QuickNode - AWS for Blockchain

Introduction

Quicknode allows high-performance access to blockchains like Ethereum (as well as most ERC-20 compatible blockchains like Polygon, xDai, etc) and Solana. This plugin makes it simple to power your blockchain applications built on Bubble and scale up as you grow. From elastic APIs & dedicated nodes to powerful tools & analytics, all at your command through a simple control panel. You can get an instant access to both Mainnet and TestNet networks.

QuickNode Ethereum RPC Overview
At QuickNode, we run Ethereum RPC endpoints. In aggregate, we serve more than 50 billion requests every month. To make it easier for developers to integrate with QuickNode, we've created this document that shows how to call RPC methods using libraries in Python, Ruby, JavaScript, cURL.With QuickNode, you either have a dedicated endpoint that is always serving traffic from the same location as designated when you booted the endpoint or you get access to our global network which always routes to the nearest available endpoint.

Solana API Call

QuickNode Solana RPC Overview
At QuickNode, we run Solana RPC endpoints. In aggregate, we serve more than 50 billion requests every month. To make it easier for developers to integrate with QuickNode, we've created this document that shows how to call RPC methods using libraries in Python, Ruby, JavaScript, cURL.With QuickNode, you either have a dedicated endpoint that is always serving traffic from the same location as designated when you booted the endpoint or you get access to our global network which always routes to the nearest available endpoint.
