Ledger develops hardware wallet to safeguard digital assets for crypto enthusiasts. Over the last couple of years, Ledger has established itself as one of the go-to hardware wallets. The main principle behind hardware wallets is to provide full isolation between the private keys and your easy-to-hack computer or smartphone. So instead of storing your private keys on Metamask, which lives in your browser, your keys are stored on a secure element chip. Every time you initiate a transaction, you will need to unlock and approve from your hardware device since that is the only way to access your private keys required to initiate on-chain actions. Below we will go through how you can use your Ledger wallet with Zapper.

There are 2 ways to connect with your Ledger wallet on Zapper:

1. Connect directly via the native Ledger wallet integration:


2. Connect your Ledger to your Metamask wallet, and then connect with Metamask on Zapper:

What is the difference? Almost the same thing. Sometimes wallet updates tend to break connections. So if you are having issues with option 1, you could try option 2.

Once you've connected your Ledger wallet, using Zapper is just as easy as it is with Metamask - the only difference is, everytime you want to transact (e.g. add liquidity or swap assets) you will need to enter your hardware wallet password + approve the transaction from your device.

IMPORTANT: in order to interact with smart contract you will need to make sure to set your 'Contract Data' to ALLOWED. To do this, unlock your Ledger wallet, click ETHEREUM, go into settings and you should see Contract Data as the first option.

In this tutorial we will add some liquidity to the USDC/ETH pool on Uniswap V2:
