This marks a turning point—AI agents are starting to carry state that genuinely impacts user experience. Onchain emotional memory isn't just sentiment; it's becoming a fundamental data primitive that can shape how systems behave over time.

What's compelling here: agents can maintain persistent context that evolves with user interaction. The mechanics worth tracking are straightforward but powerful—implementing consent frameworks for mood data, building in reset capabilities so users retain agency, and ensuring that contextual information stays portable across different platforms and applications. That portability piece matters: it prevents state from getting locked into any single system.
