What we build on blockchain

Smart Contract Development

Solidity contracts for tokens, escrow, staking, access control and custom business logic, written for clarity and tested before they go on-chain.

dApp Development

Decentralized applications with a polished web or mobile frontend, wallet connection and clear transaction flows that non-technical users can follow.

Web3 Integration

Add wallet login, on-chain payments or token-gated features to an existing website or app without rebuilding it.

Token & NFT Platforms

Token launches, NFT collections and marketplaces, including minting flows, metadata and admin tooling.

Consulting & Technical Review

A frank assessment of whether blockchain fits your idea, which network to use, and a review of existing contracts and architecture.

Why choose CohortIX for blockchain development in India

Frequently asked questions

Do I actually need blockchain for my project?

Not always. If you do not need decentralization, transparency between parties or on-chain ownership, a conventional system is often cheaper and simpler. We tell you honestly after a short call.

Which blockchains do you work with?

We build on Ethereum and EVM-compatible networks such as Polygon, and choose the network based on cost, speed and your users, not on trend.

Do you audit smart contracts?

We write tests and review our own contracts carefully. For contracts that hold significant value, we recommend an independent third-party security audit before launch.

How long does a blockchain project take?

A focused smart contract with a simple frontend can take a few weeks. Larger platforms are scoped and delivered in phases, with a clear plan up front.

Can you add Web3 features to my existing app?

Yes. We can add wallet login, token-gating or on-chain payments to an existing website or app without rebuilding it.
