SDEFI Case Study: Development of a secure and user-friendly crypto wallet

Onez White Label Wallet: SDEFI case

Table of Contents


SDEFI, a crypto company targeting Latin American markets, partnered with Onez for the development of their ecosystem. In the first phase, we decided to create a Web3 cryptocurrency wallet and an MVP version of a dex-exchange.

We supplied SDEFI with a secure web3 wallet solution using our white-label wallet platform, ensuring safe storage and smooth transactions of crypto assets. With a focus on security, we incorporated advanced mechanisms to deter hacking attempts and remove potential vulnerabilities. In addition to security, we created the wallet for both Android and iOS platforms, offering users a user-friendly interface to store, manage, and transact their cryptocurrencies.

Business requirements

The SDEFI aims to develop a comprehensive, decentralized mobile app to cater to diverse user needs. After analyzing these needs, we introduced a secure and innovative DeFi wallet. This user-friendly wallet simplifies transactions and manages digital assets. It features multi-portfolio management, dashboards, and support for various tokens and coins, staking, as well as cryptocurrency exchange and purchasing.

  1. Develop a non-custodial mobile wallet app to simplify the financial journey of users.
  2. Customize the white-label crypto wallet application to meet the SDEFI brand’s needs.
  3. The goal is to develop a mobile wallet for both Android and iOS platforms. This wallet will support BTC, ETH, LTC, and BNB (BSC), enabling instant cryptocurrency exchange and cross-chain swaps.
  4. Set up the application and host it on both the Apple App Store and Google Play Store.
  5. Create a Minimum Viable Product (MVP) for a decentralized exchange. The MVP will serve as a proof of concept for potential investors and early adopters.

Challenges we encountered

The wallet solution was developed to tackle several challenges, primarily aiming to give users full control over their funds, which was previously managed by third parties. The other issues that the SDEFI Wallet sought to address include:

  • Ensuring security is paramount in crypto wallet app development due to the risks of hacking and unauthorized access.
  • Maintaining platform compatibility can be difficult due to varying development frameworks, languages, guidelines, and security considerations.
  • It’s important to balance security with a user-friendly design, as complex interfaces can discourage users.
  • Integrating blockchain to support multiple cryptocurrencies is a complicated task because of differing technical specifications and protocols.
  • The app supports instant crypto exchange and cross-chain swaps.
  • Performance and scalability are crucial to ensure the wallet can handle user growth and adapt to evolving needs.
  • Adherence to legal and regulatory requirements is necessary, and these may differ by jurisdiction.

  5. Performance and ScalabilityThe app can swiftly process transactions, manage real-time updates, and handle large volumes of data efficiently. From the start of the project, there was a strong emphasis on optimizing app performance and ensuring scalability.
  6. Regulatory ComplianceOur team has ensured that the app adheres to critical compliance standards, including KYC (Know Your Customer) and AML (Anti-Money Laundering). These standards can be complex and require ongoing effort.
