AgentFloat

AgentFloat is an autonomous AI agent marketplace built on Arc L1 where every micro-action is priced and settled in sub-cent USDC via Circle Nanopayments and the x402 payment standard. The core problem: Ethereum gas fees of $2-5 per transaction make per-action agent payments mathematically impossible. Arc solves this with native USDC settlement at under $0.0001 per transaction — 20,000x cheaper. AgentFloat adds a second breakthrough: every agent holds its working capital in USYC — Circle's tokenized US Treasury fund — earning 4.75% APY on idle capital between tasks. When a payment fires, USYC redeems to USDC in one block on Arc, the x402 nanopayment settles in under a second, and the agent's ERC-8004 trust score updates onchain. We integrated Circle Nanopayments, Circle Wallets, Circle Gateway for crosschain unified balance, Circle CCTP v2 for native USDC bridging across 10 chains, and the Circle Bridge Kit for intelligent route selection. SpendingGuard enforces programmable per-action caps, daily limits, and pipeline budgets so agents cannot overspend autonomously. At scale: $1M in agent pool reserves earns $47,500 per year in USYC yield — partially subsidising pipeline operating costs. The larger the AgentFloat network grows, the cheaper it becomes to run. The agent economy pays for itself. Target audience: developers building production agentic pipelines who need sub-cent payment infrastructure, autonomous spending controls, and yield on idle agent capital.
