Web3 how to listen to contract events on pending transactions?

Question

I'm currently trying to listen to contract events from a contract address but on pending transactions. But I only got confirmed transaction on the instead of pending. Here my code

let subscription = web3.eth.subscribe("logs", {
  fromBlock: "pending",
  address: ["0x0eD7e52944161450477ee417DE9Cd3a859b14fD0"],
  topics: [], 
});

subscription.on("data", async (event) => {
  const tx = await web3.eth.getTransaction(event.transactionHash);
  console.log("tx", tx); //this is confirmed transaction because it has block number in it
});

How to listen events only for pending transactions ?

Answer 1

subscribe for events for pending transactions not possible. event executed only when call function in smartcontract. so, if transaction have status pending - any events not executed.
