const ethers = require('ethers');
const NODE_URL = "CHAINSTACK_NODE_URL";
const provider = new ethers.JsonRpcProvider(NODE_URL);

// pathUSD token address
const PATHUSD = "0x20c0000000000000000000000000000000000000";

const getStorage = async () => {
    // Slot 0 typically contains the total supply in ERC20 contracts
    const value = await provider.getStorage(PATHUSD, 0);
    console.log(`Storage slot 0: ${value}`);

    // Read a specific slot
    const slot5 = await provider.send("eth_getStorageAt", [
      PATHUSD,
      "0x5",
      "latest"
    ]);
    console.log(`Storage slot 5: ${slot5}`);
