SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Interact with CoinFello using the @coinfello/agent-cli to create a smart account, sign in with SIWE, manage delegations, send prompts with server-driven ERC-20 token subdelegations, and check transaction status. Use when the user wants to send crypto transactions via natural language prompts, manage smart account delegations, or check CoinFello transaction results.

Core Features & Use Cases

  • Create and manage a CoinFello smart account via CLI
  • Sign-In with Ethereum (SIWE) and delegation workflows
  • Send natural-language prompts to trigger on-chain actions and view transaction status
  • Handle server-driven delegation requests with review and approval flows
  • Works with multiple supported networks (Ethereum, Optimism, BSC, Polygon, Base, Arbitrum, Linea, Sepolia, Base Sepolia)

Quick Start

Run npx @coinfello/agent-cli@latest to create a smart account, sign in with SIWE, and start managing delegations.

FAQPage Schema
How do I manage smart account delegations using a CLI?

You can manage smart account delegations using a CLI by running the @coinfello/agent-cli tool, which handles server-driven delegation requests, ERC-20 token subdelegations, and secure local configuration storage automatically.

Can I send blockchain transactions using natural language prompts?

Yes, you can send blockchain transactions using natural language prompts through the CoinFello agent CLI, which translates your text input into on-chain actions and subsequently tracks the transaction status across supported networks.

Does the CoinFello agent CLI support Ethereum, Optimism, and Polygon networks?

The CoinFello agent CLI supports Ethereum, Optimism, BSC, Polygon, Base, Arbitrum, Linea, Sepolia, and Base Sepolia networks. It enforces supported chains to ensure transactions and smart account operations execute correctly.

How do I set up Sign-In with Ethereum (SIWE) for a smart account?

To set up Sign-In with Ethereum (SIWE) for a smart account, run npx @coinfello/agent-cli@latest. This initializes the CLI workflow to create your smart account, execute the SIWE authentication flow, and start managing delegations.

What is the best way to handle server-driven delegation requests for crypto transactions?

The best way to handle server-driven delegation requests for crypto transactions is using the CoinFello agent CLI, which provides built-in review and approval flows to securely manage ERC-20 token subdelegations triggered by natural language prompts.

Why should I use a CLI tool for smart account management instead of manual signing?

Using a CLI tool for smart account management automates SIWE flows, delegation tracking, and transaction status checks. It stores configuration securely in a local config, reducing manual signing errors while managing on-chain actions across multiple networks.
