One app · Your identity · Your money · Your messages

They built the internet to own you.
We built Vaultr to give you back.

Every message you send lives on someone else’s server. Every dollar you hold sits in someone else’s custody. Vaultr is the first app built on a single, stubborn idea: you should own everything — and no one, not a government, not a corporation, not a thief with a gun, should be able to take it.

There is a problem hiding in plain sight

You think you own your money. You think your conversations are private. You think your identity is yours.

You don’t. They aren’t. It isn’t.

For the first time in the history of money and communication, there is an answer. Not a patch. Not a setting. A different foundation. This is Vaultr.

Coercion resistance

One password opens your vault.
A different one opens a lie.

Every other vault on earth breaks the moment someone grabs your wrist and says “unlock it.” Vaultr gives you a third option: show them exactly what they want to see — while your real life stays invisible.

••••••••••••

Pick a slot, then unlock. Same gesture. Wildly different truth.

Vault locked

Awaiting password

// system truth — invisible to the coercer

Select a slot and unlock to see what Vaultr actually does.

Decoy

Plausible deniability

A complete, convincing fake profile — display name, contacts, believable balances, normal settings. They unlock it and walk away satisfied. Your real vault never blinks.

Duress

Silent distress

Returns a perfect success. Fires an invisible alert to your guardians. Generates no banner, no sound, no error. The coercer never knows help is already on the way.

Destruct

The nuclear option

Wipes every encrypted slot and key in one operation — and still returns a normal success. They forced you to open a vault. They’re looking at ash.

Your money, your keys, your rules

The smart wallet that rewrites the rules

The history of crypto is seed phrases on paper and billions lost forever. That was never self-custody. That was a trap with extra steps. Vaultr is built on ERC-4337 account abstraction — your wallet is a programmable smart contract, not a fragile secret.

No seed phrase to lose

Your wallet is a smart contract identified by cryptographic math — not a slip of paper you can burn, soak, or forget.

Receive before you deploy

Counterfactual addresses exist before they’re on-chain. Get paid before you’ve spent a cent on gas.

Gas, sponsored

Vaultr can pay your gas. Transact without ever holding the native token. Pay fees in any coin you like.

Batched & atomic

Many operations, one signature, one transaction. It all happens, or none of it does.

Vaultr smart wallet showing multi-chain balances

The server never holds your keys

Shamir’s Secret Sharing over GF(256) splits your master key into three — device, server, recovery. Any two reconstruct it. Hack our servers? One share. Useless.

2-of-3 · no single point of theft

Independent transaction 2FA

Every send is gated by a 64-byte one-time challenge, a one-use JWT consumed atomically in Redis, OTP or biometric. Steal the session — you still can’t move a cent.

30s TTL · replay-proof

Fees with no fine print

0.10% Vaultr-to-Vaultr. 0.25% external. All math in BigInt — no rounding tricks. Hold or stake BMZ and pay up to 90% less.

Blockmaze — Vaultr’s own chain

We didn’t just build on a blockchain. We built one.

Blockmaze is Vaultr’s native Layer 0 — fully EVM-compatible, so every Ethereum tool works out of the box. ~2-second blocks. ERC-4337 from day one. BMZ is the native gas token and the key to the whole economy.

Vaultr encrypted chat with in-conversation payment

Messaging that cannot be compromised

Every platform. One encrypted inbox.

Built on Matrix — the open protocol no single company controls. Through bridges, Vaultr becomes your universal inbox: Telegram, WhatsApp, Signal, XMTP. You reply from Vaultr; it reaches them on their app. They never have to change a thing.

▸End-to-end by default. Not a toggle, not a paywall. Even a subpoena of our servers yields ciphertext.
▸Send money inside a message. Request an amount, on any chain; they claim it with a code. Escrow on-chain, fee shown before a cent moves.
▸Anti-spam by economics. Unknown senders post a deposit. Scammers pay to spam you; the honest get it back. Market design, not moderation.

Never lose access. Ever.

Lose your phone. Keep everything.

The oldest fear in self-custody had one brutal answer: you lose it all, forever. Vaultr has three safety nets so no honest user ever has to fear that again.

01 — SOCIAL RECOVERY

Trusted humans, not passwords

Nominate guardians — spouse, lawyer, best friend. 2 of 3 approve, you’re back in. Every step push-notified and written to an immutable audit trail.

02 — CLOUD BACKUP

Encrypted snapshots

End-to-end encrypted before it ever leaves your device, SHA-256 integrity-verified, restorable any time, and deletable on demand. Your data, your control.

03 — DEVICE MIGRATION

Move everything, atomically

A time-limited, replay-proof transfer token moves your entire vault to a new phone. Everything moves, or nothing does. No interception, no half-states.

Identity, reimagined

You are not one person. Your app shouldn’t be either.

You’re a professional and a parent. A public figure and a private citizen. Each vault slot unlocks an entirely separate profile — its own name, wallets, contacts, messaging identity. Switch with one authenticated tap. Your worlds never bleed into each other.

And when someone demands to see “your wallet”? You show them a decoy. Your real profile never appears. This is identity sovereignty — the right to choose which face the world sees.

Bulletproof authentication

Security isn’t a feature here. It’s the product.

Passkeys / FIDO2

The full WebAuthn spec — unphishable, unforgeable hardware assertions with replay-proof counters. No password to steal.

Face authentication

A 128-dimension descriptor is computed on your device. We store a SHA-256 hash of it — not your face, not your photo.

OTP, done right

SendGrid email + Twilio SMS. Six digits, timing-safe comparison, 5 attempts, then a hard lock.

Immutable audit trail

Every login, every device, every key event — written to an indelible record you can read and no one can rewrite.

The Vaultr Card

Coming soon

Spend your crypto anywhere on earth.

The last barrier between crypto and the real world is simple: you can’t buy coffee with it. We’re removing it. Virtual and physical Visa/Mastercard, funded by your self-custodied balance. The merchant gets fiat. You stay in control — freeze, limit, and unfreeze in real time, from the app, with your face.

// Honest status: the architecture and compliance rails are being built. Cards are not live yet.

The platform

Build on the privacy-first stack

The Vaultr SDK opens the whole stack to developers — wallet, vault, messaging, payments, notifications — behind documented, tiered APIs with real-time usage dashboards and webhook subscriptions for the events that matter.
