Why doesn't Ledger have a dedicated Sei app?

Sei post-SIP-3 is EVM-compatible, meaning it uses the same cryptographic signing scheme as Ethereum. The Ledger Ethereum app handles all EVM-compatible chains (Sei, Polygon, Arbitrum, Avalanche, Optimism, etc.) — no need for chain-specific apps when the underlying signing logic is identical.

Does Ledger Nano S work, or do I need Nano X?

Both work. Nano S is older and lacks Bluetooth, but the cryptographic signing functionality is identical. Nano S+ is the current updated version. All three (Nano S+, Nano X, and Stax) support the Ethereum app and therefore work with Sei. Nano X's main advantage is Bluetooth + larger screen.

Can I use my Ledger seed phrase in software wallets too?

Technically yes — your 24-word recovery phrase derives keys any compatible wallet can import. But doing so defeats the security purpose of a hardware wallet. Treat the recovery phrase as backup-only; don't actively use it for daily wallet operations.

What happens if I lose my Ledger?

Your funds are safe as long as your 24-word recovery phrase is backed up. Buy a new Ledger, restore from the recovery phrase, and the new device controls the same accounts. Without the recovery phrase, lost Ledger = lost access.

Can I stake SEI from a Ledger account in Sei Wallet?

Yes. All Sei Wallet operations work — staking, unstaking, dApp interactions, contract calls. The Ledger signs each operation. Adds device-confirmation friction but provides the security benefit of keys on hardware.

Ledger Nano X with Sei · Setup Walkthrough

What you'll need

A Ledger Nano X (or Nano S+, or Stax — all work)
USB-C cable or USB-C → USB-A adapter
A computer running Sei Wallet (Windows, macOS, or Linux)
Ledger Live installed on the same computer
Your Ledger's 24-word recovery phrase backed up safely
About 10 minutes

If your Ledger is brand new, factory-set it up first using Ledger Live. Once initialized with a PIN and recovery phrase backed up, return here.

Why the Ethereum app handles Sei

Ledger has separate "apps" for different chains. Each contains the cryptographic logic for signing on that chain.

Post-SIP-3, Sei is an EVM-compatible chain. EVM-compatible chains all use the same signing logic (ECDSA secp256k1 on Keccak-256 hashed data) — the same logic the Ethereum app implements. So the Ethereum app correctly signs Sei transactions.

(For pre-SIP-3 sei1 addresses, the Ledger Cosmos app applies. Most users post-SIP-3 don't need this.)

Setup walkthrough

Step 1: Install Ledger Live and the Ethereum app

Download Ledger Live from ledger.com
Open Ledger Live, connect Nano X via USB
Unlock with your PIN
Navigate to Manager
Search "Ethereum", click Install, follow device prompts

Step 2: Connect Ledger to Sei Wallet

Open Sei Wallet
Choose "Connect Hardware Wallet" (Settings or Add Account)
Select Ledger
Connect via USB cable (or pair via Bluetooth — Nano X only)
Unlock the Nano X
Open the Ethereum app on the Nano X (left/right buttons, both to confirm)
Choose the account index (most users start with index 0)
Sei Wallet displays the Ledger-derived addresses — verify they match what your Ledger expects
Confirm the import

Step 3: Test with a small transaction

Before moving meaningful funds:

Send a small test transaction (e.g., 1 SEI)
Watch the Ledger screen — it displays recipient, amount, gas, chain ID (1329)
Approve on the device if everything matches. Reject if anything looks wrong.
Verify the transaction lands on seitrace.com

What to verify on the Ledger before signing

The Ledger's screen is the source of truth, not Sei Wallet. A compromised computer could show different details in Sei Wallet than what's actually being signed by the Ledger. The hardware wallet's screen is what you trust.

For each transaction, verify on the Ledger:

Recipient address. Read it character-by-character.
Amount.
Network / chain ID. Sei mainnet is 1329.
Gas / fee. Should be reasonable.
Function called (for contract interactions).

If anything doesn't match, reject on the Ledger. Investigate before retrying.

Common Ledger issues

"Sei Wallet doesn't see my Ledger." Most common: device not unlocked, Ethereum app not open, USB cable charge-only, or Linux missing udev rules (github.com/LedgerHQ/udev-rules).

"Asks me to enable blind signing." Some contract interactions require it. Enable only if you trust the dApp and initiated the transaction.

"Connection drops after every transaction." Try a direct USB connection without a hub.

"Bluetooth pairing isn't working on Nano X." Reset Bluetooth pairing in Ledger Live, re-pair. Fall back to USB if needed.

Adding more accounts

Derive multiple accounts from the same Ledger seed using different derivation paths. In Sei Wallet's "Connect Hardware Wallet" flow, choose "Add Another Account", select the next index. The Ledger derives the address using the standard EVM path (m/44'/60'/X'/0/0).

Each account is independently controlled by the Ledger but shares the same seed phrase backup.
