Connecting Ledger Wallet to BTCPay Server

This document shows how to connect Ledger Nano S Wallet to BTCPay Server.

Ledger Nano S Wallet Setup

This guide assumes, you have a Nano S wallet set up. To configure the Nano S, please see the quick setup guide on manufacturer's website.

Requirements

  2. Google Chrome or Firefox
  3. For Firefox, U2F needs to be enabled in about:config

  2. Open the Bitcoin app on your Ledger.
  3. In BTCPay Server, Store Settings > General > Derivation Scheme > Import from Hardware Device > Ledger wallet

  5. Confirm the Export public key on the wallet.
  6. The xpubkey will now automatically be added from Ledger to your BTCPay Server Store.
  7. Make sure that the derivation scheme is Enabled
  8. Click Continue
  9. Confirm the address match in BTCPay.

Your Ledger wallet is now connected to your BTCPay. Payments go directly to Ledger.

Manual Setup

If you have more than 20 accounts in your Ledger you might not be able to find the correct account because the select shows a maximum of 20 entries.

  1. Open the Ledger live app
  2. Accounts -> choose your account
  3. Edit Account on the top right via the tool-icon
  4. In Edit Account -> ADVANCED LOGS
  5. Copy the xpub string
  6. Paste it manually into the "DerivationScheme" textfield
