What Our Clients Say
Frequently Asked Questions
Web3 represents the next evolution of the internet, built on decentralized technologies like blockchain. It shifts power from large corporations to individual users, enabling concepts like true data ownership, transparent transactions, and community-governed platforms. For businesses, it unlocks opportunities for new models in finance (DeFi), digital assets (NFTs), and user engagement, fostering greater trust and reducing reliance on intermediaries.
The cost varies significantly based on complexity. A simple proof-of-concept or MVP might start around $50,000. A full-featured dApp, NFT marketplace, or DeFi platform can range from $100,000 to over $500,000. Key factors include the choice of blockchain, complexity of smart contracts, security audit requirements, and UI/UX design. We provide a detailed, transparent quote after our initial discovery phase.
Security is our highest priority. Our multi-layered approach includes: 1) Adhering to secure coding best practices from day one. 2) Conducting rigorous internal code reviews. 3) Implementing comprehensive unit and integration testing. 4) Using industry-standard tools for static and dynamic analysis. 5) Engaging reputable third-party firms for external security audits before mainnet deployment. We believe in a "never trust, always verify" mindset.
The best platform depends on your specific needs. Ethereum is the most established with the largest ecosystem, ideal for projects prioritizing security and decentralization. Solana offers high throughput and low transaction fees, making it great for gaming and high-volume applications. Polygon provides a scalable Layer 2 solution for Ethereum-based projects. We'll help you analyze the trade-offs and select the optimal blockchain for your goals.
A typical Web3 project follows several phases. A Proof of Concept (PoC) can take 4-6 weeks. A Minimum Viable Product (MVP) usually takes 3-5 months. A full-scale, production-ready application can take 6-12 months or more, depending on its complexity. Our agile process involves regular sprints and transparent communication, so you are always aware of the progress and upcoming milestones.
