Is your feature request related to a problem? Please describe.

Here are two batch transactions executed by a proxy account. Both batch calls contain the same transactions: one 'remove_stake' and one 'add_stake'. The price changed from 0.000124681 TAO on September 23, 2024, to 0.001373038 TAO on December 4, 2024. Below are the details of the transactions. Note that adding an extra transaction in the batch call incurs additional costs.

Describe the solution you'd like

Restore batch tx prices to normal levels compared to regular transactions. It's better for the network too.

Hey @camfairchild any update on this issue?

[antoinepln]

Hey, @camfairchild . I have three examples showing the cost differences for a remove stake transaction, whether it's done alone, through a proxy, or in a batch.

1. Simple stake transaction costs 0 TAO

2. Stake transaction via a proxy account costs 0.000700912 TAO

https://taostats.io/extrinsic/4811868-0014?network=finney

1. Stake transaction in a batch 0.000613037 TAO

Right now, these fees are blocking many use cases.

Hey @camfairchild , just a heads-up—the issue is still there in the final RAO testnet.

If we do a direct add_stake transaction in a subnet, it costs 0 TAO
But if we do the same transaction through a proxy call, it costs 0.000700914 TAO

Managing stake movements across multiple subnets like this is not sustainable. It makes proxy management and transaction batching impossible, which hurts efficiency for both the chain and its users.
