Frequently Asked Questions
Common questions about hiring developers
What blockchain platforms do your developers work with?
Our developers are experienced with Ethereum, Polygon, Solana, BNB Chain, Arbitrum, Optimism, Avalanche, and other EVM-compatible chains. They help you select the right chain based on your requirements for speed, cost, security, and ecosystem.
How do your developers ensure smart contract security?
Our developers follow security best practices including comprehensive unit and integration testing, use of audited libraries like OpenZeppelin, formal verification where applicable, gas optimization, and preparation for third-party security audits.
Can your developers build DeFi protocols?
Yes. Our blockchain developers have experience building DEXs, lending platforms, yield farming protocols, staking mechanisms, and governance systems. They understand the financial and security implications of DeFi smart contract development.
Do your developers handle the frontend DApp as well?
Yes. Our blockchain developers build complete Web3 applications including React-based frontends with wallet integration (MetaMask, WalletConnect), transaction management, and real-time blockchain data using The Graph or direct RPC calls.
Can they help with tokenomics and token development?
Our developers implement token contracts (ERC-20, ERC-721, ERC-1155) with custom features like vesting schedules, governance voting, and staking. For tokenomics design, we recommend working with a tokenomics advisor alongside our developers.
How quickly can a blockchain developer start?
We can have a blockchain developer onboarded and reviewing your architecture within 48 hours. Smart contract development typically begins in the first week after understanding requirements.
