# Burnable Approval

This example demonstrates how to create a burnable approval that allows tokens to be sent to the burn address, effectively removing them from circulation.

## Overview

A burnable approval enables tokens to be permanently destroyed by sending them to the zero address.

## Code Example

```typescript
const burnableApproval = new CollectionApproval({
    fromListId: '!Mint', // Excludes the Mint address
    toListId: 'bb1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqs7gvmv', // Burn address (bb-prefixed)
    initiatedByListId: 'All',
    transferTimes: UintRangeArray.FullRanges(),
    ownershipTimes: UintRangeArray.FullRanges(),
    tokenIds: UintRangeArray.FullRanges(),
    approvalId: 'burnable-approval',
    version: 0n,
    approvalCriteria: undefined, // No additional restrictions
});
```
