  • Latest all core devs – execution (ACDE) call video. Notes from Christine Kim:
    • Impact of EIP6404/6466 SSZ transition on existing contracts using RLP: EIP6404 is low impact whilst EIP6466 is manageable due to upgradeability of 3 impacted projects [Reminder: SSZ EIPs already removed from Dencun upgrade]
