Fees on SoDEX are determined by your rolling 14-day volume and are finalized at the end of each UTC day. Your fee tier applies across the platform and updates automatically.
How fee tiers are calculated
Rolling 14D volume: We look at your last 14 days of trading activity (rolling window).
Daily settlement (UTC): Your tier is re-evaluated once per day at the end of the UTC day.
One tier for all markets: Each user has a single fee tier that applies across all assets and markets.
Perps + Spot are combined
Your fee tier is based on combined perps and spot volume.
(14D weighted volume) = (14D perps volume) + 2 × (14D spot volume)How your final fee is determined
Your final fee depends on whether you are a taker or a maker:
Taker fees are always based on your 14D volume tier, with an optional staking discount: Taker fee = Base taker fee × (1 - Staking discount)
Maker fees work in two ways:
By default, same as taker: Maker fee = Base maker fee × (1 - Staking discount)
If your 14D maker volume share reaches a threshold, you qualify for Maker Rebates — a standalone negative fee rate where the platform pays you for providing liquidity. This replaces the volume-based maker fee.

Staking SOSO grants a fee discount applied to your volume-based fee. The discount updates at the end of each UTC day and applies automatically once active.
Effective fee = Base fee × (1 - Staking discount)

💡 Tip: When you initiate partial unstaking, despite the 14-day unstaking period, your fee discount will be instantly recalculated based only on your remaining staked SOSO.
If your 14D maker volume share reaches a threshold, you qualify for a negative fee rate — the platform pays you for providing liquidity.
Rebates are paid continuously on each trade directly to your trading wallet.
