Run (Events Only)

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

Sepolia:

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

Amoy:

cd /Users/kd/substreams/xarb-substreams/xarb-substreams-spoke
substreams run substreams.yaml map_events_only --network polygon-amoy

Optional Run (Events + Calls)

Use map_events_calls only when you need call-level output.

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

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

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.
