A Saturday. pochenai submitted an EIP-8130 fix so two EOAs with identical transaction data cannot reuse one payer signature and drain the payer's gas deposit. ethresear.ch analyzed "universal overflow" for EIP-7999, keeping the legacy scalar gas retention pattern around CALL in a multidimensional fee market. BrianBland proposed an ERC-20 transfer authorization scheme using 2D nonces.

(pochenai), submitted: the payer signature hash includes a from field, but the spec did not say what goes there on the EOA path where from is empty; encoded as empty, two EOAs with identical transaction data would share a payer hash, letting the second reuse the signature and drain the payer's gas deposit, so the recovered sender address must be substituted.
00:42: analyzes "universal overflow" for EIP-7999 as a minimal way to keep the legacy scalar retained gas pattern around CALL while avoiding pricing all EVM gas at the most expensive resource; it credits Vitalik for the main idea.
(BrianBland), submitted: ERC-20 transfer authorizations split nonces into (uint192 nonceKey, uint64 nonceSequence), mirroring ERC-4337's semi abstracted encoding, so repeat payments to one counterparty use one storage slot per (payer, key).
