Halliday Claude Code Plugin Demo
Build a crypto deposit and onramp app in minutes using the Halliday Claude Code plugin. In this walkthrough, I use the plugin to scaffold, build, and run a working app that lets users onramp from fiat or swap to any output token — then I show a real payment in production, including the onchain transaction landing in my wallet.
The Halliday Claude Code plugin is your own Halliday developer in the terminal, available 24/7. It can answer integration questions, clone any of 10+ open source example apps, review your existing Halliday integration for correctness, and even look up and debug production payments directly against the API.
No API key yet? The plugin walks you through creating a Halliday Dashboard account and generating one for you.
The plugin is open source on GitHub: https://github.com/HallidayInc/Hallid...
Install instructions and docs: https://docs.halliday.xyz/pages/llms-...
