The Challenge Cross-chain swaps are complex and fragmented, leading to poor user experiences and dropped transactions across blockchains. The Solution I designed a cohesive interface for LI.FI’s SDK, enabling users to perform cross-chain swaps with ease while integrating with multiple protocols and liquidity sources. The Results - Increased swap success rates by 35% during testing. - Reduced average swap time by 25%, ensuring smooth cross-chain interactions. Process Overview 1. Research Conducted usability analysis of current cross-chain solutions, identifying common pain points like unclear fee structures and complex flows. Prioritized transparency and simplicity in swap processes. 2. Design Developed a step-by-step swap interface with real-time progress tracking. Integrated key features such as fee estimations, token approvals, and swap previews in a single flow. Designed a modular SDK that businesses can customize to match their branding and workflows. 3. Testing & Iteration Worked with Web3 developers and crypto-native users to refine the design. "Finally, a cross-chain flow that feels reliable and easy to use." – User feedback. Key Takeaway Creating the LI.FI SDK reinforced the need for clear, user-centered design in DeFi solutions, especially for reducing friction in complex technical interactions like cross-chain swaps.
