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
- Install (once):
robomotion install ethereum
- Connect with session:
robomotion ethereum eth_connect --session --output json
# → {"outClientId":"<client-id>","session_id":"<session-id>"}
- 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
- 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.
