dApp
Development

A Web3-native decentralized application that connects modern web frontends directly to on-chain ecosystems.

$400 – $1,500 · 2–3 weeks

Architecture

Built for Web3

A dApp is only as good as its connection to the chain. The architecture is built around five layers that keep wallet state, blockchain data, and contract interactions fast, secure, and intuitive — so users sign, mint, stake, and claim without friction.

Wallet authentication & signing

MetaMask, Phantom, WalletConnect, and embedded-wallet login with signature-based identity so users control their own accounts.

RPC node & network layer

Reliable Alchemy or Infura connections with network detection and auto-switching so the app always talks to the right chain.

On-chain read/write interface

Clean frontend controllers that fetch balances, NFTs, and contract state — and prompt the wallet only when a transaction is required.

Token-gated UI & permissions

Hide or unlock dashboards, premium pages, and actions based on the assets held in the connected wallet.

Mobile-first React/Tailwind frontend

A fast, responsive interface that works seamlessly with mobile wallet deep-links and browser extensions.

What we can build

The Crypto Launchpad Portal

A frontend for managing a private sale allocation, allowing whitelisted users to connect wallets and secure one of exactly 70 exclusive distribution slots.

The Token-Gated Community Hub

A decentralized portal that verifies if a user holds a specific asset before granting access to a paid WhatsApp community, private Luma workshop, or premium resources.

The Staking & Yield Dashboard

A clean UI where users lock up tokens, track dynamic APY rewards in real-time, and execute claim transactions securely.

The NFT Minting Page

A single, high-converting landing page built for a digital collectible drop, with a live countdown, total minted counter, and direct execution flow.

FAQ

Which chains do you support?+
EVM chains by default (Ethereum, Base, Polygon, Arbitrum, Optimism, BNB Chain) and Solana. Other chains (Cosmos, Sui, Aptos) are possible but scoped separately.
Do I need to already have smart contracts?+
No. This package is the frontend and wallet layer. If you also need the contracts written, add the Smart Contract Engineering package — bundled pricing available.
Who covers gas fees for testing and deployment?+
You do — I request a small testnet + mainnet gas budget upfront. Real gas is paid from your wallet, not folded into my rate.
Can users sign in with email instead of a wallet?+
Yes — I can wire embedded wallets (Privy, Dynamic, Web3Auth) so users sign up with email/Google and get a wallet under the hood. Adds ~$400–$600.
Do you handle mobile wallet deep-linking?+
Yes. WalletConnect v2 and mobile deep links are included so Trust Wallet, Rainbow, and MetaMask Mobile work out of the box.
