Web3 Development for Business

Services

Web3 solutions that drive your business

We build decentralized applications, blockchain games, wallets and DeFi protocols tailored to each client's specific needs. From concept to mainnet deployment.

01

dApp Development

We create complete decentralized applications: from smart contract logic to frontend with Web3 wallet integration. Intuitive interfaces on secure protocols across Ethereum, Polygon, BNB Chain, Solana and more.

Frequently asked questions about Web3 Development

We answer the most common questions about our Web3 development services.

Web3 development involves creating applications and services that run on decentralized blockchain networks. Unlike the traditional web (Web2), Web3 applications offer true digital ownership, transparency, censorship resistance and eliminate intermediaries through smart contracts.

We develop the full spectrum of Web3 solutions: decentralized applications (dApps), blockchain games and GameFi, custom wallets, DeFi protocols (DEX, lending, staking), NFT marketplaces, DAOs with on-chain governance, decentralized identity systems and cross-chain bridges.

We work with major networks: Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Base, Solana, Avalanche, Tron and other EVM-compatible networks. Network selection depends on project type, transaction costs and performance requirements.

Costs vary by complexity. A basic dApp can start from a few thousand euros, while a full blockchain game or DeFi protocol may require a larger investment. We offer free consulting to evaluate your project and provide a custom quote.

We follow security best practices at every stage: smart contract auditing, vulnerability analysis, thorough testnet testing, use of audited libraries like OpenZeppelin and peer code review. Our zero-hack track record validates our methodology.

Yes. We can add Web3 functionality to your current platform without rebuilding it: wallet authentication (Sign-In with Ethereum), cryptocurrency payments, NFT verification, decentralized storage and more. Integration is gradual and does not affect your current operations.

Account Abstraction (ERC-4337) enables smart wallets that remove Web3 entry barriers: gasless transactions where the business pays fees, account recovery without seed phrases, and authentication via email or biometrics. It is key to mass adoption of Web3 applications.
