Clear transaction and gas screens that cut down support tickets
Familiar Web2 patterns layered over your existing smart contracts
Usability testing with real users before the design handoff

AND EVERYONE ELSE

If your scenario isn't listed above, that doesn't mean we can't help.
Fill a form and you'll get:
dApp scoping in 3 days — architecture, smart-contract map, and estimate
Analysis of your concept, tokenomics, and on-chain automation opportunities
Integration recommendations for your existing wallets, chains, and Web3 tools
Signed NDA before the first call

Situations we build dApps for

From a first Web3 idea to scaling an existing product, a different approach for each stage.

You have a Web3 idea but no blockchain team

Hiring Solidity and Rust developers in-house takes months of recruiting before a single line ships. We bring a team that has already built crypto wallets and Web3 apps, so you start building now.
Show details
When this is relevant:
A validated token or product idea that needs to reach a working state fast
No in-house blockchain or smart contract expertise yet
You need a live dApp, not a pitch deck, to show partners
Time to market matters and competitors are moving on-chain
Our approach:
We run a free 3-day scoping session covering tokenomics and chain selection
We architect and develop smart contracts in Solidity or Rust with unit tests
We build the frontend and wallet integration on React or React Native
We hand off full code, or stay on for post-launch support
What you get:
A working dApp MVP in 4 months instead of a year of hiring
Smart contracts written and tested by people who ship them regularly
A 3-day scoping session that fixes architecture and chain choice up front
A predictable budget locked before development starts

Your dApp works but the UX scares off mainstream users

Seed phrases, gas warnings, and desktop-only flows drop a large share of new users during onboarding. We rebuild the experience around patterns people already know from Web2 apps.
Show details
When this is relevant:
High drop-off during wallet creation or first transaction
A desktop-only product that ignores mobile wallet users
Confusing gas and transaction screens generating support tickets
A working backend that needs a friendlier, mobile-first frontend
Our approach:
We audit current flows and find where users drop off
We redesign onboarding with guided steps and plain-language prompts
We rebuild the frontend mobile-first and integrate MetaMask or WalletConnect
We test usability with real users before handoff
What you get:
A mobile-first dApp in React Native covering iOS and Android
Guided onboarding that turns crypto newcomers into confident users
Clear transaction previews and confirmations that cut support load
Familiar Web2 patterns layered over your existing smart contracts

You need to add DeFi or token features to an existing product

Bolting a wallet or token onto a live product means integrating with infrastructure you can't afford to break. The wrong architecture choice here costs months of rework.
Show details
When this is relevant:
An existing fintech or crypto product that needs DeFi features added
A core team already busy with the current roadmap
Plans for a wallet, token, or decentralized exchange functionality
A need to ship without disrupting what already runs in production
Our approach:
We map your current architecture before writing any new code
We build DeFi features as independent modules, not tangled into core
We run async-friendly sprints with daily updates and a shared board
We deliver code review and QA every sprint, production-ready each cycle
What you get:
DeFi modules built as isolated components that are easy to roll back
A dedicated team that joins your workflow within 14 days
Full integration specs and API documentation for your engineers
Handled blockchain connectivity, gas optimization, and error handling

How we build your dApp

We work in 2-week sprints with a demo after each one. From the scoping session to mainnet, you always know what stage the project is at and what ships next.
1

Discovery and architecture

We work through tokenomics, smart contract structure, and chain selection.
Duration: 2 weeks
In a free 3-day scoping session we work through tokenomics, smart contract structure, and chain selection across Ethereum, Solana, or Polygon. Then we detail the architecture and agree on cost and roadmap.
What you get:
A fixed scope and budget, so you plan the project with no surprises
A chain and tech stack recommendation, so the foundation fits the product
A development roadmap, so every milestone is visible up front
2

UI/UX design

We design onboarding, wallet UX, and gas-cost-aware screens.
Duration: 4 weeks
We design onboarding, wallet UX, and gas-cost-aware screens, drawing on familiar Web2 patterns so newcomers aren't lost. Every screen is reviewed with you before development starts.
What you get:
A clickable prototype, so you see the flows before they're built
Mobile-first screens for iOS and Android, so wallet users aren't left out
All designs in Figma, so your team has a ready handoff
3

Smart contract development

We develop smart contracts in Solidity or Rust, cover them with unit tests.
Duration: 6 weeks
We develop smart contracts in Solidity or Rust, cover them with unit tests, and deploy to a testnet. Gas optimization is part of the work, not an afterthought.
What you get:
Tested smart contracts, so logic is verified before real funds move
Gas-optimized code, so transactions stay affordable for your users
A testnet deployment, so you validate behavior before mainnet
4

