Token with Mintable Supply
A fungible token with a mintable supply can be minted once and has the functionality to mint additional tokens throughout its lifetime.
The smart contract template for fungible tokens with a mintable supply is suited for uses cases where the token should follow additional issuance in the future. After deployment, new tokens can be created.
