declare

pub fn declare(contract_name: ByteArray, fee_settings: FeeSettings, nonce: Option<felt252>) -> Result<DeclareResult, ScriptCommandError>

Declares a contract and returns DeclareResult.

• contract_name - name of a contract as Cairo string. It is a name of the contract (part after mod keyword) e.g. "HelloStarknet".
• fee_settings - fee settings for the transaction. Can be Eth or Strk. Read more about it here
• nonce - nonce for declare transaction. If not provided, nonce will be set automatically.
