Subsquid and Moonbeam Collaborate for Better Cross-Chain and EVM Data Processing

3 min readMar 17, 2022

Subsquid and Moonbeam are thrilled to announce a new joint effort to accelerate application development in the already rapidly growing Polkadot ecosystem. By bringing Subsquid’s data-processing and API development framework to Moonbeam and Moonriver (Moonbeam’s Kusama deployment), this collaboration is set to make it easier, faster, and more resource-efficient for Web3 builders to develop, deploy, and maintain highly user-friendly cross-chain applications.

The Subsquid and Moonbeam teams have long shared the common goal of bringing together the best features of both the Polkadot and Ethereum ecosystems. As an EVM-compatible layer-1 smart contract platform with a Substrate base layer, Moonbeam enables developers to build DApps using programming languages that they are already familiar with, such as Solidity and Vyper. Subsquid has taken the same approach, configuring its API development framework to include EVM support and Substrate capabilities that extend across many parachains.

Subsquid Archives have already been deployed for both Moonbeam and Moonriver, and multiple Squid APIs are planned on these networks. For example, a Squid that indexes data for Litentry’s user-centric identity solution is already under development. The Subsquid team is also working on use-case-specific Squids that will provide EVM transaction data to wallets, including to Nova Wallet and Subwallet.

“Data indexing platforms are a critical part of the web3 developer toolkit, but they have historically been focused on isolated blockchain data sets and APIs,” says Derek Yoo, founder of Moonbeam. “But apps are shifting to multichain architectures supporting cross-chain scenarios and use cases. Subsquid’s ability to index data across chains and across Substrate and EVM transactions can create unified visibility for developers building this new kind of multichain application.”

Subsquid CEO Dmitry Zhelezov highlighted the potential for these implementations: “Thanks to the Moonbeam and Moonriver networks, it is possible for Web3 developers to get the best of both worlds — Ethereum’s EVM composability and thriving smart contract ecosystem combined with the natively cross-chain capabilities of Substrate. We know that data only becomes truly valuable when it’s possible to join it together and aggregate it, so we believe our collaboration with Moonbeam could lead to some incredible outcomes.”

Here at Subsquid, we are very much looking forward to seeing the various new DApps and ecosystem components that will arise as a result of our solution’s Moonbeam and Moonriver implementations. This is especially true given Moonbeam’s fantastic track record of flawless EVM compatibility on its main network and on Moonriver. We will be sure to provide updates about these integrations through our official channels. We also encourage our community to review the excellent information provided on Moonbeam’s website.

About Subsquid

Subsquid is an on-chain data processing solution that enables Web3 builders to gain access to on-chain data on their own terms. Featuring multi-layer architecture and decentralised governance, this is the most developer-friendly and resource-efficient way to build, test, and deploy customised APIs for all blockchain-facing applications.

About Moonbeam

Moonbeam is an Ethereum-compatible smart contract platform on the Polkadot network that makes it easy to build natively interoperable applications. This Ethereum compatibility allows developers to deploy existing Solidity smart contracts and DApp frontends to the network with minimal changes. As a parachain on the Polkadot network, Moonbeam benefits from the shared security of the Polkadot relay chain and integrations with other chains that are connected to Polkadot.
