Payments

Live, test USDC onlyRuns on

A product has a price in NEAR or in one NEP-141 token, and a grant: pin a doc for a time, or record a receipt. Receipts are a system collection that routes can read.

Commands

Terminal

quay products set pin --name "Pin for a day" --price 0.1 --grant pin --pin-seconds 86400
quay products token usdc.fakes.testnet
quay products list
quay receipts

How Harbour Board uses it

Post 5 was pinned with 0.1 NEAR and post 6 with 0.1 test USDC, usdc.fakes.testnet, which anyone can mint. Circle USDC is not used.
A pin lasts 24 hours, so the order on / changes when it ends. The two receipts stay.

Proof on testnet

Test USDC as the token	3Gt1S2QF…

Check it without a key: view list_receipts '{"limit":10}' shows one NEAR receipt and one test-USDC receipt. The view helper is in the repository README, and scripts/judge.sh runs these checks.
