure to see you ❤. Next stop @EthCC 👋

more from day 5 🇦🇷 @ncsgy from the @ethereumfndn presented Kohaku on the main stage, a wallet SDK and reference browser extension with native privacy pools support thank you Nico, @kassandraETH, @VitalikButerin, and everyone else working towards this inspiring vision

The Kohaku guide from the people building it at @wonderland First things first: congrats to @VitalikButerin , @ncsgy , and @kassandraETH for yesterday’s demo. I already told you privately, but it deserves a public shoutout. Kohaku enables a one-click private ethereum experience. The wallet is where users actually experience Ethereum. It’s where privacy either works seamlessly or doesn’t exist at all. To kick things off, here’s the Kohaku Handbook: the ultimate guide to privacy in wallets. ef.handbook.wonderland.xyz/

Been a busy day today... Welcome to Devconnect!

Introducting: The Lab We've rebuilt our Ethereum network visualization tool from scratch to make verifying networks simple and accessible. Featuring: - Modern design - Curated data views that can't be found elsewhere 🧵 1/5

It's time to be private on a public blockchain. Hinkal's Wallet is now open to everyone. Shield your wallet’s assets, actions, and dApp interactions from the public view. It's time to use crypto with confidence.

The Fusaka upgrade also introduces Verkle trees, a new data structure that significantly reduces the size of proofs needed to verify network state.

With Kohaku this is coming to an end. Time to change the broken app model and blow up the vendor locks ! We will do all the top DeFi protocol by TVL. It will take us a few months to cover 90% of ethereum's DeFi. Thanks to @BTChip @zknoxhq notes.ethereum.org/@niard/Ko…
