QIC-AMM which short for Quoted Index price and Constant integral based Automated Market Maker.

  • YFX's price index is calculated using a weighted average of last Prices from coinbase. binance, kraken, bitstamp, huobi and oec.
  • QIC-AMM would automatically remove deviation value of mistake price.
  • QIC-AMM use constant integral to calculate depth of Market Maker Pool and use normal distribution on liquidity provider for depth of Market Maker Pool, X~N(indexprice, σ2)

Each trading pair has a market maker pool, and users' trades and P&L are settled with the market maker pool.

All trades would be made with the Market Maker Pool. For each trading pair, there is a Market Maker Pool, orders are settled in Market Maker Pool. As market maker, you only need to staking one type of token to Market Maker Pool, redeem your fund in Market Maker Pool at anytime you want.

YFX solved system liquidation issue.

In YFX, market maker use a different leverage as traders. In a normal situation, market maker would use 1/5 leverage when a trader trade with QIC-AMM. For example, when a trader open a position of 100 USDT, 10x leverage long position, QIC-AMM will use 2x leverage, in this case 500 USDT will be frozen in market maker's account.

Both traders and market maker have a loss and profit cap with in the case of liquidation, the trading platform won't afford any loss from market swing and protect all assets in our smart contract.

  • This mechanism can prevent losing traders drop below zero.
  • This mechanism can avoid trading failure caused by block time delay and other uncertainly issues.

Q & A

  • Trader and Market Maker

    You can choose Trader and/or Market Maker to start your journey at YFX. As a trader use your experience and try your luck to appreciate your asset. As a market maker, your role is to provide liquidity and earn a part of transaction fee and trading profit from QIC-AMM.

  • On-chain price oracle are less efficiency caused by delay and uncertainty of blockchain. Because current blockchain tech can't meet trading requirement, we used a centralized QIC price quotation system for now. QIC price is based on the latest price trade on the several large crypto exchanges. Anyone could verify YFX's price index.

  • User's maximum position is correlated to Market Maker Pool fund.

  • Market makers pool = frozen amount + unused fund + unrealized P&L. Currently, for up to 60% of fund in Market makers pool would be use for margin, these fund would be locked by smart contract when user trade with market maker pool. The rest fund(40%) are provide liquidity for Market makers pool. In case there is not enough fund for liquidation use, user need to wait until a margin unfreeze.

  • Currently YFX charge a 0.05% for open and close a position and 0.1% fee on redemption from Market Maker Pool.

  • For the current version, there's no funding fee on YFX. To balance the trading system, we design that everyone could only hold one position for up to 1 million block time on TRON, BSC and Heco, for Ethereum it will be 200,000 block which is around 30 days.
