I'd like to get pending transactions information without running my own node. Is there any way to do that?

Something like this would work too, but they only seem to provide a fraction of the pending transactions they see.

  • Are you looking for that: etherscan.io/txsPending ? Nov 12, 2017 at 9:37
  • That would be perfect if I could access it through their API. Nov 12, 2017 at 13:13
  • I just saw that your post title includes web3. You cannot use web3 without having a node running. Nov 13, 2017 at 1:04
  • I've been using web3 with a third party (infura) node, as per the title. Most functionalities work, but not the txpool features, as it returns: "HTTPError: 405 Client Error: Method Not Allowed for url: mainnet.infura.io/<ClientID>" Nov 13, 2017 at 5:05
  • Maybe you should ask the Infura community. Nov 13, 2017 at 5:11

The standard Infura endpoint does not allow you to do that. I would suggest to use Chainstack, you can create a free node and allows you to do it. I have a repo showing exactly that in python using web3.py Find it here

This is the main code to retrieve the hash of pending transactions in web3.py

# retrive pending transactions hash
pending_tx_filter = web3.eth.filter('pending')
pending_tx = pending_tx_filter.get_new_entries()     # this is a list object

# loop through the list of transcations and displays the tx hash
for hash in pending_tx:
    print('Hash of a Pending Transaction:' , web3.toHex(hash))

You can use this tool to get a visualisation of pending transaction. There is not API however.

I've been creating "work-around" for this, but in the meanwhile I saw this - https://www.shawntabrizi.com/ethereum/using-web3-js-1-0-subscribe-and-infura-websockets-to-visualize-ethereum-transactions/ ( haven't tried it, yet ). Tell me if it is of any help :)
