Frequently Asked Questions

  • What is the difference between custom blockchain development and using an existing platform like Ethereum or Polygon?

    Custom blockchain development (often called building a Layer 1 or Private DLT) involves creating a network from the ground up, giving you total control over consensus mechanisms, transaction fees (gas), and governance. Using an existing platform (like Ethereum or Polygon) means developing a dApp or Layer 2 solution on top of its established rules, offering speed and access to its existing user base, but less control over core architecture.

  • How long does it take to develop a custom blockchain solution or a complex dApp?

    The timeline varies widely based on complexity. A basic Smart Contract or simple Token deployment might take 4-8 weeks. A complex project, such as a full Decentralized Exchange (DEX), a custom Layer 1 chain, or an enterprise-grade supply chain solution, typically requires 4 to 9 months or longer, including the crucial phases of architecture design, development, and rigorous security auditing.

  • What types of Smart Contract security audits do you perform, and why are they necessary?

    We perform comprehensive audits to identify potential vulnerabilities, including reentrancy attacks, gas limit issues, overflow/underflow errors, and logic flaws. Audits are necessary because smart contracts are immutable (cannot be changed after deployment), meaning any bug could result in catastrophic financial loss or permanent system failure. Our audits provide an essential layer of security and trust.

  • Which blockchain platforms (protocols) does your team specialize in developing for?

    Our expertise spans major ecosystems, including Ethereum (EVM-compatible chains like Polygon, BSC, Avalanche), Solana, and enterprise solutions like Hyperledger Fabric and Corda. We select the optimal platform based on your project's specific requirements for scalability, consensus type, transaction speed, and regulatory needs.

  • What is the process for engaging Web3Twenty to start a new blockchain project?

    The process begins with a Discovery & Consultation phase to define the project scope, technical requirements, and business goals. This is followed by Architecture Design, Development Sprints, rigorous Security Auditing, Deployment, and ongoing Maintenance/Support. We work closely with your team through every milestone to ensure alignment and success.
