How to Use Multiwallet Linking to Build a Portfolio Dashboard
Ask most crypto users how many wallets they have and the answer is rarely "one." People keep a hot wallet for daily activity, a hardware wallet for long-term holdings, a separate address for a specific chain, and often a fresh wallet for each app they are cautious about. That is normal behaviour, but it breaks a common assumption baked into a lot of onchain apps: that one user equals one wallet.
If you are building a portfolio dashboard, that assumption is fatal. A dashboard that only reads the single wallet a user happened to connect will show a fraction of their real holdings, misreport their allocation, and quietly undercount everything you present back to them.
This guide walks through how to close that gap using Reown Multiwallet Linking. But before we get there, let’s dive into what a portfolio dashboard is and what types of apps they serve best.
What is a portfolio dashboard?
A portfolio dashboard allows users to view the activity in all of their wallets, with aggregated data on the total balances of coins and tokens they hold across multiple chains. It can also give deeper insights into onchain history across multiple wallets—whether they are hot wallets, smart wallets or hardware wallets. This gives users an easy way to track exactly where there funds are, where they’ve bridged or swapped funds to in the past and their overall onchain activity.
What types of onchain apps are portfolio dashboards useful for?
Portfolio dashboards help all sorts of apps that benefit from connecting multiple wallets. The most popular would be decentralized exchanges, so that users can access liquidity across multiple chains and wallets. But they are also used in many other types of apps, such as onchain analytics platforms for receiving in-depth data on users and their addresses, and even gaming platforms that rely on multiple in-app wallets across an ecosystem.
Why Multiwallet Linking is built for portfolio dashboards
A portfolio view is only as accurate as the number of addresses it can read. Reown Multiwallet Linking lets a single user connect multiple wallets to your app at the same time, switch between them, and manage those connections directly in your interface. It is available on all paid Reown plans—including Pro, Growth and Enterprise—and supported across React, Vue, and Next.js.

What Reown unlocks for portfolio dashboards
The full set of connected addresses
With multiwallet linking, you connect the data across multiple wallets into a single user profile, meaning you can verify aggregated holdings across every linked wallet.
Simple switches for active connections
Reown lets users choose which wallet should be active through the multiwallet linking hooks; useAppKitConnection and useAppKitConnections, so actions are always attributed to the right address. Reown also allows for simple network switching through pre-built modals. With these tools, users don’t just get to see an aggregated view of all wallets, they can switch between them to take actions with specific addresses at will.
Wallet connection data and history
Reown also provides important data on your user’s behaviour, such as how many wallets a typical user links and which wallet types and providers show up most, helping you shape the portfolio’s design and functions. These important pieces of data can be found in the Reown Dashboard’s analytics tab, along with a whole lot more that can help develop the user experience.

Multiwallet Linking: Providing the basis for powerful portfolio dashboards
A portfolio dashboard lives or dies on completeness. Reown Multiwallet Linking removes the single-wallet ceiling and handles connection, active-wallet context, and balance data through one integration.
And beyond that, Reown helps you build a powerful portfolio dashboard beyond multiwallet linkiing using pre-built switching modals and in-depth analytics. With the ability to provide multiple wallet connections and access whether engagement rises after a second wallet is linked, and which wallet types dominate your audience, you can design for the users you really have.
