OneKey Wallet Features for Hyperliquid Traders [Complete List]

Jan 26, 2026

What changed recently (and why it matters to traders)

HyperEVM made “EVM-style” DeFi native to the trading L1

In February 2025, HyperEVM went live on mainnet, exposing an EVM JSON-RPC endpoint and a dedicated chain ID (999) so wallets and tooling can interact with smart contracts directly. (hyperliquid.gitbook.io)

HyperCore ↔ HyperEVM linking strengthened the “trade + build” loop

In March 2025, the ecosystem introduced mainnet linking between the high-performance trading core and the EVM environment, positioning the stack for faster token lifecycle and on-chain market access. (theblock.co)

Integration in practice: what you are actually doing

When you “integrate” OneKey into this flow, you typically do three things:

Hold the master account keys offline (hardware-backed) for high-value actions.
Sign Arbitrum USDC deposits and manage withdrawals with clear, on-device confirmations.
Optionally use Agent (API) Wallets for bots or third-party tools, while limiting their privileges.

OneKey Wallet features for traders (complete list)

1) Hardware-backed key isolation for critical actions

For traders, the biggest security upgrade is simple: private keys stay offline, and every sensitive operation requires a physical confirmation. This directly reduces the blast radius of browser malware, clipboard hijacking, and “silent signing” attacks during volatile markets.

2) Safer dApp access across desktop and mobile workflows

Traders don’t just “connect once”—they reconnect across devices, networks, and sessions. OneKey’s strength here is its cross-platform footprint (desktop app, mobile, extension-style workflows) so you can keep one consistent signing policy while switching environments.

If you want a public, non-OneKey-domain reference for OneKey’s open development approach, see the project’s GitHub organization page: OneKey on GitHub. (github.com)

3) Clean USDC deposit flow from Arbitrum (the common starting point)

Most traders start by bridging native USDC on Arbitrum into the trading L1. The bridge contract is public and verifiable, and deposits are credited quickly when done correctly. Key details worth treating as “checklist items”:

The Arbitrum bridge deposit credits the sender address (typical credit time: under a minute).
Minimum deposit is 5 USDC—sending less can result in loss. (hyperliquid.gitbook.io)

4) Withdrawal UX optimized for traders (signature-based + predictable fee)

Withdrawals are designed so the user signs on the L1 side, while Arbitrum execution is handled by validators—meaning you don’t need to hold Arbitrum ETH just to withdraw. The docs also specify a 1 USDC withdrawal gas fee on the protocol side. (hyperliquid.gitbook.io)

5) HyperEVM readiness: add the network and manage EVM assets

Once you start interacting with HyperEVM dApps (lending, vault tooling, on-chain strategies), the practical requirement is: your wallet must support a custom EVM network.

HyperEVM mainnet parameters (from official docs):

Network Name: Hyperliquid
Chain ID: 999
RPC URL: https://rpc.hyperliquid.xyz/evm
Currency Symbol: HYPE

6) “Master + Agent Wallet” separation for safer automation

If you run bots, DCA, or connect third-party tooling, you should treat automation keys as disposable signers, not as your vault keys.

The protocol supports Agent (API) Wallets that can be approved by the master account and used for signing/trading flows, with important operational nuances around nonce management and parallel processes. (hyperliquid.gitbook.io)

References:

Practical OneKey pattern

Keep the master account on OneKey (hardware-backed).
Create separate agent wallets per bot/process.
Periodically review/rotate agent wallets and permissions.

7) On-chain transparency: verify what you are signing (especially typed data)

Withdrawals and certain protocol actions rely on structured signing (typed data). The simplest “pro trader” habit is to treat signing as a verification step:

Confirm destination address and amount on-device.
Avoid signing when the UI cannot show meaningful details (especially after browser updates or new frontends).
Prefer repeating the action from an official interface if anything looks different.

8) Phishing resistance: trading UI clones are a real 2025–2026 risk

A major user concern lately is the rise of lookalike domains and fake “airdrop/claim” pages designed to trick traders into connecting and signing. Hardware confirmation helps, but the strongest defense is process:

Use bookmarked official entry points.
Verify the domain before connecting.
Cross-check contract addresses via a block explorer link when available.

Operational checklist (fast, trader-friendly)

Before depositing: confirm you’re sending native USDC on Arbitrum, and never below the minimum.

Before enabling automation: use a dedicated agent wallet per strategy/process.

Before using HyperEVM dApps: ensure Chain ID 999 + the official RPC are set correctly.

If you are (1) keeping meaningful collateral on-chain, (2) withdrawing regularly, or (3) running any automation via agent wallets, using OneKey as the master-key layer is a practical way to reduce signing risk while staying fully self-custodial.
