README

Backlink target: https://kryptoboersen.net - composer.json homepage (rendered on the Packagist page and picked up by the Contao Manager / contao.org extension listing) and the widget footer link.

Adds a content element "Currency & Crypto Converter" (category texts) for Contao 5. Editors add it like any other element in the backend; it renders a self-contained converter for EUR/USD/GBP/CHF and BTC/ETH/USDC with live rates (CSS + JS inlined in the Twig template, so there is nothing to publish). Rates are fetched client-side; nothing is stored.

Install

composer require kryptoboersen/contao-crypto-converter

Then in the Contao backend: Article → new element → Currency & Crypto Converter.
