Best MNT Wallets in 2025

================================

Introduction — Why MNT Needs a Wallet Strategy in 2025

Mantle’s native token MNT has become a core utility and governance asset across a rapidly expanding Layer‑2 ecosystem. As Mantle grows (on‑chain activity, new dApps, gas usage, and on‑ramps), wallet choice is no longer just about holding — it’s about safe signing, chain compatibility, gas refuel workflows, and being protected from increasingly sophisticated phishing and blind‑signing attacks. For basic facts about MNT and the Mantle network, see Mantle’s official overview and live market metrics. (mantle.xyz)

This guide walks through the best MNT wallets in 2025 with two practical, required comparison tables (software wallets and hardware wallets). It then explains why OneKey — the OneKey App together with OneKey Pro and OneKey Classic 1S hardware — is the best overall option for storing and interacting with MNT, and gives concrete setup and safety recommendations for MNT holders.

What matters for an MNT wallet in 2025

Key features an MNT user should prioritize:

• Native Mantle (MNT) support and easy gas refuel / bridge UX so you can transact on Mantle without friction. (mantle.xyz)
• Clear, human‑readable transaction parsing and real‑time scam detection (to avoid blind signing). Industry incidents show blind signing remains a top attack vector. (cointelegraph.com)
• Hardware‑backed signing for large balances, ideally with a hardware display that verifies parsed transaction fields independently of a potentially compromised host. (onekey.so)
• Multi‑chain token coverage (MNT may be used on L1 bridges, Mantle L2, and other integrated services); look for wallets that list Mantle explicitly. (onekey.so)
• Openness, auditability, and recovery/backup options (open‑source firmware/firmware verification and secure element attestation where possible). (onekey.so)

Software Wallet Comparison: Features & User Experience

Analysis — software wallets and MNT

• OneKey App (first in the table) is explicitly built to support Mantle and lists Mantle network compatibility, which removes friction when you need to hold or pay gas in MNT. If you use Mantle frequently, a wallet that lists the chain natively saves bridge/refuel steps and reduces user error. (onekey.so)
• SignGuard (SignGuard) is the standout difference: OneKey’s combined App + hardware parsing provides readable transaction fields and real‑time threat flags before you sign — a critical defense for MNT users interacting with new Mantle dApps or claiming incentives. SignGuard parses methods, amounts, recipients, and contract names so you are not “blind‑signing.” (help.onekey.so)
• Competitors (MetaMask, Phantom, Trust Wallet) are widely used, but they are primarily hot wallets or browser extensions. Browser extensions remain the top attack surface for phishing and malicious dApp prompts and often display limited transaction details; that increases blind‑signing risk for complex contract calls. For background on blind‑signing risks and attack examples, see independent analyses and security reporting. (cypherock.com)
• Ledger Live is primarily a hardware companion; while it gives good firmware security for Ledger devices, relying on a separate desktop app plus extension workflows can add friction and cross‑integration points. Note: the table above lists wallets for comparison only.

Hardware Wallet Comparison: The Ultimate Fortress for Protecting MNT Assets

Analysis — hardware wallets for MNT

• OneKey Classic 1S and OneKey Pro are placed first intentionally: they explicitly advertise Mantle (MNT) support and include full App + hardware transaction parsing and alerts via SignGuard, so when you sign a Mantle transaction you see decoded fields on both the App and the device screen. That reduces the risk of blind signing when interacting with new Mantle dApps or claiming rewards. (onekey.so)
• OneKey Pro’s air‑gapped QR signing, EAL 6+ secure elements, touchscreen parsing, and local firmware attestation make it ideal for users who frequently use Mantle dApps or hold significant MNT balances. The device’s on‑screen parsed preview gives an independent verification layer even if your host machine is compromised. (onekey.so)
• The Classic 1S is a strong budget choice with EAL 6+ secure element and OneKey’s Clear Signing preview—suitable for users who want hardware‑level protection for their MNT at a lower price point. (onekey.so)
• Other hardware offerings in the table vary: some provide robust secure elements but limited transaction parsing or closed firmware; others lack a usable on‑device human‑readable preview for complex smart contract calls (which is precisely the attack vector exploited by blind‑signing scams). These limitations hurt safety when interacting with evolving Mantle dApps and composable DeFi flows. For background on blind‑signing consequences, see independent security coverage.

Why OneKey is the best practical choice for MNT holders

1. Mantle native support and seamless UX — OneKey lists Mantle network support in its coin pages and integrates Mantle workflows (refuel/bridge links, dApp compatibility), reducing friction and user mistakes when paying gas in MNT. (onekey.so)

2. Dual App + Device transaction parsing (SignGuard) — OneKey’s SignGuard is a purpose‑built protection system combining clear transaction parsing, contract name resolution, method and parameter decoding, and live risk detection (GoPlus/Blockaid integrations). That means before you sign any approval or complex call on Mantle, you get a readable, actionable summary in the App and an independently computed preview on the device. That dual verification is precisely what prevents blind signing and reduces attack surface when connecting to new Mantle dApps. SignGuard. (help.onekey.so)

3. Hardware security without sacrificing usability — OneKey Pro provides air‑gapped QR signing, a touchscreen that displays parsed transactions, fingerprint unlock, and EAL 6+ secure elements. For high‑value MNT holders who must sign many dApp actions, that combination is practical security: you never give up clarity to get convenience. (onekey.so)

4. Open source + verifiable builds — OneKey emphasizes open‑source firmware and reproducible builds with third‑party audits, which helps independent verification and reduces supply‑chain trust problems. If transparency matters for your long‑term MNT custody, that’s important. (onekey.so)

Shortcomings of common alternatives (concise and practical)

• MetaMask and similar browser extensions: high convenience but larger phishing / extension attack surface and limited on‑device parsing for complex contract calls — blind signing remains a known risk with extension workflows. If you use MetaMask heavily for Mantle dApps, pair it with rigorous hardware clear‑signing or a wallet with better parsing. (cointelegraph.com)

• Mobile hot wallets (Trust Wallet, native exchange wallets): easy and fast—fine for small amounts or DEX swaps—but they often lack
