Types of wallet: which Bitcoin wallet suits you?

A ‘wallet’ can be an app on your phone, a program on your laptop, a small device with a display or a sheet of paper. Which type you use determines how secure your bitcoin are and how easily you can spend them. Sounds like a lot of terms? We’ll sort them out for you here, calmly and one at a time.

What a wallet actually is

A walletGlossaryWallet (Bitcoin wallet)Software or a device that manages your private keys, generates receiving addresses and signs transactions. The bitcoin itself isn’t in the wallet but on the blockchain – the wallet holds the access to it.On the learning path: Stage 5 · Step 2 – Setting up your first wallet →In the glossary →× doesn’t hold any bitcoin – they sit on the blockchain, the network’s public ledger. It holds the keys you use to sign payments.

Almost all modern wallets generate these keys from a seed phraseGlossarySeed phrase (recovery phrase)A sequence of usually 12 or 24 words from which your wallet derives all its private keys. Anyone who knows the words has full access to your bitcoin – so they belong in an offline backup and never in anyone else’s hands.On the learning path: Stage 5 · Step 3 – Backing up your seed phrase →In the glossary →×, usually 12 or 24 words following the BIP 39 standard.^[1] That’s why you can usually restore the wallet in a different app too.

The upshot: the device can be replaced, the seed phrase cannot. If your phone breaks, you restore the wallet with the words. If you lose the words and then the phone, the bitcoin are gone. How to store the words is covered in Backing up your seed phrase.

Hot or cold: the most important distinction

For your security, what matters most is whether the keys sit on a device with an internet connection.

• A hot walletGlossaryHot walletA wallet whose private keys are stored on a device connected to the internet – such as a smartphone app. Handy for payments and small amounts, but more exposed to online attacks than cold storage.On the learning path: Stage 5 · Step 1 – Understanding custody →In the glossary →× keeps them on a device that is online, usually a smartphone or computer: practical for payments and small amounts.
• With cold storageGlossaryCold storageStoring bitcoin in a way that keeps the private keys from ever touching the internet – for example on a hardware wallet or an offline device. It protects against online attacks, but requires a carefully kept backup.On the learning path: Stage 5 · Step 1 – Understanding custody →In the glossary →×, they stay offline, typically in a hardware walletTermHardware walletA small dedicated device that keeps your private keys offline and signs transactions internally.On the learning path: Stage 6 · Step 1 – Hardware wallets compared →In the glossary →AdManufacturers with a paid linkProviders from our comparisonBitBox02Hardware wallet · SwitzerlandVisit BitBox* (paid link, opens in a new window)Trezor SafeHardware wallet · Czech RepublicVisit Trezor* (paid link, opens in a new window)Blockstream JadeHardware wallet · Canada/USAVisit Blockstream Jade* (paid link, opens in a new window)All 6 compared – including non-partners →Only buy hardware wallets from the manufacturer or an authorised reseller.*Paid link: if you sign up or buy through it, we earn a commission.

You can never fully trust a computer or smartphone: malware can, for example, swap a receiving address before or after you copy it. A hardware wallet shows the address independently on its own display, and comparing the two exposes the swap.^[2] So the hot wallet is your purse, cold storage your safe.

The types of wallet in detail

Mobile wallets: the purse

For most people, an app on their smartphone is the first step into self-custody: usually no purchase price, quick to set up, always with you. But a phone can be lost, stolen or pick up malware. A mobile wallet is ideal for everyday use and practising, but not as the only place for larger savings.

Three open-source examples that we earn nothing from:

• BlueWallet keeps things simple; your private keys never leave your device.^[3]

• Phoenix is a wallet for the Lightning NetworkGlossaryLightning NetworkA second layer on top of Bitcoin for fast, low-cost payments. Amounts move off the blockchain via payment channels; only opening and closing a channel ends up in a block as a normal transaction.On the learning path: Stage 1 · Step 3 – How does Bitcoin work? →In the glossary →× with your own keys and a 12-word phrase.^[5] Lightning suits fast, low-cost small payments; how it works is explained in The Lightning Network.

Desktop wallets: the control centre

A software walletGlossarySoftware walletA wallet in the form of an app on a smartphone or computer. It stores your keys on a device with internet access – convenient and usually without a purchase price, but more vulnerable than a hardware wallet. Good for smaller amounts and for practising.On the learning path: Stage 5 · Step 2 – Setting up your first wallet →In the glossary →× on your computer offers more overview and settings than an app. A well-known example is Sparrow: open source, works with hardware wallets via USB or QR code, supports multisig and can connect to your own Bitcoin node.^[6]

Used on its own, a desktop wallet is a hot wallet too. It shows its strength as the control centre for a hardware wallet: the computer shows the balance and addresses, the device signs.

Hardware wallets: the safe

A hardware walletGlossaryHardware walletA small dedicated device that keeps your private keys offline and signs transactions internally. The key never leaves the device, so malware on your computer can’t get at it.On the learning path: Stage 6 · Step 1 – Hardware wallets compared →In the glossary →× is a small device that generates and stores the keys itself and signs payments internally. Your computer only receives the finished signature, never the key. You check addresses and amounts on the device’s display before you confirm.

Well-known manufacturers include BitBox, Trezor, Blockstream Jade and Ledger, plus, more for advanced users, COLDCARD and the DIY project SeedSigner. The hardware wallet comparison covers the differences and the security incidents at every manufacturer, including our partners.

For the safe you need a device of your own. Only buy it directly from the manufacturer or from a reseller the manufacturer names – Setting up a hardware wallet explains why.

Paper wallets: outdated

It used to be common to print out a single private key along with its address. The Bitcoin Wiki calls this method obsolete and unsafe. Many printers store the document internally, and the keys were almost always generated on a website, with all the risks of a browser wallet. A single mistyped character makes the key invalid. And anyone who spends part of it can easily overlook that the rest goes to a change address, not back to the paper.^[7]

Bitcoin-only or multi-coin?

Many wallets and devices manage other crypto assets alongside bitcoin; they hold bitcoin on the same principles. Bitcoin-only versions have a sober advantage: less code, fewer potential bugs.

If you hold only bitcoin, Bitcoin-only is the leaner choice. If you also own other crypto assets, a universal device may be more practical – both are fine.

Which wallet for which purpose?

• Practising first: a mobile wallet with a small amount you could afford to lose. Guide: Setting up your first wallet.
• Sending or paying small amounts quickly: a Lightning wallet on your phone.
• Saving for the long term: a hardware wallet with a carefully secured seed phrase, plus the manufacturer’s companion app or a desktop wallet.
• Controlling as much as possible yourself: a hardware wallet plus a desktop wallet with your own node, and possibly multisig later.

The two-wallet principle has proven itself: a purse on your phone, a safe for your savings. A lost phone then remains a small loss.
