AI components need verifiable edges

The through-line is infrastructure for systems that act under constraint: wallets, markets, and agents. The interesting part is not just adding AI to products. It is making the AI layer inspectable enough to trust with real authority.

agent-architecture.trace
01. Inspectable orchestration
Model routing should expose policy, trace, cost, context, and replay hooks instead of hiding the conductor.
02. Memory with provenance
Durable agent memory needs raw records, boundary anchors, compressed gist, and reversible maintenance policy.
03. Bounded authority
Useful agents need enforceable scopes: what they can spend, erase, promote, sign, or delegate.

Smart Wallets

Passkey signing, modular accounts, ownership standards, and safer account abstraction surfaces.

ERC-7579 / ERC-7978

Market Infrastructure

Settlement, attestations, prediction-market flows, and interfaces between regulated and onchain systems.

Gemini

Agent Systems

Inspectable memory, routing, authority, and audit trails for AI tools that act on behalf of people.
