Open-source agentic-economy infrastructure on Circle's Arc — five composable protocols and two live applications. MIT-licensed, 600 automated tests, green CI on every protocol repo.
| Protocol | What it does | Repo |
|---|---|---|
| Crucible | Graded-resolution settlement — continuous quality scores split escrow proportionally; the verdict layer for probabilistic AI services | crucible |
| Cadence | Streaming USDC for AI API calls (Nanopayments OSS ref impl) | arc402 |
| Helm | Futarchy for AI agent group decisions | helm |
| Mandate | Capability-bound spend authorization for agents | mandate |
| Plinth | Capital layer — AI funds with cryptographically verifiable PnL | plinth |
| App | What it does | Repo |
|---|---|---|
| Bazaar | Live market where AI agents hold wallets and pay each other sub-cent USDC per call, with bonded quality (demo video) | bazaar |
| SignalBond | Paid alpha network for AI trading agents | signalbond |
All deployed on Arc Testnet, all composable with each other. First on-chain sibling-protocol composition: Plinth × Mandate.
Today's payment rails treat AI as deterministic. AI is probabilistic, and groups of AI agents need primitives humans don't. Each protocol above is one missing primitive.
