Frequently Asked Questions

FAQs

Find answers to your common concerns

Can you handle projects for any industry?

Yes, we have experience working with clients across various industries including healthcare, finance, education, retail, and more. We tailor our solutions to meet the unique challenges and compliance requirements of each sector.

What blockchain platforms do you work with?

We specialize in several leading blockchain platforms including Ethereum, Hyperledger Fabric, Binance Smart Chain, Cardano, Solana, and Polygon. These platforms support a wide range of applications, from smart contracts to decentralized apps (DApps), tailored to meet diverse project needs.

What is your project management style?

We use Agile methodologies to manage projects, ensuring flexibility and collaboration. Regular updates and iterations are part of our process, allowing us to adapt quickly and efficiently to any changes or feedback.

How do you price your services?

Our pricing is based on the project scope, technology stack, and resource requirements. We offer both fixed-price contracts and time-and-materials pricing models. A detailed quote is provided after the initial consultation and project scope definition.

How long does it take to build a blockchain solution?

Timeline depends on complexity — a basic smart contract or dApp MVP can take 4-8 weeks, while a full DeFi platform, NFT marketplace, or DAO infrastructure typically takes 3-6 months from discovery to production deployment.

How much does smart contract development cost?

Costs vary based on contract complexity, audit requirements, and blockchain network. Simple smart contracts start in the low thousands, while complex DeFi protocols or multi-contract systems with full security audits require a larger budget. We provide a detailed quote after scoping your use case.

Do you audit smart contracts before deployment?

Yes. Every smart contract we build goes through a dedicated security audit phase to identify vulnerabilities, logic errors, and gas inefficiencies before mainnet deployment. We also audit third-party or existing contracts on request.

Is blockchain the right solution for my business?

Blockchain adds the most value when you need transparency, immutability, decentralized trust between parties, or tokenized assets — common in FinTech, supply chain, healthcare records, and digital ownership use cases. We help assess fit during a free discovery call before committing to development.

Can you integrate blockchain with our existing systems?

Yes. We connect blockchain solutions with existing CRMs, ERPs, payment gateways, and internal databases, so smart contracts and on-chain data work alongside your current infrastructure rather than replacing it.

Do you build on public or private blockchains?

Both. We work with public networks like Ethereum, Solana, and Polygon for open, permissionless use cases, and permissioned frameworks like Hyperledger Fabric for enterprise, government, and consortium projects that require controlled access.

What ongoing support do you provide after launch?

We offer post-launch monitoring, smart contract upgrades, gas optimization, and security patching, plus support for scaling your solution as transaction volume or user base grows.

How do you handle regulatory compliance for blockchain projects?

We design solutions with KYC/AML, data privacy, and jurisdiction-specific regulatory requirements in mind from the architecture stage, and can advise on compliance considerations for FinTech, banking, and government use cases.
