NFTs, or non-fungible tokens, are a type of cryptocurrency that possess unique attributes, making each token distinct from others. Unlike fungible tokens that are interchangeable, NFTs are unique and distinct, which means they cannot be replaced or exchanged for another token on a one-to-one basis. This makes NFTs ideal for representing unique digital assets like collectible items, artwork, and other assets that have intrinsic value.
As the popularity of NFTs grows, robust security becomes more important. Trezor hardware wallets are designed to store cryptocurrency of various types, and your Trezor can be used to store and secure NFTs, as long as they exist on a network which is already supported in device firmware, such as Ethereum.
While Trezor hardware wallets are capable of storing NFTs, currently they cannot be managed directly through Trezor Suite. To manage NFTs safely, a third-party interface like MetaMask
should be utilized. By connecting MetaMask
directly with your Trezor device, you can ensure that your seed remains offline, providing additional security for your NFT holdings.
Trezor Hardware Wallets and Ethereum Improvement Proposals
Trezor hardware wallets support two Ethereum Improvement Proposals (EIPs), EIP-1559 and EIP-712.
EIP-1559: This proposal makes gas prices more predictable, making it a suitable choice when buying NFTs. Trezor models both support EIP-1559, reducing the risk of failed transactions and potentially reducing transaction costs in the long run.
EIP-721: This NFT standard provides rules for handling NFT metadata and is different from the ERC-20 standard as it is tailored to each unique token rather than multiple identical fungible tokens.
EIP-712: This proposal improves the presentation of data during signing and is frequently encountered when listing NFTs for sale on certain marketplaces.
This standard is now fully supported by MetaMask as well as both Trezor models.
How to manage your NFTs with Trezor
To store NFTs with a Trezor hardware wallet, you will need to have a third-party app installed that is capable of managing NFTs. One popular app is MetaMask, a browser wallet extension that supports Ethereum NFTs.
Follow this step-by-step guide and Trezor your NFTs safely and securely.
To store NFTs, all you need is an Ethereum address to send them to. Set up an Ethereum account in Trezor Suite
- In Trezor Suite, visit the Accounts page and click the green plus (+) sign next to My Accounts.
- This will open a menu for adding new coins. Click on Activate more coins, choose Ethereum from the list, and click Find my Ethereum accounts.
- Now you have a new empty Ethereum Account. To get your receiving address, stay on the Ethereum account main page and click Receive, and then Show full address.
Double-check every character of that address against the one shown on your Trezor screen. If they match, you’re good to go and can copy the address. If not, there may be malware on your host computer and the address must not be used.
Connect your Trezor to MetaMask or another interface
Now that you have an address to send your NFTs to, you can set up MetaMask which will communicate with the NFT marketplace you plan to use.
- To connect to MetaMask, first install the extension and create a new account with a password, and write down a backup of the recovery seed it generates. This account will not be used but it needs to be set up before you can add a hardware wallet to the extension.
- Next, click on the circle in the top-right of MetaMask interface. A dropdown will appear showing all connected accounts. Click Connect Hardware Wallet and a new page will open.
- Choose Trezor from the options shown and you will be redirected to Trezor Connect. This is Trezor software that allows third-party apps to communicate securely with your device.
- Select which Trezor you wish to use and allow the MetaMask extension to read public keys from it.
- Check the account you are exporting is correct and click Export. Your Trezor must be connected and unlocked. Then, enter any passphrase associated with the account.
- Now, MetaMask can read your public keys, and see which Ethereum accounts are associated with your Trezor seed.
- Select an account to use, making sure you choose the one you set up earlier, usually the first option on the list, and click Unlock.
Your NFT will not be lost if you accidentally choose the wrong account to use with MetaMask at this step, but for security reasons you should make sure it perfectly matches the address shown on your Trezor in the previous step. Ethereum accounts only have one address associated with them, so the other accounts shown at this step can be found by adding more Ethereum accounts in Trezor suite, as shown in step 1.
Your wallet address will now be ‘watched’ by MetaMask and any transactions initiated through this MetaMask account will need to be signed by your Trezor.
Now you can use MetaMask to manage NFTs on any supported platform and, as long as you ensure you always use the account connected to your hardware wallet, all your Ethereum and related assets will be secured offline by your Trezor.
Once you have confimred the address using your Trezor and have double-checked the address matches the one you imported into MetaMask, you can start using it for receiving NFTs, ERC-20 tokens and other Ethereum transactions.
