Web3 Development

Smart Contracts & Blockchain Development

Production-grade DeFi protocols, NFT platforms, and decentralized applications. Solidity, Rust, and Move — deployed across every major chain with the rigor your protocol deserves.

Arthiq is a Web3 development studio headquartered in Singapore, specializing in building production-grade blockchain applications for startups, enterprises, and Web3-native teams worldwide. We write smart contracts in Solidity, Rust, and Move, deploying across Ethereum, Solana, Aptos, Polygon, Arbitrum, Base, and other leading networks.

What separates us from typical blockchain development shops is our Product Owner mindset. We don't just write contracts and hand them over — we challenge your tokenomics, stress-test your architecture, and push for the version of your protocol that actually works in the wild. In Web3, there are no rollbacks after mainnet deployment. We build accordingly.

From DeFi lending protocols and decentralized exchanges to NFT marketplaces, DAO governance systems, and cross-chain bridges — we've shipped contracts that handle real value. Every line of code goes through rigorous testing, security review, and gas optimization before it touches a live network.

What We Build

Full-spectrum Web3 development — from single smart contracts to complete decentralized ecosystems.

DeFi Protocols

AMMs, lending markets, yield vaults, staking systems, and liquidity mining programs. We architect DeFi protocols that are gas-efficient, composable, and secure by design.

  • Automated Market Makers
  • Lending & Borrowing
  • Yield Optimization
  • Staking & Rewards

NFT & Digital Assets

End-to-end NFT solutions — custom ERC-721/ERC-1155 contracts, lazy minting, marketplace integrations, royalty enforcement, and dynamic metadata systems.

  • Custom NFT Contracts
  • Marketplace Development
  • Minting Infrastructure
  • Royalty Systems

DAO Governance

On-chain governance systems with token-weighted voting, delegation, proposal frameworks, and treasury management. Built for transparency and participation.

  • Voting Mechanisms
  • Proposal Systems
  • Treasury Management
  • Token Delegation

Cross-Chain Solutions

Bridge integrations, multi-chain deployments, and cross-chain messaging. Deploy your protocol across multiple networks with consistent state and user experience.

  • Bridge Integration
  • Multi-Chain Deploy
  • Cross-Chain Messaging
  • State Synchronization

Token Engineering

Token economics design, vesting contracts, distribution mechanisms, and ERC-20/ERC-721/ERC-1155 implementation. We model tokenomics that align incentives.

  • Tokenomics Design
  • Vesting Contracts
  • Distribution Systems
  • Incentive Modeling

Security & Auditing

Comprehensive smart contract security — static analysis, fuzz testing, formal verification, and manual review. We catch vulnerabilities before attackers do.

  • Security Audits
  • Fuzz Testing
  • Formal Verification
  • Penetration Testing

Our Technology Stack

We choose technology based on your protocol's requirements — not trends. Our engineers have deep expertise across the major smart contract languages and blockchain ecosystems, and we'll guide you to the right stack for your use case.

For EVM-compatible chains, we work primarily in Solidity with Hardhat and Foundry tooling. For Solana, we build with Rust using the Anchor framework. For Move-based chains like Aptos and Sui, we leverage the Move language's resource-oriented programming model for maximum safety.

Beyond contracts, we build full-stack dApps with React, Next.js, ethers.js, wagmi, and The Graph for indexing on-chain data. Our backend infrastructure runs on Node.js and Python, with custom indexers and event listeners for real-time blockchain data processing.

Web3 Development FAQ

Common questions about our blockchain and smart contract development services

We build on all major EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base, Optimism, BNB Chain), as well as Solana, Aptos, and Sui. We help you choose the right chain based on your product requirements — transaction speed, cost structure, security model, and ecosystem fit. Most of our DeFi work targets Ethereum L2s for the balance of security and gas efficiency.
Yes. Every smart contract we develop goes through our internal security review process including static analysis, unit testing, fuzz testing, and manual code review. For high-value protocols, we also coordinate with independent third-party audit firms. We can also audit existing smart contracts that were built by other teams.
We write production smart contracts in Solidity (Ethereum/EVM chains), Rust (Solana, Near), and Move (Aptos, Sui). Our team also has experience with Vyper for specialized use cases. We choose the language based on the target chain and your specific requirements.
A focused DeFi protocol — such as a lending market or AMM — typically takes 3-5 months from architecture to mainnet deployment. This includes contract development, comprehensive testing, internal audit, testnet deployment, and mainnet launch. More complex protocols with multiple interconnected components can take 6-9 months.
Absolutely. We regularly build integrations and extensions on top of Uniswap, Aave, Compound, Chainlink, and other established protocols. Whether you need a custom vault strategy, a yield aggregator, or a protocol-level integration — we understand the composability of DeFi and can build on existing infrastructure.
We cover the full stack. While smart contracts are our core strength, we also build the frontend interfaces (React/Next.js), backend services (Node.js, Python), indexing infrastructure (The Graph, custom indexers), and DevOps pipelines. One team, end to end — no subcontracting.
