how do you check the number off transaction confirmations of an ethereum transaction using web3j?

by yemista   Last Updated January 14, 2018 06:28 AM

I looked through the documentation but there doesnt seem to be mention of this. I tried to debug it and look at the status of the transaction receipt but it is always null. Is there any way to do this?

Generally, what people mean when they count the number of confirmations is how many blocks there have been since the one the given transaction was in.

So all you need to do is find out the current block number (web3.eth.getBlockNumber(function (err, number) { ... });) and then subtract the block number from your transaction receipt.
