What's new in 2.9.1

  • Added a new internalErrorCode field in the FireblocksError class to provide additional information on specific errors.

What's new in 2.9.0

  • Resolved an issue that occurred during key generation when a device setup was incomplete.
  • Resolved a concurrency issue that arose when attempting to join a wallet containing multiple keys.
  • Implemented a restriction to prevent the usage of internal classes, enhancing security and code integrity.

What's new in 2.8.2

  • Fixed an issue where key generation could fail if initiated immediately after SDK initialization.

What's new in 2.8.1

  • Resolved an issue when verifying certificates concurrently.

What's new in 2.8.0

  • Resolved a minor issue in the MPC code.

What's new in 2.7.0

In version 2.7.0, we've introduced a few enhancements:

  • Improved log collection.
  • Resolved an issue when trying to sign a transaction that has failed or will fail before it can even be signed.
  • Improved error visibility: wrong passphrase in the recovery process is now explicitly mentioned in the returned error as WRONG_RECOVERY_PASSPHRASE (603)
  • The SDK is now being built with Android 14 (API Level 34). For more information please see here.

What's new in 2.6.0

In version 2.6.0, we've introduced a few major enhancements.

  1. Direct reporting of errors to Fireblocks. This will ease the process of supporting and debugging issues in the future. More information can be found here.
  2. Our MPC ceremony processes have been enhanced for greater robustness. MPC messages will now undergo multiple retry attempts before failing.
  3. Unexpected device errors, as seen in Common Errors will now result in the expected messaging, and not in a timeout.
  4. You can now dynamically extend wallets! Expand the range of algorithms available in a wallet by adding, for instance, EdDSA alongside ECDSA. Learn more here.

What's new in 2.5.0

In version 2.5.0, we've introduced several enhancements and additions to the SDK functionality:

  1. New Functionality: We've added a new function called stopSignTransaction to the SDK interfaces. This function enables users to stop and cancel transactions that were initiated for signing by the SDK.
  2. Enhanced error handling for quick transaction signing failures caused by invalid messages from the backend, such as schema changes in the message response from the backend.
  3. We've addressed a few edge cases in the mpcKeyGeneration process that could potentially result in key generation failures. These improvements enhance the overall stability and reliability of the SDK.

Upgrade guidelines

  1. In case of an exception, GenerateMPCKeys is no longer returning an empty Set, but a Set with keys and their appropriate statuses. You will need to validate that the keys are all in status Ready in order to verify that the setup is complete. Please See the following example for clarifications.
  2. All KeyRecovery properties are now optional. This may come into effect in a similar code to this one.
  3. All KeyDescriptor properties are now optional. This may come into effect in a similar code to this one.

What's new in 2.4.0

In version 2.4.0, we've expanded the capabilities of the NCW SDK to support Solana and Algorand, now including the EdDSA algorithm alongside our existing ECDSA support. This enhancement enables a single wallet to seamlessly interact with Bitcoin, various EVMs, and Solana.

More information about the supported NCW networks may be found here .

Additionally, we're excited to announce that support for more blockchains, including Stellar, is on the horizon. Stay tuned for further updates!

Upgrade guidelines

To successfully utilize the generateMPCKeys function with MPC_EDDSA_ED25519, it's essential that your workspace supports EdDSA. Learn more about supporting multiple algorithms within a single wallet here.

What's new in 2.3.0

In version 2.3.0, we made significant performance improvements in transaction signing.

For additional tips on enhancing overall performance, refer to our documentation here.

What's new in 2.2.8

In version 2.2.8, we made significant performance improvements in key generation and transactions.

For additional tips on enhancing overall performance, refer to our documentation here.

What's new in 2.2.5

In version 2.2.5, we have added the ability to work with multiple devices in a single wallet.

For more information about multiple devices, refer to our documentation here.

What's new in 2.1

In version 2.1, we added a safer backup and recovery mechanism.

Breaking change

Version 2.1 introduces a breaking change since the following two functions in the interface will receive different parameters:

  • backupKeys
  • recoverKeys

You can find details about the implementation in our android-ncw-demo repo and more information about the backup procedure here.

Upgrade guidelines

When upgrading to version 2.1 and later, you should require the user to run another backup procedure so that the new encrypted backup share on the Fireblocks servers will be associated with a passphraseId.
