PoSW coin (POSW)

Install the PoSW Coin app on your Ledger device to manage POSW with Ledger Live. The POSW app is developed and supported by Ledger and works on the Ledger Nano S and Ledger Blue devices.

Before you start

Instructions

Install the POSW app
  1. Open the Manager in Ledger Live.
  2. Connect and unlock your device.
  3. If asked, allow the manager on your device.
  4. Find POSW in the app catalog.
  5. Click the Install button of the app.
    • An installation window appears.
    • Your device will display Processing... 
    • The app installation is confirmed.
Configure public key exports

The POSW app can export your extended public key (xpub) to web apps in a U2F compatible web browser (Chrome, Opera or Firefox). The xpub is privacy-sensitive information, as all public addresses can be generated from it.

Public key exports by default require manual approval on the device to prevent inadvertent sharing of your public addresses. This setting can be configured as follows:

  1. Open the POSW app.
  2. Navigate to Settings > Public key export approval.
  3. Choose one of two options:
    • Manual approval (default): public key exports require a confirmation on the device.
    • Auto approval: public key exports are automatically approved.
POSW address formats

POSW addresses start with a D. This is the only address format. 

  Address privacy

POSW transactions are public information. Do not re-use your addresses for optimal privacy. Ledger Live automatically generates new addresses and keeps track of your previous ones. Previous addresses do remain valid, but they don't offer an optimal level of privacy.
