listen multiple events from same smart contract

[Anup9444]

how can we listen to two different events of same smartcontract at once ?
something like this
`
const withdrawEvent = instantContract.filters.InstantWithdraw(address);
const TransferEvent = instantContract.filters.Transfer(address);

   const withdrawTx = await instantContract.queryFilter(
      [withdrawEvent,TransferEvent]
      from,
      to
    );

`

That isn’t supported in v5, you will need to either subscribe to both events independently, or use provider.on and use the interface.parseLog.

It works fine in v6 though. ;)

Can you plz show us example how we can ?
Both case with subscribing both events and with provider.on

const filter1 = await myContract.filters.Event1().getTopicFilter()
const filter2 = await myContract.filters.Event2().getTopicFilter()

const topicFilter = [
    filter1.concat(filter2)
] as TopicFilter

await myContract.queryFilter(topicFilter, blockStart, blockEnd)
    .then(async (events: any) => {
        // Do something
    })

More info about the TopicFilter type in the docs : https://docs.ethers.org/v6/api/providers/#TopicFilter
