When you brief a dApp development company in India, four early decisions shape everything else: which chain you deploy on, how users connect a wallet, who pays for gas and how the contracts will be audited. Settle these in the scoping phase and your team avoids expensive rewrites, stalled launches and users who give up at the first signature prompt.
Decision one: which chain fits your dApp
Chain choice is a product decision disguised as a technical one. It fixes your transaction fees, confirmation times, available tooling and where your users already hold assets.
Ethereum and its Layer 2 networks
Ethereum mainnet has the deepest liquidity, security and developer tooling, but fees make frequent small interactions painful. Rollups such as Arbitrum, Optimism and Base inherit much of Ethereum's security with far lower fees, and most Solidity code runs on them unchanged. For many consumer dApps, a Layer 2 is the sensible default; our note on Layer 2 blockchain integration covers bridging and finality in more detail.
Solana and other non-EVM chains
Solana offers high throughput and low fees with programs written in Rust. It suits high-frequency interactions such as games or order-book trading, but requires a different skill set, different wallets and different audit firms.
Permissioned or app-specific chains
Enterprises sometimes need private data and known validators. In that case ask honestly whether a shared public chain is needed at all, or whether a permissioned ledger is a better fit.
Not sure which way to go? Describe your users and transaction patterns to us and we will recommend a chain with the reasoning written down.
Decision two: wallet UX that does not lose users
Most people who abandon a dApp do it at the wallet step. Seed phrases, network switching and cryptic signature requests are real barriers for mainstream audiences.
- External wallets via WalletConnect or browser extensions suit crypto-native users who already own assets.
- Embedded wallets let users sign in with email or social login while keys are secured by MPC or secure enclaves, which feels like a normal app.
- Smart accounts built on ERC-4337 account abstraction enable session keys, batched actions, spending limits and social recovery.
Whatever you choose, show human-readable signing requests using EIP-712 typed data, simulate transactions before asking users to sign and explain every prompt in plain language. Offer both paths if your audience is mixed.
Decision three: gas strategy
Gas is both a cost and a UX problem. A thoughtful strategy reduces what users pay and how often they are asked to pay it.
Optimising contract costs
Storage writes are the most expensive operation on EVM chains. Packing variables, emitting events instead of storing history, avoiding unbounded loops and using batch operations all lower fees. Keep business logic on-chain only when it needs trustless enforcement; everything else can live in your backend.
Sponsoring gas for users
Paymasters in the ERC-4337 model let your application pay fees on the user's behalf, or accept payment in a stablecoin. This is powerful for onboarding, but you need abuse limits so bots cannot drain your sponsorship budget.
When sponsorship makes sense
It works well for first actions, low-value frequent interactions and enterprise users who should never see a gas prompt. For high-value trades, users usually expect to pay their own fees.
Decision four: audits and security planning
Deployed contracts are public, immutable targets. Plan security from the scoping stage rather than bolting on an audit the week before launch.
- Freeze the contract scope before the audit; changes afterwards need re-review.
- Write unit, fuzz and invariant tests with Foundry or Hardhat; auditors review better when tests are thorough.
- Use battle-tested libraries such as OpenZeppelin rather than writing token or access-control logic from scratch.
- Budget time for fixing findings and a re-check.
- After launch, add monitoring, an incident plan and consider a bug bounty.

What a dApp development company in India should handle beyond contracts
Contracts are often a minority of the code. A working product also needs an indexer (such as The Graph or a custom service) so the front end can query history quickly, a backend for off-chain data and notifications, RPC infrastructure with failover and an admin view for operations. Scope these explicitly, or they will surface as surprises mid-project.
Also decide early how you will handle chain reorganisations, RPC outages and pending transactions in the interface. Users should always see whether an action is submitted, confirmed or failed, with a link to the block explorer. Small details like these separate a prototype from a product people trust with their assets.
Working with iJurug Soft on a dApp
iJurug Soft has been building software from Bangalore since 2018, and blockchain development is one of the services we offer alongside web and mobile apps. That combination matters for dApps, because the React or Flutter interface is where users judge you. Every engagement has senior engineers and fixed milestones: Discover, Design, Build, then Launch and grow with long-term support. Effort depends on chain count, contract complexity, wallet approach, indexing needs and audit scope, so we quote each project after discovery rather than listing prices.
Frequently asked questions
How long does a dApp take to build?
It depends on contract complexity and front-end scope. A focused MVP with a small contract set moves much faster than a multi-chain protocol; discovery gives you a realistic timeline.
Can we support several chains?
Yes, but each chain adds deployment, testing and monitoring overhead. Launch on one, prove demand, then expand.
Should contracts be upgradeable?
Upgradeability helps fix bugs but adds trust assumptions. Many teams use proxies governed by a multisig with a timelock.
What should we prepare before the first call?
A short description of the problem, who your users are, whether they already hold crypto, any chain or token commitments and your launch window. Rough wireframes help but are not required.
