About the client

A blockchain gaming company developing a crypto payment gateway integrated with Binance Smart Chain (BSC) to enable seamless minting, transfer, and management of fungible tokens (BEP-20) and non-fungible tokens (BEP-721) as in-game rewards and assets.

Objectives

• Develop a scalable and secure crypto payment gateway supporting minting, deposit, and withdrawal of BEP-20 tokens and BEP-721 NFTs.
• Implement smart contracts compliant with BEP-20 and BEP-721 standards, ensuring full functional coverage and integration with backend services.
• Enable multi-signature (MultiSig) transaction signing for enhanced security.
• Ensure seamless interaction between backend systems and blockchain, including event analysis, notifications, and operation verification.
• Provide a robust interface and webhook system for real-time operation status updates.
• Support game-specific business logic such as issuing NFTs as rewards and handling tokenized in-game assets.

Solution

We designed and implemented a modular crypto payment gateway architecture with the following key components:

• Mint Service: Automated token and NFT minting triggered by backend events under predefined conditions.
• Smart Contracts: Developed on Solidity (version 0.8+) using Hardhat, covering BEP-20 and BEP-721 standards with 100% unit test coverage in TypeScript.
• MultiSig Transaction Signing: Implemented a secure multi-signature signing method to authorize blockchain transactions.
• Event Analysis & Notification Service: Real-time monitoring of blockchain events, triggering notifications via webhook integrations.
• Backend Integration: Trusted backend services handle balances and operations, while smart contracts process minting, deposits, and withdrawals without direct access to user wallet balances.
• Scalability: Separate wallets for tokens and NFTs with support for high-volume operations and smooth scalability.

Key Results

• The gateway enables secure and scalable handling of crypto assets tied to gaming rewards, improving user engagement and monetization opportunities.
• Automated minting and withdrawal processes reduce manual intervention and operational overhead.
• Integration with Binance Smart Chain provides low latency and high throughput, enhancing user experience.
• MultiSig signing improves security, significantly reducing risks of unauthorized transactions.
• Modular microservice architecture allows for independent feature upgrades, reducing development time and costs.
• The platform supports potential token capitalization and exchange listing, adding long-term value for the client.

Lansoft team worked closely with the client from the very initial stages, assisting with the evaluation and prioritization of their business needs, as well as with the creation of a
technology for gathering roadmap requirements, analysis and documentation.

We also helped with the product’s UX and UI design, conducting manual, automated, load and security testing of the platform’s continuous deployment, maintenance and support. In the following 3 years, we’ve been refining the product and adding new features to it.

Our team developed a convenient Metazon platform where users can view all the available collections, information about creators & owners of it and terms of purchase. We also integrate a crypto wallet like MetaMask or any other similar wallet to transfer and store cryptos & NFTs.

We add VR galleries to virtualize clients’ exhibitions. They can easily create VR exhibitions and
showcase your artworks.

Lansoft team build a desktop web application with the possible mobile-view mode.

We also made website localization in which web content was adapted for consumption by a specific audience.
 It involved translation into English, Chinese and Arabic, as well as formatting and usability alterations and a consideration of particular cultural likes and dislikes.

Now, we are responsible for maintaining all app versions.

Lansoft team ensured smooth and safe transition to a new technology stack, optimized credit risk analysis module, implemented and tested new functionality and automated manual processes on tax calculations. 

Our team organized effective networking & mentorship platform for health & life sciences experts to fast track innovations and validate ideas with peers, doctors and scientists

A centralized portal to access all your healthcare needs.

Industry: Corporate development

Performalise is a Web platform designed to assess employees’ body of knowledge with a view to reveal and make use of their potential

Our goal was

Firstly, to deliver a product that would meet our customer’s requests 

Secondly, to set up continuous deployment processes

To get there we performed

• requirements collection, analysis and documentation writing

• UX/UI design and development

• design of the architecture 

• product development (TDD) 

• introduction of blue-green deployment

• automated, load and security testing

Some of the features:

• registration as Admin, Company manager or Employee and profile management

• Single sign-on authentication 

• Gamification and Top-notch UX interface 

• Analysis and visualisation of Big Data

• Swift (under a minute) updates that are absolutely unnoticeable to users

• Integration with Google sheets and Pluralsights
