Hi! Per @timbeiko encouragement...would love to spend 5-10m to present some reth-related slides, how we intend to interface with ACD etc, as well as leave some time for Q&A!

I'd like to discuss a couple of questions:

• Is Update EIP-4788: post audit tweaks EIPs#7672 included in devnet9?
• Should system address 0xff..fe be removed after an EIP-4788 system call if it was previously existing but empty? There are quite a few scenarios in execution-spec-tests that have that. Right now it is not in geth (and in erigon) because SubBalance, unlike AddBalance, doesn't touch the address when the transferred value is 0.
