GM! Buidlers

In this latest HashingBits issue, we’re diving deep into Ethereum’s All Core Developers Consensus Call #135, covering all the major updates in the Ethereum ecosystem. But that’s not all, we will dive into what’s happening in zkSync, Polygon, and Solana ecosystems, along with recent advancements in the AI & Web3 space. For developers, we’re highlighting new updates in tools designed to assist Smart contract developers and auditors. And of course, we’re also digging into the headlines about UwU Lend’s whopping $23.1M exploit and Loopring’s recent $5M loss due to vulnerabilities in Guardian 2FA.
