# Perpetuals ReHold offers decentralized [Perpetual](https://app.rehold.io) exchange with x100 leverage and multichain account balance. ### Multichain account balance Deposit and withdraw your crypto collaterals on all supported chains and trade the total balance of your assets. ### Isolated Margin Trading When you open a position a part of your balance will be collateral for the trade and your risk is limited by the amount of this collateral. You can create as many positions as you want and the results of your positions will be separated. ### Real-time prices ReHold uses aggregated price sources to provide the real market price for trading. The mid-price is the median of Binance, OKX, and Bybit perpetuals mid-price. Bid and ask prices are used for the opening/closing positions, and for calculating liquidation price. ### Gas-free transactions Opening and closing positions are gas-free for any started chain. Only deposit and withdrawal transactions are required by the gas costs. Our smart contracts are optimized for gas fees for in/out transactions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
