Blockchain development company in India for smart contracts, DApps, and crypto products

Xenotix Labs is a blockchain development company in India that ships smart contracts, decentralized applications, and crypto-integrated products. Our flagship blockchain engagement is BullBot — a crypto-rails MLM platform where smart contracts handle commission payouts and on-chain audits. We have also delivered crypto-wallet integrations and Web3 auth flows across multiple consumer products.

We are deliberately careful in this space. Blockchain is the right answer for a narrow set of problems — programmable money, immutable provenance, trust-minimized coordination — and the wrong answer for everything else. Most "blockchain" features founders ask for are better served by a Postgres table with audit logs. When that is true, we will tell you. When it is not, we have shipped real on-chain systems and we know where the sharp edges are (gas economics, MEV, oracle trust, key custody).

Our default chains are Ethereum and EVM-compatible L2s (Polygon, Arbitrum, Base) — most ecosystem, deepest tooling, easiest to staff. We work with Solana when use case warrants. We do not write our own L1.

Sub-services

What we ship inside blockchain development

Real engagements, real case studies — not a feature list. Each sub-service is one we have shipped to production.

Smart Contract Audit Coordination

We do not pretend to be an audit firm. We work with external auditors (Trail of Bits, OpenZeppelin, smaller specialists) and ship contracts post-audit only.

Use cases: Pre-mainnet, before any user funds touch a contract

Shipped on: Standard practice on every BullBot contract revision

Tech stack reasoning

Why Ethereum + L2 is our default, and when we say no to blockchain

Ethereum and EVM-compatible L2s (Polygon, Arbitrum, Base) are our default because the tooling depth, auditor availability, and engineering talent pool are an order of magnitude ahead of any other chain. For most use cases — stablecoin payouts, NFTs, on-chain coordination, simple DeFi — an EVM L2 is the right choice on cost, on speed, and on "can we hire for this in two years".

We say no to blockchain more often than we say yes. Examples of "blockchain" features we have talked founders out of: a "blockchain database" for medical records (Postgres with audit logs solves this); a "decentralized social network" (federated is better unless censorship-resistance is the explicit goal); a "blockchain ticketing" system (a signed JWT on a vendor backend is cheaper and faster). We will lose the engagement saying no — and keep our integrity saying it. Founders we say no to often come back later for a non-blockchain build.

When blockchain is right (programmable payouts, immutable provenance, trust-minimized coordination), we ship: Solidity contracts with full test coverage, written threat model, external audit, on-chain monitoring (Tenderly / OpenZeppelin Defender), and gas-aware deployment. No code touches mainnet without an audit.

Pricing & timeline

How much does blockchain development services cost?

Published tiers, not opaque quotes. Every range below is one we have shipped engagements at.

Smart Contract Module

₹3,00,000 – ₹6,00,000

$4,000 – $7,500

Timeline3-5 weeks
Team1 Solidity engineer + 0.5 frontend
ScopeSingle-contract feature (token, NFT collection, simple payout) on EVM L2 with test coverage
Best forToken launches, NFT drops, simple payout logic

DApp MVP

₹8,00,000 – ₹18,00,000

$10,000 – $22,000

Timeline8-12 weeks
Team1 Solidity, 1 frontend, 1 backend, 0.5 designer
ScopeFull Web3 product — frontend, smart contract, wallet connect, basic admin. Pre-audit.
Best forCrypto MVPs, internal DAOs, Web3 product validation

Production DApp / Marketplace

₹20,00,000 – ₹50,00,000+

$25,000 – $60,000+

Timeline4-7 months
Team2 Solidity, 2 frontend, 1 backend, 1 designer

Best forNFT marketplaces, lending protocols, user-funds-handling DApps

Pricing varies with scope, integrations, and compliance needs. Every engagement starts with a fixed-scope written estimate after a 2-week paid discovery — never an open hourly meter.

Why founders pick Xenotix

Why Xenotix Labs for blockchain development

We say no to blockchain more than we say yes

If a Postgres table solves your problem, we will tell you. Our reputation is worth more than one engagement.

No mainnet code without an audit

We work with external auditors and refuse to deploy unaudited code touching user funds.

Threat model in writing before code

Every smart-contract engagement starts with a written threat model — attack vectors, gas griefing, MEV exposure, oracle trust.

EVM-first

Polygon, Arbitrum, Base, Ethereum mainnet. Deepest tooling, deepest audit market, deepest hireable talent pool.

Live on-chain product

BullBot is in production with smart-contract-driven commissions. Not a deck.

Common Questions

Frequently Asked Questions

Everything you need to know about blockchain development services

Do I actually need blockchain for my product?

Probably not. Blockchain is the right answer for programmable payouts, immutable provenance, and trust-minimized coordination. For most other use cases, a Postgres table with audit logs is cheaper, faster, and easier to maintain. We will tell you on the first call.

Which blockchain should I build on?

For most use cases, an EVM L2 (Polygon, Arbitrum, Base). Deepest tooling, deepest auditor market, easiest to hire for. We use Solana when use case warrants. We do not recommend writing your own L1.

How much does smart contract development cost?

Single-contract feature: ₹3-6 lakh. DApp MVP: ₹8-18 lakh. Production DApp / marketplace: ₹20-50 lakh+. External audit is additional and quoted separately.

Do you do smart contract audits?

No, and you should be skeptical of any agency that does both build and audit on the same contract. We coordinate with external audit firms (Trail of Bits, OpenZeppelin, smaller specialists) and ship to mainnet only after audit pass.

Can you build an NFT marketplace?

Yes — full-stack with custom contracts, royalty distribution, on-chain provenance, and a Next.js front-end. Audit before mainnet is non-negotiable for us.

How do you handle gas economics?

Threat model includes gas griefing analysis. We deploy on L2 by default for gas reasons. Critical-path contracts get gas-snapshot tests in CI.

Do you do tokenomics?

We do tokenomics review before launch — vesting schedules, distribution, liquidity provisioning. Token economics is a domain that overlaps with finance and is best done with the founders, not for them.
