Intention charges maker and taker fees per fill. Fees are determined by your 14-day rolling volume tier, with separate schedules for perpetuals and spot. Exceptional market makers earn additional rebates, and all trading fees flow back to community infrastructure — the liquidity vault, insurance fund, and listing deployers — rather than to a corporate treasury.
Volume tiers
Your tier is derived from a weighted 14-day rolling volume, where spot counts double:
14d weighted volume = 14d perps volume + 2 × 14d spot volume
| Tier | 14-day volume | Perp taker | Perp maker |
|---|
| 0 | — | 0.0450% | 0.0150% |
| 1 | > $5M | 0.0400% | 0.0120% |
| 2 | > $25M | 0.0350% | 0.0080% |
| 3 | > $100M | 0.0300% | 0.0040% |
| 4 | > $500M | 0.0280% | 0.0000% |
| 5 | > $2B | 0.0260% | 0.0000% |
| 6 | > $7B | 0.0240% | 0.0000% |
Market maker rebates
Market makers whose 14-day maker volume exceeds a fixed share of total platform maker volume earn an additional rebate on top of their tier:
| Share of total maker volume | Extra maker rebate |
|---|
| > 0.5% | -0.001% |
| > 1.5% | -0.002% |
| > 3.0% | -0.003% |
Rebates are credited as negative fees at fill time and show up as positive balance deltas in your fee account.
Contract groups
Contracts are grouped into six tiers by liquidity profile, and each group can carry its own schedule:
- Group 1 (Majors) — BTC, ETH, SOL, XRP. Tightest spreads, lowest taker fees, institutional maker rebates.
- Group 2 (High growth) — Large caps with strong depth.
- Group 3 (Mid-tier liquidity) — Mid caps with steady flow.
- Group 4 (Mid-tier activation) — Growing liquidity, modestly higher takers.
- Group 5 (Long tail) — Lower liquidity; new USDT perps list here by default.
- Group 6 (Pre-market + Innovation Zone) — Highest risk, pre-market listings.
Group assignments and rates are reviewed monthly.
Where fees go
Trading fees are credited to a protocol-controlled fee account and periodically distributed:
- Liquidity (HLP / liquidation vault) rewards
- Insurance fund top-ups
- Spot token deployers (up to 50% of fees on their listings)
- Referral rebates
The insurance fund and fee account are fully on-chain. Movements from the insurance fund require a validator quorum.
Special accounts
Negotiated rates may apply to select partners. Unless a special agreement is in place, everyone trades on the same public schedule.
Fee values shown above are the pre-launch schedule and may be re-tuned before mainnet. The schedule will remain configurable on-chain after launch via governance.
