Dapper Self Custody

Dapper Self Custody - Beta Test

Thank you for helping us test Dapper Self Custody. Built exclusively for mobile devices, Dapper Self Custody is a great new option for quickly connecting a digital wallet to your dApp. This wallet can store both fungible and non-fungible tokens, facilitate frictionless transactions to and from other Flow wallets, and grant users complete control over the ownership and portability of their digital assets.

Some important notes on the Dapper Self Custody beta test:

  • Testnet - During the closed beta, Dapper Self Custody is only functional on Testnet.
  • Backup and Recovery - Backup and Recovery is still in active development. It is enabled on iOS and disabled on Android. Subsequent updates will evolve backup and recovery and enable it for Android. Please keep in mind that all wallets created in the beta phase are on Testnet.

Getting Started

Step 1 - Sign Up for the Beta

If you haven’t already done so, sign up for the Dapper Self Custody beta here:

Step 2 - Install Dapper Self Custody

Once invited, you should receive an invite e-mail from either TestFlight (iOS) or Firebase (Android). Accept this invite and follow its instructions to install Dapper Self Custody on your mobile device.

Step 3 - Create Your Wallet

In Dapper Self Custody, log in to your Dapper account and follow the prompt to create a new self custody wallet on Testnet.

Step 4 - Play Flow Rider


We’ve created a sample dApp called Flow Rider to show you how Dapper Self Custody works. Now that your wallet is ready, let’s collect some tokens!

  • Go to Flow Rider using your desktop’s web browser
  • 💻
    At this phase, the test focuses on using Flow Rider on desktop web. We’re actively working on a native mobile sample dApp as well.
  • Connect to Flow Rider - Connect to Flow Rider using the Dapper Self Custody app by clicking the Connect to dApp button. Scan Flow Rider’s presented QR code with Dapper Self Custody.
  • Fund Wallet - Once connected, follow the instructions within Flow Rider to fund your new self custody wallet with FLOW if you haven’t already done so.
  • Sign Transactions - While you’re playing Flow Rider, you’ll be presented with pop-up screens in Dapper Self Custody asking you to sign transactions. Confirm these transactions inside the Dapper Self Custody app.
  • Earn Flow Rider Gems as you play - Your Flow Rider Gem count is reflected in both Flow Rider and Dapper Self Custody. At the bottom of Flow Rider, you’re able to “spend” these gems exemplifying a token purchase transaction.

Step 5 - Give Feedback

While testing Dapper Self Custody, you can take a screenshot within the app—this will bring up the “Need help?” screen where you can report a bug, ask a question, or suggest an improvement. Feedback given through this in-app prompt goes straight to the team building Dapper Self Custody. We’re incredibly excited to evolve Dapper Self Custody beyond this simple starting point and your feedback is incredibly valuable on that journey.


Developing for Dapper Self Custody

Dapper Self Custody uses WalletConnect 2.0 to form connection between a dApp and the wallet. Once a connection is formed, the dApp is able to inspect the wallet’s public address and request a transaction to be signed by the wallet. Building for Dapper Self Custody requires a dApp to integrate WalletConnect 2.0 via FCL. The following sections will get you started building WalletConnect 2.0 support into your Flow dApp.

Create WalletConnect Project

Before implementing WalletConnect 2.0 into your project, you first need to obtain a WalletConnect projectID. First visit the WalletConnect Cloud Registry:

Once logged in, select New Project.


Add details for your new WalletConnect project:


This will give you a projectID for WalletConnect which you’ll utilize in your project.

Integrate FCL, WalletConnect

Now that you’ve created your WalletConnect project and have your projectID, follow the instructions below to add support for FCL compatible wallets that use the WalletConnect 2.0 protocol - which includes Dapper Self Custody.

Example dApp

The following Github repo is a React project that implement FCL WalletConnect as described above. It exemplifies how to connect to a WalletConnect supported Flow wallet like Dapper Self Custody and how to send a transaction request.
