Network fees

Network fees are amounts that spenders may include in their on-chain transaction in order to have it included in a block.

There are three network fee levels available for coin withdrawal transactions.

network_fee_level	block	time
slow	7	~1 hour
average	3	~30 minutes
fast	1	~10 minutes

It is a very dynamic thing, therefore each level changes its value every minute in such a way as to guarantee that the transaction will be included in a specific block within a given time frame.

Use this API endpoint to get the list of network fee levels.
