Re-introducing EVM Diff EVM Diff is the easiest way to diff EVM-compatible chains in a friendly format, now with automated discovery of chain differences, making it much more scalable There's two ways to diff: - Two chains side-by-side - All chain in a caniuse-like table

🚨 FAULT PROOFS & STAGE 1 HAVE ARRIVED 🚨 Open source, permissionless fault proofs are live on OP Mainnet, and with them the OP Stack arrives at Stage 1 decentralization. This is a major step forward for the Superchain!

Umbra v2 is looking really nice 👌

Introducing 🔴 OP Succinct 🔴 After a fun collaboration with Succinct and OP Labs, I'm excited to share OP Succinct — our minimal diff to upgrade an OP Stack chain to a full ZK rollup. Come inside and look around... 🧵

Interesting info about "Code Complete" in relation to building robust, secure software & learnings from several studies described in the book.. ..how it can relate to Smart Contracts and Blockchain development & security TLDR: "there are on avg. 10-20 bugs per 1K LOC" 🧵 👇

If you’re interested in helping us write quality and potentially vyper-inspired solidity at Optimism, my DMs are open

I tried to model optimism.eth permissions in Prolog (first time using it!), have a look: gist.github.com/lucadonnoh/fca… The threat model is that OP Labs and FND are malicious, but the Security Council is honest and active. It's not possible to steal funds, but only temporarily freeze.

Lots of new foundry cheat codes are now available in the latest forge-std release Check out the PRs linked in the release notes to learn more: github.com/foundry-rs/for…

Does anyone know of protocols/apps that have policies or guidance on things like: - How frequently they upgrade their Solidity or Vyper versions - How they determine when new compiler versions are considered safe for production use?

Hiring a rust-focused protocol engineer @ OP Labs - if you want to hack on: - kona (fault/zk proof framework for the OP Stack) - op-reth (Optimism extension to Paradigm's reth) - hera (rollup node) - OP Stack protocol - interop I want to hear from you! boards.greenhouse.io/oplabs/jobs/53…

🧵 As is often the case, the simplest solutions are the most elegant. Inspired by this principle, we've just proposed 🔑 ERC-7802 introducing a minimalist interface for token bridging. ethereum-magicians.org/t/erc-7802-cro…

WiEN was the highest signal newsletter and the only one I consistently read every week It was always exciting and motivating to be featured in the newsletter, especially when I was a newer dev I will miss WiEN, amazing work by Evan Van Ness 🧉 and abcoathup.eth 🐡 🛡️🦇🔊 over the years 🫡

HNY! Kicking off 2025 with a new opening on the OP Labs product team: Protocol Safety PM. In this role, you'll... 🦺 PM tools for safer protocol development 🤩 Work closely w/ Matt Solomon and smartcontracts.eth as your eng partners 🫀 Play a critical role in OP Stack releases

Welcome alcueca, super excited to work together!

Had a lot of fun working with Wonderland on this project, now go break it! Handmade secret op hacker merch for anyone who finds a medium or above 🥰
