How to back up a crypto wallet
Learn essential techniques for securely backing up your cryptocurrency wallet to protect your assets from loss or theft.
When it comes to protecting your cryptocurrency, backups are non-negotiable. Without one, losing access to your wallet means losing your funds permanently. Here's what you need to know:
- Why Backups Matter: Devices storing your wallet can fail, get stolen, or be damaged. Without a backup, recovery is impossible.
- What a Backup Is: Typically, it's a 12–24 word seed phrase or a private key. These allow you to restore access to your wallet.
- Best Backup Methods: Write your seed phrase on paper (use acid-free paper and waterproof ink), engrave it on metal for durability, or store it securely with a hardware wallet. Never store it digitally.
- Common Mistakes: Storing your seed phrase online, sharing it, or failing to test your backup can lead to permanent loss.
Key Tip: Create multiple physical backups and store them in separate, secure locations like a fireproof safe or safety deposit box. Always prioritize offline storage for maximum security.
Seed Phrases and Private Keys Explained
Grasping the difference between seed phrases and private keys is a must for anyone safeguarding their cryptocurrency. While both are essential for accessing your funds, they serve distinct purposes and offer varying levels of security and ease of use.
What Are Seed Phrases?
A seed phrase is a set of random words that acts as a backup for your entire crypto wallet. Most wallets generate either 12 or 24 words, selected from a standardized list of 2,048 English words under the BIP-39 standard. This phrase allows you to restore your wallet if your device is lost, stolen, or damaged. Unlike resetting a password, a seed phrase can recreate all the private keys linked to your wallet, giving you access to all your accounts and addresses.
For context, a 12-word seed phrase has 2048^12 possible combinations - about 5.44×10^39. That’s a number so massive it’s practically impossible for anyone to guess.
Now, let’s break down how private keys differ.
How Private Keys Work
A private key is a unique, randomly generated number that grants access to a specific cryptocurrency address. It’s typically a 256-bit number displayed as a long alphanumeric string. The key distinction here is that while a private key provides access to a single address, a seed phrase unlocks your entire wallet, which may include multiple addresses and their associated private keys. Private keys are essentially proof of ownership, enabling you to sign transactions and send funds from a specific address.
If you lose a private key, you can no longer access the funds tied to that address. However, if you’ve securely stored your seed phrase, you can regenerate the lost private key and recover your wallet.
| Feature | Seed Phrase | Private Key |
|---|---|---|
| Format | 12–24 simple words | Long alphanumeric string |
| Function | Master backup for the wallet | Unlocks one wallet address |
| Use Case | Restores the entire wallet | Authorizes transactions for one address |
| Risk | Exposure compromises all funds | Exposure affects one address |
Knowing these differences is essential when deciding how to store them securely.
Mistakes to Avoid
Mismanaging seed phrases or private keys can result in permanent loss of funds. In one notable case from 2022, a MetaMask user lost $655,388 after hackers accessed the wallet’s seed phrase stored in an iCloud backup. The attackers, posing as Apple support, tricked the victim into sharing a verification code, which let them reset the Apple account password and retrieve the seed phrase.
To avoid such disasters, never store your seed phrase digitally - this includes screenshots, notes apps, cloud storage, or email drafts. Human error is a weak link, and cloud breaches frequently expose sensitive data.
"Anyone with these words can move your coins, so treat them like physical cash: keep them private, offline, and secure." – Blockstream
Other critical errors include sharing your seed phrase with others, failing to test your backup, and relying solely on memory instead of creating physical copies. Always record your seed phrase in the exact order it’s provided, and consider numbering the words to avoid confusion. Similarly, never share your private key with anyone.
If you lose both your private key and seed phrase, your wallet becomes permanently inaccessible. This is why proper backup and secure storage are non-negotiable when protecting your cryptocurrency.
Safe Backup Methods
The way you back up your crypto wallet can mean the difference between recovering your funds or losing them forever. Each method offers varying levels of safety, durability, and ease of use. Here are three reliable ways to back up your wallet.
