- org.ldk.structs.TrustedCommitmentTransaction

```
public class TrustedCommitmentTransaction
extends Object
```
A wrapper on CommitmentTransaction indicating that the derived fields (the built bitcoin transaction and the transaction creation keys) are trusted. See trust() and verify() functions on CommitmentTransaction. This structure implements Deref.

`BuiltCommitmentTransaction`	`built_transaction()`	The pre-built Bitcoin commitment transaction
`ChannelTypeFeatures`	`channel_type_features()`	Should anchors be used.
`protected void`	`finalize()`
`Result_CVec_ECDSASignatureZNoneZ`	`get_htlc_sigs(byte[] htlc_base_key, DirectedChannelTransactionParameters channel_parameters, EntropySource entropy_source)`	Get a signature for each HTLC which was included in the commitment transaction (ie for which HTLCOutputInCommitment::transaction_output_index.is_some()).
`TxCreationKeys`	`keys()`	The pre-calculated transaction creation public keys.
`Option_usizeZ`	`revokeable_output_index()`	Returns the index of the revokeable output, i.e.

  - txid
```
public byte[] txid()
```
    The transaction ID of the built Bitcoin transaction
  - built_transaction

    The pre-built Bitcoin commitment transaction
  - keys

    The pre-calculated transaction creation public keys.

  - get_htlc_sigs
```
public Result_CVec_ECDSASignatureZNoneZ get_htlc_sigs(byte[] htlc_base_key,
                                                      DirectedChannelTransactionParameters channel_parameters,
                                                      EntropySource entropy_source)
```
    Get a signature for each HTLC which was included in the commitment transaction (ie for which HTLCOutputInCommitment::transaction_output_index.is_some()). The returned Vec has one entry for each HTLC, and in the same order. This function is only valid in the holder commitment context, it always uses EcdsaSighashType::All.
  - revokeable_output_index
```
public Option_usizeZ revokeable_output_index()
```
    Returns the index of the revokeable output, i.e. the `to_local` output sending funds to the broadcaster, in the built transaction, if any exists. There are two cases where this may return `None`: - The balance of the revokeable output is below the dust limit (only found on commitments early in the channel's lifetime, i.e. before the channel reserve is met). - This commitment was created before LDK 0.0.117. In this case, the commitment transaction previously didn't contain enough information to locate the revokeable output.
  - build_to_local_justice_tx
```
public Result_TransactionNoneZ build_to_local_justice_tx(long feerate_per_kw,
                                                         byte[] destination_script)
```
    Helper method to build an unsigned justice transaction spending the revokeable `to_local` output to a destination script. Fee estimation accounts for the expected revocation witness data that will be added when signed. This method will error if the given fee rate results in a fee greater than the value of the output being spent, or if there exists no revokeable `to_local` output on this commitment transaction. See [`Self::revokeable_output_index`] for more details. The built transaction will allow fee bumping with RBF, and this method takes `feerate_per_kw` as an input such that multiple copies of a justice transaction at different fee rates may be built.
