indexing: self-hosted subgraph (Graph Node) compatibility plan #236
Description
Goal
Provide a developer path to run a subgraph-like indexer against Catalyst (self-hosted first), with a clear migration path to hosted providers later.
Scope
- Choose approach:
- Graph Node compatibility layer (Ethereum-like JSON-RPC + logs/events), or
- Catalyst-native indexer + GraphQL API schema + mappings
- Minimal reference deployment (Docker compose): node + indexer + DB + GraphQL endpoint
- Documentation for developers to run it on a server
Acceptance criteria
- A developer can self-host an indexing stack and query token transfers / contract events
- Clear documentation of what parts of Ethereum/TheGraph are supported and what is not
- Plan to reach hosted providers (TheGraph/Goldsky) over time
