  • pcaversaccio joins the EF board
  • all Glamsterdam Core EIPs promoted to SFI
  • EIP-8141 mempool replacement and log semantics merged
  • Nethermind and ethrex cross-test 8141
  • PQ1 post-quantum hardware wallet

The EF blog announced that pcaversaccio has joined the EF board for an initial one-year term on a voluntary basis. poojaranjan submitted an EIP-7773 change, based on ACDC #183 decisions, promoting all Glamsterdam Core EIPs to SFI. EIP-8141's mempool replacement, eviction and payer exposure rules and its transaction log set semantics merged; a Nethermind implementer cross-testing against ethrex found three ambiguities and submitted clarifications. An EF livestream presented Freedom Factory's PQ1 post-quantum hardware wallet, which per Ethereal news #33 provides SPHINCS+ signatures for ERC-4337 smart accounts.

  • ERC-8286 modular accounts for frame transactions
  • EIP-8141 charged_gas fee settlement merged
  • ERC-8262 zero-knowledge compliance oracle
  • EIP-7906 POST_TX enforcement
  • Vitalik on diamond iO

ERC-8286 merged as a Draft, defining an EIP-8141 frame transaction validation extension for ERC-7579 modular accounts: a validator returns an approval mode that the account applies with the `APPROVE` instruction in a VERIFY frame. soispoke's EIP-8141 `charged_gas` fee settlement change merged. ERC-8262, a zero-knowledge compliance oracle, merged. Vitalik published the second part of his cryptographic obfuscation series, on diamond iO. Barnabé said a Lido upgrade cuts its validator count by almost 30%.

  • EIP-8151 applies account code restriction to ecRecover
  • native privacy in Hegotá
  • Stellar Private Payments design
  • proprietary AMMs and Ethereum
  • ACDT #89

colinlyguo submitted and merged an EIP-8151 change that extends EIP-3607's account code restriction to `ecRecover` while keeping the EIP-7702 delegation exception, protecting immutable contracts once accounts move to code-controlled authorization, including post-quantum schemes. nero_eth said Hegotá will make privacy applications first-class citizens of Ethereum, removing trusted relayers and preparing for partial stateful nodes and post-quantum. mikeneuder and maryam analyzed proprietary AMMs on ethresear.ch. ACDT #89 and RPC Standards #31 were held in the evening.

  • EIP-8333 aligns checkpoint with epoch boundary block
  • kohaku-cli unshields multiple Tornado notes in one UserOp
  • Solidus formally verified compiler challenges
  • ERC-8349 multi-facet proxy

EIP-8333 merged as a Draft: epoch N's FFG checkpoint moves from the block at N's first slot to the last block before N, removing the race where a late block splits the first committee's votes and fixing the off-by-one where "epoch N finalized" really meant one extra block. kassandraETH improved kohaku-cli, which can now unshield multiple Tornado notes in one UserOp. gakonst published challenges for Solidus, a formally verified EVM compiler.

  • EIP-8141 mempool replacement and eviction
  • payer exposure bound
  • transaction log set
  • canonical paymaster implementation
  • signature scheme registry

EIP-8141's mempool and paymaster sections moved together: svlachakis submitted a mempool lifecycle definition where pending identity is `(sender, nonce)`, replacements must bump both fee fields, and summed pending maximum costs for any payer cannot exceed its balance; he also submitted the transaction log set and unrolled-batch log semantics, and a concrete canonical paymaster implementation. AnkushinDaniil submitted two RFCs, a signature scheme registry and recognizing the canonical paymaster by stable identity. Blob support, direct evaluation of validation prefixes, the APPROVE gas cost and fee field bounds, submitted the day before, merged. zeam announced its EF grant has ended.

  • ACDC #183
  • first public testnet targeted for September
  • devnet-8 and devnet-9 plans
  • EIP-8141 canonical P256 sender account and passkeys
  • direct evaluation of protocol-defined validation prefixes

Per Ethereal news #32, ACDC #183 set devnet-8 for early August with minor repricing changes and discv5-only execution layer discovery, devnet-9 for August non-finality testing, and the first public testnet for September; new Hegotá proposals include EIP-8334, EIP-8341, EIP-8321 and EIP-8015. Four EIP-8141 changes were submitted: a canonical P256 sender account that lets passkey accounts enter the mempool without simulation, direct evaluation of protocol-defined validation prefixes, the APPROVE gas cost, and bounds on fee fields. misilva73 submitted an EIP for offline state migration to the PBT.
