Refundable Bonding Curve
Purpose
The SuperMemeRefundableBondingCurve contract implements a bonding curve mechanism that allows users to buy tokens and request refunds under specific conditions. It ensures fair token distribution and provides the option to retrieve invested ETH when needed.
Core Functions
buyTokens(uint256 _amount)
Description: Enables users to purchase tokens using ETH. The cost is dynamically calculated based on the bonding curve mechanism.
Parameters:
_amount(uint256): The number of tokens the user wishes to purchase.
Requirements:
_amount > 0.msg.valuemust meet the minimum buy amount.The bonding curve must not be completed.
The contract must not be in refund-only mode.
Behavior:
Verifies user eligibility and calculates the token cost.
Deducts a trade tax and mints tokens to the buyer.
