my code is here

```auto
let balances = wallet.get_balances().await.unwrap();
     println!("balances: {:?}", balances);
    let asset_id = contract_instance.methods().asset_id(sub_id).call().await.unwrap();
    let asset = asset_id.value;
    println!("asset {:?}",asset);
    let burn = contract_instance.methods().burn(sub_id,1).with_variable_output_policy(VariableOutputPolicy::EstimateMinimum).with_tx_policies(TxPolicies::default()).call().await;
    dbg!(&burn);

```

response is here

You need to include the asset that is burned in the call pararmeters:

```auto
let call_params = CallParameters::new(amount, asset_id, 1_000_000);
    let burn = contract_instance
.methods()
.burn(sub_id,1)
.with_variable_output_policy(VariableOutputPolicy::EstimateMinimum)
.with_tx_policies(TxPolicies::default())
.call_params(call_params)
.call()
.await;

```

Can this be an asset that can only be burned at your own address? If you have contractual authority, can’t you burn nft at other addresses?

Only the minting contract has the ability to burn as the `AssetId` is the hash of the `ContractId` and `SubId`

If there is an nft AssetId on address A, address B has contract burn authority, can address B burn off A’s AssetId?

For any asset to be burned, it must be sent to or owned by the contract that minted it.

</div>

That is, if address A does not have this nft asset, it cannot burn the asset at address B, unless address B transfers the asset back to address A, or the contract, address A has the right to burn this asset
