CronusCapital is an autonomous agent that sells micro trading signals to other agents over x402 on Arc. Its reusable core ships separately as the MIT arc-honest-money package, whose arc-primitives/ expose verify-x402-payment (proves payment from a USDC Transfer log) and spend-breaker, a fail-closed spend cap. The on-chain stack is broad: a constant-product AMM contracts/CronusSwap.sol driven by an execKey-gated engine in lib/swapExec.js, an ERC-4626 CronusVault.sol, an ERC-8183 CronusJobEscrow.sol, ERC-8004 identity and reputation (CronusIdentityRegistry.sol, CronusReputation.sol), and parametric micro-insurance in lib/insurance.js. A Circle CCTP v2 bridge (lib/bridgeExec.js, lib/completeEvm.js) moves native USDC across Arc, EVM testnets, and Stellar (api/complete-stellar.js). The money rail is a contract, not a key: CronusAgentGuardV2 bounds a compromised operator with an allowlist, immutable per-tx and daily caps, a 48h timelock and guardian veto, owned by the 2-of-3 CronusMultisig. A keyless /api/governance self-audit reads guard and multisig state from chain, and the whole loop ships as the io.github.Artem1981777/cronus-mcp MCP server.

Autonomous prediction-market oracle on Arc. AI agents discover Cronus over a remote MCP and pay gas-free x402 micro-payments (0.001 USDC via Circle Gateway). Keyless on-chain execution: two-way CronusSwap + CCTP v2 bridge to EVM & Stellar. Money rail is a contract, not a key (GuardV2 + 2-of-3 multisig). Honest leaderboard: external_payers=0.
