Hardware wallet warning: Both NGRAVE and Trezor are self-custody wallets — losing your seed phrase (or NGRAVE Perfect Keys / Graphene backup) means permanent loss of funds. Always purchase directly from the manufacturer (ngrave.io or trezor.io) to avoid tampered devices. Test recovery with small amounts before committing significant holdings. This guide covers wallet comparison and trade-offs, not investment advice.
How I Reviewed These Wallets: I have hands-on experience with both NGRAVE Zero (Belgian-engineered EAL7+ secure element, $398, fully air-gapped via QR codes) and the current Trezor lineup: Trezor Safe 3 ($79 entry), Trezor Safe 5 ($169 flagship with color touchscreen, launched 2024), and Trezor Safe 7 (newest flagship with 2.4″ color touchscreen + haptic engine, launched 2025-2026). This comparison reflects May 2026 reality — the original Trezor One and Trezor Model T are discontinued. The honest answer most users need: Trezor Safe 5 is the best overall hardware wallet of 2026 for most users; NGRAVE Zero is the premium choice for users with $50K+ portfolios who prioritize maximum security certification (EAL7+, the highest available).
NGRAVE versus Trezor in 2026 isn’t a head-to-head between equals — they’re targeting different users. NGRAVE Zero ($398) is the most security-certified consumer hardware wallet available, with EAL7+ formal verification (military/government grade), a 4-inch color touchscreen, fully air-gapped operation via QR codes, and a 1200 mAh battery for portable use. The company is backed by Belgium’s IMEC nanotechnology institute and COSIC cryptography research group. Trezor (made by SatoshiLabs, founded 2014, world’s first crypto hardware wallet brand) ships three current models — Safe 3 at $79 (entry-level), Safe 5 at $169 (flagship 2024), and Safe 7 (newest flagship with haptics) — all open-source, all using EAL6+ secure elements. Trezor’s open-source ethos and battle-tested ecosystem make it the default for most users; NGRAVE’s premium engineering makes it the choice for whales.

Quick Background: Who Makes These Wallets?
NGRAVE (Belgium, 2018)
NGRAVE is a Belgian digital asset security company founded in 2018, focused exclusively on hardware wallets and cold storage solutions. The company’s product suite includes the NGRAVE Zero (hardware wallet), NGRAVE LIQUID (companion mobile app), and NGRAVE Graphene (indestructible stainless steel backup plates). NGRAVE collaborates with two Belgian research institutions: IMEC (Interuniversity Microelectronics Centre — one of the world’s leading nanotechnology research centers) and COSIC (Computer Security and Industrial Cryptography research group at KU Leuven, one of Europe’s top cryptography labs). The Zero achieved EAL7+ certification — the highest Common Criteria certification level achievable, with formally verified design and implementation. This is military and government grade. As of May 2026, NGRAVE Zero is the only consumer hardware wallet with EAL7+.
Trezor (SatoshiLabs, Czech Republic, 2014)
Trezor is the original consumer hardware wallet brand, made by SatoshiLabs in Prague, Czech Republic. SatoshiLabs invented the consumer hardware wallet category in 2014 with the original Trezor One. The company has been a pioneer in open-source cryptocurrency hardware: all Trezor firmware is open-source on GitHub with reproducible builds, allowing third-party security researchers to verify what’s running on the device. As of May 2026, the current production lineup is the Trezor Safe 3 (entry-level $79), Trezor Safe 5 (flagship $169 launched 2024 with color touchscreen), and Trezor Safe 7 (newest flagship with 2.4″ color touchscreen + haptic engine). The original Trezor One and Trezor Model T are both discontinued — if you see content recommending those, it’s outdated.

Security: EAL7+ vs EAL6+
This is the single most important technical difference between NGRAVE and Trezor. Common Criteria (CC) certifications rate the security assurance level of a chip’s design and implementation:
- EAL5+ — Used by older Ledger devices (Nano S, Nano X). Solid commercial security.
