Trading Fees
Trading fee tiers and how you can get a rebate on your trading fees
Polysynth uses a 30-day tiered convergent-divergent volume-weighted fees model for determining the trading fees. There are two types of orders on Polysynth – Convergent and Divergent orders.
  • Convergent orders are orders which earn funding payments – these orders converge mark price to index price
  • Divergent orders are orders which pay funding payments – these orders diverge mark price from index price

Polysynth's Trading Fee Schedule
For the time being, Polysynth applies a flat trading fee of 0.07% on all trades.

Trading Fee Rebate

Holders of POL or sPOL (staked POL) receive a trading fee rebate based on the size of their current holdings:
Polysynth's Trading Fee Rebate Schedule
Trading fee rebates can be modified by the community via governance subject to a minimum base rate of 5 bps for divergent trades.
Divergent fees after all rebates and benefits cannot be lower than 0.05% (5 bps).
The following table shows the fee discount applied to the current volume weighted convergent-divergent fee schedule:


How are divergent and convergent fees calculated?

The divergent and convergent fees are based upon the total USD trading volume over the trailing 30-day period across all perpetual markets.

How do I know my order is a convergent order?

If you are going long on a perpetual contract and its mark price is less than the index price, your order is a convergent order and will earn funding payment. Similarly, if you go short on a perpetual contract whose mark price is greater than the index price, your order is a convergent order and will earn a funding payment.
