How Settle works

Settle matches signed orders off-chain and settles fills through an on-chain hub contract.

One market, two outcomes

Every market asks one question: will an asset’s price be at or above a stated target when the market closes?

AboveYES

The final price meets or exceeds the target.

BelowNO

The final price is lower than the target.

Shares trade from 1–99¢. The quoted price expresses implied probability: 62¢ means the market estimates a 62% chance of Above.

From order to settlement

01Your wallet

Signs an EIP-712 order locally.

02Matching engine

Finds compatible orders off-chain.

03Hub contract

Verifies and settles each matched fill.

Off-chain matching keeps order placement responsive. On-chain verification makes the signed price, quantity, expiry, and account authorization enforceable.

Custody and permissions

Funds and positions live in the SettleMarkets hub contract. The operator can match compatible signed orders, but cannot fill an order at a price you did not approve or withdraw your balance.

  • Orders are authorized by wallet signatures.
  • Matched fills are verified on-chain.
  • Withdrawals return funds to the balance owner.
  • Available funds remain withdrawable if the exchange is paused.
