Deposit NFT

Definition: Move user L1 NFT assets to Loopring L2

All Deposit Method, User should have enough ETH pay for the Ethereum Gas (Loopring have no charge, no fee for Deposit).

Step 1. getNFTBalance & getEthBalances

const {ethBalance} = await LoopringAPI.exchangeAPI.getEthBalances({
  owner: LOOPRING_EXPORTED_ACCOUNT.address,
});
const nftBalance = await LoopringAPI.nftAPI.getNFTBalance({
  web3,
  account: LOOPRING_EXPORTED_ACCOUNT.address,
  tokenAddress: LOOPRING_EXPORTED_ACCOUNT.nftTokenAddress,
  nftId: LOOPRING_EXPORTED_ACCOUNT.nftId,
  nftType: sdk.NFTType.ERC1155,
});

Step 2. isApprovedForAll

 const isApprovedForAll = await LoopringAPI.nftAPI.isApprovedForAll({
  web3,
  from: LOOPRING_EXPORTED_ACCOUNT.address,
  exchangeAddress: LOOPRING_EXPORTED_ACCOUNT.exchangeAddress,
  nftType: sdk.NFTType.ERC1155, // todo： sdk.NFTType.ERC721
  tokenAddress: LOOPRING_EXPORTED_ACCOUNT.nftTokenAddress,
});
console.log(`check is approveNFT`, isApprovedForAll);

Step 3. approveNFT All

  if (!isApprovedForAll) {
  const nonce = await sdk.getNonce(
    web3,
    LOOPRING_EXPORTED_ACCOUNT.address
  );
  const approveNFT = await LoopringAPI.nftAPI.approveNFT({
    web3,
    from: LOOPRING_EXPORTED_ACCOUNT.address,
    depositAddress: LOOPRING_EXPORTED_ACCOUNT.depositAddress,
    tokenAddress: LOOPRING_EXPORTED_ACCOUNT.nftTokenAddress,
    nftType: sdk.NFTType.ERC1155, // todo： sdk.NFTType.ERC721
    gasPrice: LOOPRING_EXPORTED_ACCOUNT.gasPrice,
    gasLimit: LOOPRING_EXPORTED_ACCOUNT.gasLimit,
    chainId: sdk.ChainId.GOERLI,
    nonce,
    sendByMetaMask: true,
  });
  console.log(`nonce: ${nonce} approveNFT: ${approveNFT?.result}`);
}

Step 3. nonce

 const nonce = await sdk.getNonce(web3, LOOPRING_EXPORTED_ACCOUNT.address);

console.log(
  `deposit: NFT, gasPrice: ${LOOPRING_EXPORTED_ACCOUNT.gasPrice}, `
);

Step 4. depositNFT

  const response = await LoopringAPI.nftAPI.depositNFT({
  web3,
  from: LOOPRING_EXPORTED_ACCOUNT.address,
  exchangeAddress: LOOPRING_EXPORTED_ACCOUNT.exchangeAddress,
  nftType: sdk.NFTType.ERC1155,   // todo： sdk.NFTType.ERC721
  tokenAddress: LOOPRING_EXPORTED_ACCOUNT.nftTokenAddress,
  nftId: LOOPRING_EXPORTED_ACCOUNT.nftId,
  amount: 2,   // todo：when sdk.NFTType.ERC721  amount: 1,
  gasPrice: LOOPRING_EXPORTED_ACCOUNT.gasPrice,
  gasLimit: LOOPRING_EXPORTED_ACCOUNT.gasLimit + 100000,
  chainId: sdk.ChainId.GOERLI,
  nonce,
  sendByMetaMask: true,
});
console.log(`nonce: ${nonce} deposit NFT ERC1155: `, response);
