Modify number of confirmations

Question

By default there are 24 confirmations but I am running a testnet with just 3 miners and I would like to change this number bucause it makes not sense to have 24. I have been checking transactionConfirmationBlocks on the following way:

const options = {
   transactionConfirmationBlocks: 3
}

var web3 = new Web3(new Web3.providers.WebsocketProvider(provider_string, options));

I am not getting errors, but when I make a transaction it is still making 24 confirmations. if I check the number of confirmations (web3.eth.transactionConfirmationBlocks) is still 24. What is the right way to set the number of confirmations?

You need to pass the options parameter to Web3, not to WebsocketProvider, like this:

const options = {
   transactionConfirmationBlocks: 3
}

const web3 = new Web3(
  new Web3.providers.WebsocketProvider(provider_string),
  null,
  options
);

According to the docs it can also be set like this:

web3.transactionConfirmationBlocks
web3.eth.transactionConfirmationBlocks
web3.shh.transactionConfirmationBlocks

You tryed this?

const Web3 = require('web3')

const options = {
    transactionConfirmationBlocks: 24,
}

const web3 = new Web3('http://localhost:8545', null, options);
