Code use JS:

async function testgetSign() {
    let domain = {
        name: "Galaxy",
        version: "1.0.0",
        chainId: "97",//Come back and hardcode the ID later
        verifyingContract: "0xE66F7BCf50DB58e41eC57917278E7eb67c754279"
    };

    let types = {
        NFT: [
            { name: "cid", type: "uint256" },
            { name: "starNFT", type: "address" },
            { name: "dummyId", type: "uint256" },
            { name: "powah", type: "uint256" },
            { name: "account", type: "address" },
        ]
    };

    let value = {
        cid: "2",
        starNFT: "0x3C0Ef7DA64d37275eB42E560615d484eA293F5f6",
        dummyId: "1",
        powah: "1",
        account: "0xA128b0c7E06f869AF6D81a46851CEcBA40DCE8f2",
    }


    prvtKey = "xxx"

    const wallet = new ethers.Wallet(prvtKey);
    const signature = await wallet.signTypedData(domain, types, value);
    console.log(signature);
}
testgetSign()

galaxy_signer: 0xE66F7BCf50DB58e41eC57917278E7eb67c754279
