Settlement

Markets resolve from three exchange price sources, followed by an on-chain review window.

Settlement process

1
Record the expiry price
Settle collects the closing price for the exact expiry minute from Coinbase, Kraken, and Binance.
2
Check source agreement
At least two sources must agree within 0.5%. The median of the agreeing prices becomes the settlement price.
3
Propose the outcome
An automated service called the keeper submits the result on-chain.
4
Finalize and claim
After the review window, anyone can finalize the market. Winners can then claim from Portfolio.
