Witness the Manhattan Project of gas turbines.
Major congratulations to @CarlSchoeller and the team.
Carl is a MechE prodigy and the right man to get this job done. There will be millions of turbines!
Today we’re launching Parallax, the AI energy company with a $117m fundraise led by Founders Fund, Eclipse, Lux, Diffusion, Greylock and General Catalyst. (1/5)

I see a lot of talk about how AI will make custom hardware more tenable.
I actually think the opposite will happen.
Why invest AI compute in building an ASIC when you can make an 100x better x86?
I'm not convinced the economics of general purpose computing change.

Congratulations on the launch Shan and team.
A timely answer to a problem the country can't afford to ignore.

Don’t worry about deposit and withdrawals anymore.
One integration for every way money moves.
The new money stack begins with H and ends with alliday.
In the latest episode of StablePulse, I sat down with @griffintier - CEO of @hallidayHQ.
The point of entry (AKA "deposits") is one of the least talked-about aspects of neobanks, trading platforms, etc. But it's also one of the most important.
It doesn't matter how awesome your application or protocol is - if your users cannot seamlessly move funds into the application, you are dead.
Griffin successfully convinced me that the issue is, as always, fragmentation. Your users are holding money in a plethora of locations and a plethora of form factors. They should not have to move that money around to get it into your system.
I urge every single application out there to DM Griffin to learn more. I will gladly connect you. He told me that he has been able to improve deposits, and subsequently revenue, by 150x for some applications.
Ignoring this will lead to the certain, slow, and painful death of your company.

Smart contracts will win.
Self-custodial composability will win.
Verifiable computation will outlast and outgrow opaque alternatives.
A startup doesn't have to be your life's work, but if it is, you become much harder to defeat. You play the long game and you outlast everyone. Because practically everyone else is an opportunist by comparison.

It is the year 2049 and the US Congress ratifies the PEA: the Protocol Enforcement Agency.
Its mandate: no decentralization theater. Code is law, or be dealt the law.
Half-joking. But, the uncomfortable truth is that decentralization is too important to leave unenforced.

We really need to bring back the social requirement to produce white papers in crypto.
This must happen, lest we see smart contract authorization replaced with AWS IAM.

We just shipped a new AI productivity feature at Halliday!
Integrate in minutes using our new Halliday Claude Code plugin.
I built a complete crypto onramp and deposit app in five minutes without writing any code.
Fired up the new Halliday Claude Code plugin and it handled nearly everything.
Tech stack:
- React app with Vite
- Reown / @WalletConnect
- Wagmi + Rainbowkit for wallet connection
- @HallidayHQ for fiat onramps, swaps, and crypto deposits
The plugin knows the Halliday SDK, clones open source examples, answers specific questions using docs context, and even helps debug.
In the video you'll see:
- How to set up the Halliday Claude Code plugin
- Get a free Halliday API key in seconds
- Clone an open source repository in one prompt
- Change the in-app styles
- Automatically adjust the Halliday SDK configuration
- Do a real cross-chain crypto deposit in seconds with stablecoins
Claude Code is a game changer. Anyone can build powerful apps with crypto rails in minutes. Links below.
Tell us what you're building in the comments.

Excited to share our new withdrawal flow!
We meticulously crafted a UX to remove the friction from withdrawals.
Offering a great withdrawal UX on your platform drives user retention and builds trust.
This ultimately leads to more deposits!
Check out the video below:
It is Friday and it is time to ship a new product capability: unified withdrawals.
Drive retention and build user trust with a UX optimized withdrawal flow.

The most important question for your crypto app: what % of users convert at the point-of-deposit?
We went full stack to solve this: bare-metal fiat to self-custody orchestration on one integrated backbone.
No patchwork. Just one single system optimized to grow your revenue.
Onboarding flows lose >50% of users to a fragmented, confusing user experience.
Swap on one site. Bridge on another. Ramp on a third. Log into your exchange. Give up.
Halliday fixes this with a unified product optimized for conversion ↓
