Polynomial Review: What Happened to the Perps Exchange?

Polynomial was a decentralised perpetuals exchange built on its own Ethereum rollup, rather than a general-purpose spot exchange. Its site described more than 40 perpetual markets, including BTC and ETH, with advertised leverage up to 50x. It promoted cross-margin, meaning collateral could support multiple positions in one account, and said users could use ETH, stablecoins and other assets as margin.

The exchange described two execution modes: pool-based trading for newer markets and an orderbook as markets matured. It also claimed oracle-based liquidations and gas-free trading through smart wallets. These are descriptions of the product it aimed to offer, not evidence that these features remain usable. Polynomial ceased operations starting February 14, 2026. If you are considering it as a place to trade now, the practical answer is no: don’t rely on its product page or connect a wallet expecting an active market.

Polynomial does not publish specific trading fee rates in the product details. Its documentation search listing describes a funding model called Funding Rate Velocity, but the actual funding charges, fee schedule and other costs are not established here. Perpetuals can incur trading fees and funding payments, and leverage magnifies the effect of price moves on your collateral; you would need clear, current terms before opening any position.

The site said that 50% of protocol fees would go to stakers. That is a description of the protocol’s proposed fee distribution, not a promise of a particular staking return or a discount on trading costs. It also does not establish what fees were actually collected or paid. With operations ceased, there is no sound basis to assume the advertised economics are still functioning. Don’t stake or send funds based on a displayed yield or fee-sharing claim without independently confirming that the relevant contracts and withdrawal paths remain active.

Polynomial’s site names 0xMacro and Octane as auditors and describes its architecture as transparent and open source. Those claims are useful starting points, but auditor names alone do not tell you which contracts were reviewed, when the work was done, or whether findings were fixed. The product details do not establish a licence, insurance, or a complete custody arrangement. A decentralised exchange can still involve smart-contract, oracle, bridge and liquidation risks; using a smart wallet does not remove them.

The most important current risk is operational: Polynomial ceased operations starting February 14, 2026. That makes old instructions and promotional claims especially poor evidence that deposits, staking or withdrawals will work today. If you have assets or an open position associated with Polynomial, do not assume funds are recoverable or that a displayed interface is current. Verify the exact contract and network involved, and seek current, project-specific confirmation before signing transactions. Never share your seed phrase or approve an unfamiliar transaction to “unlock” a withdrawal.

Polynomial said it ran on its own Ethereum rollup, built with the OP Stack. Developer documentation identifies the mainnet as Chain ID 8008. The product promoted smart-wallet account abstraction and gas-free trading, while its ecosystem page named Pyth for oracles and Socket for interoperability. These features were intended to make trading and moving assets easier, but they do not establish that the chain, bridge or trading interface is currently operating.

For a live rollup, you would normally need to select the correct network, fund an account through supported routes, and account for bridge and transaction risks. Polynomial’s shutdown changes that decision: don’t add the network or bridge assets simply because an old guide tells you to. Confirm that the chain and any relevant contracts are live and that a withdrawal route works before interacting. Current mobile support, transaction speed and support response times are not established, and advertised gas-free trading should not be read as proof that every action or exit is cost-free.

Polynomial is not a sensible choice for a new trade or stake: it ceased operations starting February 14, 2026. The product’s own promotional claims—such as deep liquidity, minimal slippage, 50x leverage and gas-free trading—do not establish current performance or availability. Even before the shutdown, key decision details such as exact trading fees and funding rates were not published in the product information, making it difficult to compare the full cost of using the exchange.

If you are checking an old position, distinguish between the exchange interface and the underlying on-chain contracts. A website being accessible does not prove that markets are active, a position can be safely closed, or collateral can be withdrawn. Confirm the exact network, contract addresses and current transaction status through reliable project documentation and on-chain records, and take care not to approve transactions from lookalike sites. Online derivatives trading is high risk; choose an operating venue only after checking its legal availability where you live, its fees, custody model and withdrawal process.
