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?

My first accepted finding on @code4rena, 1.5 year ago, 900 USD of payout ERC777 reentrancy, how cute 😂 Yeah, those were good times... With a coded PoC, btw ☝ https://github.com/code-423n4/2023-01-reserve-findings/issues/297

Good points and deep analysis of the contest platforms by @s0ck.eth. C4 has created a new open work paradigm that I don't know of any analogy to. https://twitter.com/sockdrawermoney/status/1798643063172313554

Pushed a few warnings about the differences between Kovan and Mainnet Glider. Good to see the tool is progressing and becoming more comfortable to use. If you want to start writing your ultimate query in 5 min to find millions of bugs, *check the repo*: https://github.com/ustas-eth/daily-glider
