Since its launch a year ago, my web3 security company has both paid out to security researchers & profited >$1,000,000 USD. Secured Aave, Uniswap, LayerZero, Ethena. We are celebrating with a giveaway. You need to like, retweet & comment. 4 winners, $500 each, 48hrs. Good luck🫡

I just opensourced something I have been working on for months. I call it “super prompt” because it also allows some LLMs (claude) to come up with really novel ideas, (picture is an example the prompt is larger). Its built in XML agent format btw. Github in comments.

Falcon 9 is now ~75% reusable and requires several days between flights. Starship is designed to be 100% reusable and ultimately be ready to refly within an hour of landing. This is the key to becoming a multiplanet civilization.

Elon Musk, 13 years ago: A fully and rapidly reusable rocket is barely possible. SpaceX is going to try to do it. We could fail, but we're going to try to do it.

I've watched over 1000 videos that helped me to become a security researcher. But many of them were a complete waste of time. Here are 8 channels that will help become a great web3 developer/auditor: 🧵

The latest addition to the list is Abracadabra @MIMSwap by @0xScourgedev for @GuardianAudits It is a high-quality, stateful Echidna & Medusa fuzzing suite with advanced scaffolding. Links below👇

I am pretty sure @MistralAI just delivered. We just gotta fine tune it and get it gguf'd and mlx'd and we will have our wish

Fine tune a model on Apple Silicon with Apple MLX, convert it to gguf and use Ollama for inferencing everywhere was number 1 in my wish list for 2024! DONE Next: GPT-4 level open source LLM @erhartford @Teknium1 @maximelabonne @Weyaxi @argilla_io @winglian We count on you! 💪

Here's a 🧵 about a bug pattern I've used to get paid across 5 bug reports totaling $150k. This very bug pattern has been the culprit behind significant hacks, leading to losses of $464k in Wise lending and a staggering $6M in MIM (the protocols I missed 😅)

In November, I submitted a critical bug to Cronos (@cronos_chain) which they downplayed and have since been kicked off Immunefi. Here's some info about the bug and an example of how projects can simply not pay a fair amount. Report: gist.github.com/fatherGoose1/6… tl;dr: - It's a…

Published chapter 2 of my hack series. In this chapter, I look at the recent Affine Defi exploit - while the attack itself was pretty straightforward, there are some good engineering and security lessons here. link.medium.com/QoAWuF60sHb
