Launched in October 2025, Trezor Safe 7 is the flagship of the Trezor lineup, which also includes Safe 5 and Safe 3. It is the first Trezor with Bluetooth, a battery and full iPhone support<\/strong>, and the first hardware wallet to use the TROPIC01 security chip, whose architecture is open to independent review.<\/p>\r\n\r\n\r\n\r\n

A hardware vulnerability was discovered in TROPIC01 in January 2026 and publicly disclosed in June. In this Trezor Safe 7 review, we explain what it means for wallet owners, how Bluetooth and post-quantum protection work, and which coins and networks the device supports. We then use our own test device to walk through desktop setup: connecting it, installing firmware, creating a wallet, recording the backup and setting a PIN. After that, we add networks, display a receiving address and set up a separate passphrase wallet.<\/p>\r\n\r\n\r\n\r\n

Who is Safe 7 for?<\/h2>\r\n\r\n\r\n\r\n

Safe 7 suits users who want to manage crypto from a computer or phone, including signing transactions from an iPhone over Bluetooth<\/strong>. Its battery lets you work without a cable, while the large touchscreen makes it easy to check addresses, amounts and DeFi transaction details. If you prefer a wired connection, you can use USB-C with a computer or compatible Android phone.<\/p>\r\n\r\n\r\n\r\n

If you are still choosing a model, our separate article \u201cWhich Trezor to choose: Safe 3, Safe 5 or Safe 7?\u201d<\/a> compares their screens, connectivity and security. Here, we focus on Safe 7 and how to set it up.<\/p>\r\n\r\n\r\n\r\n

Which coins and networks does Trezor Safe 7 support?<\/h2>\r\n\r\n\r\n\r\n

With its multi-coin firmware, Trezor Safe 7 supports thousands of coins and tokens. Trezor Suite lets you manage Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Cardano (ADA), XRP, Litecoin (LTC) and Dogecoin (DOGE), along with tokens on supported networks.<\/p>\r\n\r\n\r\n\r\n

TRON (TRX) and TRC-20 tokens, including USDT, are already supported in Trezor Suite<\/strong> on Safe 7. Since the June 2026 update<\/a>, TRON has been generally available in both the desktop and mobile versions of Suite. The app does not support the older TRC-10 token standard.<\/p>\r\n\r\n\r\n\r\n

When transferring USDT, make sure the sending and receiving networks match<\/strong>. For USDT TRC-20, for example, add a TRON account in Suite and select TRON as the withdrawal network on your exchange. TRC-20 transfers consume the network’s bandwidth and energy resources; if you do not have enough, fees are paid in TRX, so holding USDT alone may not be sufficient. See Trezor’s TRON and TRC-20 guide<\/a> for the full procedure.<\/p>\r\n\r\n\r\n\r\n

For other assets, check the official list of supported coins and tokens<\/a>, selecting Safe 7 and the network you need. The list also tells you whether an asset is available in Trezor Suite or requires a compatible third-party app. Support for a token on one network does not mean every network where that token exists is supported.<\/p>\r\n\r\n\r\n\r\n

Inside Safe 7: three chips from three manufacturers<\/h2>\r\n\r\n\r\n
\r\n
\"Three<\/figure>\r\n<\/div>\r\n\r\n\r\n

Safe 7 contains three chips: an STM32U5G microcontroller (ARM Cortex-M33, 160 MHz), a third-generation Infineon OPTIGA Trust M Secure Element with CC EAL6+ certification, and TROPIC01 from Czech company Tropic Square. Components from three manufacturers provide independent layers of protection, so compromising one chip should not be enough to access the wallet.<\/p>\r\n\r\n\r\n\r\n

In Safe 7, TROPIC01 enforces the PIN attempt limit in hardware through a mechanism called MAC-and-Destroy: each attempt permanently consumes a one-time slot<\/strong> in the chip, and only the correct PIN produces the required cryptographic result. The chip also stores factory certificates used to authenticate the device and generates random data for wallet creation.<\/p>\r\n\r\n\r\n\r\n

The seed, from which the wallet derives private keys, is stored in encrypted form in the microcontroller’s memory. Its decryption key is never stored in full: after you enter the correct PIN, it is derived from secret data held by several chips, exists briefly in memory, and is then erased. As a result, compromising a single component is not enough to read the seed<\/strong>.<\/p>\r\n\r\n\r\n\r\n

TROPIC01 has an open architecture that independent researchers can inspect. With many Secure Elements, access to technical details is restricted by nondisclosure agreements (NDAs). OPTIGA Trust M documentation is available without an NDA, although the chip itself does not have a fully open architecture. TROPIC01 was designed for open security audits, one of which uncovered the vulnerability discussed below.<\/p>\r\n\r\n\r\n\r\n

The TROPIC01 vulnerability: what was compromised and what it means for security<\/h2>\r\n\r\n\r\n
\r\n
\"TROPIC01<\/figure>\r\n<\/div>\r\n\r\n\r\n

Tropic Square commissioned an independent audit of TROPIC01 by Ledger Donjon, the security research team at Trezor’s competitor. In late January 2026, Donjon reported that laser fault injection had allowed it to extract some of the secret data protected by the chip. Building on those findings, Tropic Square engineers found a way to run their own firmware on the chip and obtain a secret used in PIN protection. Trezor published its response<\/a> on June 3, 2026.<\/p>\r\n\r\n\r\n\r\n

