Connect Trezor Suite to Your Own Node

Introduction

In this guide we explain how to connect the Trezor Suite desktop application to your own blockchain node. By doing so, you gain full control over the backend infrastructure: you verify balances and transactions using your own node rather than relying on third‑party services. This approach enhances your privacy, trust and self‑sovereignty.

Why Use Your Own Node?

The default setup for Trezor Suite is to connect to backend servers operated by the manufacturer. While those servers are reliable and privacy‑respecting, running your own node takes things further. You avoid relying on someone else’s infrastructure, reduce external dependencies, and ensure that your wallet queries go directly through your own server.

Running your own node means verifying the blockchain yourself, indexing it, and maintaining the backend backend server (for example using Blockbook or Electrum server). This gives you stronger assurance that your transaction history and balances are directly derived from your own node.

Prerequisites

Before you configure Trezor Suite to use your own node, make sure you have:

A fully synced and reachable node (for example a Bitcoin full node with correct block height).
A supported backend server: for Bitcoin you may use a custom Electrum server or a custom Blockbook server for supported coins.
The Trezor device connected and unlocked, and Trezor Suite installed on your desktop (not web or mobile version since custom backends are only supported in desktop version).

Step‑by‑Step: How to Configure

Open Trezor Suite on your desktop, then go to Settings → Coins. Hover over the coin you want to connect your node for (e.g., Bitcoin) and click the gear icon. Under “Backend” choose either Custom Blockbook server or Custom Electrum server (for Bitcoin only). Then input the server address as per your node’s specification:

    Example Blockbook URL: http://localhost:9130  
    Example Electrum format: 192.168.1.100:50002:s

After entering the address, confirm and exit settings. You will see an icon in the top‑bar indicating backend status. Ensure it shows connected and that your transactions and balances load properly.

Best Practices & Tips

• Use a secure and stable node setup (cold hardware, reliable connectivity).
• If using an Electrum server over Tor, you may supply an onion address and ensure your suite has Tor enabled.
• Always verify your node remains synced and accessible before trusting it for wallet operations.
• Keep your device firmware and Trezor Suite app up‑to‑date.
• Periodically check the backend icon in the user interface to detect any disconnection issues early.

Conclusion

Configuring Trezor Suite to use your own node is a powerful step towards full self‑custody and privacy. By routing your wallet’s backend traffic through infrastructure you control, you eliminate reliance on external servers and expose fewer data points to third parties. While it takes a bit of setup and maintenance, the rewards in terms of security and sovereignty are meaningful.
