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:
The tier is recomputed in the first block after each UTC midnight and applied to all sub-accounts under a master account. New accounts start at tier 0. Spot fees follow a similar ladder, starting at 7 bps taker / 4 bps maker at tier 0 and reaching 3 bps taker / 0 bps maker at the top.

​
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:
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.
