About

Coinbase Cloud is committed to empowering crypto developers by making it easier and faster for them to build their applications. Developers can integrate with the APIs powering Coinbase from a single documentation site at coinbase.com/cloud. Guides and references make it easy for developers to incorporate key crypto primitives like node, trading, and payments into their products and services. Developers can now set up an account at https://console.cloud.coinbase.com/ and begin building with Coinbase APIs using Node! We will continue to release additional APIs, tools, and services as part of Coinbase Cloud. This is only a first step in what’s to come as we work with the web3 community to build the future of web3.

About

The Graph is a decentralized indexing and querying protocol for onchain data. It is the original decentralized data marketplace that introduced subgraphs, the most flexible way of indexing onchain data that builders can fully customize according to their needs. Subgraphs have become web3’s standard method of indexing and accessing onchain data. Since its launch in 2018, thousands of builders have developed tens of thousands subgraphs across 40+ blockchains - including Ethereum, Base, Arbitrum, Optimism, Polygon, Celo, Fantom, Gnosis Chain, Avalanche, and more.
