KALYX
Twelve words.
That is all that stands between you and your money. And all that protects it.
In Kalyx they stay veiled until your finger rests on them. Nobody reads them over your shoulder — not even a screenshot.

Chapter I
How it works
A wallet, not a maze.
64
networks
Bitcoin, Ethereum and its Layer 2s, Solana: 64 networks aggregated into one number, one curve. The balance shows from cache before the network even answers.
Chapter II
Never lose it
Never lose it
There is no “forgot password” button.
Nobody can give your phrase back to you — not even us. So the app helps you not to lose it, in three gestures.

Hold to reveal — like in the app.
1
Write it down, by hand.
During backup the twelve words stay veiled until your finger rests on them. Screenshots are blocked, copy-paste does not exist. A pen, a paper, a drawer.
2
Prove it.
Kalyx asks you for three words, at random. Until you find them, a banner stays on the home screen. A phrase you never re-read is a phrase you do not have.
3
Double it, encrypted.
Export an encrypted file on the device, with a password of your choice. Store it anywhere — a cloud, an e-mail to yourself. Without the password, that file is worthless.
Chapter III
Never get robbed
Never get robbed
Theft does not come by forcing the door. It comes when you open it.
Three scenes Kalyx plays every day, exactly as they are written in the code.
Scene 1 · Address poisoning
The look-alike in your recents.
A scammer sends you dust from an address that starts and ends like your friend’s. One day, you copy it.
Your friend

0x7a3F08bA71e3D5c26F9a4B0e8C7d1A6f3E2b9c2EKalyx compares, and blocks. Not a warning: a wall.
Scene 2 · The signature
What the dApp is really asking for.
A site hands you a contract in hexadecimal. Kalyx simulates it, translates it, and checks the domain with WalletConnect Verify and GoPlus.
An unknown site requests a signature
0xa22cb4650000000000000000000000003f1c9e8b2a7d4f6e05c8b1a93d7e2f6c4b8a1d0e
Danger · “Refuse” by default, hold 2 s to accept
Scene 3 · The stolen phone
The thief has your phone. Not your PIN.
Your phrase is encrypted with AES-256-GCM under a key derived from your PIN with scrypt, then stored in the Keystore or Keychain. Without the PIN, only noise remains. And every mistake costs time:
And if one day you lose the phone: your twelve words, on their paper, recreate everything on another one.

Scene 4 · The whitelist
They know your PIN. Not your patience.
Turn on the whitelist: sends only go to the addresses you chose and to your own accounts. Even with your PIN, a thief cannot change anything within the hour.
A thief in a hurry leaves empty-handed.

Scene 5 · Under duress
Someone forces you to open the app.
Type your duress code: Kalyx opens normally, on a decoy wallet. Your real wallets, contacts and notifications stay invisible — nothing hints that they exist.
Biometrics turn off while it exists: a face would always open the real ones.

All of this runs on your phone . Kalyx has no server that sees your keys, your IP address is never sent to us, no analytics SDK looks over your shoulder.
Chapter IV
The AI copilot
The AI copilot
An AI that explains itself to you, never one that spies on you.
Kalyx has no AI server and holds no key for you. The copilot is optional: you plug in your own provider, and only you pay for what you use.
providers, or a URL of your own
OpenAI, Anthropic (Claude), Gemini, DeepSeek, Groq, OpenRouter, Together, Hugging Face — or any OpenAI-compatible endpoint, at your own address.
Kalyx servers that see your key
Your API key is encrypted on your phone and goes straight to the provider you chose. Kalyx never sees it, never stores it.
markup taken by Kalyx
You pay your provider at its own rate — often with a free tier. Kalyx takes nothing on AI.
by default, until your key
The copilot stays off until you paste an API key. No data leaves without that step.
Before you sign, ask "what will this contract actually do?" — the copilot reads the simulation and answers in one sentence, in your language — the same principle as every signature already translated into plain words.
Switch provider or model anytime, or turn it all off in one tap from settings. BYOK means: your key, your rules, your budget.
Chapter V
Fees, no detours
Fees, no detours
How Kalyx makes a living. In one line.
0.3%
on a swap via LI.FI
EVM and cross-chain. This is Kalyx’s only revenue.
Free wallets often hide their price inside the route of a swap. Here is ours, number by number, as it is written in the code.
- to send, receive, hold€0
Only network fees apply — they go to validators, not to us.
- on a swap via LI.FI0.3%
EVM and cross-chain. This is Kalyx’s only revenue.
- on a TON swap via STON.fi0.3%
Swaps on TON (TON, USD₮, jettons). Same rate as LI.FI.
- on a Solana swap via Jupiter0%
No commission added to the route.
- on Earn0%
Aave, Lido, Rocket Pool, Benqi, Jito, Marinade, Tonstakers: nothing taken on deposit or withdrawal.
- subscription, forever€0
No “pro” tier, no feature behind a paywall.
Before every signature, network fees are shown in your currency, with the possible tiers. If you are short on gas, Kalyx tells you how much — in your currency too, not in gwei.
Card purchases go through MoonPay or Stripe, licensed partners: their separate page handles identity checks itself and never sees your keys. Kalyx adds no commission, and the crypto lands straight on your address. No fiat selling in the app.
Chapter VI
What we want
Why leave the wallet everyone has. A wallet that protects you, and that you understand. No server ever sees a key. Ever. That is not a marketing promise, it is the architecture. Every signature is explained in plain words before the tap — because that is where people get drained. Speed you can feel: the home screen opens from cache, before the network answers. If an element serves neither understanding nor trust, we remove it. Cards, through a licensed partner — isolated, regulated, never mixed with the core. One person, tested code, fifteen languages, and the will to do it right.
