Monty focused on improving the reliability of EVM CLI RPC interactions within the sei-protocol/sei-chain repository. He addressed an issue where HTTP requests were previously sent as GET instead of POST, which caused inconsistent result extraction and workflow interruptions. By updating core RPC helpers such as getChainId(), getNonce(), and CmdAssociateAddress(), Monty ensured all relevant calls now use POST, aligning with best practices for API development. His work, implemented in Go and emphasizing backend development and testing, resolved the REL-107 issue and reduced debugging overhead, resulting in more stable RPC behavior for both developers and automated systems using the platform.
