Contract Address

The contract address is a unique identifier of the contract on StarkNet. It is a chain hash of the following information:

  • prefix - the ASCII encoding of the constant string “STARKNET_CONTRACT_ADDRESS”
  • caller_address - currently always zero
  • salt - part of the deploy transaction
  • contract_hash - see the docs
  • calldata_hash - array hash of the inputs to the constructor

The computation is roughly the following:

contract address
contract_address := pedersen(
    “STARKNET_CONTRACT_ADDRESS”,
    caller_address,
    salt,
    pedersen(contract_code),
    pedersen(constructor_calldata))
