Sparkplate

Sparkplate provides a set of Vue components and helper methods for interacting with multiple cryptocurrency services. Its core feature is a test page that translates human‑readable domain names into corresponding crypto addresses, allowing developers to verify resolution logic in a browser environment. The library is packaged for macOS and is marked as stable, indicating readiness for production use.

The package bundles integration points for a range of APIs, including Alchemy for Ethereum transaction history, Blockchair for Bitcoin, Dogecoin, and Litecoin data, and CoinMarketCap for live market information. It also supports Changelly for currency exchange, Infura for Ethereum connectivity, WalletConnect for web3 wallet interactions, and the Wert widget for purchasing crypto.

Developers configure required credentials by setting environment variables such as VITE_ALCHEMY_API_KEY, VITE_BLOCKCHAIR_API_KEY, and others listed in the documentation. Installation follows standard npm workflow, and the test page can be launched locally with npm run dev.
