TL;DRThis guide shows you how to set up and use a crypto hardware wallet, using the Trezor Safe 3 as an example. You’ll learn to safely store Bitcoin, Ethereum and other assets offline, with clear steps for wallet setup, seed phrase backup, PIN protection and secure transaction signing. The article also explains how to connect your hardware wallet to MetaMask for use with DeFi platforms and NFTs – all while keeping your private keys offline. Whether you’re comparing the best hardware wallets in 2025 or need a crypto wallet tutorial for receiving and sending funds, this guide has you covered with actionable tips and best practices for long-term cold storage security.If you’re ready to take crypto wallet security seriously, using a hardware wallet is one of the best steps you can take. You may already be aware of its advantages over a software wallet: keeping your private keys offline, minimizing exposure to malware and giving you full ownership of your crypto assets. Maybe you’ve even picked out your device.The good news? While there are several options out there, from Ledger to Trezor to newer multichain hardware wallets, the basic experience is similar. This hardware wallet setup guide will walk you through unboxing, verifying the device, securing your PIN and backing up your seed phrase.For illustration purposes, this article uses the Trezor Safe 3, an ideal device for beginners but powerful enough for advanced users. It’s also a great choice if you want to use a hardware wallet for DeFi or connect your hardware wallet to MetaMask.Let’s get into it.Unboxing your crypto cold walletBefore you begin setup, here’s what comes with a typical hardware wallet, in this case, the Trezor Safe 3. This applies to most of the best hardware wallets in 2025.What’s in the box:Trezor Safe 3 device with tamper-evident seal.USB-C cable.Two recovery seed cards (for your wallet backup).Quick start guide.Trezor stickers.First steps: Inspect and verifyBefore plugging anything in, check for:Sealed, undamaged packaging.Intact holographic sticker over the USB port.This ensures your device hasn’t been tampered with, a crucial crypto wallet security tip. Newer devices (post-April 2024) have upgraded seals for added air-gapped security.If anything looks suspicious, contact Trezor support.Power it upPeel the sticker and connect via USB — the Safe 3 powers on automatically, and no battery or power button is needed.You’ll notice a small screen and two physical buttons. These are how you’ll confirm actions, approve transactions and manage your crypto.Let’s begin the setup.Hardware wallet setup: Trezor Safe 3Getting started takes about 10–15 minutes. For this crypto hardware wallet tutorial, just have your computer ready and a pen handy. You’ll soon need to write down something very important.Step 1: Download Trezor SuiteGo to the official Trezor site and download the Trezor Suite app. It’s available on Windows, macOS, Linux and via web browser.Open it, plug in your device and follow the prompts. Click “Set up my Trezor.”Step 2: Install firmwareYour device may not come with firmware pre-installed. Click “Install Firmware.” This is part of the crypto wallet recovery process and ensures a secure, clean slate.Step 3: Verify device authenticityClick “Let’s check your device” in Trezor Suite. Press the right button on your Safe 3 to authenticate. You’ll see a message confirming the device is verified.Step 4: Quick tutorialThe device might walk you through button usage. Just follow along, it’s a one-time setup.Step 5: Create a new walletYou’ll see two options:Create new wallet (choose this if it’s your first time).Recover wallet (for restoring, using your seed phrase).Step 6: Backup methodYou’ll choose between:Standard seed backup (easiest and most common).Shamir backup (advanced; splits the seed into parts).Stick with standard, unless you’re sure you know what you’re doing.Step 7: Confirm on deviceUse the buttons to confirm your backup method and agree to terms. Press “Create wallet” to proceed.Step 8: Write down your recovery seedThis is the heart of your cold storage for crypto. The device will generate a random list of 12, 20 or 24 words, your recovery seed.Trezor will remind you not to take photos or digital notes of the seed. Write it down on the provided card and store your crypto seed phrase safely. This is critical for future recovery.Step 9: Confirm the seedYou’ll be tested on a few of the words (e.g., “What’s word #5?”). Select the correct ones using the buttons. Once confirmed, your backup is complete.Pro tip: Make a second copy of your seed and store it in a different secure location. This adds an extra layer of protection.Step 10: Set up a