Paper Backups
Writing your seed phrase on paper is one of the simplest and most affordable backup options. All you need is a pen and a sheet of paper, making it easy for anyone to implement. However, for better durability, use acid-free paper and waterproof ink. Regular paper can deteriorate over time, especially when exposed to humidity or light, whereas acid-free paper resists yellowing and breakdown.
Storing your paper backup securely is just as important. Place it in a waterproof and fireproof safe, or even consider a safety deposit box at a bank. Some users go a step further by creating multiple copies and storing them in different locations to guard against theft or natural disasters.
Avoid laminating the paper, as it can trap moisture. Instead, use tamper-evident bags to protect it from water and damage. For extra precaution, you might write the seed phrase with both pen and pencil to prevent issues like ink smudging or pencil fading over time.
Metal Backups
Metal backups are a step up in durability, offering robust protection against fire, water, and physical damage. This method involves engraving or stamping your seed phrase onto a metal plate, such as stainless steel or titanium. These materials are highly resistant to corrosion and can endure extreme conditions that would destroy paper backups.
"Cryptosteel is THE most secure way to back up a cryptographic private key or seed. Cryptosteels give you CCSS Level 3 compliance right out of the box, being impervious to fire, flood, static electricity and even EMPs. I truly believe there is no better alternative."
– Michael Perklin, Cryptocurrency Security Expert and CISO at ShapeShift.io
Metal backups are ideal for those seeking a long-lasting and nearly indestructible solution.
Hardware Wallets and Cold Storage
Hardware wallets provide offline storage for your private keys, keeping them safe from online threats. However, it’s important to note that the device itself is not a backup. The seed phrase generated during setup is what you’ll need to secure separately.
The seed phrase is critical because it allows you to restore your wallet if the device is lost, stolen, or damaged. Hardware wallets are highly effective at isolating your private keys from internet-connected devices, significantly reducing the risk of hacking.
While hardware wallets excel in security, always ensure your seed phrase is backed up using one of the other methods, such as paper or metal, for added peace of mind.
Backup Methods Comparison
Here’s a quick overview of the different backup methods:
| Backup Method | Description | Security Level | Key Considerations |
|---|---|---|---|
| Paper Backups | Handwritten seed phrases on paper | Basic | Prone to fire, water, and physical degradation |
| Metal Backups | Engraved or stamped seed phrases on metal | High | Resistant to fire, water, and physical damage |
| Hardware Wallets & Cold Storage | Offline storage of private keys via dedicated devices | High | Requires separate seed phrase backup; potential for hardware failure |
Each method has its strengths and weaknesses, so choosing the right one - or even combining methods - can help ensure your crypto assets remain secure.
How to Create a Backup Step by Step
Creating a secure backup for your crypto wallet is a must. Here’s a step-by-step guide to help you do it right.
Setting Up Your Wallet
When you first set up your crypto wallet, it generates a 12- to 24-word seed phrase. This phrase is the master key to your wallet, and getting it right is critical. Write it down immediately - by hand, not digitally. Avoid taking pictures or saving it on your phone or computer, as these can be compromised. Use a piece of paper and carefully record each word in the correct order, double-checking for accuracy.
For instance, if you’re using Blockchain.com, you can access your recovery phrase by navigating to Profile > Security. Once displayed, manually write down the 12-word phrase exactly as shown.
After recording your seed phrase, you’re ready to decide on a backup method.
Choosing a Backup Method
Pick a backup method that aligns with your security needs and budget. Here are some common options:
- Paper backups: Use acid-free paper and waterproof ink for durability.
- Metal backups: Advanced users may prefer metal plates, which are resistant to fire and water.
- Hardware wallets: While these are great for storing your crypto, remember that the device itself isn’t the backup - the seed phrase is.
Whichever method you choose, prioritize its long-term security and accessibility.
