About this Gig
Need a Web3 dApp that real users can use? I build dApps, smart contracts and World App or Base mini apps end to end, from Solidity contract to a fast Next.js frontend.

I also built a blockchain healthcare platform with wallet-based KYC for 10K+ users and premium NFT platforms with tiered utilities. Certified Solidity Smart Contract Developer and AWS Solutions Architect - Professional.
WHAT I BUILD:

- DeFi, NFT and token dashboards

HOW WE WORK:
- A short chat on Fiverr to scope your dApp

FAQ
Which blockchains do you work with?
I work with Ethereum, Base, Arbitrum, Polygon and other EVM chains. Tell me your chain in the order and I will confirm the setup before we start.
Can you connect my existing smart contract to a website?
Yes. Send me the contract address, the ABI and the network. I will add wallet connect and build the screens that read from and write to your contract.
Do you write and deploy smart contracts?
Yes. I write Solidity contracts with tests, deploy to testnet first, then to mainnet, and verify them on the block explorer. For contracts that hold large funds, I recommend an independent audit before launch.
What are World App and Base mini apps?
Mini apps are web apps that open inside World App or the Base app, so users can use your product with their wallet without leaving the app. I lead mini apps used by 185K+ people.
Which wallets can users connect?
MetaMask, Coinbase Wallet and any WalletConnect wallet, plus email or social login with Web3Auth if you want users without a crypto wallet.
Do I own the code and the contracts?
Yes. You get the full source code, and the contracts are deployed so that your wallet is the owner. I never ask for your private keys or seed phrase.
Who pays the gas fees?
Testnet deployment is free. For mainnet, you pay the network gas fees from your own wallet, and I guide you step by step.
My project is bigger than these packages. What now?
Message me with your idea. I will send a custom offer split into milestones, so you pay step by step as features are delivered.
