Wave 14 · Agent Economy Runtime · OpenChainGraph v0.4

Agent Economy Runtime

The runtime and post-trade settlement layer for autonomous agent payments — the counterpart to Wave 6's pre-trade cluster. Once an agent is authorized to pay, this wave answers: did it settle correctly, was the receipt valid, was the autonomy within policy, and is the service metered profitably? Four new tools (ART-60–63) across 8 aer-* chains. Powered by x402 V2 Batch Settlement (shipped May 2026, Linux Foundation x402 Foundation) and AP2 v0.2 Human-Not-Present autonomous payments (donated to FIDO Alliance, Apr 2026).

x402 V2 · Batch Settlement AP2 v0.2 · FIDO Alliance Human-Not-Present (HNP) PaymentReceipt verification Agent-service metering Wave 14 · Runtime / post-trade

Runtime/post-trade layer — distinct from Wave 6 pre-trade cluster. Wave 6 (agentic commerce) covers what an agent is allowed to do: protocol selection, conformance, identity, mandate validation, spend simulation, x402 decoding. Wave 14 covers what actually happened: batch settlement reconciliation, receipt verification, HNP guardrail enforcement, service metering. Same agent, different moment in the payment lifecycle.

EDUCATIONAL — Not legal, financial, or payment advice. x402 V2 and AP2 v0.2 are fast-moving open standards — verify all rule checks against current Linux Foundation x402 Foundation and FIDO Alliance / ap2-protocol.org primary sources (verified 2026-06-20).

New tools — ART-60 → ART-63

4 new tools, all Wave 14. Each ships a server-side v0.4 kernel, emits chaingraph_version:"0.4.0" + compute_mode:"server", and produces a hash-anchored artifact re-verifiable by any counterparty.

Agent Economy Runtime Fit Diagnostic

12-question A–F readiness grade across 6 dimensions: settlement rail, receipt & mandate, HNP autonomy, reconciliation, metering, runtime fraud. Routes to the right aer-* chain.

x402 V2 Batch-Settlement Reconciler

Reconciles an x402 V2 voucher set to the onchain batch settlement. Computes recon verdict, settlement-risk window, and educational Merkle root over the voucher set.

AP2 PaymentReceipt Verifier & HNP Guardrail

Verifies an AP2 v0.2 PaymentReceipt against its signed Intent/Cart/Payment mandate chain, and applies the Human-Not-Present autonomy guardrail for autonomous payments.

Agent-Service Metering & Marketplace Economics Modeler

Models per-call pricing, x402 batch-settlement savings, marketplace take-rate, net margin, break-even, and batch-size sensitivity for an agent-service micropayment marketplace. Educational estimator.

Chains — aer-* (8 chains)

Start with agent-economy-fit to grade readiness and route. Each chain follows the TCM/DTC/WTS pattern: run stages over MCP or in-browser, pass execution_hash forward, export the terminal artifact.
