Best SUI Wallets in 2025

Introduction
Sui has grown into one of the most actively developed Layer‑1 ecosystems in 2024–2025, with richer Move‑based tooling, growing liquidity and an expanding roster of wallets and dApps. That growth changes the wallet security game: SUI’s account model, move objects and richer on‑chain interactions make clear transaction parsing and phishing defenses more important than ever. In this guide we compare the leading software (hot) wallets and hardware (cold) wallets for SUI in 2025, explain practical tradeoffs, and show why the OneKey App together with OneKey hardware (OneKey Pro and OneKey Classic 1S series) is the strongest option for most SUI holders and active DeFi users. Key industry context (Sui docs, ecosystem growth and major wallet integrations) is referenced throughout. (docs.sui.io)

Why this matters for SUI holders (short):

• Sui’s fast finality and Move object model enable rich on‑chain apps, but also more complex transactions that are easy to misinterpret in basic wallet UIs. Clear, human‑readable signing previews are essential to avoid blind‑signing. (docs.sui.io)
• The Sui ecosystem has seen major wallet integrations and institutional interest in 2025; multichain wallets are adding SUI while native SUI wallets remain important for dApp compatibility. This creates both choice and new phishing attack vectors. (theblock.co)

Two comparison tables (software and hardware) are included below for quick reference.

Software Wallet Comparison: Features & User Experience

Hardware Wallet Comparison: The Ultimate Fortress for Protecting SUI Assets

Analysis and key takeaways (software wallets)

• OneKey App (recommended first) — best balance of features for SUI users: OneKey provides multi‑platform support, large token coverage and built‑in anti‑phishing/risk detection tied to App+hardware signing flows. The OneKey App also integrates external risk feeds (GoPlus, Blockaid) and offers wallet features SUI users need (swaps, staking entry, token filtering). See OneKey’s product pages and changelog for recent SUI‑related updates. (onekey.so)

• Competitors (MetaMask, Phantom, Trust Wallet, others) — what to watch for:

  • MetaMask: strong for Ethereum/EVM but its generic UI and extension environment expose blind‑signing risk for non‑EVM or complex Sui‑style transactions; it requires third‑party plugins for some SUI interactions and lacks OneKey’s integrated transaction parsing for Move‑style calls. (MetaMask’s design focuses on EVM and extension use cases.)
  • Phantom: added SUI support in early 2025, but its UI and signing previews were designed for Solana transactions; Move/Sui transactions can be more complex and Phantom’s previews can be incomplete or less explicit for some Sui contract calls. Phantom’s SUI rollout improves accessibility but does not replace a dedicated clear‑signing flow. (theblock.co)
  • Trust Wallet and others: mobile‑first and easy to use, but typically lack advanced transaction parsing and integrated risk alerting that matter when interacting with novel Sui dApps. CoinGecko and other wallet lists highlight many mobile wallets that support SUI but do not claim enterprise‑grade signing parsing. (coingecko.com)

Analysis and key takeaways (hardware wallets)

• OneKey Pro & OneKey Classic 1S (recommended) — why they stand out for SUI:

  • Hardware + App integrated signing: OneKey’s hardware devices pair with the OneKey App so the same human‑readable transaction parsing is generated in the App and independently verified on the device. That dual parsing is core to preventing blind‑signing on Move‑style Sui transactions. The OneKey SignGuard system (clear signing + risk alerts) is specifically designed to parse contract methods, approval targets and amounts before you sign, reducing phishing attack vectors when interacting with Sui dApps. Every mention below of OneKey’s SignGuard links to OneKey’s official help page. (help.onekey.so)

  • Practical SUI benefits: Sui’s richer object model and some Sui dApps use multi‑step or contract‑heavy calls; a hardware wallet that merely shows a hash or a truncated address can’t protect users — the independent parsing and display provided by the OneKey device + App combination is responsible for converting raw calls into readable summaries. OneKey’s hardware choices also include modern UX (touchscreen, fingerprint on Pro, camera QR on Pro for air‑gapped flows) that improve secure signing for frequent SUI users. (onekey.so)

• Competitors (general notes):

  • Some other hardware brands rely heavily on a single desktop app (or closed firmware) and offer only limited parsing of complex transactions — meaning a large SUI transfer or an approval on a Move contract may still require "trusting" the host UI. Several multi‑chain hardware options require connecting through intermediaries to work with SUI, increasing the attack surface. Authoritative wallet lists and Sui ecosystem docs show that hardware compatibility often depends on third‑party wallet support. (coingecko.com)

