Currently, the crypto wallet market is full of various types of solutions. From hardware wallets, software wallets, mobile wallets, to recently embedded wallets in web applications, users have a wide range of options to choose from according to their needs.
However, this diversity is creating new challenges:First, the issue of consistency in user experience. The reality of having to use different wallets on various platforms and applications can be confusing for users.Second, security issues. Having to manage multiple wallets can complicate the management of private keys or seed phrases, increasing security risks.Third, the issue of interoperability. Asset transfer or function linkage between different wallets may not be smooth.
1.2. Definition of Embedded Wallets and Branded Wallets
Against this background, the concepts of embedded wallets and branded wallets are gaining new attention in the industry.
Embedded wallets are wallets built into specific applications or services, allowing users to manage digital assets within the service without installing a separate wallet. They greatly improve user experience and contribute to lowering the entry barrier to Web3 services.
On the other hand, branded wallets refer to wallets provided as independent applications, such as MetaMask, Rabby Wallet, Phantom, and Coinbase Wallet. These offer richer features and wider compatibility and are widely used in the crypto ecosystem. Branded wallets support various blockchains and DApps, providing users with more control and flexibility.
Embedded wallets and branded wallets each have their own advantages and disadvantages. Embedded wallets are convenient to use and highly accessible, but may have limitations in functionality or be dependent on specific services. Branded wallets provide extensive functionality and compatibility, but may have entry barriers as users need to install and manage them separately.
In this situation, the crypto industry is contemplating how to effectively integrate and complement these two types of wallets. It's an important task that can improve overall user experience, security, and accessibility to the Web3 ecosystem beyond simply technical issues.
2. The Need for Crypto Wallet Integration

3. Embedded Wallets and Branded Wallets: 6 Integration Methods
Crypto wallet integration can be approached in various ways. Here, we briefly explain the main approaches to connecting or integrating embedded wallets and branded wallets.
3.1 Wallet Expansion through Key Replication
In this method, users start with an embedded wallet, replicate their private key or mnemonic phrase, and import it into a branded wallet like MetaMask or Phantom. The main advantage of this approach is that users can continue to use the embedded wallet even after replicating the key. It provides flexibility to users, allowing them to continue utilizing the functions of embedded wallets specialized for specific services or applications while also using the additional features of branded wallets.
However, this method has significant drawbacks. Directly handling private keys involves considerable security risks. Users must take full responsibility for key management, and there's a risk of losing all assets if the key is exposed or lost.
Moreover, for many general users, managing private keys can be a complex and burdensome process. Therefore, if this method is adopted, it's essential to provide user education and clear guidelines on safe key management methods.
3.2 Utilizing Universal Connection Protocols
In this approach, universal connection protocols like WalletConnect are added to embedded wallets to enable connections with various third-party sites. The advantage of this method is that users can access multiple services through a familiar interface.
It also provides connectivity to the broader Web3 ecosystem while maintaining the convenience of embedded wallets. However, this method also has some drawbacks. Users still need to manage multiple wallets, and the concept of universal connection protocols may be unfamiliar to some users. This could act as a barrier to new user inflow, thus requiring a clear and user-friendly onboarding process.
3.3 Seamless Asset Transfer Functionality
This method involves "exporting" assets from embedded wallets to branded wallets. The biggest advantage of this approach is that users can move assets quickly and easily. It can be particularly useful for users who start with embedded wallets and gradually need more complex functions. By moving from embedded wallets to branded wallets, users can access more diverse functions and dApps beyond the services where the embedded wallet is built-in.
However, the main drawback of this method is that the utility of the embedded wallet significantly decreases after asset transfer. This ultimately means that users may no longer be able to utilize the unique functions of embedded wallets associated with specific services or applications. Also, there's a risk of loss due to mistakes during the asset transfer process. This can be a significant burden, especially for users unfamiliar with cryptocurrencies. Therefore, if this method is adopted, it's important to design a safe and user-friendly asset transfer process.
3.4 Brand + Embedded Wallet
This approach involves embedded wallets also having some functions of branded wallets. As a result, users can log in to both embedded and branded wallets with the same credentials.
The biggest advantage of this method is that user-friendly authentication methods like email or social login can be used everywhere. This can greatly lower the entry barrier for Web2 users into Web3. Also, by providing a consistent user experience, it can reduce user confusion and increase overall satisfaction.
However, this approach comes with significant technical challenges. Implementing all the functions of branded wallets in embedded wallets can be a complex and time-consuming process. Also, compatibility issues with existing branded wallets may arise, potentially affecting interoperability with the entire ecosystem. Therefore, if this method is adopted, a long-term development plan and continuous maintenance strategy are necessary.
3.5 Connecting/Disconnecting Signers in AA Wallets
The method of connecting/disconnecting signers in AA wallets provides users with more flexible and powerful wallet management options. In this approach, users start with an embedded wallet equipped with Account Abstraction (AA) functionality.
The key to this method is that users can add other wallets, for example, branded wallets like MetaMask or Coinbase Wallet, as 'signers' to their AA embedded wallet. It's similar to adding a co-signer to a bank account. Through the signature of the added wallet, users gain the authority to view the assets of the embedded wallet and approve or execute transactions as needed.
The great advantage of this method is that users can flexibly connect and manage multiple wallets as needed. For example, users can use a simple embedded wallet for daily transactions and use an added branded wallet for approval of more complex or important transactions. Also, this connection can be disconnected at any time, securing both security and flexibility.
However, this approach also faces some challenges. The biggest issue is that not many wallets currently support this function. AA is a relatively new concept, and many existing wallets need significant upgrades to implement this function. Also, the concept and usage method of AA may seem somewhat complex to general users, requiring user education and interface improvements for widespread adoption.
3.6 Wallet Management through a Centralized Hub
In this approach, platforms like Farcaster track and manage multiple embedded wallets of users. The wallets are separate but all managed on one platform through a centralized profile.
The main advantage of this method is that users can effectively manage multiple wallets through a single interface. Also, by utilizing popular platforms like SocialFi, it can provide users with a familiar environment.
However, this approach may raise security and privacy issues due to high dependence on a centralized hub. Therefore, if this method is adopted, strong security mechanisms and user data protection policies should be implemented together.
