Does anyone know how to define a custom fee (BATCH transactions)

[cryptoworld99]

Hi,


I would like to batch bitcoin transactions, does anyone know how to define a custom fee using the sendmany RPC function.

Thank you in advance!

I don't see any parameter to add custom fees using RPC sendmany from here https://chainquery.com/bitcoin-cli/sendmany

However, you can change your fee by using the command below you can edit the 0.0001 to any fee you want.

Sample

Code:

settxfee 0.0001

Source of idea: https://bitcointalk.org/index.php?topic=1006929.0

Use that command first before you make a batch transactions.

Have you tried this?

If you are using version 0.21.0 or higher you can use the fee_rate argument (as suggested by TryNinja) and set the fee_rate in sat/vByte.
This feature was introduced in V 0.21.0. If you are using an older version, core will calculate the feerate depending on the number of blocks you're willing to wait before your transaction confirms (conf_target) and the priority (estimate_mode).
