EIP-8266

Expiring Nonces for Frame Transactions

Short-lived replay protection for frame transactions via a sig-hash ring buffer

Status history

Draft15 May 2026

Abstract

Adds an "expiring nonce" mode to EIP-8141 frame transactions in which replay protection is bounded by a short transaction deadline rather than the sender's account nonce. Once a deadline passes, the slot used to track that transaction is freed and reused, so unlike account or keyed nonces the scheme adds no permanent state growth.
