People are talking about Web3 and decentralization all over the place today. Under the wave of emerging concepts and capital flows, more developers and users are pouring into Web3, and the number of commits per project skyrocketed. For those considering getting into Web3, the first course they must master is undoubtedly the crypto wallet.

One of the origins of Web3 is the transparency and privacy of data storage, building trust in 'trustless' communities. Ideally, we can see blockchain governance as a database, in which the standard operating procedures are granted the highest authority. In such a setting, all data recorded on the blockchain is publicly available and cannot be altered, guaranteeing fidelity and security of personal data without the need of a trusted third party. Some blockchains also need special permission to read, access, and write information.

Early crypto wallets emphasized giving users complete control over their digital assets, so they have to memorize the seed phrases, which are not designed for novice users' needs. Though a lot has changed in the past decade, as wallets become easier than ever to securely store and transfer your cryptocurrency, barriers to adoption still exist.

For example, a time-consuming step to create the wallet might cause a significant loss of users. As many projects came to awareness of the problem, they started developing a variety of onboarding solutions to seamlessly buy, sell, and trade NFTs directly, blurring the boundaries between Web2 and Web3 users. Under the user's permission, the wallet can also verify the identity through proof of ownership, of which Twitter's NFT profile pictures are among the first attempts.

We believe that the next big step is Web2 integration into Web3 ecosystems. The two, however, have to co-exist for a very long time, leaving a few years for Web3 to transform the internet into a better version of itself and improve the user experience in payment and asset custody to a large extent.

How Does Mirror World SDK Collect User Information?

Mirror World SDK integrates with all types of traditional login methods (Google, Discord, Twitter, Email) and builds wallets that allow users to fully manage their crypto assets. With our wallet service, developers do not need to worry about how to store and manage private keys securely. We have done that job for you.

Concerning different scenarios, Mirror World SDK offers several plans to meet developers' needs:

High-Frequency Trading

Take early Web3 games, for example, most of them primarily focused on play-to-earn, galvanizing pre-existing incentives to play games with a financial component. Even though people can be shortly immersed in strong Fomo emotions by achieving a massive return, it is hard for the game to become sustainable once the number of new users starts to drop.

Following the expanding market, more blockchain projects have now shifted to creating content comparable to traditional gaming and developing user coordination models with in-game economies. Players can thus unlock access by gathering resources and claiming roles. However, behind those frequent, ongoing transactions, each change in token is directly linked to the blockchain, resulting in a high cost of the gas fee. Since all on-chain data needs to sync to network nodes, the waiting time may lead to a poor user experience (Imagine if a user wants to upgrade the equipment, which takes over 1 minute and is likely to fail).

In light of such concerns, Mirror World SDK also provides smart contract support that automatically executes outcomes when certain predetermined criteria are met. With low development costs, users can easily enable transfers of digital assets via smart contrast, all of which will be recorded when the deal is settled.

General Usage

When developing Mirror World SDK, we found that most decentralized applications face the problem of how to employ direct interaction between users and the blockchain network. Before, mobile users would interact with web apps from the in-app browser. While this method works well for web applications running on desktop browsers, it often leads to a decline in users by driving all traffic to third-party apps.

To tackle this issue, Phantom earlier announced a new way for developers to integrate Phantom into their iOS and Android applications through either universal links or deeplinks, with which developers can now seamlessly integrate Phantom across all devices and environments instead.

Likewise, Mirror World SDK is one of the first to integrate deeplinks, allowing developers to query on-chain data directly if needed. The deeplinks, however, might not be the best solution from a user's perspective, as you have to open other web apps, sign the transaction, and then return to the native app each time.

What Mirror World crypto wallet does is simplify the process above. Having all-in-one authentication and mobile in-app integration enables NFT assets purchase with fiat currencies and mainstream cryptocurrencies in your own marketplace. All users have to do is enter the password and wait for the system to process.

How Does Mirror World Secure Your Crypto Wallet?

Knowing that securing users' assets is crucial in developing an SDK, the Mirror World team discussed a wide array of solutions for its framework. Eventually, we reached our current Crypto Wallet Version 1.0.

To ensure the safety and confidentiality of users, we use a combination of the following two approaches:

1. The user's private key never leaves our cloud infrastructure. Key generation, encryption, decryption, and storage are all happening in the cloud. The overall process is never exposed to the external.

2. The user's key is encrypted by the third-part KMS (Key Management System). We do not store the plain-text private key. Instead, only the encrypted key is stored in our backend. A trustable third-party KMS provider does encryption with strict access control policies to protect the data encryption data. More importantly, the encryption key never leaves the KMS.

Set Up Mirror World SDK : Low Code and Faster Speed

With just a few lines of code, you can successfully access the Mirror World SDK, which has been used in two of Mirror World's own games: Mirrama and Brawl of Mirror. You can set up a developer account now and create a project to generate API Keys. After installing the SDK and configuring default settings in just a moment, your project will be good to go!

In the future, we will continue updating the crypto wallet for a better user experience. If you are interested in learning more about Mirror World SDK, please check the links below:
