What is a non-custodial wallet?

A non-custodial wallet stores the private keys on your device — not on a company's server. Nobody else can move, freeze or seize the funds. Lightning Pay is strictly non-custodial: the seed phrase never leaves your phone or laptop.

How do I back up my seed phrase?

Write the 12 words on paper (or stamp them into metal) and store the copy somewhere only you can reach — a safe, a deposit box, a trusted relative's house. Never photograph it, never type it into a cloud note, never email it to yourself.

Custodial vs non-custodial — what's the actual difference?

Custodial means a third party (Coinbase, Binance, Cash App) holds the keys; you hold an IOU. If they fail, freeze your account, or get hacked, you can lose access. Non-custodial means you hold the keys directly — the platform cannot freeze or lose what it never had.

What if I lose my phone?

Reinstall Lightning Pay on the new device and restore from the 12-word seed phrase. The wallet rebuilds from the keys on your paper backup — your balance is unaffected, because the coins live on Bitcoin's ledger, not on the phone.

Does Lightning Pay ever see my balance or seed phrase?

No. The seed phrase is generated and encrypted on your device only. We have no servers that hold user funds, no admin console that can move them, and no backdoor recovery. That's the trade-off of self-custody: full sovereignty, full responsibility for backups.

Security

Self-custody Bitcoin, without the headaches.

Lightning Pay never holds your funds. These guides explain why that matters, how to protect a 12-word seed phrase, and how to stay safe without becoming a hardware-wallet hobbyist.

Your keys. Your coins. No exceptions.

Every Bitcoin collapse of the last decade — Mt. Gox, QuadrigaCX, Celsius, BlockFi, FTX — has the same shape: users handed their keys to a custodian, the custodian failed, the coins were gone. Self-custody is the only structural fix.

Keys on your device

A non-custodial wallet stores private keys on your phone or laptop. The provider (us) literally cannot move, freeze or lose your funds — there is no server that holds them.

12 words is the master

The only authority over your wallet is the 12-word seed phrase your phone generates the first time you open the app. Treat it like a bearer bond.

No support reset

Self-custody means no support line can reset a forgotten password. Write the seed down, store it offline, never photograph it, never share it.

Self-custody, practical version

You do not need a vault on day one

Self-custody just means you hold the private keys that unlock your Bitcoin, rather than trusting a company to hold them for you. The mechanics are boring: a 12-word seed phrase, generated on your own device, is the master key from which every Bitcoin and Lightning address in your wallet is derived. Lightning Pay does the cryptography for you — your job is to write the 12 words down once and keep that paper somewhere only you can reach.

People over-complicate this. You do not need a $200 hardware wallet to hold $500 in Bitcoin. You need a piece of paper, a pen, and somewhere private to put the paper. As your balance grows, layer in a hardware wallet (Ledger, Trezor, Coldcard, BitBox — all pair with Lightning Pay), a steel backup, and eventually multi-sig.

Custodial vs non-custodial

The single most important question: who controls the keys?

A custodial wallet — Coinbase, Binance, Kraken, Cash App, Robinhood — holds the keys on your behalf. You hold an IOU against their database. They can freeze your account, get hacked, go bankrupt, or be ordered to seize the funds. All of these have happened to real users in the last few years.

A non-custodial Bitcoin wallet like Lightning Pay puts the keys on your device. We never see them, never store them, never have the option to move your funds. If our company disappeared tomorrow, your 12-word seed phrase would still recover the full balance in any compatible BIP-39 wallet — Sparrow, Electrum, Bitcoin Core, Blue Wallet, anything.

Seed-phrase storage — what works, what fails

What works

Write the 12 words on paper.
Store the paper somewhere physically secure (home safe, deposit box, trusted relative's safe).
For balances over a few thousand dollars, stamp into a stainless-steel seed plate.
Keep two copies in two physically separate locations.

What fails

Photographing the seed phrase (any cloud-backed photo roll is a leak waiting to happen).
Typing it into a password manager, notes app, Google Doc, or email.
Texting it to yourself "just in case."
Sharing it with "support" — Lightning Pay support will never ask, ever.

The passphrase upgrade (optional)

Lightning Pay supports an optional 13th word (BIP-39 passphrase) for plausible deniability — useful for large balances or high-threat environments. Most users won't need it; the 12-word backup alone is excellent security if stored correctly.

The structural property

Why FTX-style collapses can't touch self-custodied Bitcoin

Every major crypto collapse of the last decade had the same structural cause: users handed Bitcoin to a company, the company used it in ways users didn't know about (or got hacked), and when the music stopped the IOUs were worthless. The collapses had nothing to do with Bitcoin itself.

Self-custodied Bitcoin is structurally immune to this failure mode. There is no counterparty to fail. Lightning Pay could shut down tomorrow and your funds would be unaffected — the keys are on your device, the ledger is on the Bitcoin network, and any BIP-39 wallet can read them. Sleep better.
