Zach Miller developed and maintained core features for the Oyl-Wallet/oyl-sdk repository, focusing on advanced Bitcoin and blockchain workflows. Over seven months, he engineered robust Automated Market Maker (AMM) pool management, enhanced UTXO handling, and improved fee calculation for BRC-20 and Rune assets. His work included backend development in TypeScript and JavaScript, with deep integration of Bitcoin scripting and PSBT transaction management. By refining API surfaces, implementing granular data models, and strengthening CI/CD pipelines, Zach delivered reliable, extensible SDK components that improved transaction transparency, developer experience, and operational stability for decentralized finance and token management use cases.

April 2025 was a the Oyl-Wallet SDK delivery sprint focused on strengthening UTXO handling, per-address accounting, and fee/liquidity features. The work delivered safer spend paths, more precise balance tracking, and richer fee economics visibility for users and integrators, enabling stronger business value and future liquidity integrations.
