Web3 Development in Mumbai
e10 Infotech is a Web3 development company in Mumbai building blockchain, RWA tokenization, smart contract, DeFi, NFT and crypto wallet products.
A Web3 development company that ships audited, working products
e10 Infotech Private Limited builds Web3 products that survive contact with real users and real money. Every engagement opens with the same question: what genuinely needs to sit on a blockchain, and what is cheaper, faster and safer kept off it. That single decision drives the network choice, the contract architecture, the custody model, the indexing layer and the compliance surface, so what you launch is defensible rather than merely expensive. Businesses in Mumbai come to us when a token, a marketplace or a tokenized asset has to reach production.
What we build
- Tokenized real world assets with transfer rules, registries and investor onboarding
- Layer 1 and layer 2 protocol work, application chains, rollups and bridges
- Smart contracts in Solidity and Rust, written to be audited and then audited
- Exchanges, order books, liquidity routing and settlement infrastructure
- Fungible tokens with vesting, staking and treasury tooling
- NFT collections, marketplaces, royalty enforcement and dynamic metadata
- Custodial and non custodial wallets, account abstraction and passkey signing
- DeFi primitives including lending markets, yield vaults and automated market makers
How a Web3 build runs
Discovery fixes the token model, the actors and the money flows before a line of Solidity exists. Architecture then splits the system into on-chain state, off-chain compute and indexed reads, because gas is a design constraint rather than an afterthought. Contracts are written test first with full branch coverage, fuzzed against stated invariants, deployed to a public testnet and put through an independent audit. Front ends are built against the same ABI the contracts expose, indexers backfill history, and monitoring watches failed transactions, stuck nonces and unusual approvals on day one. Upgrade paths, pause switches and key rotation are specified before mainnet, not improvised during an incident.
Where the pieces fit
Most Web3 projects combine several of these services. Blockchain Development sets the network and the infrastructure, Smart Contract Development writes and audits the on-chain logic, and RWA Tokenization handles regulated assets that need transfer restrictions. Issuance normally runs through Token Development, trading through Crypto Exchange Development and DeFi Development, while collectibles and digital rights sit with NFT Marketplace Development. Users reach all of it through Crypto Wallet Development, and community owned projects add DAO Development. Conventional front ends come from Web Development, and model driven features from AI First Development.
Networks and tooling
We work on Ethereum and the EVM layer twos including Arbitrum, Optimism, Base and Polygon, plus Solana, Avalanche subnets, Cosmos SDK chains and permissioned Hyperledger Fabric networks. Daily tooling is Foundry and Hardhat, OpenZeppelin libraries, Slither and Echidna for analysis, The Graph and custom indexers for reads, IPFS and Arweave for storage, Chainlink and Pyth for price data, and Safe for multisig treasuries.
Security, custody and compliance
Private keys are the product. We separate deployer, admin and treasury roles, put timelocks in front of privileged functions, and default to multisig control with documented signer recovery. Where an asset is regulated we implement allowlists, transfer agents and jurisdiction rules in the contract itself, and keep KYC and sanctions screening off-chain behind a permissioned service. Audit reports, test coverage and threat models are handed over with the code so your next reviewer starts informed.
What you get at handover
Verified contract source published on the block explorer, deployment scripts and addresses for every network, the audit report with remediations closed, subgraphs and indexer configuration, a signer and key custody runbook, monitoring dashboards with alerting, 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.
Regulatory treatment of tokens and digital assets differs by jurisdiction, so we check what applies to businesses in Mumbai before scoping issuance, custody or trading features. That research shapes the build rather than following it.
You get one point of contact, senior engineers on delivery, and reporting tied to shipped contracts and working software rather than activity. Businesses in Mumbai and the wider region are supported on the same terms.

Queries raised before signature
Everything worth knowing about Web3 Development in Mumbai.
01What is Web3 development?
Web3 development is building applications where some state, ownership or settlement lives on a blockchain instead of only in a private database. In practice it combines smart contracts, wallets, indexers and a conventional front end.
02How much does a Web3 project cost?
A single audited token contract with a claim page is the smallest useful piece of work. Marketplaces, exchanges and tokenization platforms cost considerably more because of integrations, audits and compliance. We quote a fixed scope after discovery.
03Which blockchain should we build on?
It depends on who holds your users, what a transaction may cost them and whether you need permissioned access. Ethereum layer twos suit consumer volume, Solana suits high throughput trading, and Hyperledger Fabric suits closed consortium networks.
04Do you audit smart contracts?
Yes. We run static analysis, fuzzing and invariant testing in house, and we coordinate an independent third party audit before mainnet. Findings are fixed and retested before deployment.
05Can you tokenize real world assets?
Yes. Real estate, private credit, funds, commodities and invoices are all workable. The contract enforces transfer restrictions while the legal wrapper, custody and investor onboarding sit alongside it.
06How long does a Web3 build take?
A token launch with vesting and a claim interface usually takes four to six weeks including audit. A marketplace or exchange runs three to six months depending on integrations and licensing.
07Do you handle regulatory and legal work?
We build to the rules your counsel sets and implement them in code, including allowlists, lockups and jurisdiction blocks. We do not give legal advice and we work directly with your lawyers.
08Can you take over an existing Web3 codebase?
Yes. We start with a code review and threat model, document what the contracts actually do against what they were meant to do, then agree a remediation and roadmap before changing anything.
09What about gas costs and scalability?
Gas is treated as a budget from the first architecture session. We minimise on-chain writes, batch operations, use events and indexers for reads, and deploy to layer twos where fees would otherwise block adoption.
10Who owns the code and the keys?
You do. Repositories are in your organisation, deployments go from your accounts, and admin keys are generated and held by your signers. We never retain production key material.
11Do you build the front end as well?
Yes. Wallet connection, transaction states, gas estimation, error recovery and mobile behaviour are part of the build, because most Web3 products fail on interface rather than on contracts.
12What happens after launch?
You can take it in house or keep us on a support plan covering monitoring, incident response, contract upgrades, indexer maintenance, dependency patching and periodic security review.
13Do you offer Web3 Development in Mumbai?
Yes. e10 Infotech delivers Web3 Development for businesses in Mumbai and the wider region, remote first with a named team and a scope agreed before work starts.
14How do you run Web3 Development projects for clients in Mumbai?
Working hours overlap the Mumbai business day, communication is in English, and you get one point of contact with reporting tied to audited, deployed software rather than activity.
