# 0.18.0

**Released on November 26th, 2025**

* merge utxos command

*you can now easily perform utxos merging for you by simply calling the method `mergeHoldingUtxos`, this returns a series of commands that each needs to be executed
individually to merge the assets. It returns a list of utxos commands because: Firstly, it supports multi-assets (so it will merge both CC and non-CC tokens)
and secondly there is an upper limit of 100 inputs per transaction so to facilitate if more is present then it splices it for the client.*

```javascript theme={"theme":{"light":"github-light","dark":"github-dark"}}
const [mergeUtxoCommands, mergedDisclosedContracts] =
    await sdk.tokenStandard!.mergeHoldingUtxos()!

for (let i = 0; i < mergeUtxoCommands.length; i++) {
    await sdk.userLedger?.prepareSignExecuteAndWaitFor(
        mergeUtxoCommands[i],
        keyPairSender.privateKey,
        v4(),
        mergedDisclosedContracts
    )
}
```

* merge utxos delegation

*instead of manually monitor and act you can set up utxos merge delegation as described at* [merge-delegation](https://docs.dev.sync.global/app_dev/token_standard/index.html#setting-up-mergedelegations)
*using the new functionality like. An example of the complete setup can be found here:* [Wallet SDK example 18](https://github.com/canton-network/wallet/blob/main/docs/wallet-integration-guide/examples/scripts/18-merge-delegation-proposal.ts)

* create party with preapproval

*creating a party with preapproval is such a common task that we have decided to add is a combined function similar to lots of other cases.*

```javascript theme={"theme":{"light":"github-light","dark":"github-dark"}}
const receiver =
    await sdk.userLedger?.signAndAllocateExternalPartyWithPreapproval(
        keyPairReceiver.privateKey,
        validatorOperatorParty,
        instrumentAdminPartyId,
        'bob'
    )
```

* get traffic status

*in previous release we enabled the purchase of traffic using an external party, now we have included an option to fetch the balance so you can check if
you actually need to top up with an external party. However this does require providing a scanApiBaseUrl to the tokenStandardController.*

```javascript theme={"theme":{"light":"github-light","dark":"github-dark"}}
const trafficStatus =
    await sdk.tokenStandard!.getMemberTrafficStatus(participantId!)
```

* list holdings at offset

*listHoldingsUtxo have been extended with an optional offset parameter, normally it uses the ledgerEnd, but this allow you to define it yourself.
Do be warned that this is not a performant operation.*
