USDC -- all trades are funded and settled in USDC. You can obtain USDC at any major exchange, such as Uniswap.
Courage -- trade at your own risk! Financial loss is possible, although you will never lose more than your initial investment.
These steps allow you to trade on Perpetual Protocol with zero gas fees, thanks to the xDai network, while also using your regular Ethereum wallet to trade, with no set-up needed.
The deposit step moves your USDC to the xDai network using the xDai Omni Bridge. The funds remain in your wallet and are visible if you add the xDai RPC as well as the xUSDC custom token. You can perform this deposit step manually using Omni Bridge, if desired.
Note that you must cover the gas costs while using Omni Bridge to deposit.
Approval Step 1: Approve the Omni Bridge smart contract to use your USDC Deposit: The Omni Bridge smart contract locks the USDC and mints xUSDC Approval Step 2: Approve your funds for trading on the Perpetual Protocol smart contract (same as when trading tokens on Uniswap, etc.)
The withdraw step moves your xUSDC back to Ethereum, where it will appear in your wallet as USDC. The process is again completed using the xDai Omni Bridge and can be performed manually by the user at any time.
Note that the Omni Bridge pays gas for withdrawals, but also charges a 0.05% exit fee.
Approval Step 1: Approve the Omni Bridge smart contract to use your xUSDC Approval Step 2: Approve the Omni Bridge smart contract to burn the xUSDC and release USDC back to your wallet
All trades are processed using the xDai Chain, an Ethereum side chain. xDai is a proof of authority chain with 5 second block times and incredibly low gas fees (on the order of 0.0005 DAI per tx), so currently these fees are paid for by Perpetual Protocol.
This is not possible yet due to the nature of the AMM model. It is not possible to guarantee the final size of your position after the request is made. E.g. if you have a 1000 USD position and give an order to reduce it to 500 USD, other trades in the same block could cause your final position to be above or below your 500 USD target.
To change your position size, either open a new buy or sell order. The new position will be merged with the active (existing) position.
If you have insufficient collateral, you can remove margin from your active position(s) using Margin Mgt. (thereby increasing your leverage).
USDC was chosen as the base asset thanks to its popularity throughout the DeFi space.
It is possible to let users trade using other assets, such as BTC or ETH, as collateral, but we do not plan to add this feature in the short term. It may be added via governance in the future.
A keeper (bot) triggers funding at the beginning of each hour.
Deep dive The Perpetual Protocol smart contract will allow anyone to trigger funding after the top of the hour. Once funding has been triggered, it cannot be triggered again until the next hour. In addition, funding cannot be triggered until 30 minutes have elapsed since the previous trigger. E.g. if funding is not triggered at 3:00, and then triggered at 3:35, the next funding will not be allowed to trigger before 4:05.
Funding payments are shown as positive numbers when you made a funding payment (debit), and negative numbers when you received a payment (credit).
See your position history including funding payments in Position History at the top of the trading interface:
Funding payments will increase or decrease the margin of the respective position each time the funding cycle ends.
0.1% Transaction Fees
50% of the transaction fees will be deposited into the Insurance Fund to cover unexpected losses resulting during trading on Perpetual Protocol. The remaining transaction fees are shared with stakers based on their contribution to the Staking Pool.
Traders are also eligible for fee refunds and other benefits. Read more here.
Fees and fee allocation can be adjusted through governance to keep the protocol competitive in the market.

Currently Perpetual Protocol has 2 types of caps:
Personal Position Cap
This is the maximum position size you can open for any individual asset traded on Perpetual Protocol. This includes long and short positions.
For example, the maximum position size for ETH might be 200 ETH (this is just an example - the real number will be bigger.)
Open Interest Cap
Open Interest refers to the value of all open positions, long or short, in aggregate. This total value has an upper maximum limit.
For example, if all the BTC long positions are worth 5 million USDC in total, and all short positions are worth 2 million USDC in total, the open interest is 7 million USDC.
Go to perp.exchange and enter a large number for the asset you wish to check. The interface will give you a warning, as well as show the current maximum size you can trade.
Note there is no easy way to check the open interest cap at this time. The team monitors open interest and increases the cap as needed, according to market conditions.
Caps help keep traders on Perpetual Protocol safe. A sudden, dramatic increase in open interest may be the result of an exploit or attack. Personal caps increase the friction for those attempting an exploit, forcing them to manage an attack across several wallets, while at the same time being of relatively little hindrance to regular traders.
Having caps helps limit the effect and scale of attacks, reducing the profit for attackers. Caps also help mitigate the possibility of price manipulation exploits.
