Assignment 2: Create an “actual” Token

The goal of this assignment is to create your first Aleo token following the current community adopted token standard: ARC21.

Following the specifications in chapter 5.4, your goal is to write a program managing such a token: by handling the registration and initial coin offering of the token. It must import the token_registry.aleo program:

import token_registry.aleo;

Learning Objectives

By completing this assignment, you will:

• Understand how to use the token community standard

• Write your first DeFi program

Tasks

Your program must include the following transitions:

1. initialize: it is responsible for registering the token, calling token_registry.aleo/register transition. Your token metadata such as token ID, max supply, name... should all be defined as constants at the beginning of your program.

2. mint: it is the transition called by users directly to mint the token token_registry.aleo/mint_public. This minting should be allowed only after a certain block height, defined as a constant MINT_START_HEIGHT. Upon minting, the minter should transfer publicly Aleo credits to a TREASURY address defined as a constant. MINT_PRICE constant will define the price to mint per token.

3. update_admin: a transition to update the token admin with the address provided as an input, it calls token_registry.aleo/update_token_management to do so.

1. Also, add as a comment at the end of the program the command that will be executed to initialize the token:

leo execute initialize #...
