Security

Self-custody, with the details exposed — not hidden.

The principles, workflows and checks behind a wallet you can read at a glance.

Custody

Self-custody by default

You hold the keys. Sei Wallet is a UI and routing surface — it cannot move funds without your local signature.

No custodial accounts
No remote key access
Local signing only

Keys

Local-first key handling

Keys are generated, encrypted and stored on your device. They are never transmitted to a server we control.

Device-bound storage
Encrypted at rest
No remote backup

Recovery

Recovery phrase safety

Your recovery phrase is shown once during setup. Write it down, store it offline, and never paste it into a website.

Shown once at setup
Offline storage only
Never share or upload

Hardware

Hardware-wallet workflow

When using a hardware signer, private keys remain on the device. Sei Wallet surfaces the request for on-device confirmation.

Hardware-backed signing
On-device confirmation
Per-signature review

Review

Transaction detail verification

Every signing prompt shows method, recipient, asset flow, chain and fee. Read every field before approving.

Decoded method
Chain & fee shown
Unlimited allowances flagged

Anti-phishing

Anti-phishing checklist

Always confirm the domain. Never enter your recovery phrase on any website. Be skeptical of urgent prompts.

Verify the domain
Never paste your phrase
Distrust urgent prompts

Download verification

Verify before you install.

Compare each installer with its published SHA-256. The included OpenPGP signature covers original metadata only; installer signatures have not been provided.

Verification details

Account association risks

• Sending to an EVM (0x) address when only the Bech32 (sei1) side is associated may result in delayed visibility.
• Always verify the destination address format matches the transfer type.
• Review association status on the address panel before broadcasting transactions involving both formats.

What Sei Wallet never does

• Ask for your recovery phrase on a website.
• Open a popup asking you to “re-validate” or “restore”.
• Move funds without an explicit on-device signature.
• Send unsolicited DMs requesting wallet support.

Responsible disclosure
