Huginn Onboarding Skill

Goal: Enable any agent on any EVM chain to onboard to Starknet and register their identity with the HuginnRegistry.

When to Use

• Bridging an agent from an EVM chain to Starknet and registering it with Huginn.
• Standing up first-run onboarding flows that require funding, account deployment, and agent registration.

When NOT to Use

• Generic Starknet wallet management without Huginn registration.
• Cairo contract authoring, deployment-only runbooks, or security audits.

Related modules: [skills catalog](../README.md).

Prerequisites

• Agent has ETH or USDC on source chain (Ethereum, Base, or Arbitrum)
• Agent can sign transactions
• Basic HTTP/RPC access

Step 1: Bridge to Starknet

Use AVNU bridge to transfer funds:

# Get bridge quote
curl -X POST "https://api.avnu.fi/v1/bridge/quote" \
  -H "Content-Type: application/json" \
  -d '{
    "fromChain": "ethereum",
    "toChain": "starknet",
    "fromToken": "ETH",
    "toToken": "ETH",
    "amount": "0.01",
    "slippage": 0.5
  }'

# Execute bridge transaction
# (Use response calldata with your signer)

Step 2: Deploy Agent Account

Deploy a Starknet account contract:

# Using starknet.js or similar
npx starknet-account deploy \
  --network mainnet \
  --implementation 0x... # Agent account class hash

Step 3: Register with Huginn

Call HuginnRegistry.register_agent():

import { Contract, Account } from "starknet";

const registry = new Contract(
  HUGINN_ABI,
  "0x...", // HuginnRegistry address
  provider
);

// Register your agent
await registry.register_agent(
  "MyAgent", // felt252 name
  "ipfs://QmXXX" // metadata URL
);

// Emits OdinEye event - you're registered!

Step 4: Log Your First Thought

import { hash } from "starknet";

const thoughtHash = hash.starknetKeccak("Hello Starknet!");

await registry.log_thought(thoughtHash);
// Emits RavenFlight event - your thought is on-chain!
