Fee Details
The Diffused Dex fee system is structured into multiple tiers, each providing discounted trading fees based on the user’s holdings.
You can qualify for a tier using either:
- Your FUSE token balance (fungible token), or
- Your Forever Card NFT balance
Holding any one of these is enough to unlock the corresponding tier - you do not need both.
| Tier | FUSE token (Min Balance) | Forever Card (Min Balance) | Fee (%) | Min Fee (HBAR) |
|---|---|---|---|---|
| 0 | 0 | 0 | 0.400 | 5.000 |
| 1 | 10,000 | 1 | 0.375 | 4.500 |
| 2 | 25,000 | 10 | 0.325 | 4.000 |
| 3 | 50,000 | 25 | 0.275 | 3.500 |
| 4 | 100,000 | 50 | 0.200 | 3.000 |
How the Fee Tiers Work
Each tier provides:
- A reduced percentage fee
- A reduced minimum fee (charged when trade size is small)
You will automatically receive the highest tier you qualify for, depending on either your FUSE balance or your Forever Card NFT count.
Tier Qualification Examples
- If you hold 100,000 FUSE and 0 Forever Cards, you qualify for Tier 4.
- If you hold 25 Forever Cards but only 10,000 FUSE, you qualify for Tier 3.
- The system always checks both balances and applies the better tier.
Fee Calculation
Your fee is calculated as:
Final Fee = max(Trade Amount × Fee %, Minimum Fee)
If the calculated percentage fee is lower than the minimum, the minimum fee for that tier is charged instead.
Example:
If your fee calculation results in 2.1 HBAR, but your tier’s minimum fee is 3.0 HBAR,
→ You will be charged 3.0 HBAR.
Paying Fees in FUSE (Optional)
Users holding FUSE tokens have the option to pay their orderbook fees using FUSE instead of HBAR.
This provides added flexibility and may reduce effective trading costs depending on market conditions.
Summary
- Tiers are unlocked via either FUSE tokens or Forever Card NFTs.
- You always receive the best available tier based on your balances.
- Fees are calculated using percentage or minimum, whichever is higher.
- FUSE holders can optionally pay fees directly in FUSE.
