Motivation
A) Archives
Archives are an important piece of Polkadot and Kusama data infrastructure provided by Subsquid. They provide access to on-chain data in GraphQL format for all major parachains on Kusama and Polkadot, with more chains getting support as the ecosystem grows. They are being used as a data source for Squids and for efficient data exploration and ad-hoc queries. An up-to-date list of Archives is kept in a public Archive Registry.
The Archives, as performant data sources of historical on-chain data, are critical to the operation of backend APIs run by major projects in the Polkadot ecosystem (the list is not exhaustive):
- Polkassembly
- Talisman
- RMRK
- SubWallet (+ GiantSquid API)
- KodaDot
- Phala dApp
- Subsocial + Polkaverse
- Polkascan (+ GiantSquid API)
- Calamar (+ GiantSquid API)
- Moonsama/Exosama
- Reef
- Manta Wallet
- ZooDAO
- Zenlink
All archives can be accessed and queried via an web intuitive GraphQL interface and are often used as developer friendly replacement of a block explorer. For example, here’s a query for the last ten transfers on Kusama blockchain run against the Kusama Archive endpoint.
Over the third Quarter of 2023 we've provided a free public data indexing service for Substrate blockchains (some archives have been dismissed, new ones have been added), so that everyone interested in the projects can publicly access indexed data on Substrate Events, Extrinsics, Storage Items and EVM logs. Here are projects (parachains and mainnets aiming for future parachains slots) we currently support:
- acala
- aleph-zero-testnet
- altair
- amplitude
- astar
- bajun
- basilisk
- bifrost
- bifrost-polkadot
- binance
- bitcountry-pioneer
- calamari
- centrifuge

B) Giant Squid Giant Squid is a set of open-source GraphQL APIs built with Squid SDK and maintained by Subsquid Labs. The APIs cover the most commonly used data for Pokadot, Kusama and a growing list of major parachains and is used by explorers (such as Calamar) and wallets (e.g. SubWallet).
The Giant Squid currently consists of two families of endpoints outlined below. The API endpoints for each network and the current status are available at the Status page.
Explorer API. The endpoint URLs follow the convention https://squid.subsquid.io/gs-explorer-${network}/graphql. Support queries on:
- Blocks
- Events
- Extrinsics
- Calls
Statistics API. The endpoint URLs follow the convention https://squid.subsquid.io/gs-stats-${network}/graphql. Support queries on:
- Validator/Collator data
- Account balances
- Staking statistics
- Nomination pools statistics
- Transfers statistics
- Extrinsic statistics
Achievements
ArrowSquid release: The main feature introduced by the ArrowSquid update is the new ability of the processor to ingest unfinalized blocks directly from a network node, instead of waiting for the archive to ingest and serve it first. The processor can now handle forks and rewrite the contents of its database if it happens to have indexed orphaned blocks. This allows Subsquid-based APIs to become near real-time and respond to the on-chain activity with subsecond latency.Another major feature introduced by ArrowSquid is the support for transaction execution receipts, traces and state diffs.
Decentralizing Archives: launched public testnet on CoinList with over 40.000 participants (https://coinlist.co/subsquid-testnet). Several thousand indexers in the Subsquid testnet were deployed to index Moonbeam, a Polkadot parachain.
Archive requests increased by over 40% (1.46B requests)
Archives and Subsquid are powering ≈ 650 live projects in Q3 2023
The biggest Polkadot projects have fully migrated or are in the process of finishing the migration from FireSquid to ArrowSquid, including:
- Polkassembly
- Subsocial
- HydraDX
- KodaDot
- Talisman
- Multix Multisig
- RMRK
- Apillon
- StellaSwap
Support continues to be added for new and upcoming Polkadot projects, including new and burgeoning partnerships and Archive implementations with Polimec Protocol, Acurast, Watr, and others.
Statistics and data
Over the course of Q3 2023:
- Served a total of 1,464,029,333 (~1.46 billion) queries to the substrate based archives in Q3 2023
- Served ~500m monthly archive requests for substrate based archives
- The highest daily total responses have been 19.44m in a single 24 hour period for substrate
- The daily queries confirm a growing trend, only partly due to the deployment of new Archives (which initially are not very busy)
Giant Squid is a service we introduced in Q1 2023, and has been launched in mid-January, here are two charts showing its quick adoption by the community, as an index of its success:
Costing
This proposal includes the combined costs for running Giant Squid and Archives for Polkadot, Kusama and their Parachains,which amounts to a total of 45234.77 DOT. Raw data for Archives can be seen here. Raw data for Giant Squid can be seen here.

Subsquid Lab Official has requested funding for ongoing development and maintenance costs for public Subsquid Archives and the Giant Squid API. The proposal includes a total of 45234.77 DOT, which is approximately $298,549.46. The funds will be used to support the operation of backend APIs for major projects in the Polkadot ecosystem, including Polkassembly, Talisman, RMRK, and others. The proposal also covers the costs for running Giant Squid and Archives for Polkadot, Kusama, and their Parachains. The motivation for this proposal is to maintain and improve the accessibility of on-chain data in GraphQL format for all major parachains on Kusama and Polkadot. The funds will help support the increasing number of requests to the substrate-based archives and the growing adoption of the Giant Squid service.
