This @modretro Chromatic really made me smile, @PalmerLuckey. Thanks for making these on the side. Brought me back big time!

Vanguard CEO on Bitcoin ETFs in 2024: "We'll never offer Bitcoin ETFs, we're not going to change our mind around this". 2025: that person isn't CEO anymore. Bitcoin ETF trading starts tomorrow.

JUST IN: Vanguard CEO says they will not offer spot #Bitcoin ETFs because "it does not belong in a long-term portfolio" and it's "not a store of value."



This hit job by the @nytimes on @DavidSacks couldn’t be more misguided. We should celebrate competent people with real world and business experience spending their precious time serving American interests and the American people instead of inventing nonsensical BS because your…


A good reminder.

Happy Thanksgiving 🇺🇸🦃! Grateful for family, friends, and the opportunity to build meaningful things with an amazing team!


Important Op Ed by @seanrad in today’s @washingtonpost. The internet made the world smaller and that’s mostly great, but we have to mitigate foreign influence in domestic matters before it’s too late.

X’s great unmasking of account location is a monumental step toward online transparency. And it reminds us that in a borderless online world, digital borders matter.

Remember when LLMs didn’t have internet access?


California dreaming.

You ask, we deliver (collectively). More privacy features live on @spark.

We released an update to the @spark implementation of the Breez SDK: private mode is now enabled by default to provide stronger privacy for those who rely on bitcoin to move value. Thank you @HRF for sharing 🙏

.@peterthiel said startups should strive to build monopolies. We’ve now crossed into a new era — individual companies becoming macro events. @nvidia earnings today are more anticipated than a Fed rate decision. Wild times.


I love that in-person @walletofsatoshi payment experience so much. It's such a satisfying UX.

Wallet of Satoshi keeps getting faster ⚡️ In our 3.2.0 update we’re using our leaf optimization work (huge thanks to the @spark team). • Payments between self-custody wallets now average just 1.4 seconds! • Payments to Lightning invoices are now 31% faster • We’ve cut timing…



I really don’t enjoy building in hype cycles. I much prefer long stretches of focused work away from the noise.


Credit where credit is due, @jackmallers is 💯 the inventor of fiat ➔ ₿ ➔ fiat. He saw that before anyone else did. Without that insight @umastandard wouldn’t exist today.

In December of 2019, I actually texted @milessuter that I had an idea about moving currencies over Lightning and using Bitcoin rails inside Cash App. He asked if I could put a document together and present it to his team. I did. Their roadmap was full, so they suggested I apply…

Weekend quest… Experimenting sending $ from a US bank to @CashApp using UMA + @lightspark Grid. Very little work left to make this fully native within Cash App to enable sending and receiving to/from 65+ countries. Open networks FTW! Hat tip to Cash App team.

This is so great. Reminder that any @spark enabled wallet is compatible out of the box! The power of an open network in full display.

This feature will start to roll out tomorrow, allowing you to pay from @CashApp over bitcoin rails using your USD balance - no bitcoin required. This dramatically opens up the aperture of who can pay with bitcoin to our entire monthly user base of 58m - normies included.

Can't recommend reading 1929 by @andrewrsorkin enough. No one told the story of one of the most consequential crash in history from the angle of the main protagonists before. Fascinating read.

The cheat code with @Square isn’t paying with Bitcoin, it’s paying on Bitcoin. Over 4 million merchants can now get paid instantly from anywhere onchain, with everything settled on the motherchain.
