I started where I’m most comfortable: Figma. I reviewed Bitchat’s existing UI then quickly sketched wireframes imagining how a Cashu wallet might fit into the existing app. Tried to keep the IRC / TTY vibes and UX.
Next I set up the Figma x Cursor MCP bridge that lets cursor directyl read Figma frames. This took some back and forth. I didn’t want new type styles or colors cluttering up the codebase. My prompts explicitly referenced the existing theme and typography kotlin files.
