Nathan Martin developed and integrated staking capabilities for TLNBTC and lnBTC coins within the BitGoJS repository over a two-month period. Using TypeScript and leveraging his expertise in blockchain and full stack development, he extended the existing lightning coin features to support staking workflows, broadening the asset support and enabling new product functionality. His work involved focused, well-scoped commits that aligned with the staking roadmap, directly addressing business needs for expanded asset capabilities. While the scope was limited to two features and did not include bug fixes, the engineering demonstrated depth in protocol extension and careful integration within a complex SDK environment.
