Additional crontract functions:

* Mintable - release of new tokens in a smart contract.
* Pausable - a function for the owner that allows you to stop all transactions in the smart contract.
* Blacklist - a function for the owner, which allows you to prohibit any address from conducting transactions in a smart contract.
* Burnable - a function that makes it possible to destroy tokens.
* Burn fee - a function that allows you to burn a set percentage of tokens from each transaction.
* Dev/marketing fee - a function that allows you to set a commission from each transaction and send it to the specified address.
* Liquidity fee - a function that allows you to replenish the liquidity pool of the token by a certain percentage from each transaction.

&#x20; 7\.  After creating a token, it becomes possible to deploy a smart contract to the Testnet test network for free or to the main Mainnet network by paying a service fee.                    &#x20;
