SubQuery Extends Indexing To Acala
SubQuery Extends Indexing to Acala’s New EVM+, Offering Universal EVM Support within Polkadot
Firstly, SubQuery Extends Indexing To Acala. SubQuery Polkadot’s leading data indexer, the first data indexer providing full smart contract indexing support for Acala’s new EVM+. This joins existing EVM support for Parity’s Frontier EVM implementation and SubQuery provides support for all EVMs in the Polkadot.
Acala’s EVM+ is Acala’s implementation of the Ethereum Virtual machine, currently the world’s most popular smart contract platform. It stems from a desire to not just build the fastest, cheapest Ethereum sandbox. A lightweight solution that maximises interoperability between events outside the EVM and within. It also enables developers to build dApps on Acala with existing tooling support from Ethereum such as Remix and Waffle and pay for gas in any supported tokens (automatically using Acala’s DEX).
They’ve been working closely with the team at Acala for some time to extend SubQuery to natively support EVM+. The new EVM+ implementation offers a simple way to filter and index both EVM+ and Substrate activity on Acala. You can index EVM+ Calls or events, and filter these based on call function signatures, event log topics, and/or smart contract addresses.
Excellent Documentation
We’ve updated the excellent documentation to include detailed information about the support for Acala’s EVM+. In addition, you can try out the example acala-evm-starter project on GitHub and extend it to index your own creation. The sample project currently indexes all transfer and approval events from the ACA token. Can easily be used as a starting point for all new SubQuery Projects.
One interesting aspect of our integration with Acala’s EVM+ is that SubQuery itself will be migrating our own smart contract code across in preparation for the SubQuery Network launching on Acala. Our Network team will be one of the first users of our new EVM+ support and will benefit from the ease it brings, just like other teams building their own dApps on Acala.
As always, any SubQuery project built using Acala’s EVM+ support can be hosted on SubQuery’s managed service — a free and industry leading hosting solution for all customers that is serving hundreds of millions of daily requests to the biggest projects in Polkadot. Additionally, if you’re ready to build the next big dApp, take a look at the Acala sponsored bounties on SubQuery’s Grants programme and apply today.
About Acala
Acala is a decentralized finance network powering the aUSD ecosystem. The core product, aUSD, a decentralized, multi-collateral, crypto-backed stablecoin serving as the native stablecoin of the Polkadot ecosystem. Acala’s Ethereum-compatible blockchain has built-in DeFi protocols for application developers to leverage. Including, trustless staking derivative (liquid DOT — LDOT), a decentralized exchange, and the EVM+, a hybrid EVM offering fully Ethereum-compatible development environment plus full compatibility with Substrate.
About SubQuery Network
SubQuery is a blockchain developer toolkit enabling others to build Web3 applications of the future. A SubQuery project is a complete API to organise and query data from layer-1 chains. Currently servicing Polkadot, Substrate and Avalanche projects. This data-as-a-service allows developers to focus on their core use case and front-end, without needing to waste time on building a custom backend for data processing. The SubQuery Network proposes to enable this same scalable and reliable solution, but in a completely decentralised way.
