## 📖 Overview

DynamicVolumePricedToken (symbol: DVP) is an experimental ERC20-style token with a dynamic pricing mechanism that automatically adjusts the token price based on cumulative trading volume.

- No imports or constructors used — fully self-contained Solidity code.

- No input fields for core functions — everything is automatic.

- Dynamic price: increases as more tokens are bought or sold.

- Pure ETH-based economy — users buy and sell tokens directly from the contract.

## ⚙️ Features

| Feature | Description |

|----------|--------------|

| 🧮 Dynamic Pricing | Token price grows linearly with total volume traded. |

| 💸 Buy with ETH | Call buy() (payable) — tokens are minted based on current price. |

| 💰 Sell for ETH | Call sellAll() — sells your full balance for ETH at the current price. |

| 🔄 No Admin Needed | Fully autonomous — anyone can mint via seedMint() for testing. |

| 🧠 Deterministic Pricing | Based on basePrice + (cumulativeTokensTraded * basePrice) / slopeDenominator. |

## 🧠 Core Functions

### 1. buy() payable

Buy tokens with ETH at the current dynamic price.

- No inputs.

- Emits Bought event.

### 2. sellAll()

Sell your entire token balance for ETH at the current price.

- No inputs.

- Emits Sold event.

### 3. currentPricePerToken() → uint256

View the current token price (in wei).

### 4. quoteTokensForWei(uint256 weiAmount) → uint256

Estimate how many tokens you’d get for a given ETH amount.

### 5. quoteWeiForTokens(uint256 tokenAmount) → uint256

Estimate how much ETH you’d receive for a given token amount.

### 6. seedMint()

Mint 1000 test tokens to yourself — used for testing since no constructor exists.

## 💻 Example Usage (Remix or Web3)

### Buy tokens

```solidity

DynamicVolumePricedToken token = DynamicVolumePricedToken(0xDBEF45B4C5C4C0d572EC19B67f215DD212e5a116);

token.buy{value: 0.01 ether}();
