Need a new chain or feature? Open an issue or fund it via a donation to ship it faster!

Quick Start

1. Install the community node.
2. Add credentials: RPC URL + private key.
3. Drop an “EVM → Get Balance” node into any workflow.
4. Run the workflow—done!

Event Listener

Monitor blockchain events easily:

• Track token transfers, swaps, or other contract activity
• Query historical data or set up real-time monitoring
• Filter events by parameter values
• Integrate with n8n workflows for automated actions

How to Use: Monitoring USDC Transfers

This example sets up a workflow to monitor USDC token transfers on Ethereum from a specific address.

Workflow Overview

1. Schedule Trigger: Runs every 5 minutes.
2. EVM Node: Queries USDC Transfer events.
3. Filter Node: Filters transfers from a specific address.
4. Set Node: Formats the output.

Steps

1. Add Schedule Trigger:
   • Set to run every 5 minutes.
2. Configure EVM Event Listener:
   • Add an EVM node, select Contract Event Listener.
   • Settings:
     • Contract Address: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 (USDC on Ethereum).
     • Contract ABI: Copy from Etherscan.
     • Event Name: Transfer.
     • Block Range: "Recent Blocks" (set to 10 blocks).
     • Output Format: "Detailed".
     • Event Limit: 50.
3. Filter Transfers by Address:
   • Add a Filter
   • {"from": "0x123...7890","to":"0x345...122}

Workflow Structure

[Schedule Trigger] → [EVM: Event Listener] → [Filter] → [Set]

Tips

• Use a reliable RPC provider to avoid rate limits.
• Test with a larger block range if no events appear.
• Adjust block range and frequency for high-activity tokens.

Installation

Follow the official n8n guide for community nodes:

Important Disclaimer

This is an open-source, community-driven project. The code is transparent and publicly auditable. Private keys are hashed and stored securely via n8n's credential system on your own server—we never access or store your keys. Always verify the code and use minimal funds for testing. Do not use large amounts of funds in workflows without thorough testing. Use at your own risk.
