About the project

DeFi is a multichain wallet that allows users to securely swap, store, and send crypto and NFTs across 20 blockchains, including Bitcoin, Ethereum, Fantom, Arbitrum, Avalanche, and others. As a leading DeFi wallet development project, the product has been designed as a browser extension available on Google Chrome, Microsoft Edge, Opera, Brave, and Côc Côc Browser.

Being non-custodial, DeFi Wallet does not access users’ funds and does not store their seed phrases, passwords, or any other private information. This makes it a highly secure and reliable choice among DeFi wallet development solutions.

Its key features include permissionless cross-chain swaps, a single gallery for all NFTs, direct bridging of tokens within the wallet, staking, support for hardware wallets, including Ledger, and rock-solid security, verified by a Kudelski Security audit.

Our engagement

Our experienced developers joined an in-house team to help DeFi continuously improve the existing user interface, add sophisticated features, and build additional products.

Devico provided development of the browser extension, which is the core DeFi product, their web app, and a cross-platform mobile app. As part of our DeFi wallet app development expertise, we ensured that all of them offer the same functionality, including token portfolio, NFT portfolio, crypto and NFT swapping, transaction control, connection with dApps, new wallet creation, and import of existing wallets.

On the backend, we implemented a microservice architecture with the use of the GraphQL router that combines schemes generated by the services. Some of the key activities included:

  • Building blockchain indexers for real-time data collection and transaction processing while also adding data to a database and providing a unified API for receiving a balance.
  • Writing a Python-based third-party RTL, which is a service for collecting and updating metadata about tokens on different blockchains, enhances our decentralized finance wallet development expertise.
  • Building the Asset service using Node.js and Nest.js, whose goal is to provide the GraphQL router with an API for submitting data about tokens, their prices, metadata, etc.
  • Developing the NFT balance service, a crucial component of our DeFi wallet development services, to provide the GraphQL router with an API for submitting data about NFT balances with blockchain parsing and off-chain NFT metadata.

Challenges

Our front-end developers improved existing UIs and built new ones as part of our DeFi wallet development efforts. Their key challenges and deliverables included:

  • To display asset details in the Defi extension so that users can see data with the token price dynamics and understand the reason behind a total balance change.
  • To accelerate the web app development process with regard to the fact that the same components are used to realize different commands.
  • To build the Swap page of the DeFi wallet app development, enabling users to swap their tokens without registering on exchanges or sales platforms.
  • To build the Portfolio page where users of the Defi web app can monitor their assets and check a balance.
  • To implement smooth animations within the mobile app.
  • To find the best solution for listing within the mobile app because its content is mostly represented in lists (token list, NFT list, transaction list, etc.).
  • To find the best flow for the onboarding screens of the mobile app and implement it.
  • To build the NFT screen where users can interact with their NFT tokens.
  • To build the Asset Management screen so that users can easily manage assets within their wallets.

As a reputable DeFi wallet development company, we focused on ensuring a seamless, efficient, and secure user experience through advanced UI solutions.

Non-custodial

We never have access to your funds

Solutions

Our DeFi wallet development team was involved in several key areas to enhance the application’s functionality and user experience.

  • To get data on token price dynamics, we implemented integration with CoinGecko, which stores data about tokens and updates it once a day. A separate page was built to display the chart of token price dynamics with the ability to set a particular period. Users can also find useful data about their tokens there.
  • To accelerate the DeFi wallet app development process, we created the DeFi-UI component library. We defined components and API components to be included in the library, built them, integrated them with Storybook, covered them with tests, and delivered a set of ready-to-use UI components.
  • We built the UI of the Swap page in full compliance with the provided design. Additionally, we integrated an API, enabled data saving in a form using SessionStorage, and implemented transaction signing using Web3, ensuring a seamless decentralized finance wallet development experience.
  • Our developers built the UI of the Portfolio page by the provided design and integrated an API to ensure smooth functionality.
  • After a comprehensive analysis of all leading animation libraries, we selected Reanimated as it was the fastest and most suitable for the UI thread. We used the latest Reanimated-2 version to create NFT lists and Drag&Drop collections, as well as to display token prices within different timeframes in the token price dynamics chart.
  • To enhance UI and JS thread speed and ensure smooth animations during user interactions, we used FlashList, which operates 5-10 times faster than FlatList in React Native. This solution significantly improved performance across the app, particularly for Drag&Drop lists and swipeable lists, which were custom-built for optimal DeFi wallet development solutions.
  • We studied onboarding screens available on the market and defined the best flow for the DeFi wallet app development process, including wallet creation and import. We designed seamless navigation across the screens, built screen components, connected libraries to implement necessary functionalities, and integrated TrustWallet’s API to enable wallet creation.
  • For NFT management, we developed a dedicated screen where users can view their NFTs, retrieve data, filter NFTs by blockchain, name, contract address, collection name, and more, and organize them into collections.
  • By integrating the Assets API and using the react-native-pager-view package, we developed a high-performance Asset Management screen that enables users to display and manage their tokens efficiently. Features such as hiding/showing tokens and adding custom tokens to a wallet were also implemented, providing a comprehensive DeFi wallet development services experience.

Using our engineering expertise and adaptability, we helped DeFi create an advanced, secure, and robust multichain wallet powered by cutting-edge technologies, positioning us as an experienced DeFi wallet development company.
