Crypto Exchange Development in Mumbai

Crypto exchange development for venues that hold custody and stay up

An exchange is a payments business, a custody business and a low latency trading system at the same time, and it is judged on the worst of the three. e10 Infotech Private Limited builds trading venues with the parts most teams underestimate: a matching engine that is deterministic under load, a risk engine that stops a bad fill becoming a bad day, custody with real key separation, and an operations console your compliance team can actually run. Businesses in Mumbai come to us when a venue has to handle client funds, not just quote prices.

What we build

1. Centralised spot exchanges with a deterministic matching engine and full order lifecycle
2. Derivatives venues with margin, funding, mark price and forced liquidation
3. Over the counter and request for quote desks with negotiated settlement
4. Brokerage and swap products routing to external liquidity
5. Hybrid venues settling on chain while matching off chain
6. Hot, warm and cold custody with policy driven withdrawal approval
7. Compliance operations for client onboarding, sanctions screening, transaction surveillance and regulatory reporting

How the build runs

The matching engine is built first and in isolation, single threaded per market with an append only journal, so every state can be replayed and reconciled exactly. Order types, self trade prevention, tick and lot sizing and cancel semantics are specified before code because they define fairness. The risk engine sits in front of matching, checking balance, margin and rate limits on every order rather than after the fact. Custody separates hot float from cold reserve with withdrawal policy enforced by quorum, address allowlists and velocity limits. Ledgering is double entry throughout, with an internal proof that assets held always cover client balances. Load testing runs at multiples of expected peak, including cancel storms and a market moving twenty percent in a minute.

Where this fits

Exchange work sits inside our Web3 Development practice. Settlement contracts and on-chain components come from Smart Contract Development, node and network infrastructure from Blockchain Development, and listed assets from Token Development or RWA Tokenization where instruments are regulated. On-chain liquidity and hybrid routing draw on DeFi Development, user custody on Crypto Wallet Development, collectible markets on NFT Marketplace Development, and community owned venues on DAO Development. The trading interface and marketing site are built by Web Development, with back office systems from Software Development.

Custody, keys and treasury

Client assets are segregated from operational funds in the ledger and in the wallets. Cold storage uses hardware security modules or multi party computation with a documented signer set, quorum thresholds and a rehearsed recovery ceremony. Hot wallet float is capped and refilled on policy rather than on request. Every withdrawal passes address screening, allowlist checks and velocity limits, and anything above threshold needs human approval from a second role. Reconciliation between chain balances, wallet balances and the internal ledger runs continuously with alerts on any drift.

Compliance operations

Onboarding supports tiered verification with document checks, liveness and sanctions screening, refreshed on a schedule rather than once. Transaction monitoring flags structuring, rapid pass through and exposure to sanctioned or high risk addresses using chain analytics. Travel rule messaging, suspicious activity reporting and audit exports are built in rather than bolted on, and every privileged action in the admin console is logged against a named operator.

What you get at handover

Source code in your repositories, infrastructure as code in your cloud accounts, the matching engine specification and replay tooling, custody policy and key ceremony records, reconciliation and proof of reserves reporting, compliance runbooks, load test results at documented throughput, monitoring with on call routing, and a thirty day warranty on behaviour that does not match the specification.

Working with businesses in Mumbai

Work for clients in Mumbai runs remote first: a named engineering team, a scope agreed in writing before anything starts, and demos on a fixed cadence you can hold us to. Working hours overlap your business day and everything is delivered in English.

Operating a trading venue is a licensed activity in most places, and the requirements differ sharply by jurisdiction, so we confirm what applies to businesses in Mumbai with your counsel and compliance advisers before the platform is scoped. That answer shapes the build rather than following it.

You get one point of contact, senior engineers on delivery, and reporting tied to running, reconciled software rather than activity. Businesses in Mumbai and the wider region are supported on the same terms.
