A Batch Request for querying Coin and Tokens

[soharang]

Hi,

Is there any way to get coin and token balances in the same account with one query?

For example, I have ETH account and in there, three ERC20 Tokens A,B,C.
So far, to get all balances of them, I have to do 4 queries - one for ETH, and three for each token.

As far as I know, I can use BatchRequest for multiple request but I have no idea how to apply ERC20 balance query in it.

Thanks in advance.

You can use this class - https://github.com/web3j/web3j/blob/master/core/src/main/java/org/web3j/protocol/core/BatchRequest.java
Create a new BatchRequest, add requests to this and lastly use send function to send the batchRequest.
