Blockchain & Web3 Development
Build decentralized applications, smart contracts, NFT marketplaces, and DeFi protocols on Ethereum, Solana, Polygon, and other leading blockchain platforms.
Decentralized Trust
Smart Contract Development
Smart contracts are self-executing programs on the blockchain that automatically enforce agreements without intermediaries. We write secure, gas-optimized Solidity contracts for Ethereum, Polygon, BSC, and EVM-compatible chains, plus Rust programs for Solana.
Every contract undergoes security audits, unit testing (Hardhat/Foundry), formal verification, and mainnet deployment with multi-sig wallets. We've deployed contracts handling millions in TVL with zero security incidents.
DApp & Web3 Integration
Decentralized applications (DApps) run on blockchain networks, offering transparency, censorship resistance, and user ownership. We build Web3 frontends with React/Next.js, connect to Web3 wallets (MetaMask, WalletConnect), and integrate smart contracts using ethers.js/web3.js.
Full-stack DApp development includes IPFS/Arweave for decentralized storage, The Graph for indexing blockchain data, and Layer 2 solutions (Arbitrum, Optimism) for scalability and reduced gas fees.
Web3 Experience
Blockchain Solutions We Build
From smart contracts to NFT marketplaces and DeFi protocols
Smart Contract Development & Audits
Write secure Solidity/Rust smart contracts for ERC-20/721/1155 tokens, multi-sig wallets, DAOs, staking, vesting, governance, and custom protocols. Gas optimization, reentrancy protection, overflow checks, and comprehensive testing with 100% code coverage.
NFT Marketplaces & Minting
Build NFT marketplaces with ERC-721/1155 minting, lazy minting, royalties (EIP-2981), auction systems, bidding, and IPFS/Arweave metadata storage. Support for generative art, PFP collections, and dynamic NFTs.
DeFi Protocols & DEXs
Decentralized exchanges, AMMs, yield farming, liquidity pools, and lending protocols
DAOs & Governance
Decentralized autonomous organizations with voting, proposals, and treasury management
Web3 Wallet Integration & Authentication
Connect DApps to MetaMask, WalletConnect, Coinbase Wallet, Phantom (Solana), and other Web3 wallets. Implement wallet-based authentication (Sign-In with Ethereum), transaction signing, gas estimation, and multi-chain support with network switching.
Layer 2 & Scalability
Deploy on Arbitrum, Optimism, Polygon zkEVM, StarkNet for lower gas fees
Blockchain Indexing & APIs
The Graph subgraphs, custom indexers, and GraphQL APIs for blockchain data

Smart Contract Development Process
From architecture to mainnet deployment in 6-12 weeks
Requirements & Architecture
1 week
Define tokenomics, contract logic, access controls, and gas optimization strategies. Design contract architecture with upgrade patterns (proxy/diamond) and security considerations.
Smart Contract Development
2-4 weeks
Write Solidity/Rust code following best practices (checks-effects-interactions, reentrancy guards). Implement ERC standards, custom logic, and modular contract design for reusability.
Testing & QA
1-2 weeks
Unit tests with Hardhat/Foundry achieving 100% code coverage. Integration tests, fuzzing, gas profiling, and testnet deployment (Goerli/Sepolia/Devnet) for real-world validation.
Security Audit
2-3 weeks
Third-party security audit by CertiK, OpenZeppelin, or Trail of Bits. Fix identified vulnerabilities, implement recommendations, and pass final audit before mainnet launch.
Frontend & Web3 Integration
2-3 weeks
Build React/Next.js DApp with wallet connection (MetaMask, WalletConnect), contract interaction using ethers.js, transaction handling, and event listening.
Mainnet Deployment & Monitoring
1 week
Deploy contracts to mainnet with multi-sig wallets, verify source code on Etherscan/Blockscout, set up monitoring (Tenderly/Defender), and prepare incident response plan.
