Welcome to NuFi wallet's knowledge base. Learn more about NuFi (and access the wallet) on our homepage here or ask a question in our Discord server here.

This article explains how to pair a GridPlus Lattice1 hardware wallet with NuFi wallet so that you can manage your GridPlus Solana, Ethereum and EVM accounts inside NuFi's interface.



Doing this gives you access to functionality such as cross-chain swaps for thousands of tokens, in-app DEXes, DeFi and other Decentralized Apps (Dapps), Solana staking, and more.


It takes about a minute to set up a NuFi wallet profile and pair your device's account(s) into NuFi's interface.



TABLE OF CONTENTS

  • Connect your GridPlus accounts to DeFi and other Decentralized Apps (Dapps)
  • Stake SOL direct to the blockchain

  • Solana DEX inside your wallet  
  • Buy and sell crypto with card, Apple/Google pay, PayPal and others
  • View and export your wallet's transaction and staking history

Important

  • When you pair a GridPlus device with NuFi wallet, your crypto remains in your GridPlus wallet.
  • By pairing, you simply share your wallet's public address(es) so that NuFi can query the blockchain and show you the contents of your wallet, plus its staking setup, history, and so on.
  • Your wallet's private keys are never shared with NuFi - these always remain inside the GridPlus device itself.
  • You must always pair a GridPlus device using the wireless or cable method, and never by entering the device's seed/recovery phrase online.
  • NuFi is a non-custodial wallet and cannot access or control any of the funds you manage via NuFi's interface.


Setup


Before you continue, please ensure that your GridPlus device's firmware is up to date.


1. Create a NuFi wallet profile

Before you can manage your GridPlus accounts in NuFi's interface, you must create a NuFi wallet profile and pair your device's accounts into it.


There are two versions of NuFi wallet:

  1. a browser extension that you install from Chrome web store; and
  2. a web-based wallet accessed via a URL (with nothing to install).


Both versions of NuFi support GridPlus Lattice1, but they differ in terms of Dapp connectivity; the browser extension connects to all Dapps, while the web wallet connects to any Dapp that supports WalletConnect.

2. Pair your GridPlus accounts with NuFi wallet


  1. Open NuFi wallet's browser extension or visit wallet.nu.fi; click 'Pair hardware wallet' on the first screen
  2. Follow the on-screen instructions to create a NuFi wallet profile:

    - This allows you to log in quickly on your next visit without needing to connect your GridPlus device (but you will always need to connect your device in order to sign transactions).

    - Write down your NuFi wallet's recovery phrase or skip this step if you don't plan to create any non-hardware wallet accounts.
     
  3. Follow the on-screen instructions to export your GridPlus wallet's public keys:

    - Select the desired blockchain and select GridPlus. Enter your device ID and password.     When NuFi receives your device's public keys, you'll see your accounts and balances listed for that particular blockchain.

  4. Choose which account(s) you would like to pair with NuFi and click Continue.

    - Choose a custom name for each account if you wish.

    Important: For some blockchains, different accounts can be derived from the same public key. NuFi shows you, in separate tabs at the top, each derivation path and the resulting accounts (with balances).


3. Your GridPlus accounts and assets will be visible inside NuFi's interface


Repeat the process for each blockchain/account you want to manage via NuFi's interface. You can pair your device's existing accounts or create new ones at any time from Portfolio > Accounts tab > Add account, as shown here:
