Disaster-Proof Your Assets

We built a better backup system - for real people, not computer nerds. A turn-key system ensures nothing is left to chance. With the knowledge you've made your wallets robust and secure, comes the peace of mind to hold them long term.

Imagine a bulletproof backup of your crypto wallet seed phrases completely offline, encrypted, and accessible only to you. No risk of hacks, no lost access... no forgotten passwords. It's offline crypto hardened cold storage.

The serious self-custody solution built for regular folks who hold crypto / digital assets such as Bitcoin, Ethereum, Solana, Litecoin, XRP, Dogecoin, and maybe even a whole raft of memecoins that might moon. They all deserve a solid backup.

Hiding your seed phrase is not a security plan

If you've ever had that quiet thought — "what if I lose access?" — you're not alone. Most people either avoid thinking about it… or they try to improvise with what’s lying around.

Peace of Mind, Built In

Peace of mind doesn't come from the storage device — it comes from knowing you’ve planned for failure, recovery, and even the unexpected.

Because real security isn’t just about where you store your keys — it’s about how you prepare for what life might throw at you. Fires, floods, mistakes, lost passwords, even the unthinkable. Peace of mind means you’ve thought it through… and set things up so your future self — or your family — won’t be scrambling in a crisis.

It’s not paranoia — it’s just not leaving things to chance. When your backup’s solid, you can stop worrying and get on with life.

Backup Security Needs An Overhaul

Houston, we have a problem: wallet backup and recovery. But its not the tech, its the human layer. Asking people to manage a 24-word seed phrase for access to their money is a big ask. Most aren’t security pros, so backups stay fragile... prone to loss, theft, hacks, and simple human error.

A single paper or steel backup =
single point of failure

But making additional unprotected copies exposes you to more risk. We fix this with a simple idea: your seed is split into two files — a Seed Map and Seed Codes — linked by a unique cipher, and encrypted. Alone, each file is useless. Together, they restore your wallet.

This makes backups:

Safer to duplicate
copy them freely without risking compromise
Easier to distribute
store across real-world locations with no weak link
Ready for inheritance
pair with a deadman switch so your family can recover assets when it matters most

It’s not about complexity. It’s about resilience. EncryptFire turns fragile backups into vaults you can pass on with confidence.

▶️ The App

We're all about self-security. No 3rd party custody here.

ENCRYPTFIRE is an app that runs offline in your web browser. It's designed to work with all major wallets. You can make multiple secure cold storage backups of any wallet that's BIP39 compliant (12, 18, 24 or even 25 seed words). That's 99.9% of the wallets out there. For more info see our FAQs.

Built built it, We use it

There was no 'point-n-click' dead simple way for non-technical people to safely protect a crypto wallet, and “pass it on after you're gone”. So we built it.

EncryptFire is a standalone tool you run directly in your browser. It’s just HTML + JavaScript with no servers involved, so nothing ever leaves your computer. You can even use it fully offline on an air-gapped machine (... in fact we encourage it. Read more here).

How it works:

A cipher map — a scrambled codebook of every possible seed word (the entire BIP-39 wordlist of 2,048 words).
A short list of numbers that point to your actual seed words inside that map.

On their own, neither file reveals anything. To recover the seed, you need both halves together plus the master password. The cipher map itself is encrypted with AES and protected by a mandatory 34-character password (letters, numbers, symbols), making brute-force guessing impractical.

Why it’s safer:

Physical separation: keep the two halves on different USB drives, stored in different places. If one is lost or stolen, it’s useless without the other.
Redundancy without full exposure: you can make multiple backups of each half for safety. Unlike duplicating a plain seed phrase, these copies are harmless on their own and only become meaningful when combined.

Ease of use:

A step-by-step wizard guides you with simple button clicks instead of typing seed words. The most hands-on task is managing the physical backups—saving files to separate USB sticks and storing the master password safely (e.g., a password manager and/or a deadman switch for inheritance).

In short, ENCRYPTFIRE keeps everything offline, uses standard cryptography, and splits your backup into two useless-by-themselves halves—making cold storage more resilient if you handle the USBs and password properly.

Common Ways People Lose Control

Time, uncertainty, or "I’ll do it later". We’ve all been there. These are the usual traps and how to dodge them.

Leaving coins on an exchange

Exchanges can halt withdrawals, get hacked, or rewrite the rules overnight — and in a crunch, government actions, lawsuits, liquidity squeezes, or sudden KYC/AML reviews can freeze your account.

