ConsoleChain

ConsoleChain is a powerful command-line interface (CLI) tool for seamless interaction with smart contracts on various blockchain networks. Built with TypeScript for enhanced type safety and developer experience.

Features

• 1000+ Chains - Access any EVM chain via chainlist.org integration
• RPC Fallback System - Automatically uses backup RPCs if primary fails
• Smart Chain Selection - Simple UI showing only chain slugs
• Custom RPC Support - Use any RPC endpoint you prefer
• Secure Private Key Storage - Optional encryption for your keys
• Interactive REPL - Autocomplete, command history, and help system
• Type Safety - Built with TypeScript
• Standard Support - Built-in ABIs for ERC-20, ERC-721, and ERC-1155

Installation

Install ConsoleChain globally using npm:

npm install -g consolechain

Quick Start

Option 1: Let CLI Ask for Chain (Recommended)

Just provide the contract address - CLI will prompt you to select the chain:

consolechain 0xYourContractAddress --standard 20

# You'll be prompted:
# 🔗 Select a blockchain network
# ? Search (name, symbol, or chain ID): ethereum
# ? Select chain: ethereum

Option 2: Specify Chain by Name

consolechain 0xYourContractAddress --chain ethereum --standard 721
consolechain 0xYourContractAddress --chain polygon --standard 20
consolechain 0xYourContractAddress --chain base --abi ./abi.json

Option 3: Custom RPC URL

Use any RPC endpoint directly:

consolechain 0xYourContractAddress --rpc https://eth.llamarpc.com --standard 20

List Available Chains

# Show popular chains
consolechain list-chains

# Search for specific chains
consolechain list-chains polygon
consolechain list-chains arbitrum
consolechain list-chains 8453  # Search by chain ID

Setting Up Your Private Key

To execute transactions that modify state, set your private key:

consolechain set-pk your-private-key-here

🔒 Security Best Practice: Set the CONSOLECHAIN_ENCRYPTION_KEY environment variable to encrypt your private key:

export CONSOLECHAIN_ENCRYPTION_KEY=$(openssl rand -hex 32)
consolechain set-pk your-private-key

Interactive Console

Once connected, you have access to several features:

Autocomplete

• Press TAB to autocomplete function names
• Press TAB twice to see all available functions

Get Function Help

Ξ balanceOf -h
balanceOf(owner: address)

Call Functions

Ξ balanceOf 0x1234567890123456789012345678901234567890
  1000000000000000000

Special Commands

• help - Show available commands
• exit - Exit the console
• clear - Clear the screen

Chain Selection Examples

Interactive Selection

# Start interactive mode
consolechain 0xYourAddress --interactive --standard 721

# You'll be prompted to:
# 1. Search for a chain (e.g., "base", "polygon", "arbitrum")
# 2. Select from matching results
# 3. Automatically connects with best RPC

Direct Chain Selection

# Ethereum Mainnet
consolechain 0xAddress --chain ethereum --standard 20

# Polygon
consolechain 0xAddress --chain polygon --standard 721

# Base
consolechain 0xAddress --chain base --standard 1155

# Arbitrum
consolechain 0xAddress --chain arbitrum --abi ./MyContract.json

# Any chain by ID
consolechain 0xAddress --chain 8453 --standard 20  # Base

Custom RPC Examples

# Use a specific RPC provider
consolechain 0xAddress --rpc https://eth.llamarpc.com --standard 20

# Use your own node
consolechain 0xAddress --rpc http://localhost:8545 --abi ./abi.json

# Use a premium RPC service
consolechain 0xAddress --rpc https://mainnet.infura.io/v3/YOUR_KEY --standard 721

Examples

Interacting with USDC on Ethereum

# Using chain name
consolechain 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 --chain ethereum --standard 20

# Inside console
Ξ name
  USD Coin
Ξ symbol
  USDC
Ξ decimals
  6
Ξ totalSupply
  24835236580839861

Interacting with NFTs on Base

# Interactive mode
consolechain 0xYourNFTAddress --interactive --standard 721

# Search for "base" → Select "Base" → Auto-connects
Ξ name
Ξ ownerOf 1

Using Custom ABI

consolechain 0xCustomContract --chain arbitrum --abi ./MyContract.json
Ξ myCustomFunction arg1 arg2

Passing Complex Arguments

# Arrays
Ξ batchTransfer '["0xAddr1","0xAddr2"]' '[100,200]'

# Strings with spaces
Ξ setName 'My Token Name'

# Numbers
Ξ setValue 123456

# Booleans
Ξ setFlag true
