Sampan Trust checkout on NEAR

Pay only for what the buyer authorised.

A checkout that can prove every payment was what the buyer authorised. A person or an AI agent pays from another chain through NEAR Intents, and anyone can check the receipt in the browser, with no wallet and no server of ours.

A NEAR contract pays the shop only for an order inside the buyer's signed mandate, and refuses the rest. The test shop is a dry checkout preview and never pays. Load one of the receipts below in the checker.

Receipts

On testnet the checker reads "Cannot verify" for two checks, because the test gate keeps an owner key. Every other check passes. Source code, claims and audits are in the repository README.
