In a weird way, everybody is rooting for you. When you go to a job interview, the interviewer wants you to be amazing so they don’t have to look anymore. when you go on a date, the person wants to have an amazing date with you. If you make a piece of content, people want to see amazing pieces of content and they have no problem if it’s yours.
the instant you get into the mindset that people want you to do well, your entire world gets better. And you’ll be shocked to know this pattern keeps repeating in different areas of life.
A little late to announce this, but I joined the engineering team at @meleemarkets back in September. Been heads-down building ever since.
Stay tuned 🚀

- blockchains did not scale until 3 years ago, at best
- regulation was crippling until 2 years ago
- right around that time, the most fundamental tech breakthrough of all time happened (AI, which has been studied for decades btw)
- all greenfield from here for crypto
prediction markets are live sociological experiments in how we process information and price uncertainty. Watching people arrive at a shared version of reality (or fail to) is a big part of the appeal for me.
Just arrived at Solana Summit in Belgrade. First conversation of the day, I mentioned to @maxh2onodes that I’m still interviewing for Solutions Engineering/FDE roles. Someone at the next table overheard us, came over to say they’re hiring, and I’ve already sent them my CV.
The biggest cheat code for getting hired in crypto is genuinely just going to @superteam events and talking to people.
I moved from Berlin to Cologne about 4 months ago. Being close to family is unbeatable, and Cologne gives me the stability and headspace to focus more on things I believe in. But I miss regularly talking to inspiring people who are building big things and dreaming bigger. How do people cultivate that kind of circle when living outside places like NYC, SF or SG?
What's the one question you ask before joining a startup now that you didn't earlier in your career?

Being around cynical and dour people is just so unpleasant that I have developed some sort of deep ick for it. You have so much you could be doing, so many things you could root for, but you choose to hope for bad outcomes, harm, doomerism, and failure? Ew
Wrapped up my time as Integrations Engineering Lead at Wormhole, took a break to level up my Salsa dancing 🕺and I’m now open to my next role.
Over the past 6 years, I’ve worked at crypto startups building backend services for trading systems, integrating exchange APIs, contributing to wallet infrastructure and dApp integrations, and improving developer tooling.
At Wormhole, I led partner integrations and developer enablement across EVM, Sui and Solana. I worked hands-on with partner engineers from onboarding to mainnet rollout, contributed in Solidity, Rust, and TypeScript, built and improved SDKs, CLI tooling, docs, tutorials, and integration guides, ran workshops and partner sessions, and helped turn developer feedback into product and DX improvements together with Product and Engineering.
I’m especially interested in Solutions Engineering or similar customer-facing engineering roles where I can stay close to the code while helping customers and developers successfully integrate, adopt, and get value from a great product.
DMs open, intros appreciated 🙏
Looking for help to fact check my understanding of HIP-4 & reinsurance:
HIP-4 turns insurance risk into a tradable binary market. If that works, it could enable a form of permissionless reinsurance.
Instead of an insurer “promising to pay,” you buy a position that pays out if the bad event happens.
The payout is enforced by the contract itself.
In traditional reinsurance, underwriting means
assessing risk and deciding whether to take it, at what price, and under what conditions.
Pricing is set by humans. With HIP-4, pricing is discovered by the market. Anyone willing to take the other side effectively becomes the reinsurer.
Platforms like Kalshi and Polymarket already enable outcome trading, but they have not enabled reinsurance-like risk transfer at scale. The bottleneck is not demand for risk. It is that traders cannot efficiently hedge and warehouse risk at scale.
As a result, liquidity often depends on incentives rather than purely organic risk transfer.
HIP-4 takes a different approach:
A vertically integrated system (spot + perps + outcome contracts) in a single unified margin account that lets traders hedge correlated risks instantly.
For that to work, there are some key assumptions that need to hold:
• event definitions and oracles that are objective enough for large capital to trust
• system solvency under stress
• capital efficiency is sufficient for traders to deploy meaningful size
Shoutout to @reisnertobias for bringing up the HIP-4 and reinsurance angle at the Hyperliquid Germany meetup.

Ok my understanding now is that they didnt get access to the private keys themselves at any point. Instead they just managed to make them sign malicious transactions ( likely because its hardware wallets )
So the problem for the attacker is that they need to coordinate two signed transactions to execute at the same time, otherwise you'd risk warning the victim.
Thats what they solve with durable nonces. They dont know when each victim will be at their computer to sign a transaction, so they used durable nonces to make it irrelevant
