The reuse of contracts is a great way for developers to save time and resources when developing. By forking existing contracts on bettercalldev, developers can easily customize the parameters of the contract to meet their needs. This is a great way to quickly create contracts without having to write the entire code from scratch. On the other hand, developers can also reuse contracts easily with the fork option on better call dev now. This allows developers to quickly copy existing contracts and make minimal changes to them without having to write the entire code again. By utilizing these tools, developers can save time and resources, as they don't need to create the contracts from scratch.
