Beta support for Arbitrum is here!

After much anticipation from the community, we are excited to finally announce Subsquid’s beta support for Arbitrum, our first Ethereum L2. dApp builders and data analysts can now get rapid access to Arbitrum data using the open-source squid SDK. They may also host their indexing projects for free in Subsquid’s managed service, Aquarium.

Why build a squid indexer on Arbitrum?
> TypeScript-based SDK for building fully-customizable GraphQL APIs and ETLs
> Support for 70+ EVM, Substrate, and EVM chains
> Indexing at up to 50,000 blocks per second
> Free hosted service while in beta
> Dedicated support team
> Open-source project

For questions relating to the technology or to potential partnerships, builders are invited to join the official Subsquid community on Discord.

Quickstart Guide for EVM Chains

This demo squid outputs transactions to the “black hole” address 

It is intended to be a starter project for building a custom squid that
indexes the EVM logs and transaction data of EVM chains.

Before getting started, come up with an original name for your squid,
then generate your demo with the following commands:

> sqd init my-awesome-squid — template evm
> cd my-awesome-squid
> npm ci
> npm run build
> make up
> make process

Don’t forget to install squid CLI!

> brew tap subsquid/cli
> brew install sqd
> npm i -g @subsquid/cli@latest
Check the version:
> sqd — version

There are many squid templates available. Explore them all by entering:

> sqd init — help

Full quickstart guide available here.
