NFT drop :delayed release

Is there any way in algorand to create a delayed NFT drop? Where the NFT which is minted has a locked metadata hash and anyone purchase that NFT. After a particular date that NFT will be released and the buyer can actually see what they bought.

Hey! What would be the command to deploy this smart contract on the network?

Thanks! If you could provide me with any sample for the creation of ASA using smart contracts and steps to run the code, please. unable to run the code defined in docs.

Yeah! that means the complication/deployment of the smart contract will be done using goal command not any simple java transaction.

And while implementing the use case mentioned above while creating a group tnx (Application call, OptIn and ASA transfer) Getting this error If you have any idea about it

Thanks! If you could share how to create ASA using smart contracts. Is it using the goal command? Binding goal with smart contract to check for the constraints (verifications of constraints passed as arguments in goal command) Or any other way?

Hello! I have few questions around algorand smart contracts and ASA creation. Questions:

1. Creation of ASA can be done using some sdk or it can be done using smart contracts?
2. The approach I am following in an application is I created an ASA using normal java transaction.
