After an incredible ride, I’m no longer with Hexens. I’ve loved every second of this journey - the team is absolutely phenomenal, and I’m so proud of what we pulled off together: - Long days keeping black hats out - Countless hours mastering new tech - Running the biggest CTF in the web3 history - That epic trip to Thailand Huge thanks to my mentors, friends, and colleagues. You’ll always hold a special spot in my heart. Deepest gratitude for everything. My path is still hazy, but the plans are ambitious - stay tuned. gg wp

The new @ethereum system smart contracts to be introduced in Pectra are insanely good for understanding how the low-level EVM works! Loaded with comments and pseudocode in the EIPs, you can see how the stack and opcodes function very clearly. 🧵👇

The world is burning, but my house will be filled with light tonight 🫴✨ This was my first Solana review. I'm glad I finally had the opportunity to make some sense out of the SVM account model. This is also my first 2nd place and the biggest reward after the zkSync 1.1M contest. Thanks pals!

Yesterday, I published my first dashboard on @dune.eth ✨ It provides basic real-time analysis for each deal on @legiondotcc using the data from onchain events: https://dune.com/os/legion-stats You can see the total numbers of investors, collected amounts, and the latest investments all in one place. Send me a DM if you have any features in mind, I'll try to implement them. If enough people are interested, I'll open source the queries later. And ⭐️ the dashboard if you find it helpful! Thanks!

By the way, check this out! My guide on how to run Copilot in VSCodium has become the most popular discussion in the repo over the years. Recently I had to play with it a bit and update the instructions, because there was some new release that broke everything 😛 See how I did it here: https://github.com/VSCodium/vscodium/discussions/1487#discussioncomment-11866388

My ledger tool, 4 deps! Basically a wrapper for a couple of libraries. Could be even smaller if implemented with a native CLI and txs parsers, but there'll be maintanence issues (I'm lazy).

Another one bites the dust... A typical developer job scam, this time with a cherry on top.

If code is law, then security researchers are lawyers? If only my mom knew, she would be proud :')

DuneCon 2024 was definitely worth the time, very glad I went: - talked to some people about my workflows in Glider - attended a talk with @vitalik.eth for the first time (this is the guy I trust with my ETH) - it was just good to hang out, free food and great organization as always! Excellent job @dune.eth

DSS was great! Thanks guys, very nice to meet you! I hope you stay for Devcon too, if not, until next time 👋 https://frames.neynar.com/f/48e7e775/c5fdb994

My first (and let's hope not last) contribution to Solidity has been merged! A little revision: address.codehash can produce two results for an account with zero code, depending on whether the account has balance or not (among other factors), which caused a couple of issues at least on @code4rena . My proposal added a warning to the documentation to reduce confusion among developers. Thanks to everyone who participated in the discussion! https://github.com/ethereum/solidity/pull/14793

Tired of fancy wallets with ads, fees (lmao), and no control over your network connectivity? Here it is, the final solution! A script to sign offline with Ledger: ✨Ledger Offline Sign ✨ https://github.com/ustas-eth/ledger-offline-sign

The highly anticipated (by me) results of @doublerpro mitigation are out! Thank you, @code4rena and the team, it's been nice working with you 🙌

Had a little time this weekend to finish the Ledger Offline Sign script. It'll soon be available through npx or git. The only things left, I think, are to add more tokens to the list (ideally parse them from somewhere), include other tx types, and reorder the inputs. Wdyt?
