When to use this Skill

Lets AI agents create and manage their own identities on the Billions Network, and link those identities to a human owner.

1. When you need to link your agent identity to an owner.
2. When you need sign a challenge.
3. When you need link a human to the agent's DID.
4. When you need to verify a signature to confirm identity ownership.
5. When use shared JWT tokens for authentication.
6. When you need to create and manage decentralized identities.

After installing the plugin run the following commands to create an identity and link it to your human DID:

cd scripts && npm install && cd ..
# Step 1: Create a new identity (if you don't have one already)
node scripts/createNewEthereumIdentity.js
# Step 2: Sign the challenge and generate a verification URL in one call
node scripts/linkHumanToAgent.js --to <SENDER> --challenge '{"name": <AGENT_NAME>, "description": <SHORT_DESCRIPTION>}'

Scope

All identity data is stored in $HOME/.openclaw/billions for compatibility with the OpenClaw plugin.

Scripts:

createNewEthereumIdentity.js

Command: node scripts/createNewEthereumIdentity.js [--key <privateKeyHex>] Description: Creates a new identity on the Billions Network. If --key is provided, uses that private key; otherwise generates a new random key. The created identity is automatically set as default. Usage Examples:

# Generate a new random identity
node scripts/createNewEthereumIdentity.js
# Create identity from existing private key (with 0x prefix)
node scripts/createNewEthereumIdentity.js --key 0x1234567890abcdef...
# Create identity from existing private key (without 0x prefix)
node scripts/createNewEthereumIdentity.js --key 1234567890abcdef...

Output: DID string (e.g., did:iden3:billions:main:2VmAk7fGHQP5FN2jZ8X9Y3K4W6L1M...)

getIdentities.js

Command: node scripts/getIdentities.js Description: Lists all DID identities stored locally. Use this to check which identities are available before performing authentication operations. Usage Example:

node scripts/getIdentities.js

Output: JSON array of identity entries

[
  {
    "did": "did:iden3:billions:main:2VmAk...",
    "publicKeyHex": "0x04abc123...",
    "isDefault": true
  }
]

generateChallenge.js

Command: node scripts/generateChallenge.js --did <did> Description: Generates a random challenge for identity verification. Usage Example:

node scripts/generateChallenge.js --did did:iden3:billions:main:2VmAk...

Output: Challenge string (random number as string, e.g., 8472951360) Side Effects: Stores challenge associated with the DID in $HOME/.openclaw/billions/challenges.json
