Check Nonce

[octavei]

Usually, we will check the nonce value in the transaction pool, which ensures normal transactions on our chain. Why in op, we don't do this kind of operation ?

[zsluedem]

The nonce value should be checked in the simulation step which inside the entrypoint(0.6.0 version) contract layer(or wallet layer). It is not explicitly checked in the bundler layer.

This way, everyone can't submit multiple operations at the same time. Since each op should add 1 to the Nonce on top of the previous op, the chain will definitely not pass when the simulation is executed

[zsluedem]

Ok. I see what you are trying to do here. This needs to be additionally taken care of. Are you facing this problem right now?

As a user, I want to submit multiple operations at the same time, and in one TX, they are all able to simulate execution success.
