1/4 SPCX/USD perps are now live on GMX. Trade pre-IPO exposure to SpaceX, one of the world’s most valuable private companies, with up to 10x leverage. SPCX is a new type of market, launching with limited initial OI capacity as GMX builds the infrastructure for pre-IPO perps.

The markets right now are rough but the amount of demand for instutional support for onchain infrastructure has never been stronger. Some exciting stuff coming out of @arbitrum and @Offchain that I can't wait to share. The economy is becoming programmable. Arbitrum Everywhere.

The programmable economy is creating entirely new businesses and founders are leading the way. That's why we launched Founder House - help early-stage teams like @bondoncredit accelerate their product and go-to-market on the Arbitrum Platform. Join us in London on July 10-12.

This is what the UK spyware proposal means. There must be government spyware on every mobile device. It shall watch everything that happens, including always watching the screen, looking for things the government disapproves of. When anything is flagged by the software as something the government doesn't like, the software must block it from being sent or displayed (in realtime). The user of the device must not be able to shut this watching and blocking off. The only way to shut it off would be to ask the government or its proxies to do so for you, at their discretion. Therefore the whole device must be locked down. Administrator rights and the decision of what software or operating system to run or not to run must be taken from the owner/user and handed to the government and its proxies. Apple and Google are themselves working hard to lock down the devices they are involved in to shut out competition and establish a duopoly. The UK government says it is "working closely" with Apple and Google and currently they synchronise and coordinate their communication on this subject. The UK government is now proposing to mandate what would otherwise be illegal anti-competitive practices. @GrapheneOS on the Apple and Google duopoly: x.com/GrapheneOS/status/2053… Statement from @signalapp x.com/signalapp/status/20640… @ReclaimTheNetHQ on the state spyware: reclaimthenet.org/starmer-ca… The government announcement: gov.uk/government/news/new-p…

One of the biggest mistakes we make in crypto is assuming people act rationally A great talk during the @arbitrum London Open House connected many of the industry's dynamics to the work of @kahneman_daniel and the idea that humans are often driven by biases rather than pure rationality Once you start looking at crypto through that lens, a lot of things deserve to be reconsidered: - price action - user preferences across products - the way people perceive the value of a project It's a coll idea and it opens an infinite number of questions. Very interesting Thanks @hummusonrails, one of the best presentations I've seen in a while

If you are a founder building in crypto this is for you! 💙

I used AI to find TEN vulnerabilities in a security audit 🧵 Millions of dollars are being lost to hackers every week in Web3. So I tested 3 popular AI skills on real competitive audits to see if they can actually protect founders. The results were NOT what I expected. The experiment: → Target: Real-world competitive smart contract security audits → Tools: 3 highly-rated AI skills → Goal: See if AI can genuinely assist (or even replace) a human security auditor. The results:
