We are excited to introduce our proposal for the Substrate Subsquid Migration to ArrowSquid & Indexing Upgrades. This project targets enhancing the performance and functionality of Subsquid, a vital component providing access to on-chain data within the Substrate ecosystem. Through this proposal, we aim to improve the speed, efficiency, and indexing capabilities of Subsquid, ultimately benefiting developers and users across various chains such as Polkadot, Kusama, Moonbeam, and Acala.
Subsquid currently provides the community with access to on-chain data via GraphQL gateways, serving as data sources for APIs and on-chain data exploration tools. The main objective of this project is to migrate the existing Substrate Subsquid ecosystem to the ArrowSquid processor as well as enhance its indexing capabilities. This migration will enhance the speed and efficiency of all 50+ public squid endpoints.
Currently, all Giant Squid Main squids utilize the previous Substrate processor, Firesquid. The recent upgrade to the ArrowSquid processor introduces significant improvements, such as the ability to ingest unfinalized blocks directly from a network node, resulting in near real-time APIs with subsecond latency. However, this upgrade to the processor resulted in breaking changes and all squids that want to use it have to be adjusted to conform to the breaking changes.
Additionally, Substrate squids currently lack support for indexing Staking and Crowdloans pallets, which contain critical information for various chains in the Substrate ecosystem, including Polkadot, Kusama, Moonbeam, and Acala. The migration will also improve the performance of Polkascan as it depends directly on the data and performance from GiantSquid
The project aims to address these challenges by:
The project will be executed in two milestones. The first one is focused on migrating giant-squid-main to ArrowSquid, which includes upgrading the dependencies, configuration, and endpoints adaptations, as well as testing and deployment. The second milestone will be focused on indexing Staking and Crowdloan pallets calls and events.

Companies Background:
Subsquid is providing the community with access to on-chain data in the form of GraphQL gateways and it is doing it completely for free for the time being. Such endpoints are being used both as data sources for complex APIs and as an on-chain data exploration tool. The purpose of the proposal is to ask for funds to cover the cost of running the infrastructure, given the utility they provide to the community.
LimeChain is a software development company founded in 2017. Positioned to handle end-to-end product development with the capability to manage projects from conceptualization and design to the complete implementation of a certain product. LimeChain specializes in blockchain technology, with an emphasis on developing blockchain-related and infrastructure solutions. In the context of the Polkadot ecosystem, the expertise is focused on developing infrastructure implementations, including Gosemble, a framework for building Substrate compatible Runtimes in Go, Fruzhin, a Host implementation in Java, a framework for runtimes in AssemblyScript, a framework for runtimes in AssemblyScript. On top of that, Limechain has also implemented a Parachain Validation Conformance Testing suite.
Subsquid is a tool that helps people access on-chain data in the Substrate ecosystem, which includes chains like Polkadot and Kusama.
The people behind Subsquid want to make it faster and better by upgrading it to a new processor called ArrowSquid and adding new features like indexing Staking and Crowdloans pallets.
This upgrade will help developers and users access data more quickly and efficiently.
The project will be done in two parts: first, they will upgrade to ArrowSquid, and then they will add the new features.
Subsquid is provided for free right now, but the people behind it are asking for funds to cover the cost of running the infrastructure.
Hello from Polkadotters.
Subsquid is very important for indexing in the Polkadot ecosystem. The upgrade to ArrowSqwuid and introducing of new features such as staking or crowdloans pallets are beneficial for the ecosystem. We are in favor of this referendum. AYE.
