2023-AUG-02

Added support for Base Mainnet.

2023-JUL-18

Released React Native WaaS SDK 2.0.0.

2023-MAY-31

Released React Native WaaS SDK 1.0.2.

FIXES

Updated APIs and sample demos to enable better handling of operations:

• Improved the following APIs to return the resource name of the resulting WaaS operation on successful initiation: createSignatureFromTx, prepareDeviceArchive, prepareDeviceBackup.
• Updated the Sample Project: MPCSignatureDemo, MPCKeyExportDemo, DeviceBackupDemo and DeviceAdditionDemo to process the operations that are created in the operation initialization call, instead of the last operation manifested in the result of ListMPCOperations.
• Updated SDK API by removing the convenience method computeMPCWallet. The clients should ideally use computeMPCOperation and computePrepareDeviceArchiveMPCOperation (SDK) for MPCWallet creation in a Proxy server model.
