QuickNode's Core API provides developers with fast, reliable, and scalable access to multiple blockchain networks via a unified API. It simplifies blockchain interaction by handling node infrastructure, upgrades, forks, and network interruptions, allowing developers to focus on building decentralized applications (dApps), tokens, and NFTs. The API supports all major blockchains including Ethereum, Binance Smart Chain, Polygon, Solana, Bitcoin, and more, with ultra-low latency and 99.99% uptime SLA. It integrates easily with popular Web3 libraries and offers features like real-time analytics, archive access, trace/debug capabilities, and strong security measures such as token-based authentication and domain whitelisting. QuickNode also provides developer tools, dashboards, and a marketplace for add-ons to extend functionality.
