Trade value should with decimals 
sdk.toBig(value).times("1e" + TOKEN_INFO.tokenMap.LRC.decimals)
Step 1: GetAccount
1
const {accInfo} = await LoopringAPI.exchangeAPI.getAccount({
2
  owner: LOOPRING_EXPORTED_ACCOUNT.address,
3
});
4
console.log("accInfo:", accInfo);
Step 2: Get eddsaKey
1
const eddsaKey = await signatureKeyPairMock(accInfo);
2
console.log("eddsaKey:", eddsaKey.sk);
Step 3: Get apiKey
1
const {apiKey} = await LoopringAPI.userAPI.getUserApiKey({
2
    accountId: accInfo.accountId,
3
  },
4
  eddsaKey.sk
5
);
6
console.log("apiKey:", apiKey);
Step 4: Get storageId
1
const storageId = await LoopringAPI.userAPI.getNextStorageId({
2
    accountId: accInfo.accountId,
3
    sellTokenId: TOKEN_INFO.tokenMap["LRC"].tokenId,
4
  },
5
  apiKey
6
);
7
console.log("storageId:", storageId);
Step 5: Get fee
1
const fee = await LoopringAPI.userAPI.getOffchainFeeAmt({
2
    accountId: accInfo.accountId,
3
    requestType: sdk.OffchainFeeReqType.OFFCHAIN_WITHDRAWAL,
4
    tokenSymbol: TOKEN_INFO.tokenMap["LRC"].symbol,
5
  },
6
  apiKey
7
);
8
console.log("fee:", fee);
Step 6: Withdraw
1
const response = await LoopringAPI.userAPI.submitOffchainWithdraw({
2
  request: {
3
    exchange: LOOPRING_EXPORTED_ACCOUNT.exchangeAddress,
4
    accountId: LOOPRING_EXPORTED_ACCOUNT.accountId,
5
    counterFactualInfo: undefined,
6
    fastWithdrawalMode: false,
7
    hashApproved: "",
8
    maxFee: {
9
      tokenId: TOKEN_INFO.tokenMap["LRC"].tokenId,
10
      volume: fee.fees["LRC"].fee ?? "9400000000000000000",
11
    },
12
    minGas: 0,
13
    owner: LOOPRING_EXPORTED_ACCOUNT.address,
14
    to: LOOPRING_EXPORTED_ACCOUNT.address,
15
    storageId: 0,
16
    token: {
17
      tokenId: TOKEN_INFO.tokenMap.LRC.tokenId,
18
      volume: LOOPRING_EXPORTED_ACCOUNT.tradeLRCValue.toString(),
19
    },
20
    validUntil: 0,
21
  },
22
  web3,
23
  chainId: sdk.ChainId.GOERLI,
24
  walletType: sdk.ConnectorNames.MetaMask,

  apiKey,
