What does Web3 development include at Miracuves?
Full-stack Web3 development at Miracuves covers smart contract design and deployment in Solidity or Rust, React dApp frontend with Ethers.js and wagmi wallet integration, IPFS/Arweave decentralized storage, The Graph data indexing, and mainnet deployment. We deliver the complete decentralized product - not just contracts and not just a frontend.
How much does Web3 app development cost at Miracuves?
A ready-made platform from our catalogue starts from $2,199 and ships in 6 working days; the crypto platforms - the Binance clone, P2P exchange, GMX clone, ICO launchpad and OpenSea clone - carry their own listed prices. Custom Web3 work starts from $3,699, depending on the work. A custom Web3 MVP typically runs $10,000-$40,000 and takes 2-8 weeks; larger scopes are quoted in writing before work starts. Cost scales with the number and complexity of smart contracts, the chains supported, DeFi mechanics such as AMMs, staking or lending, frontend features like wallet integration, real-time price feeds and portfolio dashboards, and oracle or bridge integrations beyond the standard stack. An ongoing retainer starts from $2,299/month for contract and feature work. Every quote is written before payment, with no surprise invoices after kickoff.
Does Miracuves deliver the full source code for smart contracts and frontend?
Yes - completely. Miracuves delivers the full Solidity/Rust contract source, verified deployment addresses, ABI files, React frontend codebase, deployment scripts, and admin panel access. Zero lock-in. Your team or any other Web3 developer can continue the work immediately after handoff.
How fast can a Web3 dApp realistically be delivered?
A ready-made crypto platform - a centralized exchange, P2P exchange, perpetuals DEX, ICO launchpad or NFT marketplace, each with its web app, admin panel and mobile apps - goes live under your brand in 6 working days. A custom Web3 app takes 2-8 weeks; larger scopes are quoted in writing before work starts. All timelines are stated in writing before any payment is requested.
Web3 vs traditional web development - when should you choose blockchain?
Web3 is right when your product genuinely requires decentralization, on-chain ownership, token economics, or censorship resistance. If your users never need to interact with a wallet or blockchain, a traditional React + Node.js stack is faster, cheaper, and simpler. Miracuves will tell you this upfront if Web3 is not the right fit.
What chains does Miracuves deploy Web3 projects on?
Miracuves deploys on Ethereum mainnet, Polygon, BSC, Arbitrum, Optimism, and Solana depending on your project requirements. For NFT marketplaces and social dApps, Polygon and BSC are popular for lower gas costs. For DeFi protocols, Ethereum mainnet or an established layer 2 such as Arbitrum is the usual choice, because that is where most DeFi liquidity has sat. We recommend the right chain during scope review.
Are smart contracts audited before mainnet deployment?
They are reviewed and tested; an audit is a separate, independent step. Every Miracuves Web3 delivery includes Slither static analysis, Foundry fuzz testing and manual review by a senior blockchain engineer before mainnet deployment. For any contract that will hold user funds, Miracuves recommends an independent third-party audit before launch and can coordinate the audit process, with fixes from the audit report built into the schedule.
What happens after the dApp is deployed if there are issues?
Every Miracuves Web3 app delivery includes 60 days of post-launch support, with the indexer and contract events monitored over that window. Bugs within the delivered contract scope, app or backend are fixed at no additional cost; a contract fix ships as an upgrade where the contract is upgradeable, or as a new deployment where it is not, signed by your admin wallet. New features beyond scope are quoted separately, and monthly retainers from $2,299/month cover contract updates and app improvements.
When is Web3 NOT the right choice for my project?
Web3 is NOT the right choice when your product has no need for decentralization, users do not interact with wallets or tokens, your data does not benefit from on-chain immutability, or regulatory requirements in your jurisdiction prohibit cryptocurrency-related applications. For standard web and mobile apps, Miracuves recommends React, Next.js, Node.js or native mobile development instead.
Do you build Web3 mobile apps for iOS and Android?
Yes. Our Web3 mobile apps either connect to the wallet app a user already has through WalletConnect, or include an embedded smart-account wallet so a new user can start with an email or passkey. The same contracts and indexer serve the web dApp and both mobile apps, and we check crypto features against current App Store and Google Play rules before the build starts. The ready-made crypto platforms ship with their mobile apps included.
Can Miracuves build a Web3 super app with a wallet, exchange and payments?
Yes. We start with the shared layer - one sign-in, one KYC record and one wallet - and add the exchange, payments or other products on top, so users verify once and move between features without new accounts. Where a ready-made exchange or P2P platform covers part of the scope, it becomes the base. The licenses each feature needs in your markets are yours to hold; we build the KYC/AML and reporting flows they call for.
Who holds the admin keys to the smart contracts after launch?
You do. Contracts are deployed so that ownership and upgrade rights sit with a wallet you control - ideally a multisig - and deployer and admin roles are transferred to you at launch. Our deploy scripts read keys from environment variables, never from the repository, and once the 60-day support window ends we remove our access unless you keep us on a retainer.
