The DFlow Prediction Market API is an onchain trading and tokenization layer for prediction markets. DFlow applies fees based on trading volume through the Prediction Markets API.

​
Fees

DFlow applies a fee to trades made through the DFlow Prediction Market API with the following fee coefficient schedule.

​
Fee Schedule

Tier30D VolumeTaker Fees ScaleMaker Fees Scale
Frost< $50M0.090.0225
Glacier$50-150M0.08750.021875
Steel$150-300M0.0850.02125
Obsidian> $300M0.080.02
The fee charged is calculated using the formula: scale * p * (1 - p) * c Where:
  • scale = fee coefficient from the tier table (taker or maker scale based on order type)
  • p = fill price
  • c = number of contracts traded
The fee schedule is based on 30-day trading volume on outcome tokens via the Prediction Markets API.

​
Rebate Program

Application partners will be eligible for the Prediction Market API Rebate Program, which will rebate partners the greater of:
  • (a) 3% rebate on gross applicable trading fees, or
  • (b) the marginal rebate rate from the schedule below
These rebates will be applied on an aggregate trading volume on outcome tokens basis across every application on Solana.

​
VIP Rebate Schedule

Tier30D VolumeIncremental Rebate
VIP 0< $50MNo incremental rebate
VIP 1$50-150M10% rebate on incremental trading fees
VIP 2$150-$300M20% rebate on incremental trading fees
VIP 3> $300M30% rebate on incremental trading fees
Only trading fees up to a taker scale coefficient of 0.07 and maker scale coefficient of 0.0175 count towards rebates.

​
Example

If all partners in aggregate trade $75M in outcome token volume in a month, they receive the greater of:
  • 3% on total applicable fees, or
  • The combined marginal rebate (10% on the $25M increment above $50M) pro rata based on how they contributed to the total rebate

​
Volume Tracking

Applications’ trading volume on outcome tokens is calculated by their API key. The volume refers specifically to outcome token trading volume via the Prediction Markets API.
Applications must use their API key for outcome token trading volume to be tracked correctly. Volume is calculated based on the API key used in requests to the Prediction Markets API. See the API Keys guide for information on obtaining and using API keys.
The 30-day volume thresholds used for fee tier determination and rebate eligibility are based on the aggregate trading volume across all applications using the Prediction Markets API on Solana.
