Protocol Calls & happenings

Meeting Notes

Testing Update

  • EEST
    • All lingering PRs are merged
    • We should wait for Devent 6 to settle before re-filling
    • EOFWRAP relies on evmone which is not yet on pectra-5. Will be turned off until evmone is ready (some 7702 edge cases)
    • Devnet 6 is a tiny change
  • Fuzzing findings
    • No new findings
    • Fuzzing fails if clients are not on the same pectra devnet level
    • Relies on new fields
    • Tracing should support new tracing field RIP-7756
      • PC zero to container is critical
      • Function depth is currently needed
  • Clients need to target Getting up to Pectra Devnet 5/6 (whatever the last devnet becomes)

Client & Compiler Update

  • Nethermind, Besu, evmone, revm, erigon, all no changes
  • Solidity - not much change, merged the base needed and testing.
    • Planning for Q1/Q2
    • Deciding which optimizations to do
  • Vyper
    • Not much change
    • PyVM EOF support?
      • unknown, Mario will ask snake charmers
      • Separate from EELS

Spec And Other Issues

  • EOF Metadata Section

    • An update after doing a spike for EIP-7834 (metadata section) in evmone and EEST. Ref.
      • Multiple optional sections makes things complicated.
      • Very different from other sections, needs new code paths
      • No suggestions for improvements, meets it’s goals
    • EEST Tests
      • could automatically add metadata to standard tests, or a subset
        • Probably via a marker
    • Design wise more optional sections make parsing more complex
      instead of a full re-filling.
      • If we are sure it can be osaka we could make it mandatory

  • EOFCREATE / TXCREATE potential features and scenarios - an opinion and/or counter proposals.
    andCross-chain addresses (deterministic, counterfactual, and nonceless)

    • Pitor reviewed doc
      • Scenario 1b is the preferred solution
        • EOFCREATE - sender+salt
        • TXCREATE - sender + salt
        • Predeploy (fka ISC) to load bootstrap contracts.
        • Drop EIP-7720 (EOF create tx)
    • Discussion talked about pre-reployed contracts
    • This makes TXCREATE more palitable
    • New TXCREATE EIP
      • Includes 2 toehold contracts - salt only and salt+=CALLER
      • Maybe an address-based nonce-toehold as part of EIP and not ERC
    • We need a plan B for not having TXCREATE
    • RIP-7740 - RIPs/RIPS/rip-7740.md at master · ethereum/RIPs · GitHub - Preinstall deterministic deployment factories
    • Pre-ERC - EOF deterministic deployment contracts ethereum/ERCs@master…shemnon:ERCs:eof/txcreate-factories

  • Start work on Osaka-1 spec changes out of time
