Web3 Development Process

Web3 development involves a strict workflow to reduce risks and achieve the desired results.

Research & Planning We formulate objectives, conduct market analysis, choose the best blockchain. We develop a detailed technical specification that becomes a foundation for the web3 project development.

Architecture and Prototyping We design the entire architecture of the project including all Web3 integrations. All UX/UI prototypes will be validated before the development stage.

Development Development of smart contracts in Solidity or Rust, and front-end and back-end development in parallel. Connecting Web3 wallets and other components is performed at this step.

Testing and Auditing Conduct unit, integration, and load tests for all parts of the system. Security check for smart contracts by Nomium. External auditing of contracts on request.

Launch and Post-Launch Support Start in testnet and move to mainnet if everything is in order. After launch, we offer monitoring and incident response for your product. Token launch, DAO setup, and liquidity bootstrap are available upon request.

We will prepare a commercial proposal detailing scope, timeline, team structure, and cost.

Upon agreement, development begins.

FAQ

How do I choose the right Web3 development company?

The best option is a company with extensive production experience, smart contract audits, clear testing details, post-launch support, and verified case studies. As a web3 app development company, Nomium works exclusively in the blockchain and Web3 space and is deeply experienced.

What services do Web3 development companies offer?

Typically, firms provide smart contract development and auditing, development of decentralized applications (dApps), DeFi protocol engineering, NFT marketplace development, crypto wallet development, and blockchain services integration. At Nomium, all these services along with technical consultations are offered.

How much does Web3 development cost?

Costs depend on the complexity of contracts, blockchain of choice, frontend scope, and audit requirements. Simple token contracts with basic dapps are cheaper than complex DeFi protocols. We provide an estimate after the initial call, not using generic rate cards.

What are the advantages of Web3 development for businesses?

Cost savings, transparency, global accessibility, and tokenization of digital assets are the main benefits of Web3 development. In terms of business, benefits are most pronounced in B2B use cases.

How does a Web3 development company ensure security of the products?

We apply security principles from the very beginning. We prevent reentrancy, overflow, access control issues, and front-running vulnerabilities. Our contracts are audited internally. High-risk contracts undergo third-party audits before release to mainnet.

What is the typical Web3 application development process?

Web3 application development includes five steps: research and scope definition, architecture and UX prototype validation, development, testing and auditing, and launch with post-launch support. Typical timeline: 4-6 weeks for a simple dapp, 3-6 months for a full DeFi protocol.

Which technologies and platforms are used in Web3 development?

Main programming languages are Solidity and Rust. Among blockchains – Ethereum, BNB Chain, Solana, Polygon, Avalanche, Arbitrum. Frontend tools include ethers.js, wagmi, and web3.js. Backend is built with NestJS and Node.js.

What are the most common Web3 application use cases?

The most common web3 use cases are dapps, decentralized finance (lending, trading), gaming platforms, NFT marketplaces, DAOs and tokenization, crypto wallets, and mining pools. Nomium has hands-on experience across most of these categories.

How long does it take to develop a Web3 solution?

Development time depends greatly on project complexity. A minimal dapp may be built in 4-8 weeks; a full DeFi platform takes 3-6 months. Our business analyst will provide an accurate development timeline after the discovery call.

What challenges might a business face when adopting Web3 technology?

Challenges include choosing the right blockchain, designing smart contracts to allow future upgrades, managing gas costs, and making UX intuitive for users unfamiliar with Web3 and wallet interaction. We can advise on all of these during a technical consultation.
