The Problem
Your Web3 App Works on a Laptop and Breaks on Launch Day
Web3 products often split across a contract developer, a web freelancer, and an app team. Each part works alone, and the gaps between them show up when real users arrive.
01 · Mobile wallets
On phones, the wallet prompt opens and the session drops.
We test wallet connection on real iOS and Android phones first.
02 · Slow pages
Profile and listing pages read the chain on every visit.
An indexer stores on-chain events, so web and mobile pages load from a fast API.
03 · Split vendors
Three vendors split the contract, web, and app work.
One team builds the web front end, the API, and the app, and integrates your contracts.
04 · Unclear results
Users can't tell if a transaction worked, so they sign it twice.
Each transaction shows a pending, confirmed, or failed state read from the chain.
Your launch is announced for Friday, and the app works on the founder's laptop. On a phone, the wallet prompt opens and the page loses the session. Profile pages read the chain on every visit, so they crawl. Users can't tell whether a transaction worked, so some sign it twice. The contract developer, the web freelancer, and the app agency each blame the other's code, and nobody can say which flows have run on a testnet.
We start with a free Web3 review that walks each flow your users take: connect, sign, wait, and see the result. Then one team builds the web front end, the API that serves indexed chain data, and the iOS and Android app. Wallet connection gets tested on real phones first, and every flow runs on a public testnet before mainnet. Users approve each transaction in their own wallet, and we don't ask anyone for seed phrases.
Wallets that connect on phones
MetaMask, Coinbase Wallet, and WalletConnect flows are tested on iOS and Android before the rest is built.
Fast pages from indexed data
An on-chain event indexer feeds an API, so profiles, listings, and the app load without waiting on the chain.
Testnet before mainnet
Mints, listings, and contract calls run on a public testnet such as Sepolia before real funds move.
Our Services
Web3 Application Development Services for Sites, Apps, and APIs
Start with the layer your launch depends on: the web app where wallets connect, the mobile app your users carry, or the API that serves chain data fast. Each one works with the others when you add them.

Who We Build For
dApp Development Services Matched to What You're Launching
An NFT creator needs a mint page that holds up on launch night, while a crypto app team needs an API and two store releases. Choose the launch that looks most like yours to see which services we pair and how long it usually takes.

Run a mint night that holds up
Your collection is ready and the date is public. When the whole community arrives at once, the page, the wallets, and the contract all have to work.
NFT creators planning a public mint: Your mint date is announced, the allowlist is full, and the last drop you joined elsewhere failed on mobile wallets.
- A mint page with allowlist phases
- Wallets tested on phones first
- Holder questions answered by a bot
Plan this setupTypical timeline: 3 to 6 weeks
Our Process
From Free Web3 Review to Mainnet Launch in Five Steps
You approve the flow map and price first, try every flow on a testnet with your own wallet, and launch on mainnet only after you sign off.
We walk through each flow your users take, from connecting a wallet to seeing the result, and read your contract's functions. You get a written list of what to build, what to test, and what can wait.

What Our Clients Say
What Clients Say After Launch
A founder and other clients on how their builds went, from delivery to the support after launch.
We had a very specific vision for our website & app, and DeveloperLook not only delivered but added features we hadn’t even thought of. Their guidance and creativity made the project a huge success.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.

Not a fit
Exchange or custody
You want crypto exchange development services or a custody product. Exchanges and custody are regulated, so a qualified lawyer should shape the plan before any build.
A new blockchain
You want a new Layer 1 chain or a custom consensus protocol. We build apps on existing networks such as Ethereum, Polygon, and Base, not new chains.
Contract audit only
You only need an independent audit of a finished contract. That's work for a dedicated audit firm, and we can integrate the audited contract afterward.
Budget under $1,300
Your budget is under $1,300 and you only want to test interest with a small drop. A no-code minting tool will run that first test for less.

Blockchain app development with us starts at $1,300 for a tested app prototype and $1,450 for an NFT mint site or a focused API. An NFT marketplace MVP starts at $4,400, and a marketplace with an iOS and Android app starts at $9,100. Independent audits and gas fees are paid by you directly, outside our price.
A tested app prototype takes about 2 weeks, an NFT mint site 3 to 5 weeks, and a focused API 2 to 3 weeks. An NFT marketplace MVP takes 8 to 12 weeks, and adding an iOS and Android app brings it to 12 to 16 weeks. Contract readiness and any audit usually set the launch date.
dApp development is building a decentralized app: a front end where users connect a wallet, plus smart contracts that run its logic on a blockchain. Most dApps also need an indexer and an API, because reading the chain directly is slow. We build the front end, the API, and the app, and integrate your contracts.
Blockchain application development is building software whose key records, such as ownership or payments, live on a blockchain instead of a private database. The app reads and writes those records through smart contracts and the user's wallet. Everything around them, like search, alerts, and dashboards, is still normal web and mobile engineering.
A blockchain app is any app that reads from or writes to a blockchain, usually through a crypto wallet the user controls. NFT marketplaces, crypto portfolio trackers, and token-gated communities are common examples. To the user it should feel like a normal app, with the wallet step explained in plain words.
Web3 apps keep key records, such as who owns a token, on a public blockchain instead of one company's servers. Users sign in and approve actions with a crypto wallet that holds their keys. Smart contracts apply the rules, and the website or app is the interface on top. Gas fees pay the network to process each transaction.
Yes, for standard cases. We deploy ERC-721 and ERC-1155 contracts built on OpenZeppelin's widely used libraries and connect them to your app. Custom logic, such as auctions, gets its own scope and price. Before any contract holds user funds on mainnet, we recommend an independent audit, even when we wrote it.
Most builds run on Ethereum or an EVM network such as Polygon or Base. Users connect with MetaMask, Coinbase Wallet, or any wallet that supports WalletConnect. Every flow runs on the chain's public testnet first. For Solana or another non-EVM chain, we check the fit before we quote.
Pick one that shows working testnet builds, not just designs, and explains how users sign each transaction. Ask whether they ever hold private keys (they shouldn't), who owns the contract roles after launch, and how they test wallets on phones. A custom blockchain app development company should also say when a no-code tool would do.
You do. At launch, the contract owner roles pass to your team's wallet, and the code, domain, and hosting sit in your accounts. We document each admin function and keep no keys to your contracts. Support runs 30, 60, or 90 days by plan, and upgrades after that can go on a care plan.
