Greptile Overview

Summary

Updated the Memento demo chain RPC endpoint to use a proxy URL (https://memento-demo.common-prefix.workers.dev/) instead of an empty string, enabling proper RPC connectivity for testnet deployments.

• Added RPC proxy URL for memento-demo chain in testnet configuration
• Added # skip-check markers to external GitHub commit links in Hedera ITS release documentation (likely to prevent CI link validation failures on external repositories)

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• Changes are straightforward configuration updates: adding an RPC endpoint URL and marking external links to skip validation. No logic changes, no security implications, and changes are isolated to configuration files
• No files require special attention
