0.6.0

0.6.0

Released on September 16th, 2025
  • ledgerFactory, TopologyFactory & ValidatorFactory changed to use URL instead of strings (where applicable)
const myLedgerFactory = (userId: string, token: string) => {
    return new LedgerController(
        userId,
        new URL('http://my-json-ledger-api'), //HERE
        token
    )
}

const myTopologyFactory = (
    userId: string,
    userAdminToken: string,
    synchronizerId: string
) => {
    return new TopologyController(
        'my-grpc-admin-api',
        new URL('http://my-json-ledger-api'), //HERE
        userId,
        userAdminToken,
        synchronizerId
    )
}

const myValidatorFactory = (userId: string, token: string) => {
    return new ValidatorController(
        userId,
        new URL('http://my-validator-app-api'), //HERE
        token
    )
}
  • connectTopology now uses scanProxy instead of scan for proper decentralized setup
  • stronger typing now required strings of specific formats for parties across all controllers
  • fixed a bug where the combinedHash returned from topologyController.prepareExternalPartyTopology was in hex encoding instead of base64
const preparedParty = await sdk.topology?.prepareExternalPartyTopology(
    keyPair.publicKey
)

logger.info('Prepared external topology')

if (preparedParty) {
    logger.info('Signing the hash')
    const signedHash = signTransactionHash(
    //previously this would have to be converted from hex to base64
        preparedParty?.combinedHash,
        keyPair.privateKey
    )

    const allocatedParty = await sdk.topology?.submitExternalPartyTopology(
        signedHash,
        preparedParty
    )
  • fixed a bug that caused the expectedDso field to be required when performing TransferPreApprovalProposal (this is only required after Splice 0.1.11)
  • simplified setParty & setSynchronizer, now it can all be done with one call on sdk.setPartyId()
//the connects are still needed and should be run before sdk.setPartyId
await sdk.connect()
await sdk.connectAdmin()
await sdk.connectTopology(LOCALNET_SCAN_API_URL)

//Previously all these was required to get everything working
sdk.userLedger!.setPartyId(partyId)
sdk.userLedger!.setSynchronizerId(synchronizerId)
sdk.tokenStandard?.setPartyId(partyId)
sdk.tokenStandard?.setSynchronizerId(synchronizerId)
sdk.validator?.setPartyId(partyId)
sdk.validator?.setSynchronizerId(synchronizerId)

//New version
await sdk.setPartyId(partyId,synchronizerId)
//synchronizerId is optional, it will automatically select the first synchronizerId,
//that the party is connected to if, none is defined
