MetaMask Developer에서 API key 하나 생성하고

const { ethers } = require("ethers");

async function scanSlots(provider, contractAddress, startSlot, endSlot) {
    for (let i = startSlot; i <= endSlot; i++) {
        const slotValue = await provider.getStorageAt(contractAddress, i);
        console.log(`Slot ${i}: ${slotValue}`);
    }
}

async function main() {
    const provider = new ethers.providers.JsonRpcProvider("https://sepolia.infura.io/v3/dd96abf2cf5c4458a9988bb4d7e17bda");
    const contractAddress = "0xc48bdba1481c391cf67249818d2e972f737976d8";

    console.log("Scanning slots ");
    await scanSlots(provider, contractAddress, 0, 10); 
}

main().catch(console.error);
