What it does
Polynomial Trade combines an order book and automated market-making liquidity for perpetual contracts on Polynomial Chain. Positions share account collateral. Its interface includes market, limit and conditional orders, with separate controls to add to or reduce an existing position.
Polynomial separates funding from order entry. Connect an EVM wallet, then use Deposit to select the sending chain, asset and amount through its official bridge. The wallet guide lists Ethereum, Arbitrum, Optimism and Base as funding routes.
On the trading page, choose the contract and direction. Enter the margin amount and multiplier, then compare the resulting position size, fees and liquidation price before selecting Long or Short. In Positions, select an existing trade to use Add to Position or Reduce Position. Those actions change an existing exposure rather than creating an unrelated wallet transfer.
The standard fee schedule lists 0.04% maker and 0.06% taker. BTC and ETH pairs are currently listed with zero trading fees, but funding and other applicable charges remain separate. Non-crypto pairs can incur rollover charges. Gasless trading on Polynomial Chain does not remove those costs or the costs of funding from another network.
All open positions use the account balance as shared collateral. Losses and liquidation risk therefore affect the portfolio, not just the margin notionally assigned to one trade. The terms exclude US persons, including citizens and residents, and require users to be at least 18 or the local age of majority.
