L1X Wallet SDK — Developer Infrastructure
Engineered and published the official L1X Wallet SDK enabling developers to integrate multichain blockchain functionality with clean APIs and comprehensive documentation.
/ The Challenge
Developers building on L1X needed a reliable, well-documented SDK to integrate multichain wallet functionality without needing deep protocol-level knowledge.
/ What We Built
Official L1X Wallet SDK published on npm supporting Ethereum, BSC, Polygon, and native L1X. Clean APIs, optimized transaction handling, comprehensive documentation, regular protocol updates.
Clean API layer abstracting protocol complexity
Multi-chain support across EVM and non-EVM environments
Optimized transaction handling and gas estimation
Built-in security features and key management utilities
Comprehensive documentation and integration examples
/ Outcome
A publicly available SDK on npm enabling the L1X developer ecosystem to build multichain dApps efficiently.
