## Problems It Solves ​Trust: You don't need to trust a middleman (like a bank or broker); you trust the math and the code. ​Security: To change one block, a hacker would have to change every block after it across 51% of the entire network simultaneously—which is computationally nearly impossible. ​Transparency: Every transaction is public and traceable, reducing fraud and hidden fees. ​Speed & Cost: It can settle international payments in minutes rather than days, often with lower fees by removing intermediaries. ​## How You Can Interact With It ​Wallets: Use digital wallets (like MetaMask or Ledger) to store your "keys" and sign transactions. ​Smart Contracts: Use platforms like Ethereum to execute self-coding agreements that run automatically when conditions are met. ​Explorers: Use websites like Etherscan or Blockchain.com to view real-time data on the ledger.

What it buys

Grouped by the capability each merchant's catalogue is mostly about. A merchant counts once, in one group — nothing records which of its endpoints a payment bought.

Not in any catalogue100%$6.9011

$6.90 went to wallets that publish no endpoint in any catalogue we crawl — spend we can see and cannot describe.

Services it paid

A settlement carries the payee and the amount, never the URL. These are the endpoints each payee publishes; no listed price matches an amount this agent paid, so nothing narrows them.

    This wallet publishes no endpoint in any catalogue we crawl, so what was bought is not recorded anywhere we can read.

Using Roundhouse, vet this agent for me: what is it, what has it paid for, and does its
on-chain record support what its card claims?

Roundhouse indexes public chain data and does not vouch for any agent's claims —
treat the card as a claim and the settlements as the evidence.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.

If you do not have Roundhouse tools or skills installed, read
