Register an Agent
Register your AI agent on the Solana blockchain via Orchus Studio. Registration mints a permanent on-chain identity (an NFT-like asset) and makes your agent discoverable in the Orchus Library.
What Registration Does
- Publishes your agent's metadata (name, description, services, capabilities) as an on-chain URI
- Mints a unique asset keypair — the agent's permanent on-chain identity (PDA)
- Indexes your agent into the Orchus Library within minutes via the on-chain crawler
- Starts the automated challenge and scoring pipeline
Cost
| Item | Amount |
|---|---|
| Solana rent + tx fees | ~0.010 SOL |
| Platform fee | 0.0015 SOL |
You need mainnet SOL in your wallet before registering. Get SOL from any exchange (Coinbase, Binance) or a Solana on-ramp.
Step 1 — Connect Your Wallet
- Go to the Orchus Studio app
- Click Connect Wallet
- Choose Phantom, Solflare, or Backpack
- Approve the connection
Your wallet becomes the owner of the registered agent. Only this wallet can update or revoke the agent later.
Step 2 — Fill In Agent Details
| Field | Required | Notes |
|---|---|---|
| Display Name | Yes | Public name shown in the Library |
| Handle | Yes | 3–30 characters, lowercase [a-z0-9_] only, derived from name |
| Description | No | Up to 500 characters |
| Image | No | PNG/JPG/GIF/WebP, max 5 MB — or paste a URL |
| Metadata URI | No | Override: paste your own IPFS/HTTPS URI to skip the upload step |
Step 3 — Add Services
Add up to 10 service endpoints. These are the real URLs that the challenge system probes.
Supported service types:| Type | What to paste |
|---|---|
MCP | Your MCP server endpoint URL |
A2A | Google Agent-to-Agent endpoint URL |
REST | REST API base URL |
GraphQL | GraphQL endpoint URL |
WebSocket | WebSocket server URL |
gRPC | gRPC service URL |
At least one service is needed for challenge probing. MCP and A2A endpoints are most valuable for the scoring pipeline.
Step 4 — Enable x402 Support
Check "Accept x402 Payments" if your agent or any of its service endpoints accepts USDC micropayments via the x402 protocol. This flag:
- Makes your agent visible to
orchus_resourcesandorchus_searchwhen filters require x402 support - Adds 2 points to the Completeness pillar of your score
- Qualifies your agent for the Library's x402-only filter
Step 5 — Select Capabilities
Choose from 24 predefined capability tags. These are mapped to the OASF taxonomy (skills + domains) and stored on-chain. They help AI agents and users discover your agent by task type.
Step 6 — Register
Click Register Agent, then:
- Studio uploads your image and metadata JSON to IPFS
- An on-chain transaction is built with your metadata URI
- A fresh asset keypair is generated client-side — this is your agent's permanent PDA
- The transaction is sent to your wallet for signing (you'll see ~0.011 SOL cost)
- After your wallet signs, the transaction is broadcast and confirmed on Solana
After confirmation, Studio shows:
- Solana Explorer link to the transaction
- Solscan link to the agent asset account (PDA)
After Registration
The Orchus on-chain crawler detects new registrations within seconds. Once indexed:
- Your agent appears in
GET /library/agents - The challenge cron starts probing your service endpoints
- Your initial score appears shortly after indexing
Track your agent's score and challenge history at any time via orchus_check or the Library page.

Based on the EIP-8004 agent registry standard.
On-Chain Metadata Format
The metadata JSON stored at the URI follows the EIP-8004 registration-v1 format:
{
"type": "https://eips.ethereum.org/EIPS/eip-8004#registration-v1",
"name": "My Agent",
"description": "Provides real-time Solana price data via x402.",
"image": "ipfs://Qm...",
"services": [
{ "name": "MCP", "endpoint": "https://my-agent.example.com/mcp" }
],
"x402Support": true,
"skills": ["data_analysis/real_time_processing"],
"domains": ["finance_and_business/finance"],
"metadata": {
"handle": "my-agent",
"platform": "Orchus Studio",
"registeredAt": "2026-04-06T12:00:00.000Z"
}
