Implement a 2% sell tax and accumulate the funds in an NFT buyback pool.
Target NFT collection (CMD):
0x5d750ce0d452c7f22a2feecbbcfcb56d496728ad
Introduce a permissionless buyback function:
- Any user can trigger a buyback by submitting a valid marketplace order
The contract must verify:
- the NFT belongs to the target collection
- the purchase price does not exceed the available pool balance
Execution:
- The contract executes the purchase using the provided order
- The acquired NFT is immediately sent to a burn address
Constraints:
- Do not rely on on-chain floor price calculations
- Do not integrate complex price oracles
- Ensure gas-efficient and secure execution
Optional:
- Add a small incentive fee for the caller to trigger the buyback
