Size limit on metadata

Question

Hi,

Is there a size limit on the metadata which we can pass to sendwithmetadata command? Saw one blockchain param - max-std-op-return-size. Is this how you control it and what is the max limit for this? 

Answer 1

We've tested it successfully with up to 8 MB of metadata per transaction. But to allow that you need to increase these blockchain parameters:

maximum-block-size

max-std-td-size

max-std-op-return-size

Also note that if you do a lot of transactions of this size, you will come up against the limitations of the current wallet.
