Definition: Use this method to understand how to match an NFT maker order with an NFT taker order.

Trade NFT

Private or third party accounts can sign and approve this order
// Step 1. getAccount
const accInfoC = (
await LoopringAPI.exchangeAPI.getAccount({
owner: LOOPRING_EXPORTED_ACCOUNT.address,

// Step 1. eddsaKeyC
const eddsaKeyC = await signatureKeyPairMock(accInfoC);
// Step 3. apiKey
const apiKeyC = (
await LoopringAPI.userAPI.getUserApiKey(
{
accountId: accInfoC.accountId,

// NFT Trade
