How to get supply data

To retrieve specific Jetton data, use Jetton master contract’s get_jetton_data() method.

This method returns the following data:

Name	Type	Description
total_supply	VarUInteger 16	the total number of issued jettons measured in indivisible units
mintable	Bool	Indicates whether new jettons can be minted (-1 for true, 0 for false)
admin_address	Address	admin’s address
jetton_content	Cell	data formatted according to TEP-64
jetton_wallet_code	Cell	a code of the corresponding Jetton wallet

You can call the get_jetton_data() method from your favorite IDE:

import { TonClient, Address } from "@ton/ton"

async function main() {
    const client = new TonClient({
    endpoint: 'https://toncenter.com/api/v2/jsonRPC',
    });

    const JettonMasterAddress = Address
    .parse('0:b113a994b5024a16719f69139328eb759596c38a25f59028b146fecdc3621dfe');

    const data = await client.runMethod(JettonMasterAddress,
    'get_jetton_data');

    const Stack = data.stack;

    console.log(Stack.readNumber()); // Total supply

    console.log(Stack.readNumber()); // mintable

    console.log(Stack.readAddress().toString()); // Admin address

    console.log(Stack.readCell()); // jetton_content

    console.log(Stack.readCell()) // jetton_wallet_code
}

void main();

Or call it through a web service, such as Tonviewer:

Finally, you can get this information using the API.
