ERC-8339 was reworked into receiver-attested transfers built on EIP-8141 frame transactions, with no escrow and no second transaction. Two EIP-8272 fixes were submitted; one restores EIP-8141's signature verification cost and signature calldata cost so frame transaction signatures are not under-charged. Starknet's privacy SDK and Wallet API went live. Jesse Pollak posted a long reflection on Base; per Ethereal news #31, Base will focus on global finance.
terencechain announced that glamsterdam-devnet-7 is live: on the execution layer, EIP-2780 and 8037 move state-dependent charges from intrinsic gas to runtime, and the consensus layer adds EIP-7688 progressive containers. EthSystems launched to build confidential systems for institutional Ethereum, with anchor funders including Bitmine, Sharplink and Joe Lubin. ethrex v21 ships initial support for the Hegotá fork and EIP-8141 frame transactions. Ben Edgington published the second post of his finality user research. kassandraETH called for wallets to make 4337 UserOps, 7702 delegations and unlinked transactions the default now.
chunter-cb merged a major revision of EIP-8130's authorization model: admin is `scope == 0x00`, and scope grants are `SENDER`, `POLICY`, `NONCE`, `SELF_PAYER` and `SPONSOR_PAYER`; payment authority splits into self-pay and sponsorship; ERC-1271 signing is no longer a separate grant but an encoding of operational authority; and the account lock is simplified to lock then unlock. The post-quantum attestation aggregators EIP merged as a Draft. ACDT #87 was held in the evening; per Ethereal news #31, glamsterdam-devnet-8's repricing EIPs will get minor changes.
A quiet Sunday. Barnabé's Ethlabs Week 3 said the team is preparing a faster-slot proposal ahead of the Hegotá non-headliner deadline: after 6-second slots were declined for Glamsterdam, carlbeek proposed quick slots (EIP-8198) to prepare the ground for future slot reductions. A post on ethresear.ch analyzed Sybil attacks on AUCIL, an auction-based inclusion list.
Saturday. jochem-brouwer's EIP-8037 fix was merged, bringing the calldata floor into block-level gas accounting. Barnabé argued that $100 million flowed to Robinhood Chain not because ETH is its gas token but because ETH is the money of Ethereum, and cited a new study counting about 8,500 physical nodes in Ethereum's validator network. Vitalik commented that AI 2040 and its detractors hold totally incompatible worldviews.
jochem-brouwer pointed out that EIP-8037's block-level gas accounting does not apply the EIP-7976 calldata floor, which matters for maximum block size and calldata repricing, and submitted a fix. The new ERC-8335 implements ERC-3009's `transferWithAuthorization` on the smart account instead of the token contract. auryn_macmillan's Interfold privacy auction closed, and he remarked on 500 ETH: people must really like privacy. etan-status proposed EIP-8115, 8116, 7807 and 8015 for Hegotá.
The EF published a Protocol Security team post on running coordinated AI agents against protocol code: the real work is not finding bugs but telling real ones from fake, and one public result is a remotely triggerable panic in libp2p gossipsub (CVE-2026-34219). The EIP-8130 transaction type renumbering and RPC extension were merged, and EIP-7906 gained per-address TXDIFF views. ameensol described the shielded pool design of Privacy Pools v2. Solidity v0.8.36 shipped with Amsterdam EVM support. ACDC #182 was held in the evening.