PINNow, create your hardware wallet PIN. In Trezor Suite, click “Set PIN.” The device will prompt you with a randomized layout. Use the buttons to choose your digits.PINs can be up to 50 digits long. Choose something memorable, but not obvious. If forgotten, you’ll need to wipe the wallet and recover with the seed phrase.Step 11: Enable coins and final setupYou’ll now choose which coins to enable, Bitcoin (BTC), Ether (ETH) and more. This step also prepares your wallet for use with DApps or storing Bitcoin in a hardware wallet.After clicking “Complete Setup,” you can name your device or customize the home screen. Then hit “Access Suite” to open your dashboard.If you’ve been following along on your own device, you’ve just completed your first hardware wallet setup and taken a major step toward storing crypto safely!Receiving crypto with a hardware walletOnce your device is set up, you’re ready to store crypto safely by receiving funds into your wallet. Here’s how to accept crypto securely with your Trezor hardware wallet.1. Open the correct accountIn Trezor Suite, choose the account for the crypto you want to receive (e.g., Bitcoin #1 or Ether #1). Click the “Receive” tab to generate a crypto cold wallet address.2. Show and confirm the addressClick “Show full address” in the app. Your Trezor will display the full address on its screen. Always confirm the address on the hardware wallet itself, not just in your browser. This ensures it hasn’t been altered by malware on your computer (a standard crypto wallet security tip).3. Use the addressCopy the address or scan the QR code to send crypto. Your Trezor doesn’t need to stay connected; the blockchain will receive the funds and update your balance next time you plug the wallet in.Pro tips for safe receiving:Confirm addresses on your device, not just your screen.Use a fresh address each time for added privacy (Trezor Suite supports this).If the address doesn’t match between your wallet and app, stop immediately.Sending crypto from a hardware walletSending crypto with a hardware wallet means your private key stays offline, even while broadcasting a transaction. Here’s how to do it securely:1. Select the correct accountIn the Trezor Suite, go to the account holding the asset you want to send. Click “Send.”2. Fill in transaction detailsEnter the recipient’s wallet address and the amount to send. You can also toggle to fiat view if needed. Double-check the recipient address to avoid mistakes.3. Choose a FeeFor Bitcoin, you can select from fee levels: Low, Standard or High.For Ether or ERC-20 tokens, Trezor Suite estimates gas fees automatically.4. Confirm on the deviceClick “Review & Send.” Your Trezor will display the transaction details:Destination address.Amount.Network fee.Only approve the transaction if everything checks out. This is how you protect yourself from clipboard malware.5. Done, signed transaction is now sent!Your signed transaction has now been sent, with zero exposure of your private key. You’ll see the confirmation in your history.More pro tips:If your Trezor asks to sign a transaction you didn’t initiate, cancel immediately.Make sure your ETH balance is sufficient to cover gas for token transfers.For advanced users: Trezor also supports air-gapped security setups using microSD backups.Using a hardware wallet with MetaMask and DAppsWant to use your hardware wallet for DeFi or NFTs while keeping your keys secure? Trezor Safe 3 integrates seamlessly with MetaMask, making it easy to use DApps and sign transactions safely.1. Connect Trezor to MetaMaskOpen MetaMask in your browser. Click your account icon and choose “Connect Hardware Wallet.” Select Trezor when prompted.2. Plug in your TrezorIf not already connected, plug in the device. MetaMask may prompt you to install Trezor Bridge, a utility that enables communication with the wallet.You’ll be asked to approve the reading of your public key from the hardware wallet. This is safe and doesn’t reveal private keys.3. Select a wallet addressMetaMask will list your Trezor-linked Ethereum addresses. Choose one (e.g., Ethereum #1) and click “Unlock.” The wallet will now appear in MetaMask, marked as a hardware wallet.How it worksFrom now on, every time you make a transaction, whether it’s swapping tokens on Uniswap or minting an NFT, you will:Initiate the transaction in MetaMask.See the details appear on your Trezor screen.Physically confirm the transaction using your device buttons.This flow ensures that even if your browser is compromised, the final transaction approval happens on your trusted hardware wallet.Final safety tip: Your hardware wallet screen is the most trustworthy place to verify transaction details.
