  • Nethermind: Not much. Still working on Shutter
  • Erigon: Fixed an issue where trace_block was not returning correct rewards because of the block rewards contract. Was merged yesterday.
  • Geth: Small update: Struggling with the rewards computation code. We'll be in touch with Andrew.


  • Prysm: No updates.
  • Nimbus: No updates.

Chain Infra

Gateway : All set up for EDCON (May 19-23) Shared the API key yesterday, hasn’t received any updates from Burner Wallet. Would like to get a version of the wallet in order not to have any updates. Gateway is fine with increasing rps and nodes. Need information from Gnosis. Deposit UI needs to be updated for the hard fork.


Gnosis ran manual tests, everything seems to be ok. No updates from Nethermind.


No objections from Nethermind. Should be doable on Erigon’s side as well

Can we try for May 24, 2023? Consensus chain variables. We’ll keep the same ones as Ethereum mainnet. How many withdrawal blocks should we accept?. On Ethereum it’s 16. Worst case it’s around 1.3 million gas per block. This would iterate over all partial withdrawals in ~8 hours, which is very fast. We could do 8 withdrawals per block. In any case we’ll add 550k gas per block. We have to define a list of KPI we want to reach on Chiado to consider it a success.


Shutterized Beacon Chain No updates.

Withdrawals: Right now it’s fairly complicated to track information regarding withdrawals. We might need to change the signature of the withdrawal function. Should not be too complicated for Nethermind and Erigon. The contract would also require an update to track these changes


Hive:Added the integration with the withdrawal contract. Adding the way to test the balance of the contract and the amount on the accounts that have done withdrawals. Should be done by end of this week No ETA for the rest yet.
