Frequently Asked Questions
Have questions? We have answers. Here are some of the most common inquiries we receive about Web3 development.
Web3 development involves building decentralized applications (dApps) on blockchain networks. Unlike traditional Web2 applications that rely on centralized servers, Web3 apps use smart contracts and peer-to-peer networks to enable trustless interactions, user data ownership, and transparent operations. It's the foundational technology for cryptocurrencies, NFTs, DeFi, and DAOs.
The cost varies significantly based on complexity, the chosen blockchain, features, and security requirements. A simple proof-of-concept might start around $25,000, while a full-featured DeFi platform or NFT marketplace can range from $100,000 to $500,000+. We provide a detailed, transparent quote after an initial consultation to understand your specific needs.
Security is our top priority. Our process includes secure coding practices from day one, multiple internal code reviews, and comprehensive smart contract audits by third-party experts. We also conduct penetration testing and follow CMMI Level 5 and ISO 27001 certified processes to mitigate risks and protect your assets and users.
The best platform depends on your project's goals regarding scalability, transaction costs, security, and community. Ethereum is the most established for dApps and DeFi. Solana offers high speed and low costs. Polygon is a leading Layer-2 scaling solution for Ethereum. We provide expert consultation to help you select the optimal blockchain for your specific use case.
A Minimum Viable Product (MVP) for a dApp can typically be developed in 3 to 6 months. A more complex application with advanced features and integrations can take 6 to 12 months or longer. Our AI-accelerated development process and agile methodology help us deliver high-quality products faster than traditional development cycles.
Absolutely. Upon final payment, we transfer 100% of the intellectual property and source code to you. Our engagement is structured to ensure you have full ownership and control over your project.
