Life cycle patterns

A Solidity contract is created either by deploying a new contract or by creating from within a contract. Apart from these, a contract and its functions can follow a different life cycle.

Similarly, using the timestamp's global variables and time units, contract states can also be moved. It is also possible to allow the contract functions to be called based on these timestamps. Let's look into the life cycle design patterns.

Mortal pattern

The mortal pattern allows a contract to be destroyed from the Ethereum blockchain. As you know...
