Any reason why we need duplicated events for different chains? AFAICT only on Arbitrum the respective event is different. But can't we just reuse the Deposit event signature for every other chain? This would also decrease the number of else if cases in the code

I don't think we need a different ABI file for every chain if they are the same, no?

Unfortunately the ABIs are not the same and I didn't want to spend time putting together a common ABI file

Hmm okay, got you.. Maybe we could also just reduce the ABI to the minimal interfaces with need / care about, i.e.
{
"anonymous": false,
"inputs": [
{
"indexed": true,
"name": "dst",
"type": "address"
},
{
"indexed": false,
"name": "wad",
"type": "uint256"
}
],
"name": "Deposit",
"type": "event"
},

Don't we need to also add the check
typedEvent.args.from === ZERO_ADDRESS
? So that we don't consider a normal WETH transfer but rather a "deposit", i.e. mint.

spokePoolAddresses.includes(typedEvent.args.to) checks if the recipient of WETH is the SpokePool contract. Do you think it's necessary to also check from address? I cannot see a case when someone sends WETH intentionally to the SpokePool followed by a deposit

Yea, you are right. Should be very unlikely
