My implementation of DAO

Simple ICO implementation

Description

TEST test 222 The MyICO contract is a custom ICO (Initial Coin Offering) contract. It allows users to purchase tokens using USD and claim their tokens at a later time. Here are the important details of the contract:

• The contract has an initialize function that can only be called by the admin role to set the start times for buying and claiming tokens.
• The contract has a buyToken function that allows users to purchase tokens using USD. The function converts the USD amount to TST tokens based on the exchange rate and checks if the user's balance is within the allowed range.
• The contract has a \_getClaimable internal function that calculates the amount of tokens that can be claimed by a user based on the percentage and the user's purchased tokens.
• The contract has a getAvailableAmount function that calculates the amount of tokens that can be claimed by a user at the current time based on the elapsed time since the claim start.
• The contract has a withdrawTokens function that allows users to claim their available tokens. The function checks if the claim period has started and transfers the tokens to the user.
• The contract has a withdrawUSD function that can only be called by the admin role to withdraw the remaining USD tokens from the contract.

This contract provides a simple and secure way for users to participate in the ICO by purchasing tokens and claiming them at the appropriate time.
