After the Binance theft, account security is the main thread. A revision to EIP-8151 would let EOAs that permanently disable 7702 delegation through EIP-8476 keep using permit signatures, and the Ethlabs weekly stresses that 7702 itself was not broken. Frame Transaction (EIP-8141) merged a breaking fix to its nonce boundary. On post-quantum work, EIP-8479 was submitted and @ethereum published video from the Cambridge PQ workshop.

The security boundary of EIP-7702 delegation: permanent opt-out and permit compatibility

EIPs PR #12605: EIP-8151 treats the 0xef0200 opt-out marker as a qualifying EOA

Opened at 16:01. EIP-8151 (Account Code Restricted ecRecover) currently lets only accounts with empty code or a `0xef0100 || delegate` designator use `ecrecover`. If it shipped alongside EIP-8476, permits signed by accounts that opted out of 7702 would return an empty result, which contradicts the intent of removing only the delegation ability while keeping normal EOA behavior. The PR simply adds the EIP-8476 marker to the qualifying set.

Ethlabs week 19 update

Published at 18:33, quotes Derek Chiang's note from 10-30: 7702 itself was not compromised, and people using 7702-capable wallets (MetaMask, Uniswap, Ambire and others) do not need to panic. Barnabé expects more onchain rate limits and circuit breakers run by agents on top of the new account capabilities.

EIP-8141 Frame Transaction: nonce boundary fix

Post-quantum: the Cambridge workshop and PQ PeerDAS

Cambridge post-quantum workshop page

@ethereum: video from the Cambridge post-quantum workshop, posted at 00:03. It says AI progress is compressing estimates of the quantum threat timeline, and that experts met in Cambridge to coordinate the upgrade to quantum-resistant cryptography. See the Cambridge post-quantum workshop page.
