Yes, you can fork any contract on BetterCallDev with parameters that you like. This is a great feature as it allows you to customize contracts to your own needs. You can fork the Michelson language which is the language used to write smart contracts on the Tezos blockchain. By forking the contract, you can make any changes to the code that you want, such as setting different parameters or adding new features. This makes it easier to customize contracts to suit your own needs, allowing you to create contracts that are tailored to your specific requirements.
