How to Self-Custody, Back Up, and Inherit NFTs with Vault12

NFTs enable creators to revolutionize art, but they also support additional use cases, including digitization of many types of unique physical and digital goods (such as concert tickets and identity documents). Learn how you can protect these valuable assets with Vault12.


An NFT ("Niftie") is a blockchain token that is associated with a specific physical or digital asset that has a unique form and value. In contrast, cryptocurrencies such as BTC, ETH, or other altcoins are interchangeable with others of the same type (for example, 1 bitcoin (BTC) = any other BTC).

NFTs can be linked to unique physical assets, e.g., a diamond, a piece of physical art, a digital asset like an online concert ticket, or digital art.

NFTs can be tracked on a blockchain as they are transferred or sold to other people. As an added twist, NFTs can even be programmed so that when they are sold on the secondary market, a portion of the proceeds are automatically sent to the creator, thus creating a whole new motivational value chain for the creator economy.

NFT functionality is still in its infancy, but has the potential to fundamentally change how all types of assets are traded.

You should protect the NFTs you own by using Vault12 to securely back up the wallet that holds the keys to your NFTs. It is especially important for creators, who may have authored a myriad of NFTs, to protect the keys to their NFT wallets, since all proof of ownership revolves around protecting those keys.

What is an NFT?

NFTs, or Non-Fungible Tokens (also known as "Nifties"), are digital assets tracked on a blockchain like any other digital token. The term "non-fungible" means that each token is unique. An NFT and its trading history can be tracked on the blockchain. Unlike Bitcoin, where each BTC is valued the same as any other BTC, NFTs can have different values depending on their attributes, and depending on their unique market demand.

NFTs come in all shapes and sizes, but all of them have two key properties:

  1. They are linked to actual assets - either physical or digital. Effectively, NFTs express the immutable right of possession. This right is cryptographically fixed in a blockchain as an advanced digital version of a "certificate of ownership."
  2. They are tracked on the blockchain so that their ownership history can always be verified. This means that not only digital items can be tracked, but physical items that have been tokenized and represented as an NFT can be tracked as well.
This opens a wide range of use cases for NFTs:

Art: Both digital and physical art can be tokenized, traded, and tracked via a blockchain. In a famous example from March 2021, a JPG image produced by digital artist "Beeple" fetched $69 million (lol) in an auction run by famous auction house Christie's. Other high-profile artists, musicians, and creators are creating new art, as well as tokenizing their historical catalogs.

Plane Tickets: Yes, plane tickets (in fact, tickets of all kinds) can be issued, tracked, transferred, and even bought and sold, optionally with a percentage of the ticket price going back to the original issuers.

Baseball Cards: Cards and other collectibles, including limited edition items, can be registered, traded and collected.

Real-world physical assets: Real-world valuable assets like diamonds or real estate can also be tokenized, and then traded! As long as there is clear provenance (a known source, or history of ownership) for the physical items, they can easily be traded on a global market, once they are registered as NFTs.

As for the future of NFTs, there are some incredible possibilities for how Smart Contracts will increase the utility of NFTs even more by supplementing them with real-world, dynamic data. Just consider the possibilities for NFTs beyond their usual function (serving as a record of the chain of custody and ownership): GPS location data can show the physical location of an NFT-tokenized object; real or virtual sports outcomes can offer additional token "rewards" to NFT owners; economic data can be used to automatically modify interest rates used for NFT-tokenized mortgage agreements. A dynamic NFT becomes a trackable asset that can be used for various contractual relationships besides just collectible trading.


How are NFTs different from Cryptocurrency?

Most NFTs live on the Ethereum blockchain, although some other blockchains also offer NFT support. Unlike cryptocurrency coins like Ether, which are interchangeable with other coins of the same type (fungible), NFTs are unique (just like snowflakes)! So what gets tracked on the blockchain for any given NFT captures its unique properties, as well as its trading history.

How do I create an NFT?

To create an NFT, first choose a blockchain network. Ethereum has the widest range of NFTs today, but some other blockchains that support NFTs include Binance Smart Chain, Flow by Dapper Labs, Tron, Polkadot, Tezos, Cosmos, and WAX, to name a few. Your choice of NFT blockchain network will determine which exchanges and crypto wallets will interoperate with your NFT.

If you choose to use Ethereum for your NFT, you will need a crypto wallet that supports the associated ERC-721 standard. Examples of these wallets are MetaMask, Trust Wallet, Coinbase Wallet, or Rainbow. In addition, you will need some funds in Ether (ETH). All Ethereum transactions will cost a transaction processing fee (also called a "gas" fee).

