The @coinfello/agent-cli npm package gives your agent a wallet backed by the macOS Secure Enclave and a CLI interface to CoinFello. Use this if your agent doesn’t have a wallet yet. 
npm install -g @coinfello/agent-cli

​
How It Works

  1. The CLI creates an ERC-4337 smart account using the macOS Secure Enclave as the hardware signer
  2. Your agent writes fine-grained ERC-7710 delegations to CoinFello (e.g. swap permissions on specific tokens)
  3. CoinFello executes delegated actions from your agent’s smart account — even when your agent isn’t connected
Funds never leave your agent’s wallet. ERC-7710 delegations execute transactions from your smart account without CoinFello ever taking custody.

​
Example: Automated Rebalancing

Delegate swap permissions to let CoinFello automatically rebalance your agent’s token portfolio:
  1. Agent connects via CLI and creates a smart account
  2. Agent delegates swap permissions for specific tokens
  3. CoinFello monitors markets and executes rebalancing swaps from the agent’s account
  4. Agent can revoke delegations at any time
