How stream pending transaction

[aliriohg]

Hey,

I'm trying to stream all transactions by address, in the moment I use this

provider.on('pending', (tx) => {
provider.getTransaction(tx).then(function(transaction) {
if (transaction != null) {
if (transaction.from.toLowerCase() == wallet_to_tracker.toLowerCase()) {
console.log('pending tx from wallet', transaction);
}
}
});
});

some filter can do this
since I analyze all transactions

Bonus Question =D
I would like to have all the information of the transaction before for example
provider.on('pending', (tx) => {
console.log('transaction: ',tx);
if (tx.from.toLowerCase() == wallet_to_tracker.toLowerCase()) {
console.log('pending tx from wallet', transaction);
}
});
});

is this possible or necessary use provider.getTransaction(tx)
because, I would like to know the transaction data and all the information before it is approved or failed

Thanks Cracks

The standard API only gives you a list of pending transaction hashes.

There are, however, some non-standard APIs available in some backends which provide you the entire transaction info as well as filter pending transaction from specific addresses and more filtering options. I'm not sure if Infura/Alchemy/QuickNode allow you to access those non-standard APIs though.

thanks zemse, i check the response provider.getTransaction(tx) and this return the transaction without resolve because return without block and etc thanks

Hello @zemse, I have a question
I use wss: //bsc-ws-node.nariox.org: 443 but lately I have trouble connecting with it
I have been looking at providers for the pending tx but the tx I need do not appear and with nariox yes, any idea of providers that can offer me that quality

Thank you

I'm not much familiar with bsc provider services. Though I could see some rpcs in their docs, unless you have already know that, you can find some links to 3rd party providers at the bottom of the page.
