G Wallet

The product

G Wallet is a Stellar-based mobile wallet and decentralized exchange that combines digital-asset management and trading in one application.

I contributed to G Wallet as part of the engineering team at KryptoMind. My work centered on developing the React Native mobile application and connecting its functionality with the wider platform.

The product used React Native for mobile, React.js for web interfaces, NestJS for backend services, MongoDB for application data, and AWS for cloud infrastructure. Stellar provided the blockchain foundation for the wallet and exchange functionality.

G Wallet is included in the active project set as a documented team contribution. The exact modules I owned are not fully recoverable from the public record, so the page distinguishes my reported contribution from the complete platform scope.

Purpose

G Wallet brought Stellar wallet and decentralized-exchange capabilities into a mobile experience, allowing users to access digital assets and trading functionality through the same product.

The platform connected user-facing interfaces with blockchain interactions and supporting backend services. Its development required coordinating the mobile experience, application data, authentication, and Stellar integration.

Stellar wallet and XLM

The wallet was built around the Stellar ecosystem, including XLM, Stellar’s native asset.

This formed the blockchain layer of the product, connecting the application’s wallet experience with the underlying network.

My contribution focused on the mobile application within this broader system, helping the team deliver an interface for the product’s blockchain functionality.

Decentralized exchange

G Wallet included decentralized-exchange functionality alongside its wallet.

The product brought asset management and trading together through a shared application experience. The DEX was a core part of G Wallet’s purpose and product identity.

React Native mobile application

The Android and iOS applications were built using React Native.

I contributed to the mobile codebase as part of the development team, working on application functionality and its integration with supporting services.

The mobile work involved bringing the product’s wallet and trading capabilities into a cross-platform interface while accounting for Android and iOS requirements.

React.js web interfaces

React.js formed the web frontend layer of the platform.

The web interfaces complemented the React Native application. Together, these frontend technologies connected users with the platform’s backend and blockchain functionality.

NestJS backend

The backend used NestJS running on Node.js.

This layer provided supporting application services and business logic, connecting the frontend interfaces with application data and blockchain-related integrations.

The backend formed part of the wider system that the mobile application communicated with.

MongoDB data layer

MongoDB supported the platform’s application-data requirements.

It served as the database for supporting application functionality alongside the Stellar blockchain integration. The architecture combined conventional backend data storage with blockchain-based wallet and exchange capabilities.

AWS infrastructure

AWS formed part of the platform’s cloud infrastructure, supporting its backend environment.

The project brought together mobile and web clients, backend services, database storage, and blockchain connectivity within this architecture.

Biometric authentication

The mobile application included biometric authentication as part of its access experience.

This introduced device-based authentication alongside the wallet and exchange functionality, making native mobile capabilities part of the product.

Team collaboration and delivery

I worked on G Wallet as a contributor within the KryptoMind engineering team.

My involvement included React Native development and collaboration on integrating the mobile application with the rest of the platform. I also supported mobile delivery for Android and iOS.

The project required coordination between application interfaces, backend services, and blockchain functionality.

Technology stack

My responsibilities

• Contributed to G Wallet as part of the KryptoMind development team.
• Developed functionality within the React Native mobile application.
• Helped connect the mobile experience with supporting platform services.
• Contributed to the delivery of a Stellar-based wallet and decentralized exchange.
• Collaborated with engineers working across the wider application stack.
• Supported Android and iOS application delivery.

Key engineering challenges

The project required connecting a cross-platform mobile interface with wallet functionality, decentralized exchange flows, backend services, and the Stellar network.

Supporting Android and iOS meant maintaining consistent behavior across two mobile platforms while working with native capabilities such as biometric authentication. The mobile application also needed to coordinate account access, application data, and blockchain-related interactions.

The wider product combined React Native mobile interfaces, React.js web interfaces, NestJS services, MongoDB, AWS, and Stellar. Working as part of the team required keeping the mobile contribution aligned with those connected layers.

Delivered contribution

I contributed to a Stellar-based wallet and decentralized exchange across the React Native mobile application, helping connect digital-asset management and trading functionality with the wider web, backend, database, and cloud platform.

G Wallet reflects my experience contributing to a blockchain product across mobile development, platform integration, and Android and iOS delivery.