- EAL6+ — Used by Trezor Safe 3/5/7, Cypherock X1, Tangem, Arculus, COLDCARD. Higher assurance than EAL5+, includes formal verification of the security architecture. Used in modern banking infrastructure.
- EAL7+ — Used ONLY by NGRAVE Zero (consumer market). Highest achievable certification. Includes fully formally verified design AND implementation. This is the standard used in military communications equipment and government cryptographic systems. The chip is mathematically proven to operate as specified.
What this means in practice: An EAL7+ chip provides the strongest available defense against advanced physical attacks (chip decapping, side-channel analysis, fault injection, glitch attacks, etc.). For most consumer use cases, EAL6+ is more than sufficient — there are no publicly known successful attacks against EAL6+ secure elements in commercial hardware wallets. EAL7+ matters when your threat model includes nation-state-level adversaries or you’re protecting holdings significant enough to attract sophisticated targeted attacks. For a typical retail user holding $5,000-$50,000 in crypto, EAL6+ (Trezor Safe 5) is the right choice — there’s no realistic attack scenario where EAL7+ would protect you better. For users holding $500,000+ or operating in adversarial jurisdictions, EAL7+ (NGRAVE Zero) starts to justify the premium.
Open-Source Transparency
Trezor publishes 100% of its firmware as open-source on GitHub with reproducible builds — the gold standard for hardware wallet transparency (matched only by Coldcard among competitors). Third-party researchers regularly review and enhance Trezor’s security; the open-source ethos has been a cornerstone of Trezor’s reputation since 2014. NGRAVE publishes its security architecture publicly and provides verifiable code, but the firmware is not as fully reproducible-build-verifiable as Trezor’s. NGRAVE’s security model leans more on formal verification and EAL7+ certification, while Trezor leans more on community auditability of source code. Both approaches have merit; for users who specifically want “I can compile and verify the exact code running on my device,” Trezor wins.
Air-Gap: NGRAVE Zero vs Trezor
NGRAVE Zero is genuinely fully air-gapped during all operations. The only USB connection is for charging the 1200 mAh battery. All transaction signing, address verification, firmware updates, and pairing happen via QR codes scanned by the device’s camera (and displayed on the 4″ touchscreen). The phone runs NGRAVE LIQUID app and shows QR codes; the device scans them, signs internally, then displays a signed QR code that LIQUID scans back. Zero physical contact between the device and any internet-connected hardware during normal operation. This is the strict definition of air-gap.
Trezor (all current models) uses USB-C connection to a computer or phone for transaction operations. While “Air-gap” software wallets like Sparrow can present transactions via QR codes for some workflows, the Trezor itself is designed for direct USB connection. This is faster and simpler than QR-based air-gap, but less secure against compromised hosts. For users running standard Trezor Suite workflows, this is acceptable; for maximum security paranoia, the QR-only NGRAVE Zero or the QR/microSD-capable COLDCARD are stronger air-gap options.
Backup Models: Graphene vs BIP-39 + Shamir
NGRAVE Zero uses standard 24-word BIP-39 seed phrases for recovery, but pairs with the proprietary NGRAVE Graphene stainless steel backup plate system. Graphene is a multi-piece steel backup designed to resist fire, water, corrosion, and physical damage indefinitely. The NGRAVE Perfect Keys feature provides additional optional cryptographic protections during seed generation.
Trezor Safe 5/7 support standard BIP-39 (12/18/24-word seed phrases) plus optional Shamir Secret Sharing backup (16-word shares, 2-of-3 or higher thresholds — similar concept to Cypherock X1’s SSS but optional rather than mandatory). For steel backups, Trezor users can use any BIP-39-compatible steel plate (Cryptosteel, BillFodl, Stamp Seed, etc.) — the backup ecosystem is broader and more competitive than NGRAVE’s proprietary Graphene system. Trezor Safe 3 supports BIP-39 only (no Shamir).
