DApp Development
End-to-end decentralised applications with seamless wallet integration and intuitive UX.
We build full-stack decentralised applications — smart contracts, indexing layer, and frontend — with wallet connection flows and on-chain UX that anyone can use.
DApps That Normal People Can Use
Most DApps are built for crypto natives, assuming MetaMask is installed and showing raw transaction hashes. We build DApps with the same UX rigour we apply to traditional web applications.
We handle progressive onboarding, human-readable error messages, gas estimation with clear cost previews, and transaction status tracking to guide users through the process step by step.
Our full-stack capability covers the entire DApp architecture: smart contracts, The Graph subgraphs for efficient indexing, and Next.js frontends with wagmi/viem for chain interactions.
Service Inclusions
Wallet Integration
RainbowKit or ConnectKit integration supporting MetaMask, WalletConnect v2, and 100+ wallets with mobile-first UX.
Subgraph Indexing
The Graph subgraph development for efficient on-chain data queries — replacing slow RPC calls.
Transaction UX
Pre-flight simulation, gas estimation in USD, transaction status tracking, and human-readable revert messages.
Web3 UI/UX Design
User research with non-crypto users, wallet onboarding flows, and conversion-optimised interfaces.
Mobile DApp
WalletConnect v2 mobile support, mobile-responsive design, and iOS/Android deep link handling.
On-Chain Notifications
Push Protocol or custom webhook systems for on-chain event notifications — keeping users informed.
A Process Built for Clarity
No black boxes. No surprise invoices. Every project at Codewingz follows a disciplined four-phase process designed to reduce risk and maximise value at every stage.
Architecture Design
Smart contract interface definition, subgraph schema design, and wallet connection strategy documented.
Smart Contract Integration
ABI integration, typed contract hooks, and comprehensive error handling for all revert scenarios.
Subgraph Development
The Graph subgraph mapping and schema for all required on-chain events.
Frontend Build
Next.js DApp with wallet connection, transaction flows, and real-time chain data display.
Testnet & User Testing
Full deployment to testnet, user testing with non-crypto participants, and iteration on friction points.
Mainnet Launch
Production deployment, monitoring setup, and analytics instrumentation.
The Tech Stack
We select technologies based on performance, scalability, and long-term maintainability, not trends.
Next.js / React
Specialized implementation of Next.js / React in the Frontend space.
wagmi / viem
Specialized implementation of wagmi / viem in the Chain Interaction space.
RainbowKit
Specialized implementation of RainbowKit in the Wallet UI space.
The Graph
Specialized implementation of The Graph in the Indexing space.
IPFS / Arweave
Specialized implementation of IPFS / Arweave in the Decentralised Storage space.
Real-World Impact
NFTBridge Protocol
The Challenge
“An NFT cross-chain bridge had a 67% drop-off before transaction confirmation — users did not understand what was happening.”
The Solution
We rebuilt the frontend with a guided 4-step flow, gas cost preview in USD, and live transaction status. The Graph subgraph reduced page load time significantly.
