0.7.0

​
0.7.0

Release on September 18th, 2025
  • Important!: scan api is not longer used for methods like connectTopology use scan proxy instead
  • Added support for multi-hosting a party upon creation against multiple validators
// setup config against multiple nodes to acquire signature
const multiHostedParticipantEndpointConfig = [
    {
        adminApiUrl: '127.0.0.1:2902',
        baseUrl: new URL('http://127.0.0.1:2975'),
        accessToken: adminToken.accessToken,
    },
    {
        adminApiUrl: '127.0.0.1:3902',
        baseUrl: new URL('http://127.0.0.1:3975'),
        accessToken: adminToken.accessToken,
    },
]

const participantIdPromises = multiHostedParticipantEndpointConfig.map(
    async (endpoint) => {
        return await sdk.topology?.getParticipantId(endpoint)
    }
)
const participantIds = await Promise.all(participantIdPromises)

const participantPermissionMap = new Map<string, Enums_ParticipantPermission>()

// decide on Permission for each participant
participantIds.map((pId) =>
    participantPermissionMap.set(pId!, Enums_ParticipantPermission.CONFIRMATION)
)

// setup multi-hosting for a party against
await sdk.topology?.prepareSignAndSubmitMultiHostExternalParty(
    multiHostedParticipantEndpointConfig,
    multiHostedParty.privateKey,
    synchronizerId,
    participantPermissionMap,
    'bob'
)
  • Verify signed transaction hash
we have also extended the executeSubmission and prepareSignAndExecuteTransaction to validate the hash before transmitting to the ledger 
const hash = 'my-transaction-hash'
const publicKey = 'my-public-key'
const signature = 'my-signed-hash-with-private-key'
const isValid = sdk.userLedger?.verifyTxHash(hash, publicKey, signature)
  • wait for command completion
//it is recommended to fetch ledger offset before preparing your command
const offsetLatest = (await sdk.userLedger?.ledgerEnd())?.offset ?? 0

const transferCommandId =
    // prepareSignAndExecuteTransaction & prepareSign now returns the commandId
    await sdk.userLedger?.prepareSignAndExecuteTransaction(
        [{ ExerciseCommand: transferCommand }],
        keyPairSender.privateKey,
        v4(),
        disclosedContracts2
    )

//new command that scans the ledger to ensure the command have completed
const completion = await sdk.userLedger?.waitForCompletion(
    offsetLatest, //where to start from
    5000, //optional timeout in ms
    transferCommandId! //the command to look for
)
  • Added new endpoint to quickly fetch all pending 2-step incoming transfer to easily accept or reject
const pendingInstructions = await sdk.tokenStandard?.fetchPendingTransferInstructionView()

const [acceptTransferCommand, disclosedContracts3] =
    await sdk.tokenStandard!.exerciseTransferInstructionChoice(
        transferCid,
        'Accept'
    )
  • optional expiry date for create transfer
const [transferCommand, disclosedContracts2] =
    await sdk.tokenStandard!.createTransfer(
        sender!.partyId,
        receiver!.partyId,
        '100',
        {
            instrumentId: 'Amulet',
            instrumentAdmin: instrumentAdminPartyId,
        },
        utxos?.map((t) => t.contractId),
        'memo-ref',
        new Date(Date.now()+60*1000) // custom expiry of 1 hour
        // default is 24 hours
    )
  • fetch transaction by update id
// convenient new endpoint to get transaction based on update id
// this will come out in same format as listHoldingTransactions
sdk.tokenStandard?.getTransactionById('my-update-id')
  • The access token generated by the authController is now correctly passed to the scan proxy and registry
