Envio
Envio HyperIndex subgraph compatibility mode (~200x faster than Graph Node) and v3.5-3.9 multichain featuresverified
Run unmodified subgraph projects on HyperIndex via `pnpx envio@3.7.0-subgraph dev`. v3.5-3.9 added per-chain isolation, unlimited factory addresses, @crossChain, ClickHouse skipping indexes, 35 extra tx/block fields, per-handler field selection, Prometheus stall metrics. June update claimed 2.5x faster / 2x cheaper indexing (v3.1/3.2).
Do: Test one existing subgraph on the subgraph-compat build; upgrade HyperIndex to 3.9. docs.envio.dev/blog/developer-update-august-2026 docs.envio.dev/blog
