Blockchain Development Company
Smart contracts, DApps, and decentralized systems
We build blockchain applications for companies that need trustless transactions, immutable records, and decentralized logic. Our team has delivered 15+ blockchain projects — from ERC-20 token systems managing $10M+ in assets to supply chain tracking platforms recording 1M+ transactions to NFT marketplaces with 50K+ minted assets. Every smart contract goes through formal security auditing before mainnet deployment. Need dedicated talent? Hire blockchain developers from our pre-vetted team. For full DApp delivery, explore our custom software development services.
What sets our blockchain development apart
Audited Smart Contracts
We write Solidity smart contracts with formal verification, unit testing with Foundry, and third-party security audits. Gas optimization reduces transaction costs by 30-50%.
Multi-Chain Development
Ethereum, Polygon, Arbitrum, Base, Solana, and private Hyperledger networks. We select the chain based on your transaction volume, cost requirements, and decentralization needs.
DApp Frontend Integration
Web3 frontends with wagmi, viem, and WalletConnect. Wallet connection, transaction signing, on-chain data display, and real-time event listening with user-friendly interfaces.
Tokenomics & Token Systems
ERC-20, ERC-721, and ERC-1155 token design. Vesting schedules, staking mechanisms, governance contracts, and economic modeling for sustainable token ecosystems.
Private Blockchain Solutions
Hyperledger Fabric and Besu for enterprise consortiums. Permissioned networks for supply chain, healthcare records, and financial settlements where public chains are not appropriate.

Common questions about blockchain development
Does my project actually need blockchain?
Not always. Blockchain adds value when you need trustless transactions between multiple parties, immutable audit trails, or programmable assets (tokens/NFTs). If a central database with proper access controls solves your problem, we will tell you that. We run a needs assessment before recommending blockchain.
How much does smart contract development cost?
A standard ERC-20 token with basic functionality costs $5,000-$15,000 including audit. A full DApp with smart contracts, frontend, and backend runs $30,000-$80,000. Complex DeFi protocols with multiple interacting contracts range from $80,000-$250,000. Security auditing adds 15-25% to the total.
How do you ensure smart contract security?
We follow a four-layer process: static analysis with Slither, unit testing with 100% branch coverage using Foundry, internal peer review, and third-party audit by firms like OpenZeppelin or Trail of Bits. We also implement timelocks and multi-sig on admin functions.
Which blockchain should I build on?
Ethereum for maximum decentralization and liquidity. Polygon or Arbitrum for lower gas fees with Ethereum security. Solana for high-throughput consumer apps. Hyperledger for private enterprise networks. We evaluate based on your transaction volume, cost sensitivity, and target user base.
Can you build both the smart contracts and the web app?
Yes. We deliver end-to-end blockchain projects: smart contract development and audit, subgraph indexing with The Graph, React/Next.js frontend with wallet integration, and Node.js backend for off-chain logic. One team, one codebase, coherent architecture.
How much does it cost to hire a dedicated blockchain developer?
Dedicated blockchain developers cost $3,000-$4,500/month for junior, $4,500-$7,000/month for mid-level, and $7,000-$10,000/month for senior Solidity engineers. Auditing specialists command an additional premium. Full-time, 160 hours/month. US blockchain developers cost $15,000-$25,000/month.
How long does a smart contract audit take and what does it cost?
A basic ERC-20 audit takes 1-2 weeks and costs $5,000-$10,000. A complex DeFi protocol audit takes 3-6 weeks and costs $15,000-$50,000 depending on lines of code and contract interactions. We perform internal audits first, then coordinate with third-party firms like OpenZeppelin for the final review.
Can you build a custom NFT marketplace for my brand?
Yes. We have built 15+ blockchain projects including NFT marketplaces with 50K+ minted assets. A custom NFT marketplace with minting, listings, royalties, and wallet integration costs $30,000-$80,000 and takes 12-20 weeks. Get a dedicated blockchain developer from $4,500/month to start building in 1 week.
