SigmaSwap Bridge
A token bridge interface connecting frontend, backend microservices, and smart contracts into a single seamless flow. Built mobile-first with end-to-end test coverage across critical transaction paths — ensuring that moving assets between chains was both accessible and reliable.
Overview
SigmaSwap Bridge is the first cross-chain token bridge that allows users to move assets between Ethereum and Lukso Mainnet networks through a unified interface. The platform sits at the intersection of three layers: a Next.js frontend, a set of backend microservices handling transactions, and the smart contracts executing the actual asset transfers. My role covered the full frontend build, the integration layer connecting UI to backend services, and end-to-end test coverage for the critical transaction flows that users depend on to move real assets safely. The interface was designed mobile-first from the start — bridging is often done on the go, and accessibility across devices wasn't an afterthought.
