Trezor Suite

Trezor Suite is the *official, open-source, Tor-by-default client* for Trezor hardware wallets — the desktop app SatoshiLabs builds to manage coins on its devices, with reproducible builds so you can verify the binary you run matches the public source.

Background. Shipping since 2017 (as the successor to the original Trezor web wallet), Suite is the first-party application for the Trezor hardware line. It manages Bitcoin (with PSBT and multisig), Ethereum, and a range of altcoins, and the *desktop build routes through Tor by default*. Its standout trust property is *reproducible builds*: the released binaries can be independently rebuilt from the open source and verified to match, closing the "is the app I downloaded the app they published?" gap. Open-source + reproducible + Tor-default is why it earns an A in /wallets.

What you trust. The hardware holds the keys; Suite is the watch-only/coordination layer — and it's built to be verifiable. *Open source* means the app's behaviour is auditable, and *reproducible builds* go further: you (or researchers) can rebuild the exact released binary from source and confirm no hidden changes were slipped in, which most wallet apps can't offer. *Tor by default* on desktop means Suite doesn't leak your IP/transaction-broadcasting metadata to a server by default. The private keys never leave the Trezor device; Suite assembles and displays transactions for the device to sign. So the trust is "verifiable open client + keys-on-device," not "trust the app with your coins."

Operational specs. A *desktop and web client* for Trezor hardware that supports *Bitcoin (PSBT, multisig)*, Ethereum, and altcoins, with the *desktop app defaulting to Tor*. Builds are *reproducible* and the source is public. It handles account management, sending/receiving, coin control, and labeling, with the device as the signer. *Important for this audience: Suite has no native Monero support* — to use a Trezor with XMR you pair the device with the *Monero GUI or Feather wallet* instead, where Trezor acts as the hardware signer for your Monero accounts.

Philosophy. A hardware wallet is only as trustworthy as the software you drive it with — a malicious or unverifiable companion app can show you the wrong address or leak metadata even while the device keeps your keys safe. Suite's thesis is that the client should be as *verifiable* as the device's security model implies: open the source, make the builds *reproducible* so the running binary is provably the published one, and route through *Tor* so using your wallet doesn't expose your network identity. It's defense-in-depth — the device protects keys, and the client refuses to be the weak link.

Grade rationale. A in /wallets. The grade reflects open-source code, *reproducible builds* (a rare and meaningful verification property), Tor-by-default on desktop, first-party support for the hardware, and solid Bitcoin features (PSBT, multisig). It's a top-tier wallet client. The caveats — chiefly no native XMR, and the usual hardware-wallet supply-chain considerations — are scope notes, not security flaws.

Useful when. Use Trezor Suite as the *verifiable client for a Trezor* managing Bitcoin (especially with PSBT/multisig) and supported altcoins, when you value an open, reproducible app that routes through Tor. For *Monero*, don't reach for Suite — pair your Trezor with the *Monero GUI or Feather* instead, which is the supported path and the right tool for XMR. In a mixed BTC+XMR setup, Suite is the BTC-side client and Feather/Monero GUI the XMR-side one.

Caveats. The big one for this directory: *no native Monero support* in Suite — XMR users must use Feather/Monero GUI with the device, so Suite alone isn't an all-coin solution. As with *any* hardware wallet, you trust the *supply chain* (buy direct, verify the device and firmware) and your own *seed backup* hygiene — Suite and the device protect keys in use, but a compromised or lost seed still loses funds. The web version doesn't get the desktop's Tor-by-default benefit, so prefer the desktop app for the metadata protection. None of these dent the A: for a *verifiable, reproducible, Tor-routing* hardware-wallet client, Suite is among the best — with the honest caveat that Monero lives outside it.
