Sending BCH: Transaction error -26: tx-size (code 64) - Code: 400


In the last few days I wanted to transfer Bitcoin Cash, however I get the following error:

«Trasaction error
-26: tx-size (code 64) - Code: 400»

What does this message mean, what am I doing wrong?

Help me, please.

Hi @Alan47,

Every time I want to transfer BCH from TrustWallet to my Binance wallet I can’t, I get the error I attached in this post.

I have on my Aplee 14 OS version installed TrustWallet version 6.1.

My BCH address is as follows:


Note: I do not have the Hash of the transaction. I have not been able to complete the transaction.

Thank you in advance!

Hello @javier_fr this is due to dust error. Read more: Unable to Send due to Dust Error


Thank you very much for the information. I guess one way to avoid the powder error is to inject more BCH to my wallet and then try to transfer a new amount higher than I wanted to send.

I will read the content you have passed me to proceed correctly in solving this problem.
