Blockchain & Crypto App Dev

$10/hr Starting at $500

Building a crypto wallet or Web3 app is not like building a regular application. The security requirements are completely different, key management demands careful engineering, and the UX has to be smooth enough that non-technical users can operate it without making costly mistakes. This is specialized work — and I have been doing it long enough to know exactly where the hard problems are.


I build custom crypto wallet apps for iOS and Android — multi-chain support, client-side transaction signing, and secure private key management done right. My Web3 development covers:


  • Smart Contracts — Solidity on Ethereum, BNB Chain, and EVM-compatible networks
  • NFT Platforms — minting, listing, bidding, royalty logic
  • DeFi Apps — liquidity pools, staking, yield farming interfaces
  • Token Development — ERC-20, BEP-20, custom tokenomics


Every smart contract is thoroughly tested before deployment and can be independently audited. If you are building a crypto product and need an engineer who handles both the blockchain layer and the full application — let's build it.
