# Billions Wallet

> Self-sovereign identity wallets for managing and verifying credentials on the Billions Network.

The Billions Wallet is a self-sovereign identity wallet for the Billions Network. Signing in derives a decentralized identifier (DID) from a cryptographic key pair, and every credential you claim is encrypted and stored under keys only you control. When a service asks you to prove something about yourself, the wallet generates a zero-knowledge proof on the spot: you decide what to share, and the proof confirms it without exposing the underlying data.

You can access the Billions Wallet from the **web** at [wallet.billions.network](https://wallet.billions.network) or through the [**mobile app**](/billions-wallet/mobile-wallet) on iOS and Android.

<Info>
  When the Web Wallet and the Mobile Wallet are signed in with the same account, credentials are synced — enabling effortless access across multiple devices.

## Credential Management

Credential management is the systematic process of creating, storing, protecting, rotating, and revoking digital credentials. The Billions Wallet handles this end-to-end — letting you claim, store, and present verifiable credentials that are privacy-preserving proofs about who you are, issued by trusted parties and verified on-chain or off-chain without exposing your underlying data.

## How to Claim Credentials

<Steps>
  <Step title="Open the Wallet">
    Visit [wallet.billions.network](https://wallet.billions.network) or open the Billions Mobile Wallet. Sign in with Google, Apple ID, or a crypto wallet.
  </Step>

  <Step title="Identity Loads">
    An identity wallet is derived from your account and any existing credentials are retrieved from encrypted cloud storage.
  </Step>

  <Step title="Browse Available Credentials">
    View the credentials available to claim.
  </Step>

  <Step title="Initiate Claiming">
    Select a credential and start the issuance flow. Depending on the credential type, this may involve a face scan (Proof of Uniqueness), document upload (Verified Human), or an OAuth connection (Email, Social Accounts).
  </Step>

  <Step title="Credential Issued and Stored">
    The issuer verifies the information and issues a signed credential directly to your wallet. It is encrypted and stored in cloud storage — ready to use in any verification flow without needing to be claimed again.
  </Step>
</Steps>

## Credential Storage

All credentials are encrypted and stored in cloud storage — accessible across multiple devices and serving as a reliable backup. Upon sign-in, an identity is derived and storage keys are generated from the authenticated account.

<Info>
  **End-to-End Encrypted Cloud Storage**

  * **Signature scheme:** ed25519
  * **Encryption:** AES256-GCM
  * **Access:** Only the user holding the storage keys can decrypt and access their credentials

  No credentials are stored in plaintext at any point. The cloud storage acts solely as a secure, encrypted repository — the decryption keys never leave the user's control.
