Ensuring Secure and Efficient Cross-Chain Option Transfers | HackerNoon
Briefly

Protocol 4.2.1 ensures that in any compliant transfer scenario, parties retain their entitled positions and collateral, maintaining safety throughout the asset exchange process.
The safety property ensures that a compliant party will never lose their collateral without receiving appropriate compensation, reinforcing the integrity of the option transfer system.
