Failing tests requiring USC that supports Sierra 1.7.0

[FabijanC]

Currently our integration forking tests are failing because Devnet can't handle the latest Sierra artifacts. This is the reported error:

Sierra compilation error: Unable to compile Sierra to Casm. No matching ContractClass or CasmContractClass found for version 1.7.0: undefined

A new version of USC should help. Waiting for:

• Add support for sierra 1.7.0 software-mansion/universal-sierra-compiler#62
• Release v2.4.0-rc.0 software-mansion/universal-sierra-compiler#67

I am not able to resolve the issue by simply updating USC to 2.4.0-rc.0

• blockifier v0.8.0 (currently specified as a Devnet dependency), doesn't work with cairo-lang* packages required by USC 2.4.0-rc.0.
• Even upgrading blockifier can't help
  • Currently on the latest commit of their 0.13.4 development branch it specifies cairo-lang-* packages of version 2.10.0-rc.0
  • USC specifies 2.10.0-rc.1
  • So from my understanding, even updating to the latest blockifier dev branch commit won't help until they update their dependencies

Temporary workaround, merged into main : #684

gm,

wondering if this possible now without using the fork flag? :)

If what is possible? Running into this issue?

To use the devnet with SIERRA 1.7.0.
Trying to declare some contracts compiled using https://github.com/starkware-libs/cairo/releases/tag/v2.10.0-rc.1

[FabijanC]

Not possible to declare Sierra 1.7.0 contracts until Devnet's USC (Universal Sierra Compiler) dependency is updated. We are working to resolve this, but it also requires updating the blockifier dependency to the latest version, which is much harder.

[FabijanC]

Good news is that a stable blockifier has just been released and we are working to integrate that and the latest USC in Devnet.

Is there any workaround while waiting for the PR to be merged?

You are advised to use the development branch starknet-0.13.4 which also contains this fix. The plan is to merge that branch into main. However, the branch comes with an update of JSON-RPC API to v0.8.0-rc.3, update of Rust to 1.83 and update of Starknet to 0.13.4.
