As a pre-devcon treat, @ethPandaOps just launched a short-lived Pectra testnet: Mekong 🏞️ You can use it to try out EIP-7702, MaxEB consolidations, and more 😄 blog.ethereum.org/2024/11/07/int…

Another CertiK shitshow: Shentu OpenBounty, see below thread for context how they host a BBP w/o authorisation of projects, is literally leaking findings on-chain. This is insanely irresponsible and most probably even illegal! CertiK is a bunch of fucking criminals at this stage.…

Today I was contacted by OpenBounty (@ShentuChain) to add their platform to Web3 Bug Bounty alerts. Never heard about them before so I decided to investigate as it seemed a bit sus 1/6

Excited to publish the REVM Compiler, revmc! (@DaniPopes 1st author) We used LLVM to lower EVM bytecode into native code. We demonstrate 19x gains for the Fibonacci benchmark and synced Ethereum mainnet with revmc enabled for the hottest 250 contracts! Read on to learn more!

On March 26, Munchables suffered a 17,413 ETH hack, worth roughly $63 million. The perpetrator was later identified as one of their own developers, allegedly affiliated with North Korea. Today, I'm sharing a private investigation into who the hackers are and how they operate.

Jackson has a job at FAANG and as if that wasn't enough, he also does audits on the weekends. 👀 But few know that investing is his favourite topic, and also how he has made the bulk of his wealth. Today, we talk about his approach to such topic, and much more! 💰@sjkelleyjr

One of the weirdest side stories of the Munchables exploit was the second exploit TX - blastexplorer.io/tx/0xfc7bfbc38… As we were monitoring the exploit live in the Juice Fi war room, we simply could not understand why they didn't steal the entire (Juice's) $20M+ in WETH that was…
