Frequently Asked Questions
about Ostium App

Click the "Log In" button in the top right corner of the Ostium App interface. You can connect using a browser wallet such as MetaMask or Rabby, or via social login options powered by Privy.

Make sure your wallet is set to the Arbitrum network. If you are on the wrong network, Ostium App will prompt you to switch automatically.

To trade on Ostium App you will need:

1. A compatible Web3 wallet (MetaMask, Rabby, Coinbase Wallet, etc.)
2. USDC on Arbitrum to use as collateral
3. A small amount of ETH on Arbitrum to cover gas fees

Once your wallet is funded, you can deposit USDC, select a market, and open your first position directly from the Ostium App trading interface.

Ostium App offers perpetual markets across six distinct asset classes:

Commodities: Gold (XAU), Silver, Brent Crude, WTI Oil (CL)
Crypto: BTC/USD, ETH/USD, and more
Forex: EUR/USD, USD/JPY, GBP/USD, and major pairs
Indices: US100 (Nasdaq), SPX (S&P 500), and others
Stocks: Selected individual equity perpetuals
ETFs: Popular ETF perpetual markets

Leverage on Ostium App allows you to open a position larger than your deposited collateral. For example, with 10x leverage and $100 USDC collateral, you control a $1,000 position.

While leverage magnifies potential profits, it also magnifies potential losses. If your position moves against you and your collateral falls below the required maintenance margin, your position may be liquidated to protect the liquidity pool. Always use appropriate risk management when trading with leverage on Ostium App.

Unrealized PNL is the current profit or loss of your open positions based on the current market price versus your entry price. It fluctuates continuously as prices move.

Realized PNL is the profit or loss that has been locked in after you close a position. You can track both on the Ostium App Portfolio page along with your full trading history and performance metrics.

Ostium App uses decentralized oracle price feeds to source accurate, real-time prices for all markets. These oracles aggregate prices from multiple sources to produce a reliable, manipulation-resistant reference price.

This ensures that traders on Ostium App receive fair, market-aligned execution prices for every trade, whether they are going long or short on crypto, forex, commodities, indices, or equities.

The Ostium App Vault is a USDC liquidity pool that acts as the counterparty to all trades on the platform. When you deposit USDC into the vault, you receive OLP tokens representing your share of the pool.

As a liquidity provider, you earn a portion of the trading fees generated by all activity on Ostium App. The value of your OLP position increases as the vault accumulates fees from traders.

Yes. As a liquidity provider in the Ostium App Vault, your OLP position takes the opposite side of all open trades. This means if traders on Ostium App are collectively profitable, the vault (and your OLP value) may decrease.

Conversely, when traders lose, the vault gains. Over time, the fee income from trading activity is designed to compensate liquidity providers for this risk. There may also be lock-up periods on vault deposits.

Ostium App Points are earned by trading on the platform. The more volume you generate, the more points you accumulate. Points can be boosted by participating in special promotions — for example, trading specific markets during a 2x boost period.

Check the Points page on Ostium App regularly to see active boosts, your personal leaderboard ranking, and how to maximize your points earnings. Points may be redeemable for future rewards as the Ostium App ecosystem grows.

Ostium App charges an opening fee and a closing fee calculated as a percentage of your notional position size. These fees are collected at the time you open and close trades and are distributed to OLP liquidity providers.

In addition to trading fees, open positions may accrue borrowing fees over time, and funding payments may be exchanged between longs and shorts depending on market conditions. All fee details are displayed transparently in the Ostium App trading interface before you confirm any trade.

Funding rates on Ostium App are periodic payments between long and short traders that keep the perpetual contract price tethered to the underlying asset's market price. When there is a large imbalance of longs versus shorts, the dominant side pays funding to the minority side.

This mechanism is standard across all perpetual exchanges and ensures that Ostium App's perpetual prices remain in line with real-world prices over time. Your current funding rate exposure is shown in your open position details.

Ostium App's smart contracts are designed with security as a priority. The protocol has undergone security reviews to identify and mitigate potential vulnerabilities before deployment.

As with all DeFi protocols, smart contract risk can never be fully eliminated. We encourage users to review the Ostium App documentation, start with smaller position sizes while familiarizing themselves with the platform, and never trade with funds they cannot afford to lose.

Ostium App is deployed on Arbitrum, an Ethereum Layer 2 scaling solution. Arbitrum offers the security guarantees of the Ethereum mainnet while providing significantly faster transaction finality and much lower gas costs.

This makes Ostium App accessible and cost-effective for frequent traders who want to open, manage, and close positions without being deterred by high Ethereum mainnet fees.

To withdraw trading collateral from Ostium App, close your open positions to convert them back to available USDC balance, then initiate a withdrawal to your wallet from the Portfolio page.

For vault liquidity, redeem your OLP tokens for USDC through the Vault page. Redemption is subject to any applicable lock-up periods or cooldown windows. All withdrawals from Ostium App are processed on-chain directly to your connected wallet.
