Ledger Support Coming Soon

Ledger is currently not supported and cannot be used to sign transactions on Acurast. This integration is being worked on and is expected to come soon.

Create an Acurast address with Ledger (and SubWallet)​

This guide explains how to create an address with Ledger hardware wallet. Ledger provides secure cold storage for your crypto assets by keeping your private keys offline.

info

Acurast is built on Polkadot technology, so you'll need to install the Polkadot app on your Ledger device to manage Acurast accounts.

This guide is written for Ledger hardware wallets with the SubWallet extension in a Chromium based browser. Talisman, Polkadot.js and Firefox do not fully support this setup at this point in time.

  1. A Ledger hardware wallet

  3. Your Ledger device initialized with a recovery phrase
  4. Latest firmware installed on your Ledger device
  5. A Chromium-based browser (e.g., Google Chrome, Brave, Microsoft Edge, or Chromium)
  6. SubWallet extension installed
