How to set fee in raw bitcoin transaction using btcutil

0 votes

I have set the fee to 0.0000016 bitcoin/kilobyte and then did the following:-

  1. ListUnspent

  2. SetTxFee

  3. CreateRawTransaction

  4. SignRawTransaction

  5. SendRawTransaction

But while trying to send the transaction, this is what I get:

-26: 256: absurdly-high-fee

Is there any other way to set the fee using this library?


ThreadRPCServer method=listunspent 
ThreadRPCServer method=settxfee 
ThreadRPCServer method=createrawtransaction 
ThreadRPCServer method=signrawtransaction 
ThreadRPCServer method=sendrawtransaction


amounts := map[btcutil.Address]btcutil.Amount{ destAddress: destAmount, }

It seems like it tries to send the whole sum of the transaction, not the amount I want it to send. If the transaction into A is 1 BTC and I want to send 0.3 BTC to another address, how to achieve this when setting amounts?

To answer your question, the settxfee is not used for the createrawtransaction command. However, if you have one input with 1 BTC and you send 0.9 BTC, the remaining amount is the transaction fee and if you don't want to set a transaction fee for 0.1 BTC you could send 0.09 to change address and leave that 0.01 and it's your transaction fee.
