Digital Wallets

Fortress's digital wallets will enable you to bring crypto and NFTs to the 99% who aren't technical enough to use existing wallets like MetaMask and Phantom. Using our API's, you'll be able to:

  • Create new digital wallets
  • Deposit multiple assets across multiple blockchains in the same place
  • Store crypto, NFTs, stablecoins, utility tokens, and more
  • Send and receive crypto and NFTs

What UIs do I need to create?

There are a few flows you'll want to create and then a handful of optional ones you'll want to think about depending on your use case.


  • NFT Balances
  • NFT Details
  • Withdrawals


  • Crypto Balances
  • Transaction History
  • Deposits

Why do you need a digital wallet?

It seems like companies everywhere are getting into new digital markets, blockchain, crypto, and NFTs. One of the largest aspects of this new technology includes custody of these digital assets. There are products on the market now that accomplish this, but they usually require some extensive knowledge of blockchain tech, different chains and protocols, gas volatility, etc, while also redirecting the end-user away from your product to a third party source. This complexity mixed with redirection disrupts a seamless flow for the end-user, often coming off as convoluted and confusing.

With Fortress Wallets, the complexity is abstracted as we handle things like key/seed phrase management, gas costs, and extensive security including MPC. The white label nature of our APIs also means that you can keep the end-user engaged with your application and product, while seamlessly leading them through a simple end to end flow. With this simplified version of custody, you can now reach a much broader audience.

Supported Assets

Note: These are our default assets supported for our embeddable wallets. This table may be different from our other products for asset custody (Trust Api Product).

When our system detects an incoming deposit of an ERC20/BEP20 token that is not already
supported by our Wallet API, we will automatically add support for that token.
