[General] RPC is giving vastly incorrect estimates

Provide a brief description of the functionality you're trying to implement and the issue you are running into.

This is from Pyth (Our oracle and RNG provider).

They we're having troubles with the gas estimations provided by the RPC (https://api.testnet.abs.xyz/) where the estimations were off so the callback was erroring (request random number -> Pyth estimates gas usage using the RPC and calls the callback fn in contract with random number with estimated gas + buffer).

Seems to only be a problem they've encountered with Abstract, was curious if you guys have come across something like this before?

Quote:

"I am not 100% sure what the root cause is, but the gas estimates we are getting from our RPC for this specific blockchain don't seem to be enough for the transactions to land. I'm guessing it's because of how zksync charges gas for state updates, but I am not certain.

the gas estimates are somehow quite far off -- we're getting 291k on the estimate, but the tx fails until we submit with 1.1M"

Thanks for the report! This aligns with the information we received from other users, and we're currently investigating the possible causes.

We have discovered an issue with the Abstract testnet configuration and it has already been fixed. From now on, the fee information from the RPC should be accurate.
