Backup for self-custody wallets

Lose the phone. Keep the keys.

LLC Portal backs up your wallet's recovery phrase as encrypted shares, split across your own devices and people you trust. No single loss a phone, a fire, a forgotten drawer can lock you out for good.

Why backups fail

A seed phrase on paper is one bad day from gone.

Most people back up a wallet exactly once, in exactly one place. That's fine until the one place fails.

  • Written down once, stored in one drawer, one safe, one house
  • Photographed "just in case," now sitting in a cloud photo backup
  • Known in full by exactly one person usually just you
  • Never checked again, so a faded or misread word is discovered too late

How the backup works

Your phrase, split into shares no single loss can undo.

LLC Portal never stores your full recovery phrase not encrypted, not anywhere. It's split at the moment of backup, and only ever reassembled on your own device.

Restoring a lost wallet

If today's the bad day, here's what happens.

Restoring doesn't mean digging through drawers. It means gathering enough shares from people and devices you already trust.

01 Request

Start a restore

Install LLC Portal on any device and start a restore request. It's tied to your wallet, not to the device you lost.

02 Gather

Shares check in

Your remaining devices and trusted contacts each confirm their share is genuinely yours to release not just a tap, a real check.

03 Reassemble

Wallet restored locally

Once 3 of 5 shares are in, your key is reconstructed on your device alone. LLC Portal never sees the reassembled phrase.

The security model

Designed to fail safely.

A backup system is only as good as its worst case behavior. LLC Portal is built so that no single bad moment can either lock you out or hand someone else your wallet.

  • No single share is enough

    One stolen phone or one compromised contact never gets close to a working key a threshold of shares is always required.

  • Revoke and reshare anytime

    If a device is lost or a trusted contact falls out of favor, revoke their share and issue a fresh one without touching the others.

  • Automatic share health checks

    LLC Portal periodically confirms each share is still reachable and intact, so a failure surfaces months before you'd need it not during a crisis.

  • Independent audits, published in full

    The splitting and reassembly code is open-source and independently audited, with reports published in full issues included.

Your backup, right now

All 5 shares checked in this month. You need any 3 to restore losing up to 2 still leaves your wallet fully recoverable.

Works with your existing wallet

LLC Portal backs up what you already use.

You don't need to move funds or switch wallets. LLC Portal backs up the recovery phrase itself, compatible with standard formats across networks.

Back up the wallet you already have.

Takes a few minutes to split your phrase into shares. No email, no custodial account, nothing for LLC Portal to lose on your behalf.
