Eterna vs Hyperliquid: fees, custody and AI agents
Both are self-custody perp venues with no KYC. They differ in where liquidity comes from, how fees scale, and how much of the product is built for automated agents. Below is a straight comparison — including the places Hyperliquid still wins.
| Dimension | Eterna Hybrid Exchange | Hyperliquid |
|---|---|---|
| Fee structure | Flat 0.014% maker / 0.035% taker, no tiers Simple | Tiered by 14-day volume: taker 0.045% → 0.024%, maker 0.015% → 0% |
| Fees for small accounts | Same flat rate from the first fill Cheaper | Base tier is the most expensive tier |
| Fees at very high volume | No further improvement — flat forever | Top tiers plus maker rebates can undercut Eterna Cheaper |
| Maker rebates | Not offered | Yes — rebates for the largest makers, so effective maker cost can go negative Advantage |
| Staking discounts | Staking tiers affect referral rates, not a published trading-fee discount ladder | Wood 5% → Diamond 40% off trading fees Advantage |
| KYC | None — wallet signature No KYC | None — wallet signature No KYC |
| Custody | Self-custody collateral | Self-custody collateral |
| Liquidity source | Hybrid: CEX-grade depth routed from Bybit's books, <200ms latency, 200+ perps, $10B+ daily volume | Fully on-chain order book on its own L1 — transparent, verifiable, deep in majors On-chain |
| Transparency of matching | Off-chain matching via the routed venue | Every order and fill is on-chain and auditable Advantage |
| Chart signals | Core product surface — signals sit on the trading chart Built in | Not a native feature; traders bring external tooling |
| Copy trading | Native Built in | Not native; third-party vaults and copy services exist |
| Quests / gamification | Quests and arcade mode Built in | Points and campaign programmes historically, not a quest system |
| AI agent support | Native MCP server, CLI, 29-method TypeScript SDK, instant isolated sub-accounts, Argon2-hashed keys, no withdrawal permissions Native | Well-documented REST/WebSocket API with a large ecosystem of community SDKs and bots — powerful but ad-hoc for agents |
| Bot ecosystem maturity | New — fewer battle-tested open-source stacks | Large, mature, heavily forked bot ecosystem Advantage |
| Best for | Retail and mid-size traders, signal-driven discretionary traders, AI-agent builders | Order-book-dependent strategies, market makers, teams with an existing HL stack |
Where the fee crossover happens
Eterna's flat schedule beats Hyperliquid's base and mid tiers for a typical 30% maker / 70% taker mix. At the illustrative case of $1M monthly volume with no staking discount, Eterna charges about $287 a month against roughly $360 on Hyperliquid's base tier — a ~20% saving. As Hyperliquid volume tiers kick in (and especially once staking discounts and maker rebates apply), that gap narrows and eventually flips.
Rather than trusting a single example, put your own volume, split and staking tier into the Eterna vs Hyperliquid fee calculator — it shows the monthly and annual difference and names the winner at your inputs.
Under ~$5M/month
Eterna's flat rate is usually clearly cheaper, because Hyperliquid's base tier is its worst pricing.
$25M–$100M/month
The gap tightens fast. A Gold or Platinum staking discount can put Hyperliquid ahead, especially with a maker-heavy mix.
Market-maker scale
Hyperliquid wins on cost: near-zero maker fees plus rebates for top makers are something a flat schedule cannot match.
Honest verdict
Stay on Hyperliquid if your edge depends on its order book or you run a battle-tested HL bot stack. Try Eterna if you want flat low fees, signals, quests, and native AI-agent workflows.
There is no need to pick one permanently. Most traders who switch keep both accounts: Hyperliquid for strategies tied to its on-chain book, Eterna for cheaper discretionary flow, signal-driven trades and agent experiments.
