Enforcing Transaction Simulation Integrity: Pectra Edition
Transaction simulations can be misleading due to 'state divergence' - critical on-chain conditions changing post-simulation. This post explores how to enforce simulation integrity by embedding 'state constraints' within transactions, leveraging EIP-7702 and ERC-4337, to ensure your intended outcomes are what you actually get on-chain.

Open Sourcing our MEV Launchpad: Multiplexer
Trying to nail that perfect arbitrage, execute a complex multi-step DeFi strategy, or even simulate a frontrunning attack often means wrestling with multiple transactions, timing risks, and callback hell. We faced these challenges constantly while intercepting attacks at Bitfinding. That's why we created Multiplexer, our internal engine for crafting powerful, precise, atomic Ethereum operations. Today, we're proud to open source it for everyone.
