The multisig vault
Litecoin has been missing.
Casa and BitKey brought serious multisig to Bitcoin holders. LiteSig does the same for Litecoin: browser-based, non-custodial, no software to install. And you do not need anyone else: hold all three keys yourself, in three different places.
No card, no signup. Try the full multisig sandbox on testnet before creating an account.
Why I built this
I've been a Litecoiner for a long time, long enough to have helped integrate Simplex and Moonpay into the Litecoin Foundation's Litewallet app. I've always admired what Casa and BitKey built for Bitcoin holders: proper multisig that a normal person can actually set up without a computer science degree.
Every time I looked for the same thing on Litecoin, I found wallet files, command-line tools, and instructions that assumed you already knew how this all worked. So I built LiteSig.
The other thing that pushed me: most Litecoin holders I know have no plan for what happens to their coins when they're gone. That's not a morbid thought. It's a practical one. Inheritance wasn't an afterthought in LiteSig; it was one of the first things I built.
gneo54How it works
-
1.Create your vault
Pick your quorum: 2-of-3, 3-of-5, whatever fits your situation. Each cosigner generates their own key on their own device. No key ever touches our servers.
-
2.Cosigners join from a link
No emailing wallet files back and forth. Each cosigner opens LiteSig in their browser, generates their key, and the vault assembles itself.
-
3.LiteSig coordinates every spend
Anyone can propose a transaction. It only broadcasts once enough cosigners sign. LiteSig routes the signing requests, tracks who's signed, and notifies who hasn't. Nobody has to email PSBT files around. That coordination is what your subscription pays for.

Who it's for
Never lose a coin to a single mistake
One key on your phone, one on a hardware wallet, one secure backup. A 2-of-3 vault survives any single loss. A thief would need to compromise two separate devices at the same time.
Plan your inheritance without giving up control
Add a trusted heir as a cosigner. They can co-sign after you're gone, but can't move a litoshi while you're alive. No solicitors, no probate delays. Just your family keeping what's theirs.
Require approval before any funds move
A 3-of-5 quorum means every spend needs sign-off from multiple people. No single employee can drain the treasury, even if their laptop is stolen or their credentials are compromised.
Security
All cryptography runs in your browser. Private keys are generated using the browser's built-in
SubtleCrypto API, encrypted with a passphrase only you know, and never transmitted
to our servers. Even a full breach of LiteSig's infrastructure would leave an attacker with
only encrypted blobs, useless without your passphrase.
The code that generates and signs your keys is open source and independently auditable. Your vault uses standard formats (BIP39, BIP48, PSBT), recoverable in any compatible wallet if LiteSig ever disappears.

Common questions
Do you hold my Litecoin?
No, and I couldn't even if I wanted to. Your private key is generated in your browser, encrypted with a passphrase only you know, and never sent to our servers. If LiteSig were completely breached tomorrow, an attacker would get encrypted blobs, useless without your passphrase.
What happens if LiteSig shuts down?
Your funds stay yours. Vaults use standard BIP39/BIP48/PSBT formats, the same ones Bitcoin hardware wallets use. You can recover and spend from any compatible wallet using your seed phrase. I built it this way deliberately: you shouldn't be locked into any service, including mine.
What is multisig, in plain English?
Instead of one key that unlocks everything, you have N keys and need M of them to spend. Lose one key and you're fine. A thief gets one key and they're stuck. It's how serious Bitcoin holders have secured large amounts for years. LiteSig brings that same model to Litecoin.
Do I need other people to use multisig?
No. Most vault owners hold all three keys themselves: one on this device, one on a second device or hardware wallet, one on paper in a safe place. LiteSig's solo vault mode sets this up for you in one flow. Any two keys can move funds, so losing one costs you nothing, and a thief who finds one gets nothing. Shared vaults with real cosigners are there when you want them, for a business or an inheritance plan.
What happens if I cancel my subscription?
Your coins are never at risk. LiteSig is non-custodial. After canceling you can still view and export your vaults, and spend from them in any compatible wallet. What the subscription covers is the ongoing coordination service: routing signing requests and enabling new mainnet vaults. Cancel and you keep the vault; you lose the managed coordination until you resubscribe.
How is this different from just using Electrum-LTC?
Electrum is a great tool if you're comfortable with the command line and want to manage PSBT files manually. LiteSig handles the coordination between cosigners, the part that's genuinely hard to do yourself. Your cosigners don't need to know what a PSBT is, nobody emails wallet files around, and the signing flow works from any browser.