Companion App: NGRAVE LIQUID vs Trezor Suite
NGRAVE LIQUID is mobile-first (iOS + Android), no desktop app. The app communicates with the Zero via QR codes only. Functionality includes portfolio viewing, send/receive, address management, and transaction signing initiation. It’s polished but limited compared to Trezor’s broader ecosystem.
Trezor Suite is available on desktop (Windows, macOS, Linux) AND mobile (iOS + Android). Significantly more feature-rich than LIQUID: integrated coin trading, staking, lending integrations, address verification, multi-account management, watch-only views, support for third-party wallets (Sparrow, Wasabi, Electrum, MetaMask). Trezor’s broader software ecosystem is one of its key advantages over NGRAVE — power users have far more workflow options.

Frequently Asked Questions
Is NGRAVE Zero better than Trezor Safe 5?
“Better” depends on your needs. NGRAVE Zero ($398) has higher security certification (EAL7+ vs EAL6+), is genuinely fully air-gapped (QR-only operations vs Trezor’s USB), has a larger 4″ color touchscreen, and includes a battery for portability. Trezor Safe 5 ($169) has fully open-source firmware with reproducible builds, mature Trezor Suite ecosystem (desktop + mobile), broader third-party software support, and costs less than half. For users with $50,000+ portfolios who prioritize maximum security certification, NGRAVE wins. For most users (under $50K portfolio, want open-source verifiability + mature app ecosystem), Trezor Safe 5 wins. Both are legitimate choices with different priorities — neither is universally “better.”
What is EAL7+ certification and why does it matter?
EAL7+ is the highest Common Criteria security certification level, used in military communications equipment and government cryptographic systems. It requires formal mathematical verification of both the security design AND implementation — meaning the chip is provably correct against its security specification. EAL6+ (used by Trezor and most premium hardware wallets) requires formal verification of the design but not the full implementation. EAL5+ (used by older Ledger devices) requires structured testing but not formal verification. As of May 2026, NGRAVE Zero is the only consumer hardware wallet with EAL7+ certification. For typical retail users, EAL6+ is more than sufficient — there are no publicly known successful attacks against EAL6+ secure elements. EAL7+ matters when your threat model includes sophisticated targeted attacks (whales, journalists, high-profile figures, adversarial jurisdictions).
I see articles recommending Trezor One or Trezor Model T — should I buy those?
No — both are discontinued. SatoshiLabs retired the Trezor One and Trezor Model T in favor of the Trezor Safe series. Articles recommending those models are outdated. Current Trezor production lineup as of May 2026: Trezor Safe 3 ($79 entry), Trezor Safe 5 ($169 flagship 2024 with color touchscreen), Trezor Safe 7 (newest flagship with 2.4″ color touchscreen + haptic engine). All current models use EAL6+ secure elements (the original Trezor One and Model T did not have dedicated secure elements — a meaningful security upgrade). If you have an existing Trezor One or T that still works, it’s still a functional self-custody wallet, but for new purchases, the Safe series is the right choice.
NGRAVE vs Ledger — which is better?
Different priorities. NGRAVE Zero ($398): EAL7+ certification, fully air-gapped via QR, 4″ touchscreen, premium build, mobile-only app, smaller third-party ecosystem. Ledger (Nano S Plus $79, Stax $399, Flex $249): EAL5+ certification (lower than NGRAVE), USB connection (not strict air-gap), 5,500+ coin support (broader than NGRAVE), mature Ledger Live ecosystem (desktop + mobile), Bluetooth on premium models. Choose NGRAVE Zero if you want maximum security certification + air-gap. Choose Ledger Stax if you want premium UX with broad coin support + NFT lock screen at similar price. Choose Ledger Nano S Plus if you want budget + broad coins. See our Ledger Stax review.
Are Trezor wallets safe?
