Back End Web Development

Before we dive further into the deep in crypto specificity, let us explain the role of the back end in web development for the Web3 domain: how to build reliable systems that process data, transactions, and interact with blockchain and cross-chain protocols. Our team combines secure practices and scalability to control cost and quality. We specialize in web development for projects, focusing on decentralized systems and future trends. We work with developers who create solutions for users and businesses, integrating smart contracts, wallets, and centralized servers, as well as decentralized networks in blockchain projects.

Back end web development

Our approach to back end website development is based on a clear architecture, coding standards, and a transparent process: from requirements and analysis to testing and deployment. The backend, as a layer, is responsible for logic, data storage, authentication, event listening, and synchronization. For Web3 projects, we integrate blockchains (Ethereum, Polygon, Solana), self-executing contract scenarios, consensus mechanisms (proof of stake), and indexing. Such a back end is stable and extensible for web projects. We also use Rust specifically for backend development, which is not a common practice in projects, but based on our many years of experience, this approach is worth implementing.

Approach to back end tools for web development

In practice, we use back end software for web development and frameworks: Hardhat, Truffle, ethers, and The Graph. We connect IPFS and Arweave for storage, integrate payments, and monitoring. Such a stack helps to build and deploy contracts, interact with them while adhering to decentralisation principles, and without losing productivity in production.

Concepts and stack

To explain the back-end value in web development, we decompose the backend into subsystems: security, interoperability, multi-chain routing, and external integrations. We combine traditional centralized approaches with decentralized alternatives, allowing us to scale solutions without losing control. This is critical for web development in connection with blockchain.

Node is widely used in back end web development

We use Node for back-end development for rapid prototyping and data processing in production when integration with blockchain, queue systems, and blockchain events is required. It is convenient for APIs that work with smart contracts, use libraries to interact with nodes and provide secure transactions and a transparent process in production.

Security, scalability and cost

We adhere to security practices: encryption, secrets management, role-based control, audit trails, and integration checks with blockchain. For scalability, we use horizontal scaling, queues, caching, and event-driven mechanisms that strengthen the system under load. If necessary, we offer white label modules, explain the rationale behind the chosen approach for stakeholders, and transparently estimate the cost: features, compliance, integrations, projected load, geography, and support. This also simplifies back end support.

Integration with blockchain

We connect blockchain as part of business logic: smart contracts, tokens, consensus, cross-chain, and wallet-based interaction. We use querying and indexing to synchronize dapp events, process transaction data, and optimize flows. This approach allows us to build truly transparent systems that maintain decentralization principles and preserve trust.

Delivery process

Our development process: discovery, design, implementation, testing, deployment, and support. We integrate back end into projects for creating web solutions and automate CI/CD. For Web3, this includes nodes, event subscriptions, secure key management, and integration with external services. Such solutions are used both for startups and for improving existing projects in order to enhance integration and further scaling into the ecosystem. We believe that this approach will make both the client, who will not experience any crashes at the most inopportune moments (at a conference, for example), and the developer, who will be responsible for further support of the project, happy.
