## Key Functionality  

### **Token Association**  
Before burning tokens, they must be associated with the contract. This allows the contract to recognize and accept the tokens for destruction.  

- **Batch Association**: Users or administrators can associate multiple Hedera **token IDs** with the contract in a single transaction.  
- **Permanent Association**: Once a token is associated, users can freely send their **fungible tokens** or **NFTs** to the contract address to burn them.  
- **Trustless Execution**: The **DaVinciGraph platform provides a user-friendly UI** to simplify the burning process, but anyone can manually send assets to the contract for burning without third-party involvement.

## Supported & Unsupported Assets  

### ✅ **Supported for Burning**  
- **Fungible Tokens** (HTS-based tokens with standard fee structures)  
- **Non-Fungible Tokens (NFTs)** (HTS-based without custom fees)  

### ❌ **Not Supported**  
- **NFTs with Custom Fees**: These tokens are not supported due to restrictions that could prevent permanent burning.

## How It Works  

1. **Token Association**:  
   - A user or administrator initiates the process to associate specific tokens with the contract.  
2. **Token Burning**:  
   - Once associated, users can **send their assets directly to the contract address** for burning.  
3. **Finality**:  
   - The contract has **no withdrawal functions**, ensuring that **all sent tokens are permanently removed from circulation**.

## Features  

- **Irreversible Token Burning**: Assets sent to the contract are permanently destroyed.  
- **Supports Both Fungible & Non-Fungible Tokens**: Works with HTS-based fungible tokens and standard NFTs.  
- **Batch Token Association**: The contract allows **associating multiple tokens in one transaction** for efficiency.  
- **Seamless UI Integration**: **DaVinciGraph** provides a friendly UI to facilitate token burning, but the contract operates independently on-chain.  
- **Immutable & Trustless**: The contract **cannot be modified or reversed**, ensuring absolute finality in token burning.  



The BlackHole V2 contract is a powerful and immutable burn mechanism designed to permanently remove both fungible and non-fungible tokens (NFTs) from circulation. It serves as a trustless, irreversible asset-burning solution, ensuring that tokens sent to it are destroyed and unrecoverable.

This contract is designed to work seamlessly with all standard Hedera tokens, with one exception: non-fungible tokens (NFTs) with custom fees cannot be burned due to potential withdrawal complications.
