One approach VulcanizeDB takes to caching and indexing smart contracts is to watch contract events emitted in receipt logs.
With a light synced vDB we can watch events by iterating over headers retrieved from the synced `headers` table and using these headers to
With a header synced vDB we can watch events by iterating over headers retrieved from the synced `headers` table and using these headers to
fetch and verify relevant event logs from a full Ethereum node, keeping track of which headers we have checked for which events
with our `checked_headers` table.
## Assumptions
This approach assumes you are running a vDB light sync which is itself run against a light Ethereum node,
This approach assumes you are running a vDB header sync which is run against a light Ethereum node;
this approach also assumes there is a full node available.
Looking forward, we will be building fetchers that enable sourcing data from IPFS instead of an ETH node.

### [Event Watcher (light sync)](../staging/libraries/shared/watcher/event_watcher.go)
### [Event Watcher (header sync)](../staging/libraries/shared/watcher/event_watcher.go)
The event watcher is responsible for continuously fetching and delegating chunks of logs and their associated header to the appropriate transformers.
