    const price = await checkPrice.getPrice(token);
    console.log(price);
}

Get V2 Pool

async function getV2Pool(token: string) {
    const pool = await checkPrice.getV2Pool(token);
    console.log(pool);
}

Get V3 Pool

async function getV3Pool(token: string) {
    const pool = await checkPrice.getV3Pool(token);
    console.log(pool);

async function getEthUsdPrice() {
    const price = await checkPrice.getEthUsdPrice();
    console.log(price);
}
