Transfer ERC20

Send ERC20 tokens to another account on Loopring L2
The SDK provides the ability to transfer a supported ERC20 token to another account on Loopring Layer2.
Trade value should with decimals 
sdk.toBig(value).times("1e" + TOKEN_INFO.tokenMap.LRC.decimals)
const { exchangeInfo } = await LoopringAPI.exchangeAPI.getExchangeInfo();
const LOOPRING_EXPORTED_ACCOUNT.exchangeAddress =  exchangeInfo;
Step 1: Get account Info
1
const { accInfo } = await LoopringAPI.exchangeAPI.getAccount({
2
  owner: LOOPRING_EXPORTED_ACCOUNT.address,
3
});
4
console.log("accInfo:", accInfo);p
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
  {
3
    accountId: accInfo.accountId,
4
  },
5
  eddsaKey.sk
6
);
7
console.log("apiKey:", apiKey);
8
const { userBalances } = await LoopringAPI.userAPI.getUserBalances(
9
  { accountId: LOOPRING_EXPORTED_ACCOUNT.accountId, tokens: "" },
10
  apiKey
11
);
Step 4: Get storageId
1
const storageId = await LoopringAPI.userAPI.getNextStorageId(
2
  {
3
    accountId: accInfo.accountId,
4
    sellTokenId: TOKEN_INFO.tokenMap["LRC"].tokenId,
5
  },
6
  apiKey
7
);
8
console.log("storageId:", storageId);
Step 5: Get fee
1
const fee = await LoopringAPI.userAPI.getOffchainFeeAmt({
2
  accountId: accInfo.accountId,
3
  requestType: sdk.OffchainFeeReqType.TRANSFER,
4
}, apiKey);
5
console.log("fee:", fee);
Step 6: Transfer
1
const transferResult = await LoopringAPI.userAPI.submitInternalTransfer({
2
  request: {
3
    exchange: LOOPRING_EXPORTED_ACCOUNT.exchangeAddress,
4
    payerAddr: accInfo.owner,
5
    payerId: accInfo.accountId,
6
    payeeAddr: LOOPRING_EXPORTED_ACCOUNT.address2,
7
    payeeId: LOOPRING_EXPORTED_ACCOUNT.accountId2,
8
    storageId: storageId.offchainId,
9
    token: {
10
      tokenId: TOKEN_INFO.tokenMap.LRC.tokenId,
11
      volume: LOOPRING_EXPORTED_ACCOUNT.tradeLRCValue.toString(),
12
    },
13
    maxFee: {
14
      tokenId: TOKEN_INFO.tokenMap["LRC"].tokenId,
15
      volume: fee.fees["LRC"].fee ?? "9400000000000000000",
16
    },
17
    validUntil: LOOPRING_EXPORTED_ACCOUNT.validUntil,
18
  },
19
  web3,
20
  chainId: sdk.ChainId.GOERLI,
21
  walletType: sdk.ConnectorNames.Trezor,
22
  eddsaKey: eddsaKey.sk,
23
  apiKey: apiKey,
24
});
25
console.log("transferResult:", transferResult);
