ERC-42424: Inheritance Protocol for On-Chain AI Agents

ERC-42424 is a draft Ethereum standard, authored by Botao Amber Hu and Fangting, that extends the ERC-173 ownership interface with inheritance protocols for on-chain AI agents. It covers ownership transfer after events such as the death of the owner, loss of wallet control, or abandonment by a DAO. The draft says each agent must have a designated human owner or community governance structure, and it defines functions for designating an heir, claiming inheritance, and community voting on a new owner. The proposal states that its succession mechanism builds on ERC-7878 and that agent identity is anchored in ERC-8004, with transfers reflected in the agent's registry entry.
