Sean Chen developed the Starknet Client Creation CLI for the informalsystems/ibc-starknet repository, focusing on streamlining the process of provisioning Starknet relayer clients. Leveraging Rust and the Cosmos SDK, Sean designed a cohesive command-line interface that integrates Starknet-specific options with Cosmos chain configurations, enabling users to create new clients efficiently. The CLI features robust argument parsing, subcommands, and enhanced error handling to reduce onboarding friction and standardize client setup. By automating the client creation workflow, Sean’s work established a reproducible foundation for future deployments, accelerating end-to-end integration between Starknet and Cosmos and improving developer and operator productivity.
