During March 2025, Catena developed comprehensive Quex Oracle documentation for the OffchainLabs/arbitrum-docs repository, focusing on improving developer onboarding and integration workflows. Catena authored detailed MDX guides that walk users through verifiable HTTP requests from Arbitrum dApps, including API querying, Foundry-based Solidity contract examples, and response post-processing with jq. The work emphasized clear content structuring and traceability, linking documentation updates directly to relevant commits. By leveraging Markdown and Solidity, Catena ensured that the new documentation met quality standards and provided practical, end-to-end guidance for developers integrating Quex oracles, ultimately enhancing the discoverability and usability of Arbitrum’s developer resources.
