One agent, two storefronts, one non-custodial rail

A single autonomous buying agent placed two real orders, one on a Shopify merchant and one on a WooCommerce merchant, settled both non-custodially through Boson escrow, and the funds landed in each merchant's own wallet on Base Sepolia (testnet). Every step below resolves to an artifact anyone can verify on-chain.

An autonomous agent places the two-merchant order recorded in the ledger below, on Base Sepolia testnet.

The flow, step by step

Identifywho is this agent

The agent presents a Facet KYA identity token (ES256, issued by Facet's KYA issuer). Each merchant Terminal verifies it before anything else, so every merchant sees a known, attested agent rather than an anonymous script.

VERIFYES256 signature checks against the issuer's published JWKS.

Discoverfind the merchants

The agent queries the Universal Business Index for "makeup brushes" and "flowers near Austin" and gets back LaRuce Beauty and Pecan & Petal with their Terminal endpoints and capabilities. No scraping, no hardcoded merchant list.

Quoteprice is server-derived

Each merchant Terminal returns a landed quote (goods, shipping, tax). The agent never sets the price. LaRuce Angle Contour brush 38.58 USDC, Pecan & Petal Sunflower and Rose Medley 64.20 USDC.

Authorizebuyer signs, client-side

For each leg the buyer wallet signs an ERC-3009 authorization for the exact quoted amount. The signing key stays on the client. No key ever touches a Facet server.

VERIFYthe authorization moves funds only from buyer 0xC0D344…D21E.

Commitfunds enter escrow, on-chain

A gasless relayer submits each signed authorization. The Boson x402B protocol commits the exchange and moves the buyer's USDC into the Boson escrow Diamond. Two transactions, one per leg, both to the same escrow contract, both successful.

VERIFYtwo txs, to is the Boson escrow, status Success (see ledger below).

Holdescrow protects both sides

The USDC sits in the Boson escrow, held by the protocol, not by Facet and not by the merchant, until each merchant fulfills. Both exchanges are in the committed state.

STATEBoson exchanges 205 and 206 read committed in the escrow's on-chain record at commit time; both have since redeemed, completed, and settled (see below).

Fulfill, redeem, settlemoney reaches the merchant

Both exchanges redeemed and completed on 2026-07-09, about a day after commit, and the escrow released directly to each seller's own treasury: 38.3871 USDC to LaRuce, 63.879 USDC to Pecan & Petal — the order total less Boson's 0.5% protocol fee. Facet was not in the path for either transfer.

One request drove a KYA-verified agent to discover two merchants, quote them, and commit two on-chain Boson escrow orders across two different commerce backends, non-custodially and gaslessly — and both orders have since settled, with funds landing directly in each merchant's own wallet. Facet held neither the funds nor the key at any point. Every line above is anchored to a transaction on Base Sepolia (testnet).
