A daily record of what changed in Ethereum protocol work, research and the ecosystem.

EF Protocol held an AMA on r/ethereum, with questions on client funding, what frame transactions mean for post-quantum, single slot finality and more. Blockspace Forum's multi-party block construction (MPBC) went live, letting the most valuable block take transactions from several builders. binji kept pushing to include quick slots (EIP-8198) in Hegotá, and Prysm published its Hegotá tier list.
On account abstraction, ERC-7562 (AA validation rules) moved to Review; AnkushinDaniil proposed two optional extensions letting keystore and frame accounts share one authorization step and making key change signatures portable across models and chains. The Hegotá meta EIP-8081 merged ACDE #245's DFI decisions. zsfelfoldi argued that recursive STARK pre-authorization (EIP-8288) would sharply cut the onchain cost of statelessly verifiable witness data, including trustless log index proofs.
Derek Chiang disclosed that the account abstraction collaboration between EIP-8130 and EIP-8141 (frames) broke down last week, and Base and Ethereum will implement different AA standards. The same day ERC-8286, "Modular Accounts for Frame Transactions", merged an update, while EIP-8130 submitted two spec syncs with Base's canonical repository. AnkushinDaniil argued that public-mempool gas sponsorship cannot work without locked funds or offchain trust, which is why EIP-8141 reserves balance.
A burst of EIP-8288 revisions on Sunday: Vitalik retitled it "In-mempool signature and proof aggregation", and ilitteri submitted a series of PRs specifying the aggregation circuit's properties, where a dependency verification frame may sit, its receipt, and its exclusion from atomic batches. An EIP-8141 PR proposed admitting paymasters by a node-decidable egress property rather than an exact code match. SizzLean released a formally verified Lean 4 SSZ library.
Saturday's work focused on mempool safety and gas calculation for frame transactions. An EIP-8141 PR proposed four rules to cut validation amplification from malformed transactions and shared payer changes. EIP-8130 submitted a fix (merged on the 16th) so EIP-7623's calldata floor applies to its transaction type too. binji and others discussed ZK KYC and zk passports.
After frame transactions became the Hegotá headliner, ethrex said its implementation now runs two public testnets; Derek Chiang explained EIP-8288 in plain words, calling it one of the most groundbreaking possible updates to Ethereum. EIP-8250 merged a fix keeping EIP-8141's nested `fees` list in the transaction payload. Bermuda, a privacy solution for the Safe ecosystem, launched with privacy pool funds controlled by a Safe.
ACDE #245 set frame transactions (EIP-8141) as Hegotá's execution layer headliner and Declined for Inclusion (DFI) 14 EIPs, including the account abstraction proposals EIP-7819 SETDELEGATE and EIP-7851 code-controlled EOA delegation. Vitalik posted that PBT stores contract code separately by codehash, a chance to clean up the multiple code delegation methods such as EIP-7702 and SETCODEFROM. Ethlabs, L2BEAT and ethbeat released Hegotá rankings.
