Release v2.10.1

Release Notes

New Feature: Twin Ownership Transfer

A new two-party ownership transfer flow has been introduced for twins. This is especially useful if the mnemonic controlling a twin may have been leaked, allowing the owner to quickly transfer control to a new secure account.

• Initiate transfer: Current owner requests transfer to a new account.
• Accept transfer: The new account accepts to finalize.
• Cancel transfer: Current owner can cancel a pending transfer at any time.
• Balance handling: On acceptance, reserved balances tied to the twin are moved to the new owner, and ownership/indexes are updated.

Key Details

• One pending transfer per twin at a time.
• Transfer requires two-party consent (owner + recipient).
• Defensive checks ensure consistency of ownership and accounting.
• created_at timestamp stored for potential future expiry logic.

Events

• TwinTransferRequested, TwinOwnershipTransferred, TwinTransferCanceled → each includes request_id, twin_id, from, and to.

Compatibility

• Backward compatible, no storage migration required.

Security

• Designed for rapid recovery in case of compromised credentials (leaked mnemonic).
• Ownership and balances update atomically, ensuring integrity.

⚠️ Limitation

After ownership is transferred, it may take some time for the new public key used for RMB end-to-end encrypted communication to propagate across the network due to caching. During this window, users may experience temporary service degradation.
