Your wallet is
your fingerprint
One scan deploys a real smart account on Koinos — an on-chain contract whose only key is your passkey (face, fingerprint, or device PIN). The chain itself verifies every action against your biometrics, Veive-protocol style. No password, no seed phrase, no fees — and no key that anyone, including us, could steal.
Made your account on another device? Open it with a synced passkey
Lost every passkey? Recover with your kit
This browser has no biometric passkey support — try a phone, or a browser with Face ID / fingerprint / Windows Hello.
Demo mode — no chain connected yet; the passkey flow is real, transactions simulate.
Paste the contents of your recovery kit file
(koinos-recovery-kit-….txt). Its key signs you in and can register a brand-new
passkey — no old passkey needed.
Held by the app's funding key until it lands as KOIN. Tap a row to convert.
Buy KOIN Simulated
Convert ETH, USDC, USDT or SOL you already hold — from any wallet or exchange — into KOIN. One passkey tap lands it.
You need ETH, USDC, USDT or SOL in another wallet or exchange first. This account gets its own Ethereum and Solana deposit addresses; whatever you send there is converted to KOIN here.
Tap the address to copy. ETH, USDC or USDT.
Tap the address to copy. SOL only — it is converted to KOIN through Wormhole and Vortex.
Waiting for a deposit — balances appear here within a minute of confirming on Ethereum.
A conversion is in progress — see step 3.
Once a conversion starts, its progress and the landing button appear here.
Your passkey signs the Koinos-side step only. Fee: free.
Quotes are live; the best route is marked.

Checking your keys…
Reading the sign-in methods registered on your account.
One passkey is one point of failure — if its account (Google / Apple) is ever lost, so is the wallet. Add a second passkey from another device, or download a recovery kit you keep offline.
✓ A recovery kit is active for this account — the file you saved opens it all by itself.
New passkey captured ✓ — now confirm with your current passkey to register it on-chain.
Save this file somewhere safe and offline — it just downloaded, and it's shown below in case you'd rather copy it by hand. Anyone holding it controls the account. It does nothing until you activate it.
On iPhone: tap Share, then Add to Home Screen. It opens full-screen like an app.
Add this wallet to your home screen from your browser's menu to open it like an app.
✓ Installed — you are using the home-screen app.
✓ Works offline — the app shell is saved on this device. Balances still need a connection.
How this account works
Your account is an on-chain contract (Veive protocol); every key on it — passkeys and the recovery kit alike — is a registered credential the blockchain checks itself. Passkeys sync through iCloud Keychain / Google Password Manager; the recovery kit is your manual, offline fallback. Any one of them signs; losing one loses nothing while another remains.
Your account stays on-chain. Your passkey opens it again.
