Settlement

How an option closes.

Pinned to the expiry round

Settlement is pinned to the round at expiry — the first round at or after the expiry timestamp, not an interpolated mid-price.

A call settles into the underlying stock at the strike; a put settles the other way. Collateral is full, and premium is paid in USDG.

This is a demonstration. Cadence does not claim mainnet deployment, and no feature here settles on-chain.
