Custom Blockchain Application Development

Blockchain application development goes beyond cryptocurrencies and involves building decentralized applications (dApps) or enterprise systems for prominent sectors like healthcare, finance, and supply chain utilizing the transparency, security, and immutability of distributed technologies. 

Unlike traditional apps that rely on a central server, these applications record tamper-proof data across a peer-to-peer network. In today's market, this often includes integrating smart contracts to automate business logic without the need for intermediaries or centralized control. 

Depending on your business goals, the four primary architectures are described below:

• Public Blockchain: As the name suggests, these are completely decentralized and open to anyone (e.g., Ethereum, Solana). Ideal for building trust in open ecosystems.
• Private Blockchain: As it's a confined ecosystem, it is restricted to a single organization. These offer high speed and privacy, making them perfect for internal corporate databases.
• Consortium Blockchain: The oversight and governance lie with a group of organizations rather than one. It is common in supply chains and banking, where multiple partners must collaborate securely.
• Hybrid Blockchain: A "best of both worlds" approach that keeps some data private while allowing other parts to be publicly verifiable. 

If you're moving ahead with a custom blockchain application development, based on our current market research, here's a tiered pricing structure based on complexity:

• Basic MVP (Proof of Concept): $25,000 – $60,000. focusing on core ledger functionality and simple smart contracts.
• Standard Business Solution: $60,000 – $150,000. including custom UI/UX, multi-user roles, and standard security audits.
• Enterprise-Grade Platform: $150,000 – $350,000+. featuring high-security compliance (HIPAA/GDPR), AI integration, and multi-region scaling.

While these are generalized estimates, costs vary greatly based on the chosen network (e.g., Gas fees on Ethereum vs. low-cost Layer 2s), project goals, and features. For a detailed estimate, scope, and timeline, please schedule a free consultation with the Proquantic team. 

Absolutely. You don't always need to build from scratch. We take a complete architectural audit of your digital ecosystem. We use secure APIs, middleware, and oracles (like Chainlink) to connect your current legacy systems with decentralized networks, without disrupting your workflows. This allows you to add features like immutable audit trails or automated crypto-payments to your existing ERP or CRM without a total overhaul. 

The timeline for blockchain application development depends on project scope and complexity. We are sharing below a market-researched estimate of the development timeline. 

• Discovery & Design: 2–4 weeks to define requirements, architecture, and user experience.
• MVP Development: 3–5 months to build core features and validate the concept.
• Full-Scale Enterprise Deployment:  9–14 months. Add an extra 3-6 weeks for smart contract auditing, which ensures the system is fully secure before launch.

Yes. We offer staff augmentation services, and you can choose from flexible models based on your requirements. Our hiring process helps you get started quickly by choosing from a pool of pre-vetted senior blockchain engineers, smart contract auditors, and DLT architects. Once onboard, they work as part of your in-house team. This is a cost-effective way to scale your technical capabilities quickly without the long-term overhead of full-time hiring.
