Root + Impact

Description

• The contract sets buy fee as:

• However, tokens are minted as:

Since ERC20 defaults to 18 decimals, minting amount results in minting only amount wei of tokens.

Risk

Likelihood:

• Users may overpay significantly and receive incorrect token amounts.

• Example: If user buys 1 token, they receive 1 wei of Snow, not 1e18.

  However, they pay fee scaled to full token precision.

  This results in massive overpayment relative to received tokens.

Impact:

• Users may overpay significantly and receive incorrect token amounts.

• Token economics broken

Users pay 1 ETH for 1 wei token (depending on configuration)

• Severe imbalance between cost and token supply

Proof of Concept

Recommended Mitigation

Scale mint amount Or override decimals to 0 if integer token is intended.
