Transfer

Learn how to transfer agent ownership to another address using the Agent0 SDK.

Agent transfer allows the current owner of an agent to transfer ownership to a new address. This is useful for:

• Selling agents: Transfer ownership when selling an agent to another party
• Team handoffs: Transfer agents between team members or departments
• Account management: Move agents to different wallets for organizational purposes
• Escrow scenarios: Transfer agents as part of contractual agreements

Prerequisites

Before transferring an agent, ensure you have:

1. Agent ownership: You must be the current owner of the agent
2. Valid recipient address: The new owner must have a valid Ethereum address
3. Sufficient gas: Transaction fees are required for the transfer
4. Network access: Connection to the blockchain network where the agent is registered

Transfer Agent

Python

from agent0_sdk import SDK

# Initialize SDK
sdk = SDK(
    chainId=11155111,
    rpcUrl="https://sepolia.infura.io/v3/YOUR_PROJECT_ID",
    signer=your_private_key
)

# Load the agent
agent = sdk.loadAgent("11155111:123")

# Transfer to new owner
new_owner = "0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6"
transfer_result = agent.transfer(new_owner)

print(f"Transfer successful: {transfer_result['txHash']}")

TypeScript

import { SDK } from 'agent0-sdk';

// Initialize SDK
const sdk = new SDK({
  chainId: 11155111,
  rpcUrl: 'https://sepolia.infura.io/v3/YOUR_PROJECT_ID',
  signer: yourPrivateKey,
});

// Load the agent (async in TypeScript)
const agent = await sdk.loadAgent('11155111:123');

// Transfer to new owner (async in TypeScript)
const newOwner = '0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6';
const transferResult = await agent.transfer(newOwner);

console.log(`Transfer successful: ${transferResult.txHash}`);
console.log(`From: ${transferResult.from}`);
console.log(`To: ${transferResult.to}`);
console.log(`Agent ID: ${transferResult.agentId}`);

isAgentOwner Utility Function

The isAgentOwner() utility function provides a convenient way to check if the current SDK signer owns a specific agent:

Python

# Check if you own an agent
is_owner = sdk.isAgentOwner("11155111:123")

if is_owner:
    print("You own this agent and can transfer it")
else:
    print("You do not own this agent")

TypeScript

// Check if you own an agent (async in TypeScript)
const isOwner = await sdk.isAgentOwner('11155111:123');

if (isOwner) {
  console.log('You own this agent and can transfer it');
} else {
  console.log('You do not own this agent');
}

What it does:

• Queries the IdentityRegistry contract for the agent’s current owner
• Compares it with the SDK’s configured signer address
• Returns True if the signer is the owner, False otherwise
• Handles address normalization (case-insensitive comparison)

Use cases:

• Verify ownership before attempting transfers
• Check permissions before making agent modifications
• Validate access rights in multi-user applications
• Implement access control in agent management interfaces
