SoDEX Dynamic Fee Tiers Are Now Live

To further improve trading efficiency and optimize the experience for active traders, professional market makers, and long-term ecosystem participants, the SoDEX Dynamic Fee Tiers are now officially live.This launch includes:

• Dynamic Fee Tiers
• Maker Rebate Tiers

• SOSO Staking Fee Discount Tiers

Through a more refined fee structure, SoDEX aims to provide a more competitive trading environment for different types of users based on their trading activity, liquidity contribution, and ecosystem participation.Perps + Spot are combinedYour 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 determinedYour 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.

Dynamic Fee Tiers

SoDEX will automatically assign users to the corresponding fee tier based on their rolling 14-day trading volume (14D Volume).The higher the trading volume, the lower the trading fee.The current fee tiers are as follows:

Tier	14D Volume	Perps Taker	Perps Maker	Spot Taker	Spot Maker
0	≤ $5,000,000	0.04%	0.012%	0.065%	0.035%
1	> $5,000,000	0.036%	0.01%	0.055%	0.025%
2	> $25,000,000	0.032%	0.006%	0.045%	0.015%
3	> $100,000,000	0.028%	0.002%	0.035%	0.005%
4	> $500,000,000	0.026%	0.00%	0.03%	0.00%
5	> $2,000,000,000	0.024%	0.00%	0.025%	0.00%
6	> $7,000,000,000	0.022%	0.00%	0.02%	0.00%

Maker Rebate Tiers

2	> 1.50%	-0.002%
3	> 3.00%	-0.003%

• Users who meet the threshold will receive the corresponding additional maker rebate
• This mechanism is designed to encourage deeper order book liquidity and more consistent market making activity
