Developed and delivered the LendaSwap integration for the getAlby/hub repository, enabling non-custodial atomic swaps between Bitcoin and Stablecoins. This feature supports cross-chain swap flows using Lightning and EVM networks, leveraging pay_invoice and make_invoice mechanisms to facilitate Lightning-to-EVM and EVM-to-Lightning transactions. The implementation focused on front end development with React, utilizing both JavaScript and TypeScript to ensure a seamless user experience. Comprehensive onboarding was provided through detailed installation and finalization guides, preparing the feature for app-store deployment. The work expanded the payment-tools ecosystem while reducing custodial risk, addressing user needs for secure, cross-chain asset swaps.
