  • Add AccountUpdateTransaction.setProxyAccountId

Changed

  • Rename ContractExecuteTransaction.setAmount() to ContractExecuteTransaction.setPayableAmount()

Added

  • Client.forTestnet makes a new client configured to talk to TestNet (use .setOperator to set an operater)

  • Client.forMainnet makes a new client configured to talk to Mainnet (use .setOperator to set an operater)

  • Renamed TransactionRecord.contractCreateResult to TransactionRecord.getContractCreateResult()

v1.0.0-beta.3

Changed

Fixed

  • Fix usage on Node versions less than 12.x

v1.0.0-beta.2

Changed

  • CallParams is removed in favor of ContractFunctionParams and closely mirrors type names from solidity

    • addInt32
    • addInt256Array
    • addString
    • etc.

  • ContractFunctionResult now closely mirrors the solidity type names

    • getInt32
    • etc.

v0.8.0-beta.3

Changed

  • Client constructor takes the network as { network: ... } instead of { nodes: ... }

  • Transactions and queries do not take Client in the constructor; instead, Client is passed to execute.

  • Removed Transaction.executeForReceipt and Transaction.executeForRecord

    These methods have been identified as harmful as they hide too much. If one fails, you do not know if the transaction failed to execute; or, the receipt/record could not be retrieved. In a mission-critical application, that is, of course, an important distinction.

    Now there is only Transaction.execute which returns a TransactionId. If you don't care about waiting for consensus or retrieving a receipt/record in your application, you're done. Otherwise you can now use any TransactionId and ask for the receipt/record (with a stepped retry interval until consensus) with TransactionId.getReceipt and TransactionId.getRecord.

    v0.7.x and below

    let newAccountId = new AccountCreateTransaction(hederaClient)
    .setKey(newKey.publicKey)
    .setInitialBalance(1000)
    .executeForReceipt().accountId; // TransactionReceipt

    v0.8.x and above

    let newAccountId = new AccountCreateTransaction()
    .setKey(newKey.publicKey)
    .setInitialBalance(1000)
    .execute(hederaClient) // TranactionId
    .getReceipt(hederaClient).accountId; // TransactionReceipt

  • Rename setPaymentDefault to setPaymentAmount

Added

  • All transaction and query types that were in the Java SDK but not yet in the JS SDK (GetBySolidityIdQuery, AccountStakersQuery, etc.)

  • TransactionId.getReceipt

  • TransactionId.getRecord

  • Transaction.toString. This will dump the transaction (incl. the body) to a stringified JSON object representation of the transaction. Useful for debugging.

  • A default of 1 Hbar is now set for both maximum transaction fees and maximum query payments.

  • Smart Contract type encoding and decoding to match Java.

  • To/From string methods on AccountId, FileId, etc.

  • Internal retry handling for Transactions and Queries (incl. BUSY)

Removed

  • Transaction and Query types related to claims
