Today, we are excited to announce full SubQuery support for Scroll’s final and latest testnet on Sepolia. SubQuery's indexing capabilities empower Scroll developers to efficiently manage and query on-chain data, expediting development processes and facilitating rapid iterations, ultimately advancing the goal of onboarding the next billion users to the blockchain.

Scroll is a new zkEVM-based zkRollup on Ethereum that enables native compatibility for existing Ethereum applications and tools.

Now, developers in Scroll can take advantage of SubQuery's versatile, high-speed, open, and decentralised data indexing solution, equipping blockchain developers with essential tools for efficiently managing and querying on-chain data for their protocols and applications. By abstracting the backend complexities, SubQuery delivers a custom API, allowing developers to prioritise product development and user experience instead of dedicating resources to building their own indexing solutions

“We are committed to offering the finest experience to developers and users alike, that means providing developer tooling and services to make it easy to build, deploy, iterate, and scale your applications on Scroll. We're delighted to welcome another multi-chain indexer into our ecosystem and excited that developers can leverage SubQuery to craft cutting-edge applications on Scroll.”
—The Scroll Team

We continuously aim to offer developers the most extensive and efficient indexing experience, encompassing open-source SDKs, tools, comprehensive documentation, and dedicated developer support available within the SubQuery ecosystem. Additionally, we're proud to extend our support for Scroll to our enterprise level managed service, which handles hundreds of millions of daily requests, ensuring robust infrastructure hosting.

Furthermore, with the upcoming launch of the SubQuery Network, we are poised to provide Scroll developers with yet another decentralised indexing solution. This is why we're excited to announce our latest integration with one of the most promising EVM chains in the Web3 realm.

“We are excited to announce the integration of SubQuery's data indexing solution into the Scroll community. This solution, celebrated for its versatility, speed, transparency, and decentralisation, will streamline intricate backend processes. Our objective is to empower developers within the Scroll community to focus squarely on their core objectives: creating outstanding products and elevating the overall user experience. Our dedication to Scroll aims to spark inspiration among web3 pioneers, propelling us into a new era of captivating decentralised applications.”
— Sam Zou, Founder and CEO of SubQuery

Our experience with customers across all verticals in Ethereum, Polygon, Polkadot, Cosmos, Algorand, NEAR and Avalanche (such as wallets, networks, explorers, NFT, DeFi, and scanners, etc.) has helped us build one of the best performing Indexers for developers in web3.

SubQuery is currently focused on decentralising and tokenizing the protocol to build the SubQuery Network. The SubQuery Network will index and service data from projects to the global community in an incentivized and verifiable way and support indexing Scroll projects, and those from any other supported network from the outset.


Why Use SubQuery?

SubQuery offers remarkable flexibility, enabling external API calls and the integration of external libraries within your mapping functions. It also provides enhanced control for running projects on your infrastructure, complete with automated denial-of-service (DOS) mitigation controls. Importantly, we want to emphasise that there are no plans to discontinue our managed service.

When it comes to speed, SubQuery truly excels, especially when dealing with the indexing of vast numbers of blocks. This speed advantage becomes crucial when selecting your indexer. SubQuery achieves this by employing multi-threading and optimising the store to minimise resource-intensive database writes. The result? Faster synchronisation times that empower developers to iterate swiftly and bring new features to market with remarkable speed.

Last but not least, in just a few months, you'll have the opportunity to fully decentralise your SubQuery infrastructure with the impending launch of the SubQuery Network. This network represents the future of Web3 infrastructure, with the capacity to index and serve your project's data to the global community in a secure and incentivized manner. It's crafted to accommodate any SubQuery project, regardless of the supported network, including Scroll. This means you can harness the vast scale of the unified SubQuery Network right from the very beginning.

Getting Started with SubQuery and Scroll

The best way is to start by following our step-by-step guide using a real-world example project. Follow our quick start tutorial to index all transfers and approval events from the Wrapped Eth on Scroll's Sepolia Test Network.

With SubQuery’s Scroll integration, there are three types of mapping handlers:

  • BlockHandler: All blocks and their hash and height
  • TransactionHandler: All transactions and their hash, height, and timestamp
  • LogHandler: On each and every log that matches optional filter criteria, access various data from the Scoll logs

We’ve updated the SubQuery Documentation to add Scroll’s specific information to the general SubQuery documentation.
