How could I create a new smart contract token and copy the balance of every address from an old contract.

Essentially fork a contract.

I want to make this a one time function in the contract so that it can only be called once. Or even better do it during the contract creation.

  • Is the smart contract to be forked already written or are you able to change it's code before it's deployment in anticipation of a possible fork?

  • It is already deployed. Been deployed for a year.

  • Is it a standard ERC20 token? Is the balance variable public?

You can create a new contract with method to get every addresses in the token contract, then you can just copy it to your own array of address and then just call balanceOf function and get the balance of all your new address accounts. It's simple if you are copy a erc20 token.

  • I know that, but I am not sure what code to write. I was hoping to get some code.

  • You can use the ""call" function after you create a instance of your token contract with its address
