During November 2025, Sayan Kar enhanced the ava-labs/builders-hub repository by consolidating and expanding Avalanche Client SDK documentation, focusing on account management, transaction workflows, and multi-chain operations to streamline developer onboarding. He introduced a wallet creation workflow and addressed onboarding friction by adding missing examples. Sayan also authored comprehensive Interchain SDK documentation, detailing cross-chain messaging and token transfer setup with practical TypeScript code samples. To improve maintainability, he developed a script in TypeScript that merges code samples from Speakeasy OpenAPI specs into Glacier and Popsicle API documentation, ensuring consistency and reducing support overhead through automated, standardized documentation generation workflows.
