Thank you so much! I'm going to review it later today.

@h4x3rotab I also tried to fix tests but seems there is code issue While trying to upload code to cluster I'm getting following errors in pruntime

DEBUG prpc{id=1463}: phala_mq: mq dispatching message: sender=Pallet("PhalaPhatContracts"), dest=phala/cluster/key    
DEBUG prpc{id=1463}:pink{blk=264}: runtime::contracts: new code rejected: use of floating point type in locals is forbidden    
ERROR prpc{id=1463}: phactory::system: Error processing message: Failed to upload code: "Module(ModuleError { index: 4, error: [26, 0, 0, 0], message: Some(\"CodeRejected\") })"

I thought it is related to phat/contracts/sub_price_feed/lib.rs:148 but it's not. Must be something in phat_offchain_rollup -> phat/crates/rollup cuz when I remove deps to it, uploading code works.
