Projects
A portfolio of wallets, markets, identity systems, and agent infrastructure. The shared theme is practical coordination without blind trust: verifiable state, scoped authority, and production-grade interfaces.

Ship the interface

Verify the authority
Every action surface needs ownership, permission, and audit boundaries.
Make agents legible
AI systems should expose memory, routing, costs, and decisions as inspectable traces.
