Fees in StarkNet Alpha

This is the first time I learn about the mechanism of gas fee. The current mechanism is quite interesting that it needs a service to estimate the gas fee. One thing that I realized that on Argent wallet I cannot customize fee like on metamask. I guess it relates to mechanism in this article. In the future, optimization to reduce the cost is great for users. I have not understood the last sentence that you said: " introducing fee abstraction will allow network participants to specify fees in tokens other than ETH". Is this mean we can pay fee using other tokens than ETH?

Hello Lior,
Interesting post thank you!

I have a little question about the base_fee or β€œgas price floor”. Only max_fee are mentioned, for a particular reason, specific to StarkNet?
Are there any plans to implement this at a later date, or has the question not yet arisen?

For example:
Arbitrum have currently 0.1 gwei gas fees like base_fee for any transactions
Optimism have currently 0.001 gwei gas fees like base_fee for any transactions

Update

β€˜base_fee’ is a concept related to EIP-1559, given that Arbitrum and Optimism have forked Ethereum and end up with the same codebase.

Thanks @henri.lieutaud for your help!
