Blockchain Development — Smart Contracts & Web3
We build smart contracts, dApps, and Web3 integrations on Ethereum and compatible chains. Secure, auditable, and production-ready blockchain solutions.
ZTABS provides blockchain development — We build smart contracts, dApps, and Web3 integrations on Ethereum and compatible chains. Secure, auditable, and production-ready blockchain solutions. Our capabilities include smart contract development, dapp development, token & nft solutions, and more.
How We Approach Blockchain Development
Blockchain technology enables trustless transactions, transparent record-keeping, and programmable assets — but building production-grade blockchain applications requires deep expertise in cryptography, gas optimization, and smart contract security. ZTABS develops blockchain solutions on Ethereum, Polygon, Solana, and EVM-compatible chains. We write smart contracts in Solidity and Rust, build decentralized applications (dApps) with React and ethers.js/wagmi, and integrate Web3 capabilities into existing web and mobile applications.
Our smart contract development follows security-first practices: formal verification, comprehensive unit testing with Hardhat and Foundry, and third-party audit preparation. We have built token contracts (ERC-20, ERC-721, ERC-1155), DeFi protocols (staking, liquidity pools, yield aggregators), NFT marketplaces, DAOs with on-chain governance, and supply chain tracking systems. For enterprises exploring blockchain, we offer proof-of-concept engagements that validate technical feasibility and business value before full development.
We also build hybrid architectures that combine on-chain settlement with off-chain computation for cost efficiency. Smart contract projects start at $20K for standard token or NFT contracts, while full dApp development ranges from $50K-$200K depending on protocol complexity and chain requirements.
Common Use Cases for Blockchain Development
- ERC-20, ERC-721, and ERC-1155 token creation and deployment
- NFT marketplace development with minting and trading features
- DeFi protocol development (staking, lending, yield farming)
- DAO governance and treasury management smart contracts
- Supply chain tracking and provenance verification
- Web3 wallet integration for existing web applications
- Cross-chain bridges and multi-chain deployment
- Tokenized real-world assets and fractional ownership platforms
