DApp Development Company

A DApp (Decentralized Application) runs on blockchain networks instead of centralized servers. Key differences: Backend logic is in smart contracts (immutable and transparent), data is stored on blockchain/IPFS (censorship-resistant), users control their data via wallets, no single point of failure, and transactions are trustless. Regular apps use centralized databases and servers controlled by companies.

Costs vary by complexity: Basic DApp with simple features starts at ₹2,50,000 (8-10 weeks), Professional DApp with advanced features is ₹5,00,000 (12-16 weeks), Enterprise multi-chain DApp starts at ₹10,00,000+ (20-28 weeks). Factors affecting cost: number of smart contracts, blockchain platform, UI complexity, backend services, integrations, and security audit requirements.

We develop on all major platforms: Ethereum and L2s (Arbitrum, Optimism, zkSync) for maximum security and ecosystem, Binance Smart Chain for lower fees, Polygon for scalability, Solana for high-speed applications, Avalanche for custom subnets, and multi-chain solutions. Platform choice depends on transaction volume, gas costs, target audience, and specific features needed.

Yes, users need native tokens for gas fees (ETH on Ethereum, MATIC on Polygon, etc.). However, we implement solutions to improve UX: Meta-transactions (gasless transactions paid by app), Account abstraction (ERC-4337) for social logins, Fiat on-ramps for easy token purchase, and Gas station networks. We can also build hybrid models with off-chain features that don't require gas.

Multi-layer security: Smart contracts undergo rigorous audits (automated tools + manual review), frontend has input validation and XSS protection, wallet integration uses secure signing methods, backend APIs have authentication and rate limiting, IPFS content is verified via hashes, oracle data is from trusted sources (Chainlink), and we implement emergency pause mechanisms. All code is tested with 100% coverage.

DApps require internet for blockchain interaction, but we optimize for poor connections: Progressive Web Apps (PWA) for offline caching of UI, transaction queuing for when connection resumes, optimistic UI updates showing instant feedback, data caching via service workers, and lightweight payload design. Critical functions require stable connection, but browsing and preparation can work offline.

The Graph is a decentralized indexing protocol for blockchain data. Instead of scanning entire blockchain for events (slow and expensive), we create subgraphs that index specific contract data. Benefits: Fast data queries via GraphQL, real-time event tracking, historical data access, reduced API costs, and scalable architecture. Essential for DApps with complex data needs like marketplaces, analytics, or social platforms.

Scalability strategy includes: Layer 2 solutions (Arbitrum, Optimism) for reduced fees, sidechains (Polygon) for high throughput, backend caching layer (Redis) for frequent queries, CDN for static assets, database sharding for user data, load balancing across servers, auto-scaling infrastructure, and optimization of smart contract gas usage. We design for 10,000+ concurrent users from day one.
