Ledger Signers & Crypto Wallets

Thinking about buying crypto or NFTs? You’ll need a crypto wallet.

When you create a wallet, two keys are generated: a private one and a public one. The wallet stores your keys and enables you to sign transactions, generate new addresses, initiate transfers, track portfolio balances, manage your crypto, and interact with dApps.

Crypto wallets come in many forms, from hardware wallets, like Ledger's, to mobile apps that you can download on your phone or tablet.

When you buy crypto like Bitcoin and Ethereum, you’re issued two keys: one is public and the other is private.

The public key can be compared to a bank account number that you can share with third parties to receive crypto without worrying that your assets will be compromised.

The private key signs transactions and allows you to send and receive crypto. It's crucial to keep your private keys secure and secret. If anyone has access to them, they will also have access to any crypto assets associated with those keys.

A crypto wallet stores your private keys and gives you access to your assets.

There are different types of crypto wallets, each with its own benefits and drawbacks.
Hot wallets are connected to the internet and usually convenient to use, however, they are also vulnerable to online attacks. Examples include web-based, mobile, and desktop wallets. Cold wallets keep your private keys offline and out of reach of online threats. Examples include paper and hardware wallets.

Wallets can also be categorized as custodial or non-custodial, depending on who holds the private keys. Storing your crypto in a custodial wallet means that a third party controls your private keys and, therefore, your assets. In contrast, non-custodial wallets, like Ledger's, enable you to fully own and control your crypto.

Hot wallets store private keys on systems connected to the internet, which makes them susceptible to online attacks. Keeping your crypto on an exchange also means you have no true ownership or control over it. If the exchange files for bankruptcy or pauses withdrawals, you lose access to your funds.

Hardware wallets store your private keys offline, giving you full control and enhanced security. Even if you misplace or lose your hardware wallet, you can get a new one and use your Secret Recovery Phrase to access your assets.

Yes, you can manage your NFTs with Ledger hardware wallets and the Ledger Wallet app. Using your Ledger, you can safely store, send, and receive your NFTs with the peace of mind that your private keys are kept offline and secure. Ledger currently supports Ethereum and Polygon NFTs directly in the Ledger Wallet app, with more blockchains being added in the future.
