// Step 1. getAccount
const accInfoC = (
  await LoopringAPI.exchangeAPI.getAccount({
    owner: LOOPRING_EXPORTED_ACCOUNT.address,
  })
).accInfo;

// Step 2. eddsaKeyC
const eddsaKeyC = await signatureKeyPairMock(accInfoC);

// Step 3. apiKey
const apiKeyC = (
  await LoopringAPI.userAPI.getUserApiKey(
    {
      accountId: accInfoC.accountId,
    },
    eddsaKeyC.sk
  )
).apiKey;
//  NFT Trade
const response = await LoopringAPI.userAPI.submitNFTTrade({
  request: {
    maker: {
      ...mockData.makerOrder,
      eddsaSignature: mockData.makerOrderEddsaSignature,
    },
    makerFeeBips: 1000,
    taker: {
