NowBank
A decentralised finance exchange built on Binance Smart Chain with DeFi protocol integrations.
NowBank is a decentralised web application and DeFi exchange built on the Binance Smart Chain (BSC), developed for a fintech company based in Estonia. The platform enables users to swap tokens, interact with DeFi protocols, and manage on-chain assets through a seamless, non-custodial interface.
I worked as Blockchain Developer on the full product — designing and deploying Solidity smart contracts for secure, gas-optimised on-chain transactions, building the React frontend with Web3.js and Uniswap SDK for wallet connection and token swapping, and integrating DeFi protocols to extend the platform's financial capabilities.
Deployed smart contracts on BSC with zero critical vulnerabilities
Integrated Uniswap SDK for real-time token swap pricing
DeFi protocol integrations expanding platform functionality
Non-custodial architecture — users retain full control of assets
