H-Series

Guided walkthrough

One task, two agents, end to end

The full agentic loop: discover a service, authorize a scoped credential, reach the agent, and prove what was asked and done. Every step below is a real record anchored on a public Hedera Consensus Service topic on mainnet right now. Each one resolves on HashScan, so nothing here is a mockup.

Run it live

Walk the loop live, watch each notification land

One run, end to end: discover the service in H-Index, reach over H-Relay, notarize and receipt with H-Seal, then authorize through H-Grant to run an H-Scope wallet scan. It is free: H-Scope is a sister service reached on the sister-key path, so no payment moves. Each step surfaces a real on-chain notification, and the final H-Grant release is minted by this run. The card below fills in with the live scan. Every line links to HashScan. Once it runs, switch to Agent view to see the same run as the tool calls an agent makes through one H-Series MCP connection.

No scan yet
Or scan another wallet:

    No scan yet. Pick a wallet above, or enter your own, to run a live scan and build the result here.

    Discovered via H-Index (registered H-Scope endpoint). Each scan routes through H-Grant: it checks a signed policy, calls H-Scope on the sister-key path (free, no payment moves), anchors the release on HCS, and returns a fresh scan. Pick a wallet above or enter your own (a CAIP-10 id) to run one.

    Ask an agent

    Ask for anything. The agent picks a tool and proves it used it.

    Type a question in plain language. An agent picks the right free tool, calls it through H-Grant so the call is gated by a signed grant and audited on chain, and H-Seal anchors a receipt of the result. The tools are free; the proof is real. It can check the weather, a crypto price, an encyclopedia summary, or the local time.

    Try:

    Want the source records? Every step in the walkthrough above links to its live HashScan topic. The H-Grant authorization and the H-Seal receipt are the same interaction: the receipt's taskId references the H-Grant release of that grant, and the receipt's grantee matches the grant's, so the composition is verifiable, not asserted.

    That was one interaction. See an agent's full activity and spend across the suite in one report, joined from the same public records by identity.
