ChainCatcher reported on November 12, 2026, at 12:22 UTC+8 that Ethereum developer Marchhill had submitted a draft of EIP-8437. The proposal would propagate Proof Wrapper data through the eth/73 protocol and add an optional path for submitting raw signatures to an aggregator without first generating a STARK proof.
Under the proposal, authenticated program packages could travel with transactions. A specified program would then run an independent check in a resource-constrained sandbox to verify witness data. The intended benefit is that new programs would not require a separate native adapter for each signature scheme.
The draft also proposes limits on batch-queue size, removal of expired transactions, and a recheck of records before proof generation to support retries after failure. These are proposed mechanisms, not demonstrated performance improvements: EIP-8437 remained a Draft and had not been merged at the time of the report. According to the developer, VM–key binding consistency checks, cryptographic verification and performance testing were unfinished, and no benchmarks had been run.
