Introduction
BlueWallet is a widely trusted Bitcoin wallet app known for its user-friendly interface and support for advanced features. One key feature is its ability to connect directly to your own Bitcoin node, which significantly enhances your privacy and security.
By connecting BlueWallet to your own self-hosted Bitcoin node, you take back control of your transaction data, eliminating reliance on third-party Electrum servers. This is critical for anyone serious about protecting their financial privacy in the decentralized Bitcoin ecosystem.
Additionally, BlueWallet supports Lightning Network through LNDHub nodes, enabling seamless spot Bitcoin transactions, and future integration with lending or derivatives platforms may evolve as DeFi on Bitcoin grows.
Setting Up Your Own Bitcoin Node
Before connecting BlueWallet, you must set up and run your own Bitcoin node. Here’s a brief overview:
- Choose Hardware: Raspberry Pi, dedicated PC, or VPS with sufficient storage and uptime.
- Install Node Software: Download and install Bitcoin Core, the reference full node client.
- Sync Blockchain: Allow the node to fully sync the Bitcoin blockchain (can take hours to days).
- Enable Electrum or LNDHub Server: Run ElectrumX or Electrs to serve Electrum queries or set up LNDHub for Lightning wallet backend. See official docs: BlueWallet LNDHub guide.
Connecting BlueWallet to Your Node
Once your node and server are online:
- Open BlueWallet on your mobile device.
- Navigate to Settings > Wallet Settings > Electrum Server.
- Toggle Custom Electrum Server and input your node's IP address and port (e.g.,
192.168.1.10:50002 for Electrum SSL).
- If using Lightning via LNDHub, add your node URL in the LNDHub connection fields.
- Save and restart BlueWallet to apply changes.
This setup ensures all wallet queries for balances, UTXOs, and transactions communicate directly with your own Bitcoin node, preventing data exposure.
