Eterna’s “0% fees”, explained without the hype
Eterna markets itself on “0% fees”. That phrase is doing a lot of work. Fees are charged on every trade — then their value comes back to you as in-app EHX. Here is the mechanism, the fine print, and an honest read on what it is actually worth.

What Eterna actually means by 0% fees
Eterna is explicit about this in its own documentation, and it is worth quoting the distinction directly. The company states that “0% fees” does not mean that no fee is charged at the moment of execution. It means exchange and platform trading fees are paid normally, in USDT, and then returned to you as EHX through an in-app payback system.1
The loop has three steps:
- You open, update or close a position. Standard trading fees apply and are charged in USDT.
- Eterna calculates the value of the eligible fee.
- After settlement, that value is credited to your account as EHX rewards inside the application.1
Eterna summarises it as: pay your fee, get your fee back in EHX. Win or lose, earn EHX.1
The four things EHX Payback is not
Eterna states this plainly, and any site telling you otherwise is misleading you. EHX payback is not a USDT refund, not a cash rebate, and not a withdrawal-ready token balance. It should not be described as immediately withdrawable, immediately stakeable, or the same as an on-chain EHX balance held in a wallet.1
The internal ledger rate
This is the detail that determines whether the payback is worth anything, and it is the detail most affiliate pages omit. In the current MVP model, EHX is credited at a fixed internal ledger rate of 0.0392 USDT per EHX. Eterna describes this as an internal reward calculation — explicitly not a live-market cash rebate and not a guarantee of EHX market value.1
Read that carefully. Your fee is debited at real market value in USDT. Your credit arrives in a unit valued by an internal accounting rate. Those two numbers only converge if EHX trades at or above the internal rate when you are eventually able to realise it. That is a genuine open variable, not a rounding detail, and it is the honest reason to treat the payback as an upside rather than as a fee waiver you can bank on.
What triggers a credit
The payback tracks activity at the fee-transaction level rather than at the final position level. If a position is closed in several parts, each fee event can generate its own EHX credit.1
It also extends past manual trading. Eligible trades executed through the Agents Marketplace follow the same fee reward logic, including copied trades from listed agents and AI-driven agents where available. The copied trade executes, the fee is charged in USDT, and the eligible fee value comes back as EHX.1
Crucially, the reward is calculated on fees, not on profit. Whether the trade closes green or red does not change the credit — if an eligible trade generates a fee and the conditions are met, the EHX is credited.1 Eterna is careful to note this is not a guarantee of profit, does not remove market risk, and does not change the outcome of a trade.1
A worked example
Eterna lists flat futures fees of 0.014% maker and 0.035% taker, with no volume tiers.2 Take a month of $500,000 in notional volume, split 30% maker and 70% taker:
| Line | Calculation | Amount |
|---|---|---|
| Maker fees | $150,000 × 0.014% | $21.00 |
| Taker fees | $350,000 × 0.035% | $122.50 |
| USDT actually debited | — | $143.50 |
| EHX credited in-app | $143.50 ÷ 0.0392 USDT per EHX | ≈ 3,661 EHX |
Fee rates per Eterna’s AI and infrastructure page; ledger rate per Eterna’s EHX payback documentation. Illustrative arithmetic, not a projection. The USDT figure is a real cost incurred; the EHX figure is an internal credit whose realisable value is not guaranteed.
EHX payback is not EHX staking
These are two separate systems and they get conflated constantly. Payback rewards your own trading fees with in-app EHX. Separately, Eterna documents an EHX staking mechanism where 50% of profits are distributed to EHX stakers, with profits generated by exchange fees, listing fees and taxes, and 3% of every transaction deposited into the staking pool.3
There is a third system again: referral rewards, which pay the referrer a USDT commission from the platform fee share, based on the trading activity of referred users. Eterna keeps these deliberately distinct — payback is tied to your fees, referrals to someone else’s.1
The honest verdict
Strip the marketing and two things are true at once.
What genuinely stands up
The headline fee rates are competitive before any payback is counted — 0.014% / 0.035% flat beats Hyperliquid’s base tier of 0.015% maker and 0.045% taker with no volume threshold to clear.24 The payback extends to copy trading and agent execution, which is unusual. And it is fee-based, so it pays out in losing months too.1
What to discount
“0% fees” is a description of a reward loop, not a fee schedule. The credit is virtual, in-app, valued at a fixed internal rate, and not immediately withdrawable or stakeable.1 Treat the flat rates as the real reason to use the venue and the EHX as a call option on the platform’s growth.
If you evaluate Eterna purely on the USDT that leaves your account, it still compares well. That is the sturdier argument, and it is the one this site leads with. Run your own numbers in the fee calculator, or see the full four-venue comparison.
Sign up with the referral code
Eterna’s referral commission is paid to the referrer out of Eterna’s own fee share. It is never added to your trading cost, and there is no separate signup bonus for the person joining — if you see one advertised, it is invented. Link: ehx.app/r/Steve.
