Protocol Labs Unveils EIP-7702 for Onchain Token Metadata Storage

Here's the expanded 60-word summary: Protocol Labs introduces new EIP-7702 for storing arbitrary metadata onchain, covering ERC-721, ERC-1155, ERC-6909, and ERC-8004 registries. Key features include a key-value pair interface and required `getMetadata()` function. Backwards compatible with existing token standards, it enables trustless AI agents and custom metadata storage without gas inefficiencies. Reintroduced as a standalone standard after pivoting from ERC-8041 in September 2025.
