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.

Lost every passkey? Recover with your kit
This browser cannot use passkeys. Open KOIN Vault in a current version of Chrome, Edge or Safari, or use your recovery kit.
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.

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.
New passkey captured ✓ — now confirm with your current passkey to register it on-chain.
Save your recovery kit as a .txt file. If the download didn't start, use the button below. Keep the file safe and offline — anyone holding it controls the account. It only works after you activate it.
This adds another kit for the same wallet. Existing kits stay active, even if their files were deleted or destroyed.

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.
Stay signed in until you sign out. Your passkey still approves every transaction.
