BTT Token Presale Contract

This Solidity smart contract allows users to participate in a presale event by purchasing BTT tokens using ETH or USDC tokens. The contract is developed using Solidity and Foundry.

Features

Presale Duration: The contract supports a specific duration for the presale period.
Token Allocation: A fixed amount of BTT tokens are available for sale.
Multiple Payment Options: Users can participate using either ETH or USDC.
Fund Withdrawal: The collected ETH and USDC can be withdrawn by the contract owner.

Requirements
