What are the three major benefits of smart contract?

They are a faster, cheaper, and more secure way of executing and managing agreements . The technical difficulty of making changes and the inability to handle complex transactions are some issues with smart contracts that need to be rectified to gain mass adoption.

They typically are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary’s involvement or time loss.

Another way to call contracts from a smart contract is to use a mechanism like dependency-injection . With this method, the caller can instantiate the contract it wants to call and knows the type signature of the function, which also has the nice side-effect, that return-values can be received.
