ArrowSquid for Substrate announcement #293
Description
We are proud to release ArrowSquid in public beta. It is by far the most advanced indexing toolkit for Substrate chains, which literally gives superpowers:
- Blazing fast indexing of traces and storage diffs w/o an archive node. The implications are endless -- validator/staking rewards, XCM transfers, frozen balances -- everything that required tedious and costly RPC call can now be efficiently queried, filtered and aggregated in batches
- Support for unfinalized blocks with automated rollback handling. True real-time experience for dApps is now unlocked
- A powerful type system and a fully reworked typegen. Now developers can extract only the necessary pieces of data from events and transactions with a surgical precision. One can mix generated and manually defined types! The flexibility allows to make forward- and backward- compatible squids, handling runtime upgrades like a breeze.
- Easily access the full trace of calls or the wrapping extrinsic data from an event and wise versa -- thanks to the new design of the indexing context interface
- Native support for indexing internal calls -- no more manual onwrapping of batch, proxy or sudo extrinsics
- Support for RPC-only data sources. Squids now can work even without a Subsquid Archive! Super easy setup for indexing local and dev chains.
- Blazing fast SKALE codec and a metadata service. Simply 10x faster decoding then polkadot.js
- Lots of quality-of-life improvements like native ss58 address handling
