The genesis of the chain can be found in the [configs] (https://github.com/reddio-com/itachi/tree/main/conf/genesis) folder. The genesis is defined in the form of a JSON file containing the following:
- contract_classes: list of maps containing the class hash and the class.
- contracts: list of maps containing the contract address and the associated class hash.
- storage: list of tuples containing the storage key and the storage value. Please note that the storage key is itself a tuple, containing the contract address for which storage is set and the Starknet storage key.
The below defines all hardcoded values set in the geneses:

The node storage is prefilled using the genesis in order to allow access to prefunded accounts. Available accounts with unlimited funds are 0x1, 0x2, 0x3 and 0x4 (hence why the storage value we write is 0xffffffffffffffffffffffffffffffff for U256 low and U256 high).
Additionally, a public key (0x3603a2692a2ae60abb343e832ee53b55d6b25f02a3ef1565ec691edc7a209b2) is set for accounts 0x2 and 0x3, for which the signature will be checked during the validation phases of the execution. Accounts 0x1 and 0x4 include an empty validation phases, meaning no signature is required to execute any transactions going through them.
Finally, 0x1 is set as the contract owner of contract 0x040e59c2c182a58fb0a74349bfa4769cbbcba32547591dd3fb1def8623997d02, which is deployed as a ERC721 contract (given the class hash of 0x80000).
