We commit these artifacts so that the compilation process is easier, as they require different cairo 0 / cairo 1 versions.

The OZ contracts were compiled as to match the starkli's allowed class hash list: OpenZeppelin v0.13.0 compiled with cairo v2.6.3.

git clone https://github.com/OpenZeppelin/cairo-contracts
cd cairo-contracts

SCARB_VERSION=2.6.3
OZ_VERSION=0.13.0

git checkout v$OZ_VERSION
asdf install scarb $SCARB_VERSION
asdf shell scarb $SCARB_VERSION
scarb build
starkli class-hash target/dev/openzeppelin_AccountUpgradeable.contract_class.json

should always return class hash 0x00e2eb8f5672af4e6a4e8a8f1b44989685e668489b0a25437733756c5a34a1d6, and target/dev/openzeppelin_AccountUpgradeable.contract_class.json should match the file in this folder.

openzeppelin_ERC20Upgradeable.contract_class.json is compiled using the same scarb and OZ versions.
