Hi everyone! I found that I cannot use feeAssetId for mass transfer but bockchain is support this functionality:

Hi, @egor11223!

Blockchain supports only MassTransfer transactions with feeAssetId in WAVES. So you can't specify other assets as fee here.

@msmolyakov but in blockchain we can chose feeAssetId if in asset token enabled sponsorship.

Sponsored fee is supported only for Transfer and InvokeScript transactions in blockchain, not for MassTransfer or any other types.
