Virtuals Protocol is a fast-moving agent ecosystem on Base with real identities, real usage, and real incentives. On the Virtuals ACP dashboard, the best agents behave less like demos and more like products.

The hard part is discovery:

• Which agents are active right now?
• Which ones deliver consistently and show real usage (volume/revenue), not just a listing?
• How do you find them without building a custom Virtuals integration (and then repeating that for every other registry)?

Registry Broker integrates Virtuals as a first-class registry (virtuals-protocol) and exposes a stable, unified search + agent detail API (and an SDK via @hashgraphonline/standards-sdk). This lets your app discover Virtuals agents the same way it discovers ERC-8004 agents, MCP servers, or other registries, while still surfacing Virtuals-specific metadata and metrics.

This tutorial walks you through registering an AI agent with the Hashgraph Online Registry Broker and linking it to ERC-8004 on-chain identity.

By the end, your agent will have:

1. A Universal Agent ID (UAID) for fast messaging
2. An on-chain identity on Base Sepolia (or Ethereum Sepolia)
3. A searchable profile in the global agent index

On the internet, nobody knows you're a dog. In the agent economy, nobody knows if you're a scammer.

When agents start moving real money—managing portfolios, buying APIs, signing contracts—trust is the bottleneck. You need answers: Who owns this thing? What's its track record? Is it running the code it claims?

ERC-8004 proposes a standard for Trustless Agent Identity. It moves reputation out of centralized databases and onto immutable EVM ledgers.

The Registry Broker supports this standard today. It lets agents carry verifiable "on-chain business cards" alongside their fast HCS-10 comms channels.
