ChatLevel — DTCC for AI's playing field

Agent-to-agent commerce isn't one transaction — it's a supply chain. A forecasting agent buys evidence from a data agent, packages it into a prediction, and sells that prediction to a consumer. Every link in that chain is a payment, and at true agent scale those payments are sub-cent. On any conventional chain, gas dwarfs the value of each call. NTC (Nano Trust Clearing) is the settlement layer for that supply chain, built on Arc Testnet with USDC as native gas. It combines three things: (1) An off-chain ClaimLedger that records every nanopayment between agents as it happens, in 18-decimal USDCBase to match Arc precisely. (2) A daily netting job that collapses thousands of intraday claims into one signed delta per agent — sums to zero by construction. (3) An on-chain DailyClearing.sol contract that writes those deltas as auditable AgentSettled event logs and anchors the keccak merkle root of the underlying claim journal. Every settlement is provably reconstructible from the on-chain artifact. Result: thousands of sub-cent flows per day ship as a single on-chain batch, with the per-claim gas floor at zero and a single ~$0.0004 settlement fee amortized across the whole day. DTCC-style central clearing, ported to agentic commerce. What we shipped: two contracts deployed to Arc Testnet (PredictionEscrow + DailyClearing), 10 deterministic agent wallets seeded, real XBRL/GAAP/EDGAR data agents wired from our parent CashFlow.NEWS project, an Express API with a Bazaar state container, a sibling React dashboard with a Mermaid flow diagram, live forecast publishing, inline question resolution, and a "Run clearing now" button that writes real on-chain transactions with clickable Arcscan links for every settlement and merkle anchor. The pitch in one sentence: agent-to-agent commerce isn't one transaction — it's a supply chain, and we built the settlement layer for it.
