nixorokish explained that the Frame transaction EIP is now Scheduled for Hegotá, while Derek Chiang stressed that the SFI only signals that Ethereum will ship AA in Hegotá, not that 8141 as written or even its number is settled; he argued at ACDE against making the SFI decision now. nero_eth pointed out that 8141 lets privacy pools sponsor withdrawals directly from the withdrawal amount, with no relayer. A Circle researcher proposed letting ecrecover read post-quantum signatures from 8141 transactions, giving immutable contracts a migration path. AnkushinDaniil proposed a single opcode and frame-mode registry for the frame transaction family.

After the SFI: what is settled for 8141 and what is not

EIP-8141: an opcode and frame-mode registry for the frame transaction family

(AnkushinDaniil), submitted. The 8141 family (8141, 8250, 8272, 7906, 8288, 8312) allocates opcodes and frame modes per draft, which has already caused two collisions: `0xB5`, assigned by EIP-8272 to `RECENTROOTREFLOAD` and later used by 8141 for `SIGDATACOPY`; and frame mode `3`, assigned by EIP-7906 to `POST_TX` and also claimed by EIP-8312 (UTXO). 8141 would hold the authoritative allocation that dependent EIPs draw from.

Post-quantum migration: ecrecover

ethresear.ch: proposed PQ upgrade for ecrecover

22:08 (mirabelenkiy-circle). Many contracts verify ECDSA signatures with ecrecover and are exposed to quantum attacks; rather than disable it, ecrecover could read post-quantum signatures from EIP-8141 frame transactions, with the 65-byte `(v, r, s)` encoding lookup values and a sentinel value triggering the new path. The aim is a graceful migration for immutable contracts, not a fix for EOAs themselves. The author notes the EVM defines ecrecover as a pure function, so any public key lookup raises backward compatibility questions.

Ethereal news #37

20:50: Glamsterdam repricing impact for contract developers, the Revolut euro stablecoin rolling out, and native AA scheduled for Hegotá. Security: about $8.5M drained in the Term Finance governance incident, a roughly $1.5M Sandbox bridge exploit, and a Ledger clear signing flow bug fixed in the Ethereum app.
