Summary

This release enhances enterprise-grade transaction signing capabilities with new HSM support and improves code maintainability through strategic refactoring of core transaction handling methods.

Added

HSM-based Transaction Signing - Enhanced support for Hardware Security Module integration

• New SignableNodeTransactionBodyBytes class - Represents transaction body ready for external signing, explicitly paired with node account ID and transaction ID

v2.57.0

What's Changed

Summary

This release introduces support for HIP-1046 and enhances node configuration with a new gRPC web proxy field in the address book schema, enabling node operators to manage web proxies directly. It also adds the grpcWebProxyEndpoint field to NodeCreateTransaction and NodeUpdateTransaction for non-gRPC client compatibility. Additionally, new APIs allow for transaction size estimation prior to submission, supporting better fee calculation, validation, and batching logic.

Added

• Support for HIP-1046. https://hips.hedera.com/hip/hip-1046
  • Introduced new grpc web proxy field in the address book schema, making node operators manage their web proxies. #2337
  • NodeCreateTransaction
    • Endpoint grpcWebProxyEndpoint - A web proxy for gRPC from non-gRPC clients.
    • Endpoint getGrpcWebProxyEndpoint()
    • NodeCreateTransaction setGrpcWebProxyEndpoint(Endpoint)
  • NodeUpdateTransaction
    • Endpoint grpcWebProxyEndpoint - A web proxy for gRPC from non-gRPC clients.
    • Endpoint getGrpcWebProxyEndpoint()
    • NodeUpdateTransaction setGrpcWebProxyEndpoint(Endpoint)
• Support transaction size calculation before submission. This is useful for fee estimation, transaction validation, and batching logic. #2330
  • Following APIs were implemented: #2324

    • Transaction.size: uint
      Returns the total size (in bytes) of the protobuf-encoded transaction, including signatures and metadata.

    • Transaction.bodySize: uint
      Returns the protobuf-encoded transaction body size (excluding signatures), using a placeholder node account ID.

    • ChunkTransaction.bodySizeAllChunks: uint[]
      For chunked transactions (e.g. FileAppendTransaction, TopicMessageSubmitTransaction), returns an array of body sizes for each chunk.

Dependency Changes

• chore(deps): bump gradle/actions from 4.3.1 to 4.4.0 by @dependabot in #2341
• build: bump Gradle to 8.14 / gradle-conventions to 0.4.1 / example deps by @jjohannes in #2343

What's Changed

Added

Support for decline reward in node create and node update transaction.

Full Changelog: v2.56.0...v2.56.1

v2.56.0

What's Changed

Summary

This release enhances the Hedera SDK with improved account creation key management and network configuration fixes. The update focuses on more flexible key handling in account creation transactions and resolves an issue with address book propagation in network configuration.

Enhancements

Improved setECDSAKeyWithAlias and setKeyWithAlias for AccountCreateTransaction (#2319)
Updated and unified method signatures to accept a more flexible input type (Key)
Now properly handles both scenarios:

• If a PrivateKey is provided: Uses it to set the key and internally derives the alias from its corresponding public key
• If a PublicKey is provided: Uses it directly to set the key and derives the alias from that public key

Consistent outcome regardless of key input type is ensured (#2318)

Bug Fixes

Fixed issue where Client.setNetwork() did not propagate address book (#2317)
Now correctly attaches the corresponding address book on Node creation after setNetwork() invocation (#2322)

Dependency Changes

• chore(deps): bump org.springframework.boot:spring-boot-dependencies from 3.4.4 to 3.4.5 in /hiero-dependency-versions by @dependabot in #2314

Full Changelog: v2.55.0...v2.56.0

v.2.55.0

What's Changed

Summary

This release introduces HIP-551 Batch Transaction support, enabling atomic execution of transaction sequences with ACID properties through a new BatchTransaction class and related mechanisms. Additional improvements include TokenAirdropTransaction support, enhanced file handling for non-zero shards/realms, and a more robust retry mechanism for THROTTLED_AT_CONSENSUS responses using backoffs.

Added

• HIP-551 Batch Transaction Support

• Implemented HIP-551, enabling execution of dependent transactions as a single atomic unit satisfying ACID properties

• New BatchTransaction class containing lists of inner transactions and their IDs

• Introduced batchKey field in Transaction class that must sign the BatchTransaction

• Created new batchify method to prepare transactions for inclusion in a batch:

  • Sets the batch key
  • Marks transaction as part of a batch (inner transaction)
  • Signs with client operator
  • Freezes the transaction

• Enhanced freezeWith method to check if batchKey is null:

  • Null: Indicates transaction is not part of a batch
  • Present: Indicates transaction belongs to a batch (sets nodeAccountId to 0.0.0)

• TokenAirdropTransaction Support

  • New TCK method to handle TokenAirdropTransaction

Enhancements

• Not verifying the receipt for multiple THROTTLED_AT_COSENSUS responses. Also enhancing the retry mechanism for this status code using backoffs.

v2.54.0

What's Changed

Summary

This release adds support for HIP-1021, automatically assigning the autoRenewAccountId to the payer when no Admin Key is provided during topic creation. It also fixes issues with TopicUpdateTransaction, enabling proper clearing of custom fees, feeExemptKey, and feeScheduleKey. Several dependency updates improve stability and compatibility, including updates to JUnit, Mockito, Netty, and more. Additional enhancements improve overall SDK behavior and align with protocol changes.

Enhancements

• Support for HIP-1021: Improve Assignment of Auto-Renew Account ID for Topics (https://hips.hedera.com/hip/hip-1021). The autoRenewAccountId will automatically be set to the payer_account_id of the transaction
  if an Admin Key is not provided during topic creation #2301

Bug Fixes

• Upon TopicUpdateTransaction you are not able to clear the custom fees, feeExemptKey and feeScheduleKey #2284
  The logic is updated as follows:
  • If we have null list (that is the default value) → Do nothing (don’t send a request).
  • If we have empty list → Send a request to clear the list.
  • For Non-empty list → Send a request with the provided list.
  • clearFeeScheduleKey sets the key to empty KeyList.
