Vault: Assisted Self-Custody for Crypto

Uphold’s Vault is the first assisted self-custody solution integrated with a major digital asset trading platform. 

As a crypto user you no longer have to choose between the enhanced security of a self-custodial wallet, and the convenience of a centralized exchange – Vault offers the best of both worlds.

Here’s everything you need to know to get started with Vault.

What Vault Offers You

Vault lets you retain full control of your digital assets, while enjoying the best of centralized convenience and decentralized control.

With Vault you get:

  • A Multi-Signature Wallet: You have exclusive control over the funds in your Vault. You hold two of three keys, maintaining full control. The key held by Uphold simply co-signs user-initiated transactions on the platform and the key replacement service.
  • Key Replacement: Traditionally, if you lose your private key, you lose access to your funds. With Vault, you can initiate a key replacement that will enable you to recover access to your assets. 
  • Global Trading: Seamlessly move assets from your Vault to the Uphold platform and execute trades 24/7.
  • Full Accessibility: If you ever lose access to the Uphold app for any reason, you can always move your funds via the Vault Assist Tool.
  • A Cost-Effective Solution: We believe that convenient, feature-rich digital asset management tools shouldn’t only be available to users with large holdings. That’s why Vault was designed to be accessible for everyone.

How Vault Keys work

Every Vault is a 2/3 multi-signature wallet, with two of these keys are held by the user, and one is held by Uphold:

  1. Vault Key (user-owned): Your Vault Key is stored both locally on your mobile device and optionally backed up to the cloud (either iCloud or Google Drive, depending on your device).
  2. Backup Key  (user-owned): A 12-word seed phrase used with your Vault Key to access your funds on-chain (via the Vault Assist Tool). It is also needed to help replace your Vault Key.
  3. Uphold Key (held by Uphold): A key that allows Uphold to co-sign and authorize user-initiated transactions. These transactions can either involve moving funds helping replace a lost or compromised key.

Under this configuration, it takes two keys to move funds within a Vault. Only you, the Vault owner, have the ability to move or manage your assets without third-party intervention. In other words, Vault  is “bankruptcy remote”, meaning you can move your Vault funds whenever you wish without Uphold ever needing to co-sign a transaction. 

At the same time, this multi-sig configuration makes it possible for you to replace a missing key and avoid being locked out of your Vault.

How does Vault’s Key Replacement Work?

There are countless stories of people losing the keys to their wallets leading to the irrevocable loss of their cryptocurrency holdings. Vault’s Key Replacement Service allows you to avoid this and ensure seamless, uninterrupted access to your funds even if you lose one of your private keys.

In the event your Vault Key or your Backup Key is lost or compromised, Uphold can help replace it in combination with your remaining key, thereby restoring access to your funds. The Uphold Key can only be used to help replace one of your lost key or co-sign transactions you initiate. At no point during the key replacement process does Uphold have access to your Vault assets or your private keys.
