Client Team Updates


  • Nethermind:

    • No particular update
      • Preparing a new release
  • Erigon:

    • Working on changes in the blob transaction pool to limit spamming
    • Working on testing their final release before Dencun
    • No other specific updates
  • Geth:

    • Guillaume was able to fix the syncing issue from block 1301 and is now syncing
      • Currently at block 1.7m

Chain Infra

  • Gateway
    • Working on client diversity for Chiado and mainnet
      • Will have Nimbus + Erigon and Nimbus + Nethermind pairs


  • We’re ready for the hard fork with a window of 1-2 months for releases and time for users to update
    • Nethermind and Erigon are committing to it


  • Issues during the hard fork
    • Erigon: the new pending transaction filter might leak memory (issue #9356), especially for blobs
  • Gnosis nodes were not up to date
  • One Gateway Erigon node was not up to date for 500 keys, but was fixed immediately
  • We should prepare diversity better for the next hard fork
    • EL: We kind of got there, but still more Nethermind nodes than Erigon
    • CL: No validators on Nimbus
      • Needs to be tested before mainnet


  • We should spin up a devnet for Aura Contract work

Hive Tests

  • No updates


  • Shutter
    • Received some traffic from the Shutter test system
    • Their documentation is a bit out of date, so working on figuring out some things
    • In general there’s some progress

Shadow Fork

  • Deploy same contract on mainnet than Chiado (deposit contract proxy)
    • Philippe will prepare it
