The Options smart contract is an ERC20 token designed for speculative betting on Ethereum's price movement. It allows users to bet on the increase or decrease of ETH's price, using the WETH/USDT pair from Uniswap for price reference. This contract is built on Solidity and leverages OpenZeppelin's ERC20 standard and ReentrancyGuard for enhanced security and functionality.

• constructor()
  • Initializes the contract, mints 1,000,000 OPTION tokens to the contract itself, and sets up the Uniswap WETH/USDT pair for price checking.

• eth_price_check()
  • 📈 Returns the current ETH price based on the Uniswap WETH/USDT pair's reserves.

• buy()

  • 📊 Allows a user to bet on the increase of ETH's price. When called, it requires the user to send 0.01 ETH and records the current ETH price as the user's BuyPrice.
  • 📝 Emits a BuyPriceSet event.

• sell()

  • 🔻 Allows a user to bet on the decrease of ETH's price. Similar to buy(), it requires 0.01 ETH and records the current price as the SellPrice.
  • 📝 Emits a SellPriceSet event.

• getBuyPrice()

  • 📌 Returns the BuyPrice set by the calling user, if it exists.

• getSellPrice()

  • 📌 Returns the SellPrice set by the calling user, if it exists.

• fallback()

  • A fallback function to handle ETH sent directly to the contract.

• receive()

  • A receive function to handle plain ETH transfers to the contract.

Users of this contract can speculate on Ethereum's price movement. By calling buy() or sell(), users bet on the price going up or down, respectively. The contract uses the Uniswap WETH/USDT pair to determine the current price of ETH and compares it with the user's bet. Successful predictions can be integrated with reward mechanisms (not implemented in this contract).

This contract employs ReentrancyGuard from OpenZeppelin to prevent reentrancy attacks, a common vulnerability in smart contracts dealing with financial transactions.

This contract is a demonstration of ERC20 token functionality and speculative betting mechanics. Users should exercise caution and understand the risks involved in blockchain-based betting. The contract should be thoroughly audited before any real-world implementation.
