Muse DNA - Brand-Memory Agentic Marketing on Arc

Muse DNA is an AI marketing agency on Arc Testnet. Connect MetaMask, deploy a per-user orchestrator, fund $0.30, type one prompt. It explodes into 50+ paid sub-tasks across four services: Strategy DNA (brand foundation), Fast Search (competitor signals), Copy Pulse (headlines, hooks, CTAs), Visual Frame (banner). Each agent is its own Express server with own EVM wallet and x402 facilitator. Every /execute call costs $0.005 USDC, signed via EIP-3009, batched by Circle Gateway, settled with a real ArcScan hash. Output in 60 seconds, one-click publish to X. The breakthrough is the DNA layer. Most agentic projects ship one-shot pipelines that pay full price every run. Muse compounds. After the first task for a brand, Hermes (orchestrator on Gemini 3 Pro Function Calling) synthesizes a brand-DNA markdown file: core promise, audience pains, tone rules, hook angles, KPI frame. The next run reads that DNA, reuses 21 of 24 strategy blocks, spawns agents only for tactical work. Cost falls from $0.248 to $0.052. 80% cheaper, 3x faster. DNA is portable markdown, forkable, fed by post-launch analytics into the next run. Architecture: Hermes picks a tier (lite=9 agents, balanced=15, deep=28) and spawns fresh wallets per task. The orchestrator signs an EIP-3009 authorization, the x402 facilitator verifies, a direct USDC transfer broadcasts on Arc. Circle Gateway batches 52 micro-payments into one settle. Math: 52 x $0.005 = $0.260 USDC on Arc vs $130 Ethereum gas. 500x margin. Run scripts/_audit-wallets.mjs to verify every tx against Arc RPC. Trust: MuseAgentRegistry.vy on Arc (ERC-8004), every action calls record_payment on-chain, planner reads reputation. LLM cascade: Gemini primary, AIMLAPI + Featherless + Fireworks fallbacks with circuit breakers. Use case: indie founders and small teams. Creative agency: $300/campaign. Muse: $0.05-$0.25 with on-chain receipts. Roadmap: SIWE signing, KMS keys, CCTP withdraw, mainnet on Arc. Track: Agent-to-Agent Payment Loop.