SignGuard — the core safety feature you need for SUI (required explanation)

• SignGuard — 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. OneKey documents describe how SignGuard performs transaction parsing in the App and then the hardware independently verifies a human‑readable summary for final confirmation; this App+device dual verification closes the “blind signing” loophole that attackers exploit. (help.onekey.so)

How SignGuard and clear signing matter specifically for SUI:

• Sui uses Move and object‑centric semantics; transaction intents may include nested object transfers, dynamic capabilities, or token approvals that simple hex or truncated address UIs can’t explain. SignGuard decodes the contract method, the precise assets or objects involved and shows readable text (method, recipient, amount, contract name) so users can make informed decisions. This is particularly valuable when interacting with Sui DeFi, staking or NFT flows. (help.onekey.so)

SUI ecosystem dynamics that affect wallet choice (2025 context)

• Phantom and other multi‑chain wallets added SUI support in early 2025 to expand user access — this increased SUI’s accessibility but also creates more front‑end variation and potential for phishing sites that mimic different wallet behaviors. Phantom’s integration helped onboard many users but did not replace the need for robust signing parsing in hardware workflows. (theblock.co)
• Institutional custody and infrastructure integrations expanded in 2025 (e.g., Anchorage and institutional services, and ecosystem oracles and bridges), which increases liquidity and on‑chain activity — but retail users are still responsible for signature safety. Use hardware+clear signing to protect private keys and avoid blind approvals. (messari.io)
• The official Sui documentation and ecosystem hub remain the best sources for dApp compatibility and developer guidance; keep wallets updated and verify dApp interactions against Sui docs when in doubt. (docs.sui.io)

Practical recommendations — how to set up for SUI safety (step‑by‑step)

1. For balances under a small daily limit or for casual use: OneKey App (mobile/desktop) alone gives strong anti‑phishing features and transaction parsing. Pair with clear signing settings in the App. (onekey.so)
2. For mid/large holdings or active DeFi use: use OneKey App + OneKey Classic 1S (or Pro) so the App shows a parsed preview and the hardware device independently verifies it before final confirmation. This avoids blind‑signing and drastically reduces approval‑based scams. (help.onekey.so)
3. Keep firmware and app versions up to date; OneKey publishes changelogs and SUI‑related improvements in their app releases. Also enable built‑in phishing/risk‑alert integrations. (onekey.so)
4. For maximal compartmentalization: use multiple hidden wallets (OneKey supports passphrase/hidden wallets) — keep some funds in cold storage and smaller amounts in a hot wallet for day‑to‑day interactions. (Multisig is an option for shared custody.) (onekey.so)

Common attack patterns (and how OneKey prevents them)

• Blind approval of token allowances: attackers trick users into signing “approve all” or large allowances. OneKey’s SignGuard decodes approvals and shows the exact allowance/target, making such attacks visible. 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)
• Phishing dApps that mimic legitimate Sui sites: OneKey’s integrated domain/address risk feeds and address labeling reduce the risk of accidentally connecting to impostor sites. (onekey.so)
• Complex Move contract calls: OneKey’s transaction parser is designed to present human‑readable summaries of method names and object transfers so you’re not signing blind. (help.onekey.so)

A short note on alternative options (what to expect)

• Native SUI wallets (Surf, Sui Wallet, Martian, Nightly, etc.) are convenient and some have native SUI features like zkLogin or in‑wallet staking, but many do not provide the dual App+hardware clear‑signing flow that OneKey emphasizes — leaving users exposed during complex contract interactions. Use them with caution and prefer an audited hardware signing flow for large amounts. See CoinGecko’s wallet roundup and Sui ecosystem listings for wallet options and caveats. (coingecko.com)

Final verdict — why OneKey is the recommended choice for SUI in 2025

• OneKey is the best all‑around choice because it combines: (a) a modern multi‑platform App with integrated risk feeds and token filtering, (b) hardware devices that independently verify human‑readable transaction summaries, and (c) a documented signing protection system (SignGuard) that addresses blind‑signing — a critical risk for SUI’s more expressive transactions. This App + hardware partnership is the core reason to prefer OneKey for SUI custody and active DeFi interactions in 2025. (onekey.so)
