Goldsky provides a completely backwards-compatible subgraph indexing solution. The core of the indexing uses exactly the same WASM processing layer, but in addition, Goldsky offers:
a rewritten RPC layer, autoscaling query layer, and storage optimizations to improve reliability (99.9%+ uptime) and performance (up to 6x faster)
webhooks support out-the-box to enable notifications, messaging, and other push-based use cases
support for custom EVM chains so you can index your own rollup or private blockchain seamlessly
