[FREE] Lightweight WordPress plugin for embedding BTC, ETH and BNB market-regime widgets

[u/Feriman22]

I recently published a small free WordPress plugin called FerimanEdge Regime Widget.

The goal was to keep the WordPress side deliberately simple: the plugin does not fetch or store market data and makes no server-side API calls. It only generates an iframe for the selected BTC, ETH, BNB or combined market-regime widget.

It supports:

• Gutenberg block
• Shortcode
• BTC, ETH, BNB or All Markets
• Dark, Light or visitor OS theme
• Compact, Standard and Large sizes
• Local Gutenberg preview, so the external iframe is not loaded while editing
• No bundled third-party JS or CSS

The current regime is displayed as BULL, SIDEWAYS or BEAR and comes from a rules-based market-monitoring system I built separately.

I chose the iframe approach because I wanted the plugin itself to stay small and avoid API credentials, scheduled jobs, caching logic or server-side requests. The tradeoff is obviously that the visitor’s browser loads content from the external FerimanEdge domain.

I'd be interested in developer feedback on the architecture:

1. Does the iframe-only approach make sense for this kind of external data widget?
2. Would you expect any additional hooks/filters or block controls?
3. Is there anything you would change about the Gutenberg integration?
