Still, confused about multichain crypto wallets?

Here is a step-by-step guide to build multichain wallets.

What Is A Multichain Wallet?

A multichain wallet is a cryptocurrency wallet that supports multiple blockchain networks. It means that you can store, send and receive multiple cryptocurrencies or tokens in one wallet.

Unlike other crypto wallets that are compatible with only one token standard, these wallets support major token standards for user convenience.

For instance, you do not need to have Ethereum, Polygon, and BSC wallets separately. You can set up a multichain wallet supporting all these blockchains where you can store ETH, MATIC, and BSC tokens in one place.

In the era of web3 and Defi, multichain wallets are a boon. One robust multichain wallet is sufficient to access all Defi and web3 services.

A multichain wallet has two vital components. They are:

Passphrase: A multichain wallet does not have a private key. instead, it has a passphrase that acts like your password to access your wallet and tokens.

Wallet address: Each blockchain in a multichain wallet has its own wallet address. You can use that wallet address to send and receive tokens on that specific blockchain network.

Building a multichain wallet requires a high level of blockchain expertise and programming skills. That is why you need a reliable wallet development company that will build a multichain crypto wallet packed with user-friendly features tailored to meet your business needs.

Benefits Of A Multichain Crypto Wallet

Here are some notable benefits of a multichain crypto wallet app.

Multiple blockchain Accessibility

The biggest advantage you will get with a multichain wallet is that you can access multiple cryptocurrencies and tokens over different blockchains with ease.


A multichain wallet uses cross-chain bridges and cross-chain routers. The bridges allow you to transfer cryptocurrencies between two blockchain networks. While the router enables you to transfer between two or more blockchains.

NFT compatibility

Apart from storing and transferring major tokens, you can even store your NFTs in a multichain wallet.

So, this feature makes it quite useful for investors who are involved in all areas of web3.

Non-custodial Nature

Imagine having a digital wallet where you can store major tokens without worrying over private keys.

The biggest advantage of a multichain wallet is its non-custodial nature. Instead of private keys, you have a passphrase that is applicable for accessing tokens across all supported blockchain networks.

Ledger Connection

What’s more, you can even connect your multichain wallet with a hardware wallet or ledger. Hardware wallets are the most trusted digital wallet solutions for keeping your cryptocurrencies safe.

There are reasons behind the tremendous increase in the demand for multichain wallets. These advantages of multichain wallets give them an edge over other wallets.

How To Build A Multichain Wallet?

Building a multichain crypto wallet is not a cake walk. You need the perfect product ideation, bring together a development team, monitor the development process, and get ready for the launch.

Your work does not end here. You also need to plan marketing strategies to promote your wallet. Further, even after the launch, you need consistent technical assistance to ensure high performance and undisrupted functioning of your wallet.

Let’s be honest here. You cannot manage everything yourself. That is why you should get help from a wallet development company.

They have a team of highly experienced developers, coders, Q&A experts, and product managers to handle everything perfectly. Right from analyzing your wallet ideation to market research, frontend & backend development to deployment, they will assist you at every step. What’s more, they also offer post launch technical assistance to ensure quality functioning and timely upgrade of your wallet.

Here are 6 steps to build a multichain wallet with robust features and high security standards.

Step 1: Strategy

The first step in multichain wallet development is defining the strategy. This phase involves determining the number of users, market trends, and competitor analysis.

Additionally, you will choose a platform for your application and consider the cost, which depends on the complexity and features you want to integrate.

The development time for a wallet is typically between 4 to 6 months.

Step 2: Product Roadmap

Once you have defined the strategy, the next step is to create a product roadmap that outlines the development process in detail.

This roadmap emphasizes wallet requirements and sets delivery milestones.

If you are developing a mobile solution, it is crucial to have a skilled and experienced development team by your side.

Step 3: UI/UX Design

The success of the wallet application depends on user adoption and the benefits offered by its features. Therefore, the wallet must have interactive and intuitive interfaces to boost user engagement.

During this stage, mockups are created, and the style guide is applied to application wireframes. The prototypes are shared with clients for feedback and undergo modification to meet their expectations.

Step 4: Wallet Development

The multichain wallet development process can be divided into two parts: development platform and transaction mechanism. Choosing the right platform is crucial for the success of the project.

You can incorporate the mechanism of your choice to authenticate transactions.