Storing and Checking Your Backup
Keep your backup offline in a secure location, such as a fireproof and waterproof safe or a bank deposit box. To add an extra layer of security, create multiple copies and store them in different locations. This protects against localized disasters like fires or floods.
Regularly check your backup to ensure it’s still legible and functional. If you notice any damage or issues during verification, transfer your funds to a new wallet immediately.

| Metal Backup | High | Medium | Medium | $59 – $79 | Long-term storage, disaster prep |
| Hardware Wallet | Medium | High | Medium | $129 – $169 | Active traders, frequent access |
| Multi-Share Backup | Medium | High | Medium | Varies | Advanced users, top-tier security |
Paper backups are simple and inexpensive, making them a go-to for beginners. However, they’re highly susceptible to damage from water, fire, or general wear and tear, which makes them better suited for short-term use.
Metal backups provide a much sturdier solution. Options like Material Bitcoin ($59–$79) allow you to engrave your seed phrase onto metal plates that can withstand fire, water, and corrosion. These are ideal for long-term storage when you don’t need regular access to your funds.
Hardware wallets strike a balance between security and usability. Devices like the Ledger Nano X ($149) and Trezor Safe 5 ($169) come with features such as PIN protection, tamper-proof designs, and user-friendly interfaces. They’re perfect for traders or DeFi users who need frequent access while maintaining strong security.
Multi-share backups are for those seeking maximum security. Tools like the Cypherock X1 utilize Shamir's Secret Sharing to split your private key into multiple parts, requiring at least two parts to restore access. This method reduces the risk of a single point of failure but does require a higher level of technical know-how.
Ultimately, the best backup method depends on your specific needs. Think about how often you’ll access your funds, how much you’re willing to spend, and your level of technical comfort when making your choice. Use this comparison to safeguard your crypto assets effectively.
Summary and Best Practices
Key Points
Backing up your crypto wallet is a must if you want to safeguard your digital assets. As Vault12 explains:
"Proper crypto wallet backups protect you from threats ranging from criminal actors and accidents to natural disasters and damage. Once securely backed up, you can recover your assets in times of need".
The foundation of your wallet's security lies in your 12–24 word seed phrase - this is your wallet's master key. Keeping it safe requires offline storage in a secure location to prevent unauthorized access.
When deciding on a backup method, think about your specific needs. Paper backups are simple and can work for beginners or short-term use but are vulnerable to physical damage. For more durability, consider metal backups, where your seed phrase is engraved on materials that resist fire, water, and corrosion, making them ideal for long-term storage. Hardware wallets strike a good balance between security and usability, making them a solid choice for active users.
Physical security is key. Create multiple copies of your seed phrase and store them in separate, secure spots, like a fireproof safe or a bank's safe deposit box. Avoid digital storage altogether - don’t take screenshots, save files on your computer, or use cloud services for your seed phrase. For added protection, you might split your seed phrase using Shamir Secret Sharing, which divides it into parts that can be reassembled only with a specific number of pieces.
Next Steps
To secure your wallet effectively, start by choosing a backup method that works for you. Write your seed phrase on paper or engrave it on metal plates, then store copies in at least two secure locations. Test your backup on a separate device to ensure it works as expected.
Make it a habit to review your backup every six months to confirm it remains legible and secure. Storing copies in geographically distant locations can provide extra protection against events like natural disasters.
Lastly, think about setting up an inheritance plan so trusted individuals can access your seed phrase if needed. Strengthen your security further by using strong, unique PINs for your hardware wallet and adding a passphrase for an extra layer of protection.
FAQs
What can I do if I lose both my seed phrase and private key?
Losing your seed phrase and private key can be a devastating situation since they are the ONLY tools that grant access to your crypto wallet. If you still have wallet access, act quickly - transfer your funds to a new wallet with a freshly generated seed phrase and private key. This step is crucial to keeping your assets safe.
However, if you've already lost access and don’t have a backup of your seed phrase or private key, the reality is harsh: recovery is usually not possible, and your assets could be gone for good.
