Intentra — ETHOnline 2026. An AI service marketplace where every payment is bound to a signed EIP-712 mandate and to on-chain evidence: a Solidity USDC escrow on Arc, AI-mediated dispute resolution, and a FastAPI orchestrator that never holds funds.
Machine-payable, cross-protocol vault-risk service. One Graph query template per schema family plus a new ERC-4626 Substreams module, sold per request over x402 on Hedera and Arc, with ML-DSA-65 signed receipts and ML-KEM sealed requests.
ETHOnline Continuity build: policy-gated Agent-to-Agent commerce with The Graph provenance, Privy authorization, and Arc USDC settlement.

Taker priority by sealed competitive bid — a custom 1inch SwapVM instruction (opcode 0x2e). Bidders commit to sealed bids; the highest bidder wins the right to fill and pays the runner-up's price, with the difference going to the maker. Live on Base.
vet402 — independent verification of the x402 agent-payment economy: it buys what endpoints actually sell, verifies fulfillment against the seller's own declaration, and publishes the results with evidence (formerly Vouch).
Keep your AI agents on a leash: bind an agent's identity, give it a governed spending account with on-chain limits, and cut it off everywhere with one write. ENS + Hedera x402 + Privy.
🔁 Renews an agent's API access on-chain: an x402-gated service on Hedera where the Hedera Schedule Service (HIP-1215, system contract 0x16b) calls the contract back at expiry, charges the next period and re-arms the next renewal. The agent pays once over x402; no user, server job or cron keeps it alive.
