@_julianma Thank you for your service 🫡🫡🫡

Life Update: I have decided to leave the Ethereum Foundation. I’m very grateful to have worked with so many talented and inspiring people on an incredibly important project over the past four years. I’m proud of the work we’ve done. Here are some of my personal highlights: - FOCIL. It will likely be the first multiple-proposer gadget live on any major chain. In a world where everything is financialized, my job was to prevent these proposer seats from being traded. - Fast Confirmation Rule Go-To-Market. Designed and led the GTM strategy for FCR. A new consensus rule that drops bridging time from Ethereum L1 to L2s and exchanges down to 13 seconds. - Strategy. Argued which markets Ethereum should go for and how. Trying to bring protocol design and ecosystem development closer to each other. Why did I leave? The first three years at the EF I did market design research. The last year, I focused on product and growth work (the FCR GTM and strategic work). I really enjoy that domain and want to move further in that direction. I’m taking some time to explore ideas that build on the financial infrastructure that crypto has built. I would love to catch up with friends made along the way. My DMs are open 🙂

Excited to welcome Archetype and Circle Ventures as strategic investors, with continued support from our long-term backers. The next generation of finance will be programmable. Software, agents, and onchain systems will move value globally at machine speed, and they’ll need infrastructure built for verifiable execution and programmable control. That’s the future we’re building for at Turnkey: scalable, API-first wallets and verifiable computing infrastructure designed for a world of programmable money and agent-driven transactions. Grateful for the continued conviction from Sequoia, Bain Capital Crypto, Lightspeed Faction, Galaxy Ventures, and Variant. Thank you to our customers for the trust you put in us, and a huge shoutout to the Turnkey team for grinding against this vision.

@0xrajath @Polymarket Incredibly hyped 😎😎😎

Excited to announce that I’m now leading Protocol Engineering @Polymarket ! I’ve been here about 3 months now and the engineering talent we’ve acquired over the past couple of months is insane. We have elite talent from some of the top crypto protocols and companies with years of crypto infrastructure experience under their belt, and we’re all starting to get into the rhythm of working together. You can see the result of it over some of the releases we had over the past few weeks. And we’re only getting started! Our mission is to will the promise of prediction markets into existence. And to achieve that we’ve oriented the Protocol team around the philosophy of ‘Product-led Protocol Engineering’. We do not build protocols because it’s intellectually stimulating, rather we build it because there’s a genuine problem to be solved. We ship with speed while being security conscious at the same time. If this excites you and you want to be working with me, @devjoshstevens and @shayne_coplan on a regular basis. Then reach out! We’re opportunistically looking for 1-2 more protocol engineers to join the team. Great engineering and design is table stakes. We’re additionally looking for high agency, good communication, great taste and customer intuition. You can be a superstar, but you’re still part of the team. We have an ambitious roadmap and aim to make Polymarket synonymous with Prediction Markets. We are the search engine for the future.

@justinmujin @firstc0in @grok How much is it worth for youtube+ the creators to do neobank stuff, include how much would be made in treasury yield on the float.

@bcog55 @firstc0in stablecoin payouts are great just doubt this YT neobank stuff is worth their time Btw you do not need a company to payout However most creators won’t matter in 3 years anyway

@justinmujin @firstc0in "I don't want to keep it there", in reality a lot of ppl just kinda leave money in these accounts before withdrawing/ their countries banking system isn't good and don't want to deal with FX I.e. It costs $20k USD to start a company in Switzerland reddit.com/r/askswitzerla…

@firstc0in if $ was deeply central to the platform's social graph and a feeling that the platform doesnt dictate if/when i get paid still would run relevant payroll and most personal spending off it (until can beat benefits of top credit cards + yield protocols/products)

@bfriel_ @phantom @BChillman @fragosti Thank you for your service 🫡🫡🫡🫡

Today is my last day at @phantom. I joined 4 years ago when we sat in the Solana office, and leave as the #1 wallet. Phantom is the best team in crypto, leading the fight for self-custody. I’m so grateful to @BChillman, @fragosti, and CK for letting me be a part of the journey.

@awxjack @_Arrayah 🥰🥰

@ky__zo 4 sure

starting an underground SF Monopoly Deal club (for all of us that can't play poker) reply if you want access, limited spots

@Jason I'm in

We started an AI founder twitter group... reply with "I'm in" if you're a founder and want to be added

@timahhl Foreign money transfers are the biggest crypto origin story

nothing radicalizes you on stablecoins faster than sending a canadian bank wire

@defyneric If you're a human and don't have a crypto card yet why?

if you’re a crypto company and don’t have a crypto card integrate yet why?

@cateland @colossuspay will remove a bunch of layers/ fees for this

Every stablecoin wallet wants a card. Almost none of them understand what that actually takes.

@DennisonBertram @Figure Would be worth looking at :)

@yawnxyz FIRE !!! I tried it at GTC How much better vs a mac mini day to day?

this thing has been doing some amazing things!!

@DennisonBertram Hedonic treadmill is wild, we should be impressed xD I For multistep processes, having more powerful and accurate models means fewer steps needed and less inaccuracies from the agent (as inaccuracies compound) It's harder to feel the impact with less iterations like before :/

@navaai @polychain Congratulations 🎉🎉🎉

AI agents are starting to move real money. The problem: there’s still no independent check between what an agent intends to do and what actually gets executed. Today, that changes. We're Nava, and today we’re coming out of stealth with an $8.3M seed round from @polychain, @archetypevc, @hack_vc, @FalconXGlobal, and @seedclub / @seedclubvc to build the trust infrastructure the agent economy is missing.

@zkBri 🥰🥰🥰🥰🥰

I’m incredibly proud to share that we’ve officially come out of stealth with a successful fundraise. This moment is about far more than capital, it’s the official launch of our mission to build the essential safety infrastructure for the agentic economy. For too long, autonomous AI agents have operated in a dangerous gray zone: powerful creativity with no reliable guardrails when real economic value is at stake. Today, we change that. Nava’s Arbiter provides rigorous, verifiable verification, ensuring every agent proposal is checked for intent alignment, safety, correctness, and adversarial risks before any capital moves onchain. No more black boxes. No more “trust me, bro.” Just transparent, accountable execution. With this funding, we’re accelerating from early demos to production-grade infrastructure that institutions and builders can actually trust. We’re moving beyond experimental DeFi agents toward a future of safe, scalable, institutional-grade autonomous finance. The agentic economy is no longer coming, it’s here. Our job is to make sure it’s built on a foundation of verifiable safety from day one. Huge thanks to our investors for believing in this vision. To the builders and institutions out there: the private testnet waitlist is open. Let’s build the trusted layer for autonomous agents, together. The best is yet to come. 🐦‍🔥
