Our Blockchain Development Process
Security and correctness are non-negotiable in blockchain. Our process puts architecture and testing before deployment.
Blockchain Architecture Review
We map your business logic to on-chain and off-chain components. Chain selection, token standard, and security model defined upfront.
Smart Contract Design
We draft contract interfaces, state machine diagrams, and security threat models before writing a line of Solidity.
Contract Development & Testing
Solidity contracts built with Foundry. 100% branch coverage tests. Fuzzing for edge cases. Gas optimization pass.
Testnet Deployment
Deployed on testnet for functional review. You can interact with the contracts and verify behavior.
Web3 Frontend Integration
Next.js + wagmi frontend connecting to deployed contracts. Wallet flows, transaction state, error handling.
Mainnet Deployment & Monitoring
Mainnet deployment with verified contract source on Etherscan. Event monitoring and alerting setup.
Frequently Asked Questions
Which blockchains does Xenotix Labs develop on?
We primarily develop on Ethereum (mainnet and testnets), Polygon, Binance Smart Chain (BSC), Arbitrum, Optimism, and Base. For enterprise use cases, we also work with Hyperledger Fabric and private EVM-compatible chains. We recommend the right chain based on your gas cost, transaction speed, and audience requirements.
How much does blockchain development cost in India?
Smart contract development for a single protocol costs ₹2–6 Lakhs ($2,500–$7,500 USD). A full DeFi or NFT platform with a Web3 frontend and admin dashboard costs ₹8–20 Lakhs ($10,000–$24,000 USD). Enterprise blockchain platforms with custom consensus, multi-chain support, and compliance layers start at ₹20 Lakhs ($24,000 USD). Timelines are 4–12 weeks depending on complexity.
Do you audit smart contracts for security?
We follow secure-by-default practices using Foundry for testing, OpenZeppelin libraries for battle-tested contract patterns, and static analysis with Slither. For production deployments handling significant TVL, we recommend an independent audit from a specialist firm (Certik, Trail of Bits, OpenZeppelin). We can coordinate and prepare your codebase for external audits as part of our delivery.
Can you build an NFT marketplace?
Yes. We build full NFT marketplaces including ERC-721/ERC-1155 smart contracts, lazy minting, royalty enforcement (EIP-2981), IPFS/Arweave metadata storage, wallet connection (MetaMask, WalletConnect), and a Next.js frontend. A basic NFT marketplace takes 6–8 weeks. A full-featured platform with auctions, bundling, and offers takes 10–12 weeks.
What tools and frameworks do you use for blockchain development?
We use Solidity for EVM smart contracts and Foundry as our development and testing framework. For Web3 frontend integration, we use ethers.js and wagmi with React or Next.js. For IPFS storage, we use Pinata or NFT.Storage. We use Hardhat for legacy projects and OpenZeppelin contracts for security-critical logic.
