What Fees Does Entropy Charge?
Entropy's published rate on its own HIP-3 markets, io:ANTH and io:SNDK, is 0.030% maker and 0.090% taker. Per Entropy's fee documentation: “Fees on HIP-3 markets are 2x the standard validator-operated perp rate. The protocol fee is split evenly between Hyperliquid and the deployer.” That base validator rate is 0.015% maker / 0.045% taker, so the 0.030%/0.090% figure is not something Entropy set independently; it is the multiplier every HIP-3 deployer inherits from Hyperliquid.
Base Rate Summary
- Published HIP-3 rate: 0.030% maker / 0.090% taker
- Effective rate today: about 0.0030% maker / 0.0090% taker, with Growth Mode active
- Applies to: io:ANTH and io:SNDK only, Entropy's own two markets
- Funding: peer-to-peer between traders; the exchange takes no fee on funding payments
That last point on scope matters. Entropy's frontend also displays 317 other markets deployed by trade.xyz, Paragon, HyENA, and Markets by Kinetiq. Their fee schedules are set by those deployers, not by Entropy, and this page covers Entropy's own two markets only.
Growth Mode: The Published Rate vs. What You Actually Pay
Growth Mode is a Hyperliquid HIP-3 setting. Entropy's docs state: “When growth mode is enabled on a market, all fees, rebates, and volume contribution scale by 0.1 (a 90% reduction).” Entropy enabled Growth Mode on both io:ANTH and io:SNDK on August 19, 2026, the day trading went live, and it has remained active since.
| Role | Hyperliquid Base Rate | HIP-3 Rate (2x) | With Growth Mode (×0.1) |
|---|---|---|---|
| Maker | 0.015% | 0.030% | 0.0030% |
| Taker | 0.045% | 0.090% | 0.0090% |
Source: Entropy fee documentation. Growth Mode status confirmed live on both markets as of August 26, 2026.
Entropy's own docs never state that 0.0090% effective taker figure directly; it only publishes the two multipliers. EntropyGuides calculated it and cross-checked it against on-chain volume: $66,194,725 of 24-hour notional on the io dex, multiplied by 0.009%, works out to about $5,958 in fees, against a $5,982 24-hour fee figure reported independently by DefiLlama for the same dex on the same day, a ratio of roughly 1.00x.
It is worth being precise about what that means. 0.030%/0.090% is the standard HIP-3 default every deployer runs, and trade.xyz also runs Growth Mode on its own fee schedule, per its published documentation. The honest claim is that Entropy is the cheapest venue in the HIP-3 cohort measured on August 26, 2026, not that its fees are structurally cheaper by design.
How Entropy's Fees Compare to Other HIP-3 Deployers
HIP-3 fees are set by Hyperliquid, not by the individual deployer. Every deployer on Hyperliquid inherits the same base schedule; the only levers a deployer controls are its fee-scale multiplier and whether Growth Mode is enabled. That makes “cheaper fees” a weak differentiator between deployers on paper, which is why the comparison below is about what each venue actually publishes and what is measured, not about design intent.
| Deployer | Published Rate | Growth Mode | Notes |
|---|---|---|---|
| Entropy (io) | 0.030% / 0.090% | Active, both markets | ~0.0090% taker measured, Aug 26 2026 |
| trade.xyz (xyz) | 0.030% / 0.090% | Active | Same HIP-3 default; largest deployer by volume |
| HyENA (hyna) | 0.0167% / 0.0500% | — | Publishes a different multiplier, not the standard 2x |
| Markets by Kinetiq (mkts) | Not published as a rate | — | Implied ~0.0369% from fee/volume data |
| Paragon (para) | Not published as a rate | — | Implied ~0.0175% from fee/volume data |
Implied rates are calculated from each deployer's reported 24-hour fees and notional volume, not from a published percentage. Figures reflect a snapshot on August 26, 2026, on a venue where every number moves daily; re-check before relying on them.
Volume Tiers and HYPE Staking Discounts
Entropy's docs state: “Volume tiers, staking discounts, and referral rebates apply on the same basis as all other Hyperliquid markets. Fee tier is computed across a user's combined 14-day weighted volume across spot, perps, and HIP-3 perps.” These are Hyperliquid-wide mechanisms, not perks specific to Entropy, and they apply identically whether you are trading io:ANTH or any other Hyperliquid market.
| 14-Day Volume | Perp Maker | Perp Taker |
|---|---|---|
| >$5M | 0.012% | 0.040% |
| >$25M | 0.008% | 0.035% |
| >$100M | 0.004% | 0.030% |
| >$500M | 0.000% | 0.028% |
| >$2B | 0.000% | 0.026% |
| >$7B | 0.000% | 0.024% |
| HYPE Staking Tier | HYPE Staked | Fee Discount |
|---|---|---|
| Wood | >10 | 5% |
| Bronze | >100 | 10% |
| Silver | >1,000 | 15% |
| Gold | >10,000 | 20% |
| Platinum | >100,000 | 30% |
| Diamond | >500,000 | 40% |

Non-Trading Fees: Deposits, Withdrawals, and Funding
Trading fees are only part of the cost of using Entropy. Getting USDC in and out through Hyperliquid's bridge, and the one-time cost of activating a Hyperliquid account, add up too.
