Eric Sanchirico developed new features for the Uniswap/sdks repository, focusing on expanding the UniswapX SDK to support Hybrid and Permit2 order types through a chain 1301 configuration. He enhanced the routing logic by introducing pathInput-driven routing, which determines the next input currency for multi-pool swaps, addressing complex routing scenarios. Eric implemented comprehensive tests to validate pathInput handling across multiple pools, improving reliability and coverage. His work leveraged TypeScript for SDK design and test-driven development, integrating blockchain concepts and full stack skills. These contributions expanded cross-chain capabilities and improved swap success rates, supporting better developer adoption and robust routing functionality.
