What's Changed

✨ Main Features

Keygen

Ability to trigger the key generation directly via the Gateway.

New User decryption share mechanism

Shares are no longer stored on-chain. Instead, they are now included in the event’s data on the Gateway.

PauserSet

A new PauserSet contract is available as a host and gateway contract used for the pausing mechanism.

Re-randomisation of transaction inputs

All inputs (including from state) of transactions are re-encrypted before evaluation of FHE operations to provide sIND-CPAD security.
This new feature is transparent to users.

Cleanup

Host and gateway contracts have been cleaned:

• Unused offset has been removed from the decrypted result in public decryption.
• Gateway check... functions have been replaced by non-reverting is... boolean getters.
• contractsChainId field have been removed from user decryption request EIP712 struct.
• New internal empty proxy contracts have been implemented.
• Two gateway contracts have been renamed.