What can go wrong

Regulatory actions — policy changes, geo-blocks, or directives limit access.
Lawsuits & insolvency — legal proceedings or bankruptcy can lock funds for months.
Liquidity crunch — major market moves → withdrawal queues, limits, or delays.
KYC/AML triggers — “Source of funds?” reviews suspend accounts pending paperwork.

EncryptFire fix

Move to a wallet where you hold the keys.
Create split, offline backups (Seed Map + Seed Codes).
Do a test restore, then duplicate to two separate locations.

“Third-party cold storage” custody

Custodians add counterparty and jurisdiction risk. Policies, pauses, and legal processes can put your assets on someone else’s timeline.

Fine print to know

Pauses/freezes from compliance or court orders.
“Segregated” assets can still face disputes in practice.
Insurance has limits/exclusions; recovery can take months.
Access is by policy, not by private key.

EncryptFire fix

Self-custody with a resilient split—not one metal card.
Store components separately; one file alone is useless.
Plan inheritance: clear, offline path for your heirs.

Other traps that look “safe”

One paper/steel backup — fire, theft, or loss = total loss.
Seed in the cloud — notes, photos, email = account takeover risk.
Yield/“earn” lockups — partner risk can freeze withdrawals.
No inheritance plan — family can’t access funds when it matters.
Device + backup stored together — wallet device and seed in one place = one theft or incident takes both.

EncryptFire fix

Split backups you can duplicate freely without exposing the seedphrase.
All files created offline; nothing stored on our servers.
Deadman-switch–friendly: clear path for your heirs, on your terms.

Dependable By Design

Technically Speaking

✅ AES‑256‑CBC with unique salt and IV — Trusted, tested, audited
✅ 32‑character random passwords — Practically unbreakable by today’s standards
✅ Runs 100% offline — No cloud, no trackers, no phoning home
✅ Fully transparent code — No DRM, no mystery code, you can vet every line of code independently

“If quantum computers ever break AES‑256, the internet collapses well before your encrypted files on USB sticks.”

100% Transparency

✅ Uses proven open-source encryption libraries — no proprietary black boxes
✅ App runs locally in your browser — nothing is ever sent or stored online
✅ Every backup uses a fresh, randomly generated cipher — no repeats, no shortcuts
✅ Memory is cleared on refresh or close — nothing lingers, nothing leaks

“All our logic is visible to the user. No server calls. No storage in-browser. Just tight cryptography, all in plain sight.”

No cloud, no DRM, no bloat

Not everyone runs a node, shards keys with Shamir, or layers multisig. But if you believe “Not your keys, not your crypto,” you already know secure backups are non-negotiable.

EncryptFire was built as a privacy-first, decentralized tool for people who value the same principles as Bitcoin: ownership, security, and autonomy. It avoids centralized infrastructure (cloud), restrictive controls (DRM), and excess complexity (bloat), making it ideal for users who want full control over their digital lives.

Because if you're going to be your own bank, your backups better act like vaults.

In self-custody, transparent and dependable beats complex and opaque. With ENCRYPTFIRE you don’t have to trust — you can verify.

CRYPTO HORROR STORIES

A big banking family, tech mogul, entrepreneur and an IT specialist.

Elon Musk

"I literally own zero cryptocurrency, apart from 0.25 BTC that a friend sent me many years ago. I have no idea where it is." – Elon Musk (2017)

Even the world's most tech-savvy billionaire lost track of his Bitcoin holdings. Without proper backup and redundancy, even small amounts (which can increase in value over time) can be permanently lost.

Matthew Mellon

As an ambassador of Ripple Labs, Matthew Mellon held $1 billion in XRP.
After his death, his family scrambled to recover his fortune.
Stored his digital keys in cold storage, under different people's names—but without proper access planning, his family couldn't retrieve the assets.

Gerald Cotten

Founder of QuadrigaCX, one of Canada's biggest crypto exchanges.
Held $250 million in customer funds—but died unexpectedly with all private keys.
He had joked about storing his keys in a bank deposit box and in a safe in the attic rafters, but no one else had access when he passed.

James Howells

In 2013, IT engineer James Howells accidentally threw away a hard drive containing 8,000 BTC (now worth hundreds of millions).
Despite extensive searches and recovery attempts, his Bitcoin remains lost in a landfill.
This serves as a reminder: Digital assets must be backed up securely, with redundancy and recovery planning.
