Getting block timestamp in contract events without calling the getBlock() promise

👋 love the library! is there any way to get the timestamp of the block in the contract.on event feed without having to use the async getBlock() function? Or is the block already cached and getBlock() essentially returns right away?

i.e. something like:

contract.on(filter, async (event) => {
  const ts = event.blockTimestamp;
});

For context, I’m loading a snapshot from a contract function which returns the block timestamp of the snapshot (instead of the block number), and trying to diff the event blocks with the snapshot block timestamp (to discard any events from before the snapshot).

The logs RPC on a eth node (eth_getLogs) does not include a timestamp. So just with an eth node endpoint, AFAIK you will have to do the eth_getBlockByNumber RPC (used in provider.getBlock). I really wish if timestamp would be there in logs since it’s much wanted, but maybe it’s not due to performance reasons.

If you frequently need to fetch the logs + timestamp, you may consider using TheGraph. Here’s an example of getting timestamp on an event.

yes, forgot to respond, thanks! ended up working around it.
