3.3 Setting Up Your Crypto Wallet Safely

Setting Up Your Crypto Wallet Safely

What you will understand after this chapter

What crypto wallets are and how they relate to control of your private keys on a blockchain.

The differences between “hot” (online) and “cold” (offline) wallets and typical trade‑offs between convenience and security.

Key practical steps and habits that can reduce (but not remove) the risk of losing access to funds held in a wallet.

This chapter is for general information only and is not a recommendation to buy, sell or hold any cryptoasset.

What is a crypto wallet?

A crypto wallet is a tool (software or hardware) that helps you manage the private keys that control cryptoassets recorded on a blockchain.

Unlike a bank account, where a financial institution manages your balance, a non custodial wallet means you (or your device) hold the keys yourself. If those keys – or the backup phrase associated with them – are lost or compromised, you may not be able to recover your assets.

Wallets can be thought of as interfaces to the blockchain, rather than places where coins are physically stored.

Types of crypto wallets

Broadly, wallets are often grouped into:

Hot wallets

Hot wallets are connected to the internet (for example mobile apps, desktop software or browser extensions). They are convenient for sending and receiving crypto and for frequent interaction with applications.

However, being online means they can be more exposed to risks such as malware, phishing and compromised devices.

Cold wallets

Cold wallets keep private keys offline (for example hardware devices or other offline storage methods). They can reduce some types of online attack risk, which is why people sometimes use them for larger or longer‑term holdings once they understand how they work.

Cold storage still has risks, including loss, damage or theft of the device or backups, and user mistakes during setup or recovery.

No wallet type is completely safe or suitable for everyone; each involves trade offs.

Choosing a wallet type

When thinking about which wallet type to learn about or use, people often consider:

The size and purpose of any holdings (small test amounts vs larger sums).

How frequently they expect to transact.

Their own comfort with managing backups and security.

Some beginners start by learning with small amounts in a hot wallet and only consider more complex setups (such as hardware devices) once they are confident about the basics. This is a description of what some people do, not a recommendation.

Setting up a wallet: key steps and safeguards

If you decide to set up a wallet, typical steps include:

1. Obtain the wallet software or device

Only download software wallets from official websites or trusted app stores.

For hardware wallets, purchase directly from the manufacturer or authorised resellers where possible and check for tampering.

2. Create the wallet and record the recovery phrase

Most non custodial wallets generate a recovery or “seed” phrase (often 12–24 words) that can recreate your keys on another device.

Good practice usually includes:

Writing the phrase down clearly and keeping it offline.

Storing it in one or more secure locations.

Never typing it into websites, sending it by email, or sharing it with anyone.

Anyone with your seed phrase can usually access the assets associated with that wallet.

3. Add local security

Where supported:

Use strong, unique passwords or passphrases.

Enable additional security features such as app level PINs or biometric locks.

These measures help protect against someone using your device, but they do not replace the need to keep seed phrases private.

4. Test with small amounts

If you move assets into a new wallet, it can be sensible to:

Start with a small test transaction.

Confirm that you can see the funds and send a small amount back out.

This can help you understand how addresses and networks work before moving larger sums.

Wallet security habits

To reduce (but not eliminate) risk:

Keep seed phrases and private keys offline and never share them, even with someone claiming to be “support”.

Keep software up to date from official sources.

Be cautious when connecting wallets to websites or apps; only use services you understand and trust.

Double check addresses and networks before sending funds; mistakes can be irreversible.

If you lose a device or seed phrase

If you lose a device but still have the correct seed phrase, many wallets allow you to restore access on another compatible device.

If you lose both the device and the seed phrase for a non custodial wallet, access to the associated assets is likely to be permanently lost. There is usually no central party who can restore this for you.

Wallets and exchanges

Some people keep assets on exchanges (custodial wallets), where the platform controls the keys. Others prefer to move some or all holdings into their own wallets. Each approach has different risks:

Custodial: platform failure, hacking, or withdrawal restrictions.

Non custodial: user error, loss or compromise of keys/seed phrase.

Understanding these differences can help you see that neither route is risk free.

Your choice of wallet and how you set it up can significantly affect the types of risk you face when interacting with cryptoassets.

This chapter is about helping you understand those tools and trade offs.

It does not mean you should hold crypto or move it off an exchange, and if you are unsure whether crypto is appropriate for you at all, consider seeking independent financial advice.
