SubQuery Ethereum Support - Developer Deep Dive

In this article we share a detailed developer guide for the Ethereum community to use to solve their data indexing needs, including how to migrate from The Graph or use our Managed Service.

SubQuery is an open data indexer that is designed to be flexible, fast and provide universal coverage. Our open indexing tool empowers developers to;

• Build their own API in hours
• Index chains incredibly quickly with the assistance of dictionaries (pre-computed indices)
• Take advantage of multi-threading and optimisation of the store to reduce costly database writes.

Our experience with customers across all verticals in Polkadot, Cosmos, Algorand, NEAR and Avalanche (wallets, networks, explorers, NFT, DeFi, scanners, etc) has helped us build the best Indexer for Developers in web3.

Our Ethereum support is still in its beta, and while we’ve completed considerable testing to ensure that it’s stable, we have further improvements to massively increase the performance and features. Watch this space!

SubQuery Polygon Support - Developer Deep Dive

In this article we share a detailed developer guide for the Polygon community to use to solve their data indexing needs!

SubQuery BNB Chain Support - Developer Deep Dive

Following our recent release of our support for BNB Chain, in this article we share a detailed developer guide for the BNB community to use to solve their data indexing needs, including how to migrate from The Graph or use our Managed Service.

We’re always striving to provide developers with the most comprehensive and efficient indexing solutions possible. Despite being a beta release, SubQuery has already proven to be faster than The Graph on Ethereum and its layer-2s, offering BNB Smart Chain developers another decentralised alternative with the impending launch of the SubQuery Network. That’s why we’re thrilled to announce our latest integration with one of the most exciting Layer-2 scaling solutions in the Web3 space.

About SubQuery

SubQuery is a blockchain developer toolkit facilitating the construction of Web3 applications of the future. A SubQuery project is a complete API to organise and query data from Layer-1 chains. Currently servicing Ethereum, Polygon, BNB, Polkadot, Avalanche, Algorand, Cosmos, NEAR and Flare projects, this data-as-a-service allows developers to focus on their core use case and front-end without wasting time building a custom backend for data processing activities. In the future, the SubQuery Network intends to replicate this scalable and reliable solution in a completely decentralised manner.
