The promise
Nothing is sent until you confirm each step in your wallet.
What's listed
Every listing published through Seaport for a Valorem option, read from the chain.

Exercise any time before Friday 20:00 UTC: pay the strike and take what the writer locked.
What you wrote
Each claim is your receipt for what you locked. After Friday, redeem it for whatever it holds.