Security audit

We run an internal security review of the contract code.
Duration: 2 weeks
Our team runs an internal security review of the contract code, and where needed we coordinate an external audit with CertiK or Hacken. Findings are fixed and re-checked before deployment.
What you get:
An internal security review, so known vulnerability classes are caught
An optional external audit, so you have third-party assurance for users
A fixed and re-tested contract, so issues are closed before launch
5

Frontend and wallet integration

We build the frontend in React or React Native and integrate wallets.
Duration: 8 weeks
We build the frontend in React or React Native and integrate wallets like MetaMask, WalletConnect, and Phantom. We wire in decentralized storage and on-chain data where the product needs it.
What you get:
A working frontend on web or mobile, so users reach the dApp anywhere
Wallet integration, so users connect with the tools they already use
On-chain data and storage hooked up, so the interface reflects real state
6

Testnet to mainnet deployment

We ship to production and set up the monitoring to keep it healthy.
Duration: 1 week
We migrate from testnet to mainnet, set up monitoring, and move into post-launch support under an agreed SLA.
What you get:
A live dApp on mainnet, so real users can transact from day one
Monitoring in place, so issues surface before users report them
A post-launch SLA, so support is defined, not improvised

FAQ

How much does it cost to develop a dApp?

It depends on complexity: a simple single-chain dApp with 1–2 smart contracts starts at $40K, a medium project with a contract suite and integrations runs $60K–120K, and a complex cross-chain build with an external audit starts at $120K. We give you an exact figure after a free 3-day scoping session.

What is dApp development services?

dApp development services are end-to-end solutions for building decentralized applications: software that runs on a blockchain network through smart contracts instead of a central server. The work covers smart contract development and audit, frontend and wallet integration, decentralized storage, and post-launch support.

What is a dApp and how does it differ from traditional applications?

A dApp is an application whose backend logic runs on a blockchain via smart contracts, rather than on a company-owned server. That makes it transparent and censorship-resistant: no single party can quietly change the rules or shut it down, and peer-to-peer transactions are recorded on-chain. If you want the longer version, our guide on Web2 vs Web3 breaks down the practical differences.

What are dApps used for?

dApps power use cases where transparency and removing a middleman matter. The common ones are DeFi (lending, token swaps, staking), NFT marketplaces, DAO and governance tools, GameFi and play-to-earn, social and identity apps, and supply chain tracking.

What is the dApp development process at Purrweb?

We work in six stages: discovery and architecture (2 weeks), UI/UX design (4 weeks), smart contract development (6 weeks), security audit (2 weeks), frontend and wallet integration (8 weeks), and testnet to mainnet deployment (1 week). Everything runs in 2-week sprints with a demo after each one.

What blockchain platforms do you build dApps on?

We build primarily on public chains: Ethereum, Hyperledger, Solana, and Polygon, plus BNB Chain and Arbitrum where the project calls for it. For contracts we work in Solidity for EVM chains and Rust for Solana, using tooling like Hardhat and Foundry.

How long does it take to build a dApp MVP?

A dApp MVP takes about 4 months end to end. That covers discovery and architecture, design, smart contract development with testing, a security review, frontend and wallet integration, and deployment to mainnet. A simpler single-feature wallet or minting dApp can ship in around 2 months.

Do you provide smart contract audits as part of dApp development?

Yes. A security audit is built into our process as a dedicated stage, not sold separately after the fact. For products handling significant value, we also coordinate an external audit with firms like CertiK or Hacken.

Can you build mobile-first dApps with React Native?

Yes, and it is one of the things we specialize in. Most dApps are built desktop-first and ignore mobile wallet users, so we build the frontend in React Native to reach users on iOS and Android with the same codebase.

What's the difference between dApp development and blockchain app development?

The terms overlap, but the distinction is where the logic lives. A dApp runs its core logic on-chain through smart contracts on a public network, so it is decentralized by design. "Blockchain app development" is broader and often includes apps that use blockchain for one feature while keeping most logic on a normal backend.

What is DeFi dApp development?

DeFi dApp development means building decentralized finance products: wallets, lending protocols, staking, and decentralized exchanges, where financial transactions run through smart contracts instead of a bank or broker. We build DeFi features as isolated, testable modules so they’re easier to audit and roll back. For the full picture of how we approach this, see our DeFi development company page.

How do you ensure dApp security and gas efficiency?

Security runs through the whole build, not just one stage. Contracts are covered with unit tests, deployed to a testnet for validation, put through an internal security review, and optionally an external audit with CertiK or Hacken before mainnet. Gas efficiency is handled during development, not bolted on later.