The attack requires physical access to the device<\/strong>, expensive laboratory equipment and specialist knowledge. An attacker must disassemble the wallet, desolder TROPIC01, open the chip package from the back, connect it to a custom board and precisely position the laser. This vulnerability cannot be exploited remotely or through malware on your computer.<\/strong> Trezor also states that it cannot be used to make a counterfeit Safe 7 with malicious firmware that survives a restart, ruling out that route for a supply-chain attack.<\/p>\r\n\r\n\r\n\r\n

According to Trezor, compromising TROPIC01 alone does not give an attacker access to the PIN, funds or wallet backup<\/strong>: the seed is not stored on that chip, and decrypting it requires two other independent layers of protection. A Safe 7 firmware update cannot fully fix the underlying hardware issue. Tropic Square plans to release a revised chip in late 2026, but Trezor has not confirmed whether or when it will use that revision in new Safe 7 devices.<\/p>\r\n\r\n\r\n\r\n

For everyday use, the main risks to watch for are phishing, exposure of your wallet backup and approving malicious transactions. If an attacker with a well-equipped laboratory is a realistic concern for you, factor in the vulnerability in one of the three protection layers: even after compromising TROPIC01, they would still have to defeat OPTIGA and the microcontroller<\/strong>. A strong passphrase provides additional protection when used alongside your backup and stored separately. It is not saved in the device’s persistent memory and is required to access the hidden wallet even if someone has the seed.<\/p>\r\n\r\n\r\n\r\n

Quantum-ready: what is protected?<\/h2>\r\n\r\n\r\n
\r\n
\"Post-quantum<\/figure>\r\n<\/div>\r\n\r\n\r\n

When Trezor describes Safe 7 as \u201cquantum-ready,\u201d it means post-quantum protection for the boot process, firmware and device authentication. Safe 7 verifies bootloader and firmware signatures using SLH-DSA-128, an algorithm standardized in 2024. Since May 2026, authentication in Trezor Suite has also used a digital signature generated by the microcontroller with the post-quantum algorithm ML-DSA-44. These measures protect against future attacks in which a quantum computer could help forge a conventional digital signature for an update or a device.<\/p>\r\n\r\n\r\n\r\n

The cryptography used for addresses and transaction signatures on Bitcoin, Ethereum and other networks remains unchanged, so these features do not make your coins quantum-resistant<\/strong>. A move to post-quantum cryptography depends on the blockchains themselves; whether Safe 7 could support it through an update will depend on future standards and the device’s resources. When choosing Safe 7 today, consider its screen, connectivity and ease of use: \u201cquantum-ready\u201d<\/a> describes protection for the device itself.<\/p>\r\n\r\n\r\n\r\n

Bluetooth and connection security<\/h2>\r\n\r\n\r\n
\r\n
\"Secure<\/figure>\r\n<\/div>\r\n\r\n\r\n

On Safe 7, Bluetooth and USB connections are secured by Trezor Host Protocol (THP)<\/strong>, an open-source protocol that encrypts commands and data and protects against interception, tampering and message injection. The Bluetooth pairing code and the one-time security code serve different purposes. You compare the first on both screens during Bluetooth pairing; Safe 7 displays the second for you to enter in Suite, including when connected by cable. In our walkthrough, the one-time code appeared before the firmware update, and we confirmed the connection again on the device after it restarted.<\/p>\r\n\r\n\r\n\r\n

If you do not need a wireless connection, you can disable Bluetooth in the settings and use USB-C. You will then be unable to sign transactions from an iPhone, because Safe 7 uses Bluetooth exclusively for this<\/strong>; its USB-C port only supplies power when connected to an iPhone.<\/p>\r\n\r\n\r\n\r\n

Whichever connection you use, always check the recipient address and amount on Safe 7\u2019s screen<\/strong>, as malware on a computer or phone can replace a copied address in the clipboard. The 2.5-inch display makes long addresses and transaction details easy to read. In September 2026, Trezor introduced Clear Signing<\/a> for supported contracts on EVM networks, which are compatible with the Ethereum Virtual Machine. When a contract is supported, the device displays a readable description of the action; for other contracts, Suite warns you about blind signing<\/strong>.<\/p>\r\n\r\n\r\n\r\n

Case, battery and water resistance<\/h2>\r\n\r\n\r\n
\r\n
\"Safe<\/figure>\r\n<\/div>\r\n\r\n\r\n

Safe 7\u2019s case is machined from a solid block of anodized aluminum, with Gorilla Glass 3 protecting the screen and a glass rear panel. It measures 75.4 \u00d7 44.5 \u00d7 8.3 mm<\/strong> and weighs 45 g<\/strong>.<\/p>\r\n\r\n\r\n\r\n

Safe 7 has an IP54 rating<\/strong>, providing limited dust protection and resistance to splashes from any direction. Do not submerge the device.<\/strong> If a review or older article cites IP67, use the IP54 rating in Trezor’s current documentation<\/a> as your reference.<\/p>\r\n\r\n\r\n\r\n

The LiFePO\u2084 (lithium iron phosphate) battery has a capacity of 330 mAh<\/strong>. According to Trezor, it can withstand up to four times as many charge cycles as conventional lithium batteries. It also tolerates a full discharge and retains its charge during long periods of storage. You can charge Safe 7 by cable or with a Qi2-compatible wireless charger. If the battery eventually fails, the wallet will still run on USB-C power and can continue to work with a computer or Android phone<\/strong>. Connecting to an iPhone requires Bluetooth.<\/p>\r\n\r\n\r\n\r\n

The operating temperature range is 0 to +45 \u00b0C<\/strong>. If you leave Safe 7 in a freezing car overnight, let it warm to room temperature before using it. Airport X-ray screening does not harm the device.<\/p>\r\n\r\n\r\n\r\n
