--- title: Web3 & Immersive description: "Web3, blockchain and XR development services from Miracuves: smart contracts, wallets, exchanges and NFT platforms, plus Unity, Unreal, AR, VR and WebGL builds." url: https://miracuves.com/service/web3-immersive date_modified: 2026-10-29 author: miracuves language: en_US --- Web3 & Immersive # Web3, Blockchain and XR Development Services for On-Chain and 3D Products Two kinds of work share this practice: software that moves value on a blockchain, and software that renders a world in real time. Both punish shortcuts, so each of the fifteen services below is scoped in writing and handed over with every line of source.

[Scope a custom build →](https://miracuves.com/schedule-consultation/) How to choose ## Making the Right Call in Web3 and XR In both halves of this practice, the expensive mistakes are made before any code is written. Option 01 ### Does It Need a Blockchain at All? Use a chain when several parties who do not fully trust each other must share one record, or when users must hold assets that no single company can freeze. If one organization controls the data anyway, a conventional database is simpler to run and easier to change. Option 02 ### Contract First, Interface Second In Web3 the smart contract is the part that cannot be patched quietly after deployment. Settle the token logic, permissions and upgrade path before designing screens, and plan an independent security audit of the contracts before anything goes to mainnet. Option 03 ### Unity or Unreal Unity suits mobile games, AR and titles that must run on modest hardware, with C# scripting and a large asset store. Unreal suits high-fidelity visuals, simulations and console or PC work, with C++ and Blueprints. For lightweight 3D inside a website, WebGL avoids an engine download altogether. Option 04 ### AR, VR or a Shared World AR overlays content on the real world through a phone, so most users need no new hardware. VR needs a headset but gives full immersion for training and simulation. Metaverse builds add persistent shared spaces, avatars and social features on top of either. What you get ## How We Deliver Blockchain and 3D Work Fourteen are fixed-scope builds, and crypto exchange work runs as an ongoing retainer with a demo every week. **9,000+**Projects delivered since 2010**3,900+**Apps published on the stores**6,000+**Clients served**35+**Industries with delivered work[See how each figure is counted →](https://miracuves.com/facts/) ### Included on every engagement - Custom builds run 2 to 8 weeks; an exchange, a full game or a large virtual world is scoped and quoted on paper before work begins. - Contracts, game projects and assets ship as complete, unencrypted source without license check-ins, and any servers they rely on run on infrastructure you own. - Third-party costs such as node providers, engine licenses and API fees stay with you, and we take no revenue share. - Support runs in parallel on every build: platform guidance lasts 60 days, priority bug fixes last 6 months and product evolution lasts 12 months. - The exchange retainer is demoed weekly against an agreed backlog and can be stopped with two weeks notice. FAQ ## Questions About Web3 & Immersive How long does a smart contract or game take to build? A custom build here takes 2 to 8 weeks. A token contract or NFT minting site sits near the short end, while a multiplayer game or a DeFi protocol with several interacting contracts sits near the long end. Anything beyond that, such as a full exchange or an open world, gets its own written scope and price before development starts. Where do I see the price for an NFT marketplace or Unity game? On that service's own page. All fifteen services here publish a figure, and the service page is the authoritative source for it, so this overview lists no numbers. Gas fees, node provider plans, engine royalties and asset store purchases are third-party costs that you pay directly, and they sit outside our figure. Which blockchain should we build on? Choose the chain your users and partners already use. EVM-compatible networks, including Ethereum and its layer-2 networks, share Solidity tooling and wallet support, so contracts and integrations carry across. Pick a non-EVM chain only when it offers something your product genuinely needs, such as a specific ecosystem or transaction model. Fees, finality times and wallet coverage are worth comparing before you commit. Who holds the keys and owns the contracts after launch? You own the contracts, the code and the deployment from day one, and the full source is handed over unencrypted. We recommend deploying contracts and holding admin keys in wallets your own team controls, so no vendor ever sits between you and your users' assets. Infrastructure such as nodes and servers is set up in accounts you own. Can our game or AR app be published under our own name? Yes. App store submission runs from your company's own developer accounts, so the listing, ratings and revenue are yours from the first release. The game or app itself is handed over as full source, so later releases never depend on our accounts or our approval. ## Looking for Another Practice?
