In Options Trading, How Does Settlement Finality Relate to the Risk of a Chain Fork?

Settlement finality is the guarantee that the exercise or expiration of an options contract is irreversible. A chain fork introduces the risk that the settlement transaction could be reversed or that the oracle price used for settlement is invalidated on one of the chains.

This uncertainty is unacceptable in options trading, which requires precise, non-disputable execution. Strong finality, which a high fork cost promotes, is necessary for trustless, on-chain options.
