Entropy’s fee program is designed around three separate benefits:

Self Rebate

A rebate on the trading fees generated by your own account. Your Self Rebate rate increases as your account moves up through the trading tiers.

Referral Reward

A reward paid to you when a user who joined through your referral link generates trading fees.

Referred-user Benefit

An automatic fee benefit given to users who sign up and trade through someone else’s referral link.

In simple terms, when a referred user trades, both the trader and the referrer can receive benefits.

Tier Structure

Tier Rolling 30-Day Volume Self Rebate Referral Reward Referred-user Benefit
Tier 1 Base Tier 20% 5% 5%
Tier 2 $1M+ 30% 12.5% 12.5%
Tier 3 $3M+ 50% 12.5% 12.5%

The percentages above are calculated based on Entropy’s share of the HIP-3 trading fee, rather than the trader’s total trading fee.

How the Fee Structure Works

For a simplified example, assume a trader generates $100 in total trading fees.

Under the HIP-3 fee structure, approximately:

$50 → Hyperliquid

$50 → Entropy

Entropy’s rebate and referral percentages are then calculated against Entropy’s $50 share.

This means, for example, a 50% Self Rebate does not mean that 50% of the entire $100 fee is returned. It means that 50% of Entropy’s $50 share is rebated.

Example 1: Tier 1 Trader

Assume a Tier 1 trader generates $100 in total trading fees.
