createContractEventFilter returns no events without setting a fromBlock

[DannyDelott]

Is there an existing issue for this?

• I have searched the existing issues

Package Version

1.4.2

Current Behavior

The fromBlock arg is typed as optional in createContractFilter, but you won't get any events back without it.

Expected Behavior

If you don't pass a fromBlock, it should default to "earliest". At a minimum, this keeps the mental model the same between viem and ethers. (see: https://docs.ethers.org/v6/api/contract/#BaseContract-queryFilter)

Steps To Reproduce

See repro example

Anything else?

Isn’t this expected? I’d expect for it to create a filter at the latest block.

Changing this would be a breaking change, and I would rather have the behaviour in sync with the node.