The NFT trading platforms that enable you to create NFTs include OpenSea, Rarible, and Mintable. To use these NFT platforms, connect your crypto wallet to the platform, click the "Create" button, upload your digital art or other NFT format, and accept the contract terms and details. Once your NFT is signed with your wallet, your NFT is ready to go and can be listed on the blockchain.

How do I buy an NFT?

There are lots of sources to buy NFTs, and there are more coming online every day. The most popular platforms include:

How do I secure, protect, and back up my NFTs?

NFTs are registered on the blockchain and linked to your wallet address, so backing up your NFTs follows the same process as backing up a wallet's seed phrase.

If you own the digital art source file itself (regardless of its format), you can also back this up in a Digital Vault. This ensures that your copy of the art is also protected from being accidentally deleted or lost. This is especially important for NFT art that may happen to pass through many hands (e.g., auction houses), and is also important for insurance purposes.

Read on for step-by-step instructions for how to protect your NFTs and original artwork using Vault12.

How to back up from an NFT Platform

Once a creator or developer has created an asset, it needs to be "minted" on an NFT platform. Minting is the process of registering the asset on the blockchain and activating the smart contract that governs the NFT (e.g., these terms can include what percentage of future sales are credited back to the creator). Once minted, the NFT can be made available for purchase. Buyers will purchase from the NFT platform directly, using their crypto wallet.

NFT Platforms support wallets in different ways. Some wallets can display NFT records, others cannot (we're still in early days of this technology).

In the following example, we will use (a leading NFT platform), and the Metamask mobile wallet:

With NFTs (as with standard cryptocurrency), the wallet seed phrase becomes the most important piece of information to back up and secure.

Here's how to reveal the seed phrase in our Metamask Wallet so that it can be backed up:

Backing up your Crypto Wallet

Once you have access to your seed phrase, you can back it up with a Digital Vault from Vault12.

In the following sections, we will demonstrate how owners of NFTs, as well as creators, can utilize a Digital Vault as the mechanism to store seed phrases, as well as secure the original asset.

How can NFT Owners Use a Digital Vault to back up NFTs?

A Digital Vault has the advantage of being focused on a singular purpose: securely storing digital assets for long term use. While there are many types of "digital vaults" available for cryptocurrency storage, for NFTs it is better to use something that is independent of any one blockchain and can store any type of digital asset.

Here we will use Vault12 to demonstrate how an NFT can be backed up, and how digital assets can also be stored in a Vault:

Step 1: Create and configure a Digital Vault


Step 2: Add a new asset to your Vault: in this case an NFT. First, switch to the Vault screen by tapping on the vault icon on the bottom navigation pane. Tap Add an Asset, and choose NFTs.

How can you back up your NFT seed phrase in Vault12?

Start by choosing "Add a Seed Phrase" to add your NFT wallet's seed phrase. For convenience, the name of the software wallet type that you use to control the NFT will be suggested, but you can use any name.

Entering the seed phrase could be done by choosing either "Enter each word," or "Free format text." If you want to refresh your memory about the details of seed phrases, you can do that here.

As soon as you finish entering the seed phrase words, choose the name for the asset (or use the one proposed by the application), and choose between storing whether you want to hold the local copy, or only store a backup with your Vault Guardians.

Finally, you will be returned to the Digital Vault screen that will display your added asset and indicate the status of its distribution to your Guardians.

Creators: Use a Digital Vault to back up NFTs and original artwork

For creators, in addition to backing up wallets that contain NFT collections, there's also the option to back up the original artwork itself - this could be the form of an image, video or some other file format.

To add the artwork to your Vault, simply tap the "Add an Asset" option on your Vault screen, then choose "Add Media."

In this simple way, you can add files, images, or other media from files on your device or from your Photo Library to back up the source files of your highly valuable media.

The final step is to give a name to your selected asset (you can associate it with the seed phrase name, to ease tracking of inventory), and choose whether you want to keep a local copy.

How to unlock and access assets in the Vault?

To gain access to your asset or artwork, select the asset in your Vault, and tap the "Unlock Asset" option.

To learn more about accessing the assets that are locked in your Vault, please read How to access your Seed Phrase or asset stored in Vault12.

The NFT market is new and constantly evolving, and there have already been hacking attempts on several platforms where owners and creators ended up having their accounts drained. Please make sure that you are using well-known and highly trusted wallets to associate with your collection of NFTs. Follow the guidelines laid out in this article to make sure you are able to robustly secure and back up your NFTs - whether you bought them or created them yourself.
