Infinex Integrates Hyperliquid: 2026 Review
Infinex is an onchain account-abstraction front end led by Synthetix founder Kain Warwick. Its goal is to give users a single place to manage cross-chain assets without constantly jumping between dApps. After Infinex added support for Hyperliquid perpetuals in late 2025, many traders started asking the same question: is this setup actually worth using?
This 2026 review looks at Infinex + Hyperliquid across four areas: account design, trading workflow, fees, and security assumptions. We’ll also compare it with a more direct workflow for perps traders using OneKey Perps.
Key comparison table
What is Infinex?
Infinex positions itself as an “onchain brokerage interface.” Under the hood, it uses EIP-4337 account abstraction to support keyless-style signing, batched actions, and gas sponsorship. Instead of using a traditional seed-phrase wallet, users log in with a passkey or a hardware device.
An Infinex account is essentially a smart contract wallet. Permissions are split between two layers:
- Operator key: used for day-to-day signing and actions.
- Super admin key: used for emergency recovery and withdrawal authorization.
That makes Infinex meaningfully different from a standard EOA wallet such as MetaMask or a hardware-wallet-backed address. The user experience can be smoother, but the security model is also more complex.
How Infinex connects to Hyperliquid
Hyperliquid is a perpetual futures exchange built around its native HyperEVM ecosystem. Official technical details are available in Hyperliquid Docs. Deposits and withdrawals are handled through HyperBridge: users bridge USDC from Ethereum or Arbitrum to Hyperliquid L1, then trade on Hyperliquid’s onchain order book.
Infinex wraps this flow into its own interface. In practice, a user can hold cross-chain USDC in an Infinex account, trigger a HyperBridge deposit, and then place Hyperliquid orders through Infinex using the account’s operator key.
For traders who want fewer manual steps, this can reduce friction. The trade-off is that you are no longer interacting with Hyperliquid only through a wallet you directly control in the traditional EOA sense; you are also relying on Infinex’s smart account architecture.
Fee structure
Infinex itself does not charge users an additional trading fee. Trading costs come from the Hyperliquid platform layer.
According to Hyperliquid’s own fee model, maker orders may receive rebates, while taker fees are roughly 0.025%–0.045% of notional value, depending on the relevant tier and HYPE staking conditions.
Traders should also account for HyperBridge costs. Bridging USDC into Hyperliquid involves gas fees and confirmation time. If you frequently make small deposits, bridge costs can reduce capital efficiency.
Security assumptions and risks
Infinex’s smart contract code has been audited, but users still need to understand how the permission model works. The super admin key is the user’s responsibility. If a passkey device is lost and no recovery setup is in place, withdrawals may become difficult or blocked.
This is different from the risks of a standard EOA wallet. Chainalysis research on wallet theft has shown that smart contract wallets and EOAs can have different attack surfaces. Smart accounts can improve usability, but they also introduce additional permission logic that users must understand before depositing significant funds.
Phishing remains a major risk. As OWASP’s phishing guidance notes, fake front ends and domain spoofing are common attack vectors against DeFi users. Always verify the domain and avoid signing transactions from untrusted links.
OneKey Perps: a more direct Hyperliquid workflow
For traders who want to use Hyperliquid while keeping direct control of their private keys, OneKey Perps is the more practical workflow.
OneKey supports major ecosystems including EVM chains and Solana, and it lets users access perpetuals trading without handing custody to a third-party operator layer. Your private keys remain under your control, and you can choose between the OneKey software wallet and OneKey hardware wallets depending on your security needs.
A straightforward setup looks like this:
- Download and set up the OneKey App.
- Secure your wallet with a proper backup.
- Use OneKey Perps to access perpetuals trading in a cleaner wallet-native flow.
- For larger positions, pair the app with a OneKey hardware wallet to reduce hot-wallet exposure.
This does not remove market risk or smart contract risk. Perpetuals are high-risk products, and leverage can wipe out your collateral. But for many Hyperliquid users, OneKey Perps offers a simpler security model: you keep direct key ownership while trading through a purpose-built wallet experience.
FAQ
Q1: Are assets in an Infinex account fully self-custodial?
Infinex accounts are onchain smart contract wallets, and the contract code is publicly verifiable. However, the control logic is more complex than a traditional EOA wallet because it uses operator and super admin permissions. Users should read the official documentation carefully before depositing large amounts.
Q2: What is better about using Infinex with Hyperliquid instead of connecting directly with MetaMask?
The main benefits are easier login through passkeys and more efficient batched operations. For traders who prefer direct private-key control, using a wallet such as OneKey and accessing perps through OneKey Perps can be just as smooth while keeping the key-management model more familiar.
Q3: Does Infinex charge extra trading fees?
As of the time of writing, the Infinex interface itself does not charge an additional trading fee. Costs come from Hyperliquid’s trading fees and HyperBridge gas costs.
Q4: How does Infinex compare with dYdX?
They are different products. dYdX is an independent perpetuals protocol with its own orderbook chain. Infinex is a front-end and smart-account layer, while trade execution is handled by Hyperliquid. The better choice depends on a trader’s preferences around liquidity, fees, chain ecosystem, and account model.
Q5: Which chains does Infinex support?
Infinex mainly supports EVM networks such as Ethereum, Optimism, and Base, with access to Hyperliquid L1 through HyperBridge. Exact network support can change, so users should check official announcements before moving funds.
Conclusion
Infinex + Hyperliquid gives traders a new way to access onchain perpetuals through a more unified account experience. Passkey login and batched operations can reduce friction, especially for users who manage assets across multiple chains.
The trade-off is the smart contract account model. Before using Infinex with meaningful capital, users need to understand operator keys, super admin recovery, bridge flows, and the risks of interacting through an additional account layer.
For most traders who want a practical way to trade perpetuals while retaining direct control of their keys, OneKey Perps is the more robust starting point. Download OneKey, set up your wallet carefully, and use OneKey Perps to access onchain perpetuals with a clearer self-custody workflow.
