substrate node-template how to add `total_insuance` with some accounts initial supply

Question

I am using susbstrate node-template, I am trying to create my own native token d-coin with xxxxx amount of total supply, I am using auro consensus, I was able to add some properties to genesis state, below is code, which is working fine, but I am looking set total supply and transaction fees.

pub fn properties() -> Properties {
    let mut properties = Properties::new();
    properties.insert("ss58Format".into(), x.into());
    properties.insert("tokenSymbol".into(), "D".into());
    properties.insert("tokenDecimals".into(), "xx".into());
    properties.insert("totalSupply".into(), "xxxxxxxxx".into());
    properties
}

Answer 1

Considering that you are using the pallet_balances your answer is given here. Have a look at the seminar: 6 ways to launch a token it provides information you are probably interested in.

As for transaction fees you should look into pallet_transaction_payment, see here how the default is implemented in the node-template. The seminar provides information about this as well.

Answer 2

As my understanding, you can't configure totalSupply Properties in Substrate.

Substrate has no limit on the total supply of the native token.

It would be helpful if someone could confirm whether I am correct or not.
