Anchorage Digital supports interactions with a growing list of decentralized apps (dApps) through the Anchorage Browser Extension and WalletConnect. Administrators control which vaults are enabled to interact with each app and can monitor all connection activity within their account.

<Note>
  Anchorage Digital iOS app version 2.41.0 or later is required to use approved apps in the Web3 portal.
</Note>

## Why Web3 access matters

A **smart contract** is a program that runs on a blockchain — it holds funds and executes rules automatically, with no intermediary. A **decentralized app (dApp)** is the interface to one or more of those contracts. Together they're how a growing share of institutional activity now happens on-chain.

For an institution, that's where real use cases live:

* **Tokenized assets and redemptions** — for example, redeeming BlackRock's BUIDL fund for USDC through Securitize (walked through below).
* **DeFi** — lending, borrowing, providing liquidity, and swapping assets directly with on-chain protocols.
* **On-chain governance** — voting on protocol proposals for assets you hold.
* **Restaking and staking protocols** — interacting with contracts like EigenLayer.

Connecting a wallet to a smart contract carries risk: an approval granted to a malicious contract can move funds. Anchorage Digital applies custody controls to these interactions: administrators approve which dApps each vault can connect to, connections run through the Anchorage Browser Extension or WalletConnect, and **every on-chain action requires quorum approval and Anchorage Digital review** before it executes.

## Getting started

<CardGroup cols={2}>
  <Card title="Chrome browser extension">

  </Step>

  <Step title="Manage existing apps">
    Click on any app in the **Approved apps** list to edit vault access or remove the app from your organization's approved list.
  </Step>
</Steps>

## Chrome browser extension

The Anchorage Digital browser extension connects your Anchorage wallets directly to decentralized apps (dApps). It serves as the institutional bridge between your Anchorage wallets and Anchorage-approved dApps.

### Downloading and logging in

<Steps>
  <Step title="Download the extension">
    Download the [Anchorage Digital browser extension](https://chromewebstore.google.com/detail/anchorage-digital/fadcgekaahkbmhjnpdhldednpbfpmkfl) from the Chrome Web Store.
  </Step>

  <Step title="Open the extension">
    Open the browser extension in Chrome.
  </Step>

  <Step title="Scan the QR code">
    Open the Anchorage Digital iOS app and tap the **QR Code** icon. Scan the QR code displayed in the browser extension.
  </Step>

  <Step title="Confirm access">
    Review the location of the device requesting access and allow access from the iOS app.
  </Step>
</Steps>

### Finding approved apps

In the **Explore** tab, the first section shows all apps your organization administrator has approved. Click on any app icon to open it in a new tab.

<Info>
  If an app has not been approved by your administrator, you cannot use it until they configure the allowed vaults and accept the Terms and Conditions on the web dashboard. Contact your administrator or reach out to your client experience manager to request certification of additional apps.
</Info>

  </Step>

  <Step title="Connect">
    Select **Connect** in the top right corner of the app.
  </Step>

  <Step title="Select Anchorage Digital">
    Choose **Anchorage Digital** from the list of wallet options. If you do not see Anchorage Digital listed, contact your client experience manager.
  </Step>

  <Step title="Find your wallet">
    Filter by vault or select a recently used wallet. Select the wallet to view its details and balance information.
  </Step>

  <Step title="Finish connecting">

## BUIDL redemptions via Securitize

Securitize manages digital securities and serves as the transfer agent for BUIDL, a money market fund managed by BlackRock. Anchorage Digital users can interact with the Securitize dApp via WalletConnect to redeem BUIDL for USDC.

### Overview

A completed BUIDL redemption triggers:

* A withdrawal of BUIDL from your Anchorage Digital wallet
* A deposit of USDC into your Anchorage Digital wallet
* The counterparty is always Circle
* The source is always the same smart contract

### Who can use the Securitize dApp

Users who hold BUIDL on Anchorage Digital and are onboarded with Securitize can use the dApp. Only an authorized user with Securitize credentials can initiate a redemption.

### Step 1: Connect Securitize to your account

<Steps>
  <Step title="Log in">
    Log in to your Anchorage Digital account that holds BUIDL in custody.

  </Step>

  <Step title="Select Securitize">
    Select **Securitize** from the app dropdown.
  </Step>

  <Step title="Choose vaults">
    Choose the vaults holding BUIDL that you want to connect.
  </Step>

  <Step title="Add to allowlist">
    Add Securitize to the allowlist and accept the app terms.
  </Step>
</Steps>

### Step 2: Select and prepare your wallet

<Steps>
  <Step title="Open your BUIDL wallet">
    Open the wallet holding your BUIDL.
  </Step>

  <Step title="Ensure sufficient ETH for gas">

  </Step>

  <Step title="Fund with ETH if needed">
    If the balance is insufficient, fund your wallet with ETH before proceeding.
  </Step>
</Steps>

### Step 3: Approve a redemption amount

New users must approve a redemption amount before proceeding. Returning users can skip this step if an approval is already in place.

<Steps>
  <Step title="Open the Securitize app">
    Navigate to the Securitize app in your browser.
  </Step>

  <Step title="Connect your wallet">
    Go to **Wallets**, then **Connect Anchorage Digital wallet**. Scan the QR code using the scanner in the top-right corner of the iOS app.
  </Step>

  <Step title="Submit the conversion operation">

  </Step>

  <Step title="Complete risk review">
    * **Quorum approval:** Users with the correct permissions must endorse the approval in the iOS app.
    * **Ops review:** Anchorage Digital performs a risk review of the transaction.
  </Step>
</Steps>

### Step 4: Redeem approved amounts

Once an amount is approved, you can proceed with the redemption.

<Steps>
  <Step title="Submit the redemption in Securitize">
    Select **Sell for USDC**, specify the amount, and click **Sell**.

    * **Ops review:** Anchorage Digital completes a back-office approval.
  </Step>
</Steps>

### Step 5: View updated balance

Once completed, the redeemed USDC will appear in your Anchorage Digital wallet within 5–10 minutes.
