## Deploy a stateful contract through a stateful contract

No I don’t use a stateless smart contract. When the user wants to create a transaction (survey or vote) he concatenate all the parameters creating a message and signs it. Then the transaction is composed and signed by the central account using the user parameters in the appropriate fields (applicati…

## Deploy a stateful contract through a stateful contract

## Deploy a stateful contract through a stateful contract

Is it possible to save a stateful contract template inside a stateful contract so that a new stateful contract is created when a certain event occurs? Assuming we have two types of smart contracts: Stateful A: it manages a list of whitelisted accounts and allows them to create type B smart contrac…

## Is there any framework for unit tests for smart contracts?
