@Adeyemi-cmd has applied to work on this issue as part of the Stellar Wave Program's 4th wave.

I would love to take this on as a developer with hands-on experience in CLI tooling, SDK integration, and developer experience design building a clean, config-driven proof-of-concept CLI that wraps the SDK’s core modules, ships a working balance command, and gives contributors a well-documented launchpad for expanding SDK actions from the terminal.
