[TASK] Process DKG/Substrate extrinsic calls through Tx queue

[shekohex]

Overview

DKG should make use of the Substrate Transaction Queue instead of in-place sending transactions.

Task Checklist

• Create transactions in-place and encode them.
• Make use of the Substrate tx queue.
• Process all extrinsic calls made to DKG and substrate through the tx queue like from here

Is there an example somewhere how this tx queue should be used?

Here is an example of using the transaction queue:
