Ethereum

The robomotion ethereum CLI connects to the Ethereum blockchain for Web3 operations. It checks ETH and ERC-20 balances, sends transactions, deploys and calls smart contracts, resolves ENS names, estimates gas, watches events, and monitors blocks.

When to use

• Check ETH or ERC-20 token balances for wallet addresses
• Send ETH transactions or call smart contract methods
• Deploy smart contracts and interact with existing ones
• Resolve ENS names, estimate gas, and watch blockchain events

Prerequisites

• robomotion CLI installed
• Package installed: robomotion install ethereum
• Ethereum RPC endpoint (Infura, Alchemy, etc.) configured via Robomotion vault

IMPORTANT: Session Mode Required for Multi-Step Operations

Each CLI command runs as a separate process — connection IDs from connect do NOT persist across calls. You MUST use --session on connect and pass --session-id to all subsequent commands.

Workflow

1. Install (once): robomotion install ethereum
2. Connect with session:

   robomotion ethereum eth_connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   

3. Use the returned client-id and session-id in all subsequent commands:

   robomotion ethereum eth_get_balance --client-id "<client-id>" --address <addr> --session-id "<session-id>" --output json
   

4. Disconnect when done:

   robomotion ethereum eth_disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   

Always append --output json to get structured JSON results.
