There’s a generational shift happening, and Coinbase is uniquely positioned to capture it: 1) The onchain economy has reached escape velocity 2) Coinbase's full stack platform is powering it 3) The next frontier is agentic and on Coinbase Our thesis is simple: crypto is the best form of money, and the infrastructure will overhaul the existing financial system. If it involves money, it will involve crypto. Coinbase is uniquely positioned to capitalize on this transformation. Some highlights from our earnings today: - Gained share in both spot and derivatives globally, reaching an all-time high in crypto trading volume market share - Saw huge growth in derivatives trading volume, driven by our Everything Exchange - 10x increase in stablecoin transaction volume on @base - USDC on our platform hit another all-time high - >90% of onchain agentic stablecoin transaction volume is on Base - 12 consecutive quarters of net native unit inflows- customers have been adding more crypto to Coinbase every quarter

True: "Transformational products deliver tangible value at 1000x the rate of charities whose value cannot be tested in the market place." Sadly, many (most?) charities don't just create little value. They often do net harm by getting captured by political agendas, bureaucracy, or bad incentives. Wealthy people often do philanthropy for tax optimization more than results. A neutral-to-slightly-positive charity can still beat giving that money to the government (depending on local waste/fraud levels), but it's a low bar. If you actually love humanity and want to help people: practice capitalism first. Build products people voluntarily pay for and use. Taxes and philanthropy are distant seconds.
The lesson I take from the SpaceX IPO is that the only thing stopping us from solving arbitrarily difficult problems is extreme creativity in business models. No amount of tax and spend programs got us reusable rockets and great electric cars. Customer delight is a necessary precondition for success. There seems to be some discussion around whether successful entrepreneurs should give up control of their companies so they can subsidize some philanthropic venture that otherwise has no value prop sufficient to run it as a business where customers voluntarily exchange money for goods and services at a competitive and reasonable price. This misses the point. Transformational products deliver tangible value at 1000x the rate of charities whose value cannot be tested in the market place. Think about the undeniable value of the smart phone, satellite Internet, electric consumer devices, etc etc. I think the transformational moment for SpaceX was when Elon stepped away from the philanthropic Mars greenhouse concept and fixed his resolve on unlocking radically better rockets for humanity. The greenhouse would have been, at best, a neat trick. Falcon and Starship give humanity a durable economic engine to maintain and improve access to space, forever.

I can’t believe Anthropic comparing their product to nuclear weapons 800 times backfired on them. I am shocked

.@paulg's quote is a good prompt for your agent to make anyone's writing more concise "strive to make my writing unsummarizable, in the sense that it has so little fluff left in it that if you take any words out, as summaries by definition do, you lose a lot of interesting ideas" i've been testing voice dictation, which then runs through this prompt, for messages to colleagues

The most frequent feedback I get (especially at @coinbase) is that I could be more concise, or "Can you make this into a bullet point?" My usual defense was that I'm not trying to transfer information. I'm trying to infect people with a way of thinking or an idea. The bullet gives you the conclusion without the path, and the path is what changes how you see the next ten problems. And while I agree with my defense, it can also be an excuse. I kept trying to be more concise, but I didn't have a good forcing function for it, because "the idea needs room" justifies any length. This tweet from @paulg last week really stuck with me. I think about it every time I write now. (my agents too) P.S. This could probably be summarized better.

Replying to @bourscheid
No, you don't get it. He does not have $1 trillion sitting in cash, it is 99% stock in his companies. To make that wealth liquid would mean selling all that stock which would swiftly destroy *both* the companies (Tesla, SpaceX, others) and the wealth. If he sold it all, he'd end up with maybe $100b max, several hundred thousand people would be out of work, the companies ruined and many of their suppliers also ruined. Okay, but now Elon has $100b in cash, and can "solve the world's problems". $100b divided by the world's 8 billion people is $12 If you were in charge, several of the most innovative industrial companies in the world would be destroyed, hundreds of thousands out of work, and space would again close to human civilization for another generation. But everyone on earth could have one nice meal and you could revel in your altruism.

Cross-border payments don't need to be inefficient or unnecessarily complex. For businesses sending money around the world, stablecoins offer the path of least resistance.
It’s a good day for B2B cross-border payments. @MassPay_io is bringing the power of Coinbase payments to their global enterprise customers. Eligible MassPay clients can now send USDC instantly, anywhere in the world.

Now you can use your favorite AI agent to control your Coinbase account (or a sub-account), with Coinbase for Agents. Here’s a quick demo on how to set it up and some of the cool things you can get your agent to do.

We're excited about the US CLARITY Act. We think all YC companies will use crypto technology, like stablecoins, before long. Not just crypto startups, not just fintech startups, but every company. Here's why this law is such a big deal 🧵 x.com/SenLummis/status/20637…

The Clarity Act passed committee. The floor is next. We did not come this far to quit at the 5 yard line.

Creative idea. This is better product market fit that one-size-fits-all education.
Alpha School is building 4 types of high schools: Service, Division 1 Athletics, Entrepreneurship and "get into a Top 20 university" high schools: Service high schools will be where you do things like spend a year in Africa building an Alpha School and doing your top 1% academics 3 hours a day, but on site on a different continent. D1 Athletics high schools will be where you spend 5 hours a day building yourself into an elite college athlete, maybe with professional aspirations. Again, you'll do your top 1% academics in only 3 hours a day, opening up most of your day to be an incredible athlete. Entrepreneurship high schools like Founders School run by @nateliason will be where you learn how to earn a million dollars in profits during high school, starting at 12 pm, and only after doing your top 1% academics in only 3 hours a day. "Get into a top 20 college" high schools will have a focus on giving you 40 hours a week to build a portfolio of Olympic-level (academic) extracurriculars to go along side top 1% academics in only 3 hours a day. The common theme here is that when it is possible to get a 1560 SAT and 10 APs during high school in only 3 hours a day, teenagers can open up their schedule to spend their years doing the stuff they want to at the highest levels. This is much different than the best private high schools where classes and homework take up so much time that students only have at most ~20 hours a week to work on their passion projects and leadership activities. Alpha School gives teenagers 2X the time, which makes for much more interesting people at the age of 18. That's why I'm building Toronto into the first 1,000 student Alpha School city. Reach out if you are interested.
