Ethereum developer Marchhill has submitted draft EIP-8437, proposing that the eth/73 protocol carry Proof Wrapper data. An optional mode would let transactions send raw signatures to an aggregator without first generating a STARK proof.
The proposal would also let authenticated program packages travel with transactions. A specified program could then run in a resource-limited sandbox to independently check witness data, rather than requiring a separate native adapter for each signature scheme. Other planned measures include limiting batch-queue size, clearing expired transactions and rechecking records before proof generation to support retries after failures.
This is a proposal, not a deployed change. ChainCatcher reported on November 12, 2026, that EIP-8437 remained in Draft and had not been merged. The developer said VM and key-binding consistency checks, cryptographic validation and performance testing were unfinished; benchmarking had not yet been done.
