README

xarb-substreams-hub

Substreams package for xArb hub-side events on Base Sepolia (84532).

Directory

xarb-substreams-hub/
  substreams.yaml
  .env.example
  src/
  build.rs

Build

cd /Users/kd/substreams/xarb-substreams/xarb-substreams-hub
cp -n .env.example .env
substreams build

Run (Events Only)

map_events_only is the default output module used by current propagator flow.

cd /Users/kd/substreams/xarb-substreams/xarb-substreams-hub
substreams run substreams.yaml map_events_only

Optional Run (Events + Calls)

Use map_events_calls only when you need call-level output.

cd /Users/kd/substreams/xarb-substreams/xarb-substreams-hub
set -a
source .env
set +a

substreams run substreams.yaml map_events_calls \
  -p "map_calls=${XARB_HUB_TRACKED_CONTRACTS}"

Tracked Address Sync

When contracts are re-deployed, run the monorepo sync script:

cd /Users/kd/substreams/xarb-substreams
./scripts/redeploy_and_sync_contracts.sh

It updates .env, deployment JSONs, and substreams.yaml filters to latest addresses.

Notes

  • substreams.yaml has static blockFilter values for call indexing modules.
  • If manual edits are made to tracked addresses, rebuild with substreams build.
