what is xrpl-flow fr?

XRPL Flow is a visual workflow builder for XRPL, the XRP Ledger network. Instead of writing code to build and test ledger transactions, you drag nodes onto a canvas and connect them to build a flow: queries, branching logic, loops, and transaction steps. The tool covers a wide range of transaction types on XRPL, including payments, trust lines, escrows, offers, NFTs, and more advanced features like AMM pools and permissioned domains. A key focus of the project is safety before real money moves. Wallet seeds you import or generate are kept only in your browser tab's memory, never written to disk, and they disappear when you refresh the page. Before any transaction is sent to the Mainnet, it goes through a review step that shows the full details, including fees, destination, and a best effort simulation of what will happen, so mistakes can be caught before funds move. The project is built with a React and Vite frontend, deployed to Cloudflare Pages, with an optional backend for a marketplace of shared workflow templates built on Cloudflare Pages Functions and a D1 database. There is also a local Express server option for development and testing. Running it requires Node.js 20 or newer and the pnpm package manager. The README documents an optional AI assisted workflow drafting feature where you bring your own OpenAI key, but notes plainly that this key is only held in browser memory and could be exposed to malicious browser extensions or scripts, so it should not be treated as production ready without moving that key handling to a server. Workflows are saved as structured documents that get validated on import, checking for things like duplicate connections, unreachable steps, and cycles in the flow graph, to catch broken imports before they run.
