QuickNode Functions provide a serverless computing environment optimized for blockchain data processing. They allow developers to build, deploy, and run lightweight, stateless or stateful functions at the edge without managing infrastructure. These functions can listen to blockchain events, query and transform blockchain data, and route processed data to various destinations. The platform supports Node.js, Python, ethers.js, web3.js, and the QuickNode SDK, enabling complex operations such as filtering streams, decoding encoded blockchain payloads, enriching data via API calls, and storing key-value pairs for stateful logic. Functions are automatically exposed as APIs, scale globally, and are cost-effective with pay-as-you-go pricing. They support multiple blockchain networks and provide robust security including DDoS protection.
