Calling Other Functions

A contract is a collection of persistent state variables and functions which may manipulate these variables.

Functions and state variables within a contract's scope are said to belong to that contract. A contract can only access and modify its own state.

If a contract wishes to access or modify another contract's state, it must make a call to an external function of the other contract. For anything to happen on the Aztec network, an external function of a contract needs to be called.

Contract​

A contract may be declared and given a name using the contract keyword (see snippet below). By convention, contracts are named in PascalCase.

contract keyword
contract MyContract {

    // Imports 

    // Storage 

    // Functions
}
A note for vanilla Noir devs

There is no main() (GitHub link) function within a Noir contract scope. More than one function can be an entrypoint.

To understand how to call a function from another contract, follow the crowdfunding tutorial.
