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.
