This page shows how to set up Safe 3 step by step. I walk through unboxing checks, initializing a non-custodial hardware wallet, recording the seed phrase, optional passphrase use, firmware handling, and basic multisig ideas. In my testing over several months I noted a few small UI quirks and workflow tips you won't find in the quick-start card. (Helpful if you plan long-term cold storage.)

What you should have on hand before you start:
And yes—avoid public Wi‑Fi and shared computers while you initialize. If you bought the device secondhand, follow the advice in buying-safely.
Inspect the box, seals, and packaging before powering on. Genuine units generally show tamper-evident packaging and documentation. If anything looks altered or damaged, stop and consult supply-chain-authenticity. Why care? An attacker with physical access can try to tamper with firmware or supply small modifications that increase risk to your private keys.
Below are practical, non-model-specific steps that match the typical Safe 3 setup flow. Follow on-screen instructions from the official companion app as you go.
Why use the app? The app provides firmware checks, verifies the device, and guides you through secure initialization.
I noticed that a longer PIN gives more protection against someone trying to brute-force the device if it's stolen. But balance memorability and security.
If you plan to store the seed outdoors or in a safe deposit box, use a metal backup plate. See detailed steps in seed-backup-guide.
A passphrase lets you create an additional hidden wallet derived from the same seed. It can significantly increase privacy and security—if you use it safely.
Pros: creates separate accounts that aren’t visible without the passphrase. Cons: if you forget the passphrase you lose access; it’s not recoverable via the seed alone.
Read more on risks and best practices in passphrase-guide. What I’ve found: test any passphrase workflow with small amounts first.
See Safe 3 coins and wallet-integrations for details on supported chains and third-party wallets.
For a deeper procedure (how to verify, what to expect), see firmware-updates-guide. I recommend updating firmware promptly after setup to ensure the latest security fixes.
| Seed length | Pros | Cons |
|---|---|---|
| 12 words | Shorter to write and store; quicker confirmations | Slightly lower brute-force entropy (still strong for most users) |
| 24 words | Higher entropy; better long-term resistance to brute-force | Longer to record; more storage effort (often preferred for larger holdings) |
BIP-39 governs the word lists and checksum behavior. Choose what matches your threat model and backup capability.
Multisig requires compatible wallets and slightly more advanced operational procedures. See multisig-guide and air-gapped-guide for workflows. In my experience, multisig greatly reduces theft risk, but it adds operational complexity—so weigh the trade-off.
If you get stuck, try the official app’s recovery and troubleshooting steps first, then consult our troubleshooting and recovery-and-restore pages.
Q: Can I recover my crypto if the device breaks?
A: Yes. If you have the recovery phrase and it was recorded correctly, you can restore your private keys to another compatible hardware wallet or a supported recovery tool. Test recovery on a spare device or use a small test transaction.
Q: What happens if the company goes bankrupt?
A: Your wallet stores private keys; the device manufacturer going out of business does not erase the recovery phrase. As long as you control your seed phrase, you can restore your funds elsewhere. That’s the point of non-custodial, self-custody setups.
Q: Is Bluetooth safe for a hardware wallet?
A: Bluetooth can be convenient but adds an attack surface. If you plan to use Bluetooth, follow the device’s security guidance (keep firmware current, verify addresses on the device screen). For maximum isolation use a wired or air-gapped workflow.
Setting up Safe 3 carefully takes time, but it pays off in reduced long-term risk. After setup: verify addresses on-device, make multiple physical backups, decide on passphrase use (if any), and consider multisig for larger balances.

If you want a single immediate action: verify your recovery phrase and make a secure metal backup (or two). That protects you if the device is lost, damaged, or becomes unusable.
But remember—security is a process, not a one-time task. Safe storage is about habits.
