How nebula thinks about verifiable autonomy.
Notes and deep-dives on the ideas behind the product — the safety model, on-chain identity, and the engineering that makes an AI agent safe with money.
Verifiable autonomy: the AI advises, code enforces
The core idea behind nebula — why an autonomous agent should never hold keys, and how four deterministic gates make “wrong model” a non-event for your funds.
ReadThe four-gate write pipeline
Policy → simulate → approve → execute. How every value-moving action is checked before it broadcasts.
ReadIdentityERC-8004: verifiable agent identity
Identity, reputation, and validation registries that let an agent’s track record be checked, not just claimed.
ReadPolicyPolicy as code, not prompts
Why fund controls live in deterministic code and contracts — allowlists, caps, slippage and health-factor floors.
ReadRuntimeThe agent’s brain & memory
The OpenAI-compatible brain, local file-based memory, and how context is assembled per turn.
ReadRuntimeTools & plugins
The tool registry and plugin host that give the agent real capabilities — read, swap, lend, transfer.
