This week’s ARK development report highlights the continued hard work of our talented team. We’ve made significant progress on key projects and features, delivering a packed update on advancements in Mainsail, ARK SDKs, ARK Vault, and more. Key Highlights: Our developers focused on improving user experience through design updates across various applications, such as the updated transaction details modal and improved dropdown styling. We also enhanced the ARK Scan team’s work with fixes for pending transactions, addressing validator page errors, and updating the UI to align with recent design changes. **Here’s a closer look at the progress made:** 1. **Mainsail Development**: We released two new testnet versions packed with fresh features, bug fixes, and performance improvements. The team also focused on refining and enhancing the Mainsail experience through various iterations, including adjustments for modal styling and integration of unified translation handling across all components. 2. **ARK SDK & Documentation**: The TypeScript Client SDK received a fix to enhance pending transaction support.