| Item | Amount |
|---|---|
| Hyperliquid account activation (one-time, first outbound action) | $1.00 |
| Deposit, direct bridge | $0 |
| Deposit, Circle CCTP route | $0.20 flat |
| Arbitrum gas for bridging | ~$0.01 in ETH |
| Withdrawal, standard bridge | $1.00, $5 minimum, ~4 min to Arbitrum |
| Withdrawal, Circle CCTP route | ~$0.20, $5 minimum, ~1 min |
| Funding payments | Peer-to-peer; no exchange fee |

The Referral Rebate, and the Number You Need to Get Right
Entropy's referral program has three parts: a Self Rebate on your own fees, a Referral Reward paid when someone you referred trades, and a Referred-User Benefit that applies automatically to anyone who signs up through a link, including ours.
| Tier | Qualification | Self Rebate | Referral Reward | Referred-User Benefit |
|---|---|---|---|---|
| 1 – Trader | None | 60% | 25% | 25% |
| 2 – OG | One historical HIP-3 trade | 120% | 50% | 50% |
| 3 – Preferred | $10M rolling 30-day volume | 160% | 75% | 75% |
| 4 – Partner | $50M rolling 30-day volume | 200% | 100% | 100% |
Source: Entropy referral documentation.
Worth knowing exactly how those percentages are computed, because the base they apply to is not the number most people assume. Entropy's docs state that “all percentages are calculated against Entropy's share of the HIP-3 trading fee, not the trader's total trading fee.” Their own worked example: on $100 of total trading fees, roughly $50 goes to Hyperliquid and $50 to Entropy, so a 50% Self Rebate does not return $50, it returns 50% of Entropy's $50 share, or $25.
So at the entry tier a referred user gets back roughly 12.5% of what they actually pay, automatically, on every trade, for as long as the account trades. Against an effective taker fee already down at 0.0090%, that is the cheapest way into these markets we can measure. The one catch is timing: a code attaches only at signup and can never be added afterwards, so arriving without one means paying the full rate permanently.
Scope and mechanics worth knowing: the rebate applies only to activity on Entropy-deployed markets, io:ANTH and io:SNDK, not the 317 other markets aggregated on Entropy's frontend. It works regardless of which Hyperliquid frontend you trade through. Payouts are claimed manually from a dashboard and pass through a status ladder that includes a “Held” state controlled off-chain by Entropy, which is worth knowing before you count on a rebate as settled.
The Builder-Fee Approval
Trading on Entropy also requires signing a separate builder-fee approval during onboarding. As observed in Entropy's own front-end code, the approval a user signs authorizes a maximum builder fee rate of 1%, while the rate currently configured and charged is 0%. The word “builder” does not appear anywhere in Entropy's public docs, terms of service, privacy policy, or risk disclosure; it surfaces only as a button label during onboarding and inside the raw signature request. Nothing is currently being charged through this mechanism, but the signed approval would let Entropy begin charging up to that maximum without asking for a new signature. The full mechanics, including the exact numbers and the on-chain wallet used, are in our dedicated fees breakdown.
Frequently Asked Questions
Entropy publishes 0.030% maker and 0.090% taker on its HIP-3 markets, per Entropy's own fee documentation. That is double Hyperliquid's standard validator-operated perp rate of 0.015% maker and 0.045% taker, the multiplier every HIP-3 deployer carries. Growth Mode is currently active on both of Entropy's live markets, io:ANTH and io:SNDK, which scales fees down by 0.1, so the rate traders actually pay today is closer to 0.0030% maker and 0.0090% taker.
Growth Mode is a Hyperliquid HIP-3 setting that, when enabled on a market, scales all fees, rebates, and volume contribution by 0.1, a 90% reduction. Entropy enabled it on both io:ANTH and io:SNDK on August 19, 2026, the same day trading went live. Entropy's own docs state the setting exists but never publish the resulting effective rate directly; EntropyGuides calculated 0.0030% maker and 0.0090% taker from the published multipliers and cross-checked it against on-chain fee data.
It hands back roughly 12.5% of every fee you pay, automatically, on every trade, for as long as the account trades. The percentage applies to a smaller base than most people assume: Entropy calculates referral percentages against its own roughly 50% share of the HIP-3 fee. In Entropy's own worked example, $100 of total trading fees splits about $50 to Hyperliquid and $50 to Entropy, so the entry tier's 25% returns 25% of that $50 share, or $12.50. Against an effective taker fee already down at 0.0090%, that is the cheapest route into these markets we can measure. A code can only be attached at signup and never added later.
Hyperliquid charges a one-time $1.00 account activation fee on your first outbound action. Depositing USDC through the direct Arbitrum bridge is free; the Circle CCTP route costs a flat $0.20. Bridging also requires a small amount of Arbitrum gas, typically around $0.01 in ETH. Withdrawals cost $1.00 through the standard bridge, with a $5.00 minimum and roughly 4 minutes to Arbitrum, or about $0.20 through CCTP with the same $5.00 minimum and roughly 1 minute. Funding payments are peer-to-peer between traders; the exchange takes no fee on funding.
HIP-3 fees are set by Hyperliquid, not by the individual deployer, so the published 0.030%/0.090% schedule is the same one every deployer inherits, including trade.xyz. trade.xyz also runs Growth Mode, per its own fee documentation. Measured against on-chain fee and volume data on August 26, 2026, Entropy's all-in rate worked out to about 0.0091% taker, making it the cheapest measured rate in the HIP-3 cohort that day. That reflects the shared HIP-3 default and Growth Mode, not a fee structure unique to Entropy.
