Crypto Converter ⚡ Widget

Live converter for ≈14k crypto, fiat and commodity symbols: Gutenberg block, shortcode, themes and no API key.

📌 Description

Crypto Converter Widget adds a lightweight, customizable converter to WordPress. Use it as a Gutenberg block, shortcode, or widget-area embed to show live crypto, fiat, token, blockchain, and commodity conversion on posts, pages, and sidebars.

The plugin is built around a browser-native Web Component, so the public markup stays simple and the interface remains easy to customize from WordPress. Standard usage does not require API keys or server-side setup.

It supports ≈14k crypto symbols plus fiat and commodity entries. You can configure base and quote assets, amount, decimal precision, locale, tax/fee adjustment, fiat symbols, light/dark/auto themes, rounded corners, borders, shadows, custom colors, and gradients.
