TokenPresale Smart Contract

Overview

The TokenPresale smart contract facilitates the sale of a specific ERC-20 token at a predetermined rate in exchange for Ether (ETH). It includes features such as pausing, ownership control, and a cap on the total ETH that can be raised during the presale.

Important Variables

• token: The ERC-20 token being sold.
• rate: The rate at which tokens are exchanged for ETH, denominated in wei.
• cap: The maximum amount of ETH that can be raised during the presale.
• weiRaised: Total amount of ETH raised so far.

We have to input marketing, cex, dev wallet initially when deploying, these wallets are

Max transaction amount is 3% of the supply, maxWalletSize is 2% of th supply, taxSwapTreshold is 0.5% of the supply

To openTrade, send tokens to token address and amount of eth you want to supply for pair on uniswap, use function openTrading()

Tax wallet is the deployer wallet, which will get 90% of the token supply initially
