Worked on PolyhedraZK’s PolyhedraDocs repository to deliver targeted documentation corrections for EXPchain’s JSON-RPC endpoints, focusing on improving onboarding and integration reliability. Addressed a critical bug by updating Markdown-based documentation to reflect current network configurations, including clarifying testnet usage and correcting the Multicall contract address. The approach involved aligning endpoint details with live network data and updating usage examples to reduce the risk of misconfiguration for developers. Leveraged skills in technical documentation and Markdown to enhance deployment readiness, ensuring that integration guidance remains accurate and actionable for developers working with EXPchain’s evolving testnet and mainnet environments.
