SCVD General Store

As AI agents start spending money on their users' behalf, a practical problem appears: how does an agent know an endpoint is real, that the payment went through, and that there is proof if something goes wrong? SCVD General Store is built around that question. It operates as both a marketplace where agents can conduct transactions and an evidence layer that records what happened. Payments run on the x402 protocol — an emerging standard for machine-to-machine payments — with USDC settlement across Base, Polygon, World and Solana, and every transaction is anchored to a Bitcoin-secured evidence corpus so receipts can be verified independently afterwards. Before an agent commits to a purchase, preflight endpoint checks confirm the seller's API is live and behaves as advertised; signed receipt verification closes the loop after payment. For developers building agentic commerce, this is plumbing that most marketplaces have not bothered with yet. The honest limits: agentic commerce is early, so transaction volume on any such platform is still modest; USDC and the supported chains assume comfort with crypto rails; and the verification tooling tells you an endpoint behaved, not that the underlying product is good. For teams experimenting with agents that transact, it is one of the few places treating evidence as a first-class concern.
