README

Substreams

Substreams is an indexer for onchain events when subgraphs aren't available.

https://docs.substreams.dev

Deploy subgraph

Each chain has its own configuration file. See the justfile for deployment commands.

Example: Sepolia

  1. Copy an existing configuration file and rename it to substreams-sepolia.yaml
  2. Update the package name field in the config to name: sepolia-orderbook
  3. Update the starting block initialBlock: 10108380
  4. Update the parameter field to the appropriate chain id to map_evm_events: "11155111"
  5. Update the neywork field to network: sepolia
  6. Build and publish the spkg file with just build-and-publish-evm sepolia
  7. Deploy an indexing service using the docker image specified in the justfile
  8. Set PACKAGE env variable to sepolia-orderbook-v0.1.1.spkg
  9. Test with just debug-gui sepolia 10108380 (next 10 block should have events)
