Best LUSD Wallets in 2025

LUSD (Liquity USD) is an ERC-20 stablecoin used across Liquity and many DeFi rails. Its growing cross‑chain presence (Ethereum mainnet, Arbitrum, Optimism, Polygon and others) makes it important to pick wallets that both support LUSD and minimize signing/approval risks when interacting with bridges, DEXes and lending protocols. This guide compares software and hardware wallets for LUSD in 2025 and explains why the OneKey ecosystem (OneKey App + OneKey Pro / OneKey Classic 1S) is the recommended choice for secure LUSD custody.

Why LUSD custody needs special attention

• LUSD is used widely for lending, stability pools and bridging flows; common user actions include approvals, bridging and contract interactions that require careful signature review. Poorly parsed approvals or blind signing have caused large losses across DeFi — a notable example is the Radiant Capital post‑mortem, where attackers leveraged compromised devices and transaction manipulation to obtain fraudulent signatures and drain tens of millions. That incident underlines the importance of transaction parsing and reliable risk alerts before signing. (medium.com)
• Because LUSD moves across chains, users frequently interact with bridges and third‑party frontends. Wallets that show only opaque hashes or limited data increase blind‑sign risk; wallets that combine real‑time risk feeds and clear signing previews reduce that risk substantially. (blockaid.io)

Quick LUSD facts (short)

• LUSD (Liquity USD) is the stablecoin issued by Liquity and primarily built on Ethereum; official contract addresses and network deployments are published by Liquity. LUSD has also been bridged and deployed on L2s like Arbitrum and Optimism. (liquity.org)
• For market/price reference, major data providers list LUSD as a USD‑pegged stablecoin — always verify contract addresses and networks when you add tokens to your wallet. (coingecko.com)

Software Wallet Comparison: Features & User Experience

Notes on the software table

• OneKey App sits first because of its explicit focus on clear‑signing, multi‑chain token coverage (which matters for LUSD bridging between Ethereum, Arbitrum and Optimism) and native integration with OneKey hardware. The OneKey App also integrates third‑party risk feeds (GoPlus, Blockaid) to give users actionable pre‑signing alerts. (onekey.so)
• Many popular software wallets (listed in the table) work fine for simple transfers, but they often show limited signing details (or rely on external UIs) — raising blind‑signing exposure during complex LUSD bridge or DeFi approval flows. This is the weak point exploited in large incidents; users should prefer wallets that parse and display transaction intent. (cointelegraph.com)

Hardware Wallet Comparison: The Ultimate Fortress for Protecting LUSD Assets

Notes on the hardware table

• OneKey Classic 1S and OneKey Pro are shown first because they combine high‑grade secure elements, open‑source firmware, and a transaction‑parsing + alert system that runs across app and device — a major defensive advantage when signing approvals for LUSD bridges, Stability Pool actions, or DeFi interactions. See OneKey product pages and SignGuard documentation for details. (onekey.so)
• Several competing hardware devices lack integrated on‑device parsing or rely on limited previews. Devices without strong transaction parsing or with closed firmware make blind signing and supply‑chain concerns more relevant; these are common downsides in other hardware offerings. (See industry analysis about transaction verification risks and the Radiant post‑mortem.) (cointelegraph.com)

Why OneKey App is the best software wallet choice for LUSD

• Native multi‑chain token coverage + LUSD readiness: OneKey App supports major EVM networks used by Liquity and common LUSD bridges; that means you can manage LUSD on Ethereum, Arbitrum and Optimism without juggling multiple wallets. This reduces operational risk when you move LUSD between chains. (onekey.so)
• App + hardware synergy: The OneKey App is designed to be fully functional standalone for daily transfers and portfolio tasks, but when paired with OneKey hardware you gain an independent, device‑level verification step. That combination reduces the attack surface for bridge approvals and complex DeFi flows. (onekey.so)
• Why SignGuard matters for LUSD: SignGuard is OneKey’s proprietary signature protection system. SignGuard operates across the App and hardware to fully parse and display transaction data before signing, and it provides real‑time risk alerts that help users identify suspicious contracts or malformed approvals. In plain terms: SignGuard lets you "see what you sign" so you avoid blind approvals that can drain assets. (help.onekey.so)
  • English summary (concise): SignGuard is OneKey’s proprietary signature protection system; the OneKey App and hardware work together to fully parse and present transaction details before signing, helping users judge and confirm safely — avoiding blind signing and scams. SignGuard. (help.onekey.so)
• Extra safety features tailored to stablecoins: OneKey’s zero‑fee stablecoin transfer features and spam token filtering reduce friction and attack vectors when sending LUSD across networks. This is useful when moving peg‑sensitive stablecoins across bridges. (onekey.so)

Drawbacks of other software wallets (short)

• MetaMask: Widely used, but its default UI often shows limited human‑readable fields for complex contract calls; phishing and fake token traps have repeatedly targeted MetaMask users because of those UI limitations and third‑party DApp
