About this Gig

Building a crypto wallet is not about UI it is about secure key management, deterministic signing and reliable on-chain execution. I develop crypto wallet apps that handle real assets safely across multiple blockchain networks.


I specialize in ETH, Smart Contracts and React Native wallet UI, Supporting ETH, SOL, Polygon, and Bitcoin. I build Non custodial , Multi-chain wallets with DeFi integration, Including ERC20/SPL token support, HD wallet derivation, seed phrase flows, gas estimation, and accurate transaction broadcasting. My architecture ensures seamless interaction between frontend wallets and blockchains nodes using ether.js and Web3.js.


I've delivered mainnet-ready wallet applications with active users and maintain clean, auditable Solidity codebase.


If you need a secure crypto wallet app, blockchain developer, or Web3 wallet solution, message me to discuss your project architecture before development begins.
