Perpetual Contracts

As of now, users can trade the following perpetual contracts on YFX. YFX will add more contracts in the near future.

*BTC_USD and ETH_USD markets will share a USDC pool (USDC1 Pool), and ARB_USD market will use a USDC pool (USDC2 Pool) alone.


YFX V3 only supports USDC tokens officially released by Circle, not USDC.e tokens of the Arbitrum cross-chain bridge.

USDC contract address: 0xaf88d065e77c8cC2239327C5EDb3A432268e5831

Users can buy USDC tokens officially released by Circle at centralized exchanges like Binance, Bybit, and Kraken or swap tokens at DEXs like Uniswap.


YFX V3 introduces a new referral program that allows invitees to enjoy a transaction fee discount and inviters to earn transaction fee rebates whenever invitees trade on YFX. The maximum rebate rate is 30%, while the maximum discount rate is 10%.

The transaction fee rebate is credited to the inviter’s wallet in real time after each invitee’s transaction is confirmed on the chain. The inviter can get 1 URP token (Referrals Proof) for every 1 USD traded by the invitees. There are five tiers of transaction fee rebates and discounts. When the inviter’s URP accumulates to a certain amount, users can burn all URP tokens and move up a tier level.

YFX provides an additional business affiliate program for KOLs, community leaders, media organizations, and data navigation websites. If you are interested, please contact us at contact@yfx.com. Our team will get in touch with you soon.


The new Earn system will be introduced very soon. It will allow users to stake YFX, YLP, or other tokens to earn YFX tokens and transaction fees in ETH / WETH as rewards. Follow our official Twitter account and join our Telegram channel for the latest update on YFX Earn.
