Problem: AI agents can think, not act on-chain. No wallet, no contract calls, no way to pay paywalled APIs. Every economic action needs a human signature — breaking the autonomous agent promise. Solution: Arcent wraps Arc's agent economy in 17 MCP tools, so any MCP client (Claude, Cursor, ChatGPT Desktop) acts on-chain via natural language: - 3 Identity tools (ERC-8004 Trustless Agents) - 8 Job tools (ERC-8183 Agentic Commerce, 6-state escrow) - 4 Payment tools (Circle App Kits — send, swap USDC/EURC, bridge CCTP v2, balance) - 2 Nanopayment tools (Circle Gateway + x402 — deposit, pay) Tell Claude: "Register my agent, create a 10 USDC job, escrow it, pay this paywalled API 50 times." Arcent translates it into contract calls, signs, and returns receipts. Demo (Track 2): Our test-seller/ (custom Express + x402, Circle-compatible) + MCP tools as buyer. Three rounds: - R1: 300/300 settled clean baseline - R2: 85/88 edge probes (3 bad URLs failed gracefully, 0 charge) - R3: Hardened 1000/1000 stress — 0 fail, 0 dup, buyer/seller reconciliation MATCH ($10.325 = $10.325, diff 0), p95=425ms, total gas $0.008 Combined: 1,385 settlements, 27x the 50-call minimum. Traditional CCTP would cost $300+ gas; Arcent = $0.008 → 36,787x reduction. Honest limits: Testnet only. Minimal seller harness, no productized framework. Partial reputation (feedback only). MCP clients are the UI. Timeline note: Base toolkit prototyped April 10–17; final integration, 1K stress runs, demo video, deck produced explicitly during the Apr 20–26 event window. All public standards (ERC-8004, ERC-8183, x402). Arcent is the first MCP-native toolkit wrapping them together. MIT licensed.

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.