Yes — Trezor pioneered the consumer hardware wallet category in 2014 and has an excellent security track record. Current Trezor Safe 3, Safe 5, and Safe 7 models use EAL6+ Optiga Trust M secure elements (Infineon) for private key storage. All Trezor firmware is open-source on GitHub with reproducible builds — the gold standard for hardware wallet transparency. Third-party security researchers regularly review the code. There have been reported physical-attack vulnerabilities against the older Trezor Model T (using specialized lab equipment + many hours), which is partly why SatoshiLabs moved to dedicated EAL6+ secure elements in the Safe series. The realistic failure modes for current Trezor wallets are user-behavior issues: losing the seed phrase, sharing the PIN, or buying from an unauthorized reseller. For more on Bitcoin-specific privacy with Trezor, see our Wasabi Wallet review.
Are NGRAVE Zero wallets safe?
Yes — NGRAVE Zero is the most security-certified consumer hardware wallet available, with EAL7+ certification (the highest Common Criteria level), formal mathematical verification of the chip’s design and implementation, fully air-gapped operation via QR codes (no USB connection during transactions), and backing from Belgium’s IMEC nanotechnology institute and COSIC cryptography research group. There are no publicly known successful attacks against NGRAVE Zero since its 2020 launch. The realistic failure modes are user-behavior issues: losing the 24-word seed phrase + the NGRAVE Graphene steel backup, sharing the PIN, or buying from an unauthorized reseller.
Can I use NGRAVE Zero or Trezor for DeFi and NFTs?
Both support DeFi and NFTs. Trezor integrates broadly with MetaMask, Rabby, WalletConnect, and most DeFi/NFT platforms via its open-source SDK. NFT support is well-developed. NGRAVE Zero supports DeFi via WalletConnect and select integrations through NGRAVE LIQUID, but the third-party DeFi/NFT ecosystem is smaller than Trezor’s. For heavy DeFi/NFT users, Trezor’s mature integrations are the more convenient choice. For users primarily holding long-term cold storage with occasional DeFi access, either works. For broader smart contract wallet context, see our best smart contract wallets guide.
Trezor Safe 5 vs Safe 7 — which should I buy in 2026?
Both are flagship Trezor models. Safe 5 ($169, launched 2024): color touchscreen, EAL6+ Optiga Trust M, optional Shamir Secret Sharing, mature firmware. Safe 7 (newest, late 2025/early 2026): larger 2.4″ color touchscreen, haptic engine for tactile feedback, EAL6+ secure element, all features of Safe 5 plus newer hardware. Pricing: Safe 7 sits at the top of Trezor’s range. Choose Safe 5 if you want the proven 2024 flagship at lower price — most user reviews still rank Safe 5 as “best overall 2026.” Choose Safe 7 if you want the newest hardware with haptic feedback and larger screen, and the modest price premium doesn’t matter. Both share the same security architecture and Trezor Suite ecosystem.
Final Verdict: NGRAVE vs Trezor 2026
For most users in 2026, the answer is Trezor Safe 5 ($169). The blend of open-source firmware with reproducible builds, EAL6+ secure element, color touchscreen, mature Trezor Suite ecosystem (desktop + mobile), and broad third-party software support (Sparrow, Wasabi, MetaMask, Sparrow + COLDCARD pairing for multisig) makes it the best overall hardware wallet of 2026. The 2014-onward track record of SatoshiLabs adds confidence. For budget-focused users, the Trezor Safe 3 at $79 delivers the same EAL6+ security with a less premium UX.
For users with $50,000+ portfolios who specifically want maximum security certification (EAL7+ vs EAL6+) or genuinely fully air-gapped operation (QR-only vs Trezor’s USB), NGRAVE Zero ($398) is the right premium choice. The 4″ color touchscreen, 1200 mAh battery, and military-grade EAL7+ certification justify the price for whales who prioritize maximum security over ecosystem maturity.
Both products are legitimate, both have excellent security track records, and either will protect your crypto far better than leaving it on an exchange or in a software wallet. The decision comes down to portfolio size and priorities — not “which is better.” Most users should buy Trezor Safe 5; serious whales should consider NGRAVE Zero. For Bitcoin-only users, also consider COLDCARD (the Bitcoin maximalist’s choice with dual secure elements + 100% open-source) or Bitkey (consumer multisig from Block Inc).
