enhancement: estimated cost of gas for transaction

[perryascott]

The user should be able to create a new Transaction object and estimate how much gas it will cost to execute the transaction.

Ideally, less information is required to retrieve this information. I'm ill-informed on the variables that go into gas cost. If it's possible, maybe the user only needs to provide the following to a function:

• number of orders
• whether it's an offer/cancel
• pair

To receive an estimate of the gas cost.

Hi @perryascott

We pushed an update to the repo recently whereby if gas is not passed in the Transaction object then when placing the transaction the gas cost is automatically estimated.

This has the additional benefit of verifying that the transaction would occur successfully on chain.

The update in question is here: #56

As such if you are currently passing gas values to transactions you should be able to remove this.

I'm not sure but this may solve what you are talking about above.

However I can also look at exposing the estimate_gas call on a transaction. However, I would need to look into how to do this. Let me know if you want me to look into this

@adamamsmith from my understanding, the goal here would be to expose the estimated gas cost to the user before the transaction is actually executed. that way, they can build more responsive systems that are more gas conscious, correct me if i am wrong @perryascott. today, we ship the transaction before giving the user the chance to check the estimated gas cost.

Hey @adamamsmith,

Thanks for the well thought out answer. That's exactly what I need. Thank you!
