About this gig

Need a crypto wallet app, blockchain app, DeFi wallet, trading app, or crypto exchange app built for real users? I develop secure, scalable Web3 and cryptocurrency platforms designed around your business model, users, and growth goals.


You are not buying a pile of generic code. You are building a product that needs to work reliably, look professional, protect user assets, and be ready for the next stage of your business.


I will develop your crypto wallet, DeFi wallet, blockchain application, trading platform, or crypto exchange with the right architecture and integrations for your requirements.


Depending on your project, I can build features such as:

  • Multi-chain crypto wallet functionality
  • Send, receive, swap and transaction tracking
  • DEX/CEX and crypto exchange functionality
  • Web3 and WalletConnect integration
  • Token, blockchain and smart contract integration
  • Staking, liquidity and DeFi features
  • KYC/AML and secure authentication
  • Crypto payment and API integrations
  • Admin dashboard and user management
  • Responsive iOS, Android and Web applications
