We build full-stack decentralized applications from smart contracts to polished frontends. Production-grade dApps with great UX, wallet integration, and multi-chain support.
A decentralized application is more than a smart contract with a frontend bolted on. It is an integrated system where on-chain logic, off-chain infrastructure, wallet connectivity, data indexing, and user experience work together seamlessly. Arthiq builds dApps as complete products — not disconnected layers assembled by different teams.
Our full-stack approach means a single team owns every layer. The engineers who write your smart contracts also build the indexing infrastructure and the frontend components that interact with those contracts. This vertical integration eliminates the communication gaps and integration bugs that plague projects where backend and frontend are developed independently.
We have built dApps for DeFi, NFTs, DAOs, gaming, social platforms, and enterprise applications. Each domain has its own UX patterns and technical requirements, and we bring domain-specific experience to every engagement. Our Product Owner mindset means we own the quality and delivery of the complete application, not just individual components.
The smart contract layer defines what your dApp can do on-chain. We develop in Solidity for EVM chains and Rust for Solana, using Hardhat, Foundry, and Anchor as our development frameworks. Every contract is built with security best practices, gas optimization, and upgradeability patterns appropriate for your use case.
We design contract architectures that separate concerns — core logic, access control, storage, and upgrade mechanisms each live in distinct modules. This modularity makes contracts easier to test, audit, and upgrade over time. For complex protocols, we use diamond or proxy patterns that allow individual facets to be upgraded independently.
Our testing methodology produces high-confidence contracts. We write unit tests for every function, integration tests for multi-contract interactions, fuzz tests for edge case discovery, and invariant tests that verify protocol properties hold under random operation sequences. Test coverage reports and deployment scripts are included in every delivery.
We build dApp frontends with Next.js, React, wagmi, and viem — the modern Web3 frontend stack that provides type-safe contract interaction, reactive state management, and support for all major wallet providers. Our frontends are responsive, accessible, and performant across desktop and mobile devices.
Wallet integration supports MetaMask, WalletConnect, Coinbase Wallet, and smart wallets with automatic chain switching, connection persistence, and graceful error handling. Transaction flows include gas estimation, confirmation tracking, optimistic UI updates, and clear error messages that help users understand what happened when something goes wrong.
We implement real-time data updates using WebSocket subscriptions and polling strategies that keep the UI synchronized with on-chain state without excessive RPC calls. For data-heavy applications, we use a combination of direct contract reads for critical state and subgraph queries for historical and aggregate data.
dApps need efficient access to on-chain data — transaction history, event logs, aggregate statistics, and user-specific state. We build indexing infrastructure using The Graph that processes blockchain events and makes them available through a GraphQL API optimized for your frontend's query patterns.
For applications that need data beyond what subgraphs provide, we build custom backend services that combine on-chain data with off-chain state. These services handle user profiles, notification preferences, application settings, and any other state that does not need to live on the blockchain.
Our API layer includes caching strategies that reduce load on RPC providers and subgraph endpoints, websocket connections for real-time updates, and rate limiting that protects backend infrastructure from abuse. The result is a dApp that loads fast and stays responsive regardless of blockchain network conditions.
We deploy dApps with production-grade infrastructure — CI/CD pipelines for automated testing and deployment, monitoring for both smart contract and frontend health, error tracking and logging, and performance optimization for global audiences.
Smart contract deployment follows our structured process with testnet validation, mainnet deployment with verification, multisig ownership configuration, and post-deployment integration testing. Frontend deployment uses modern hosting with CDN distribution, server-side rendering for SEO, and automatic scaling.
Arthiq provides ongoing dApp maintenance and feature development. As your application grows, we add new contracts, build new features, optimize performance, and respond to user feedback. Our Singapore-based team is your dedicated Web3 development partner. Contact founders@arthiq.co to start building your dApp.
