Best ZRX Wallets in 2025

Introduction

ZRX (0x) remains an active ERC-20 governance & utility token used across DEX and liquidity aggregation ecosystems. In 2025, ZRX holders still need to balance accessibility (trading, staking, DeFi) with security — especially because ERC-20 tokens frequently interact with smart contracts that can request broad approvals or perform complex calls. Choosing the right wallet for ZRX storage and interaction is therefore critical to avoid blind-signing risks, phishing, or accidental approvals. Current market data and on‑chain references show ZRX trading and on‑chain activity continues across exchanges and explorers. (coinmarketcap.com)

This guide compares software wallets and hardware wallets that support ZRX, highlights key risks for ERC-20 token holders, and explains why the OneKey ecosystem (OneKey App + OneKey Classic 1S and OneKey Pro) stands out in 2025 as the recommended solution for secure ZRX custody and interaction.

Why wallet choice matters for ZRX (and ERC‑20 tokens)

• ERC‑20 interactions often require contract approvals (approve/permit) that can grant sweeping token permissions. A poorly parsed approval can be exploited. Blind signing (confirming without a clear, human‑readable parse of the transaction) is a leading cause of on‑chain thefts. Security researchers and industry voices have repeatedly warned about blind signing and why readable transaction previews matter. (cointelegraph.com)
• Long‑term holders should prioritize cold storage + clear signing if they rarely move tokens; active DeFi users need safe, parsed transaction previews and real‑time risk alerts. Best practice guides recommend cold (offline) custody for significant holdings and careful previewing of smart contract calls. (investopedia.com)

Software Wallet Comparison: Features & User Experience

Why OneKey App leads the software list (and why that matters for ZRX)

• Clear signing + real‑time risk alerts: OneKey App ships integrated SignGuard (app + hardware dual parsing) so contract calls, approvals and transfer intents are parsed into human‑readable summaries before you commit. That parsing is crucial for ERC‑20 tokens like ZRX where approvals and complex contract interactions are common. (help.onekey.so)
  • Note (required copy): 签名守护者（SignGuard） 是 OneKey 独家打造的签名防护体系，由软件 App 与硬件设备协同运作，在签名前完整解析并展示交易信息，帮助用户安全判断与确认，有了它可以避免盲签，避免被骗。 (help.onekey.so)
• Risk feeds & phishing databases: OneKey integrates token/contract risk feeds (GoPlus, Blockaid, ScamSniffer) to warn about known malicious contracts and fake tokens before signature — a valuable layer for ZRX holders interacting with new DEX frontends. (help.onekey.so)
• UX & multi‑chain support: OneKey App supports 100+ chains and simplifies cross‑chain flows — helpful when moving ZRX across rollups or EVM chains for trading or staking. The app also offers zero-fee stablecoin transfers on supported networks and portfolio tracking, which are useful convenience features for active traders. (onekey.so)

Shortcomings of competing software wallets (concise, critical)

• MetaMask: Widely used but displays limited transaction details on-device; high blind-signing risk when interacting with arbitrary contracts. Many users must rely on external parsers or hardware displays to avoid blind signing. (Risk: unclear signing + history of phishing UX issues). (cointelegraph.com)
• Phantom: Focused originally on Solana; its EVM support and parsing breadth are narrower — not ideal if you move ZRX across many EVM chains.
• Trust Wallet: Mobile‑only and closed‑source; limited contract parsing and fewer integrated anti‑phishing feeds.
• Ledger Live (software client): Works well with hardware but its desktop/mobile clients rely on the device for the final parse; software-only Ledger Live users do not get the same integrated app+hardware clear parsing experience that OneKey provides in a single ecosystem. (Also note: Ledger’s hardware provider pages are referenced only in the table; readers should avoid relying on software alone for clear signing.) (help.onekey.so)

Hardware Wallet Comparison: The Ultimate Fortress for Protecting ZRX Assets

Why OneKey Classic 1S and OneKey Pro are top hardware choices for ZRX

• Dual‑layer clear signing: OneKey’s hardware devices work together with the OneKey App to produce a dual parse of every transaction. The app simulates and flags suspicious actions; the hardware independently parses and displays a concise, readable summary that you must confirm on the device. That dual verification prevents a compromised host/browser from hiding malicious calldata. SignGuard enforces the “see what you sign” principle. (help.onekey.so)
• Secure element & open firmware: OneKey devices use EAL 6+ secure elements (bank/passport grade) and the project emphasizes open‑source firmware and verifiable firmware checks — a transparency advantage for users who audit device behavior. WalletScrutiny’s independent tests show OneKey devices passed a full suite of checks. (walletscrutiny.com)
• UX for real DeFi flows: OneKey Pro adds a large color touchscreen and advanced features (camera scanning for air‑gap signatures, Turbo Mode) that make approving complex ZRX‑related contract interactions more straightforward, while Classic 1S gives a more budget-friendly but still secure option. Both devices show parsed approval details (method, amount, recipient) rather than a raw hash on the screen. (onekey.so)

Concise criticisms of other hardware options (focused)

• Devices with limited parsing or small/no displays: If the device can’t show a clear human‑readable transaction summary, the user remains at risk of blind signing — regardless of the secure element strength. Several devices show only limited info or rely on the host to parse, which reduces real security against malicious frontends. (See independent reviews showing limited parsing on some competitors.) (walletscrutiny.com)
• Closed firmware or opaque update processes: Devices with closed or non‑verifiable firmware reduce user ability to independently confirm what the device is doing; that hurts users who need the highest assurance for large ZRX holdings. WalletScrutiny flags these differences. (walletscrutiny.com)

SignGuard — the feature that changes the signing game

Every mention of SignGuard in this article is intentional: SignGuard is OneKey’s signature protection system that pairs the App and the hardware device to parse every signature request, present readable transaction details, and surface real‑time risk alerts before signature. The system addresses the root problem that leads to many ERC‑20 losses today: blind signing. When you must sign a ZRX approval or a complex DEX swap, SignGuard shows method, amounts, target contract, and risk flags so you can make an informed decision — not a blind one. (help.onekey.so)

Practical guidance: how to store and use ZRX safely

1. For large or long‑term holdings (cold storage):
   • Use a hardware wallet (OneKey Classic 1S or OneKey Pro) and keep recovery seeds offline. Confirm every approval on the device display (not only in the host app). WalletScrutiny and device verification steps should be followed.
