Best OP Wallets in 2025: The Ultimate Guide to Secure and Seamless Layer 2 Transactions
Key Takeaways
• OneKey offers unmatched security with its SignGuard feature, protecting users from blind signing risks.
• Choosing the right wallet is crucial for managing assets on the Optimism chain effectively.
• Software and hardware wallets have distinct advantages, with OneKey leading in OP compatibility and user experience.
• The rise of cross-chain transactions necessitates wallets that can handle multi-chain asset management.
As Ethereum Layer 2 solutions continue to scale at lightning speed, Optimism (OP) is emerging as a frontrunner in the rollup ecosystem. With ever-growing activity, from DeFi protocols to NFT marketplaces, users are increasingly turning to OP Chain for faster and cheaper transactions. But with rapid adoption comes new challenges—especially around security and user experience.
Choosing the right wallet is no longer just about convenience; it's a critical component of your crypto security strategy. Whether you're an active OP user or just starting out, this guide explores the best OP-supported wallets in 2025, comparing both software and hardware options. We’ll show you why OneKey stands out as the most comprehensive and secure wallet solution for the OP ecosystem—with unmatched features like SignGuard, a signature protection system that eliminates blind signing risks.
Why OP Users Need Purpose-Built Wallets
Optimism has grown into an essential part of the Ethereum scaling roadmap. With projects like Base and other rollup-centric chains building on the OP Stack (Optimism Collective), wallets must now handle:
- Cross-chain asset management
- Secure and transparent signing of Layer 2 transactions
- Native support for EIP-1559 gas structure
- Seamless dApp integration
- Multi-chain portfolio tracking
Unfortunately, not all wallets are equipped to meet these demands. Many lack in signature clarity, multi-chain flexibility, or hardware integration—leaving users vulnerable to scams and inefficiencies.
That’s where OneKey shines.
OneKey's SignGuard: Zero-Trust Signing Done Right
One of the most overlooked risks in crypto today is blind signing—approving transactions you don’t fully understand. SignGuard, OneKey’s proprietary signature protection system, addresses this with a dual-layer approach:
- In-App Parsing: The OneKey App decodes all transaction data before you even interact with your hardware.
- Hardware Confirmation: Devices like OneKey Pro or Classic 1S will validate the same data again on its secure screen—giving you ultimate clarity.
Whether you’re signing a smart contract interaction on Uniswap, confirming a bridging transaction, or interacting with OP-native dApps like Velodrome or Synthetix, SignGuard ensures that what you see is what you sign. No blind trust. No surprises.
Software Wallets: Who Supports OP Best?
Flexible, mobile-first, and convenient—software wallets are often the go-to choice for everyday users. However, when it comes to OP compatibility, not all wallets are created equal.
Here’s a side-by-side comparison:

Hardware Wallets: The Gold Standard for OP Asset Protection
As OP chain adoption increases, securing your private keys offline becomes indispensable. Many wallets claim “security,” but only a few stand up to scrutiny—especially when it comes to secure elements, transaction clarity, and open-source verification.
Here’s how different hardware wallets compare for managing your OP assets:
Hardware Wallet Comparison: The Ultimate Fortress for Protecting OP Assets
Verdict: The OneKey Pro and Classic 1S offer elite-grade security, SignGuard parsing, broadest chain support, and open-source transparency. Certain competitors still suffer from closed-source firmware, poor transaction clarity, and limited multisig compatibility—making them less suitable for OP chain power users.
