Vitalik Buterin Proposes Unified Shared Sequencer Interface for Ethereum L2s

Vitalik Buterin proposes ERC-7702 for shared sequencers on Ethereum Layer 2 networks. The interface enables autonomous agents to interact with compliant shared sequencers without chain-specific integration. Key features include gas-predictable submission, explicit error codes, and slashing event signatures. The standard aims to address fragmentation in the space and provide a clean interface for tooling developers.
