  • EIP-8141 P256 signature low-s
  • VERIFY frames statically excluded from atomic batches
  • blob support for frame transactions
  • EIP-2780 folds transfer log cost into TX_VALUE_COST
  • Starknet Falcon-512 account mainnet transfer

EIP-8141 kept converging: P256 signatures must use the canonical low-s form and VERIFY frames are statically excluded from atomic batches, both submitted and merged; svlachakis submitted a full specification of blob support for frame transactions. misilva73 merged an EIP-2780 change removing the standalone `TRANSFER_LOG_COST` (1756) and raising `TX_VALUE_COST` from 4244 to 6000 to cover both the recipient and the EIP-7708 transfer log. A spec-compliant Falcon-512 account made a mainnet transfer on Starknet for about $0.06.

  • EIP-8141 charges each ARBITRARY signature entry
  • transaction-scoped approval effects merged
  • frame transaction receipt encoding merged
  • EIP-8268 listed as PFI
  • ERC-1613 Gas Station Network back to Draft

lightclient submitted and merged an EIP-8141 change that adds a flat 100 gas per signature on top of calldata costs, so large numbers of empty ARBITRARY signature entries cannot underpay; it is an alternative to the MAX_SIGNATURES cap. The previously submitted transaction-scoped approval semantics and frame transaction receipt encoding were also merged. forshtat moved ERC-1613 Gas Station Network from Stagnant back to Draft because it is still used on Polygon, including by Polymarket. Aztec Alpha V5 brings client-side proving down to about 2.5 seconds on a consumer laptop.

  • Kohaku CLI privacy demo
  • unshield and swap in one ERC-4337 UserOp
  • EIP-8272 listed as Hegotá PFI
  • ACDT #88
  • Vitalik on AI capability growth

kassandraETH released a Kohaku CLI privacy demo on mainnet; per Ethereal news #32, it can unshield funds from Tornado Cash and swap in one ERC-4337 operation, and it is a work in progress without a security review. She also listed the only two HTTP endpoints the CLI talks to: the RPC and Pimlico's public bundler. EIP-8272 (recent root references) was listed as a Hegotá PFI. ACDT #88 was held in the evening; per Ethereal news #32, devnet-7 is in chaos testing and stable containers are about 10% to 20% slower.

  • EIP-8141 charged_gas and fee settlement
  • EIP-8250/8272 rewritten as deltas on 8141
  • opcode and TXPARAM collisions
  • mainnet privacy protocols tested
  • Zcash Ironwood

soispoke submitted a set of cleanup PRs for the frame transaction family: EIP-8141 uses `charged_gas` to tie together frame gas, the EIP-3529 refund and the EIP-7623 floor and applies it to fee settlement; EIP-8250 and EIP-8272 are rewritten to describe only their changes to 8141, and their TXPARAM and opcode assignments that collided with 8141 are resolved. kassandraETH tested Tornado Cash, Railgun and Privacy Pools deposits and withdrawals on mainnet with a homegrown CLI.

  • EIP-8141 spec clarifications merged in bulk
  • EIP-8272 signature charges and mempool hardening merged
  • EIP-7716 back to Draft
  • verifiable invoice commitment ERC
  • Unichain TVS drop

The frame transaction family fixes submitted over the previous two days were merged together: EIP-8141's SECP256K1 signature encoding, execution approval scope, FRAMEDATALOAD operand order and EIP-7623 calldata floor; EIP-8272's signature costs, TXPARAM constant, signature hash sync and mempool hardening; and EIP-8250's signature hash description. EIP-7716 anti-correlation penalties moved from Stagnant back to Draft with an excess-over-moving-average penalty design.

  • EIP-8141 restores EOA sponsorship
  • revert scope of approval effects
  • EIP-8250 nonce field charging
  • EIP-8272 signature hash sync and mempool hardening
  • EIP-7997 removes the irregular state transition

lightclient merged two EIP-8141 changes: codeless EOAs can sponsor transactions again, and the skipped receipt status code becomes 0x2. While implementing the frame transaction family, AnkushinDaniil submitted a batch of fixes: approval effects are transaction-scoped and not undone by frame reverts, EIP-8250's `nonce_keys` get charged, EIP-8272's signature hash is synced, and mempool handling of recent root references is hardened. soispoke said Glamsterdam will raise block gas from 60M to at least 200M.

  • ACDE #241
  • at least 3 months to mainnet
  • Hegotá proposal deadline August 6
  • EIP-8141 spec clarifications
  • EIP-8341 partial execution payload commitments

ACDE #241 confirmed that glamsterdam-devnet-7 is open to app developers (300M gas limit), that devnet-8 is likely the last devnet before public testnets upgrade, and that mainnet is at least 3 months away; the deadline for non-headliner Hegotá proposals is August 6. svlachakis submitted a set of EIP-8141 spec clarifications covering signature encoding, execution approval scope, storage refunds, the calldata floor and receipt exchange. chunter-cb submitted ERC-8340, which defines the byte layout of the `metadata` field in EIP-8130 transactions. Francesco (fradamt) moved from the EF to Ethlabs and said fast confirmation is already on Glamsterdam devnets.
