Indexer Auto-generation
https://github.com/metacontract/indexer

This Rust-based embedded indexer reads your metacontract schema and aggregate relevant data to anywhere you want.

You don't need to write Subgraph and it'll scale as long as you need more aggressive decentralization.

As this indexer is read-only system and lower burden to maintain by small team, it can be run on with CloudFlare D1 instance or your UI hosting server.
