Proven on mainnet

Sealed on the public network

A real wallet on Stellar mainnet: opened with a passkey, funded, and spent from, every fee paid by Sembol Cloud, on the audited OpenZeppelin contracts already deployed there. Sembol deploys nothing of its own. 16 September 2026.

The ritual

Thirty seconds,
three gestures

Press

Face ID makes a passkey inside your device's secure chip. It never leaves, it never syncs to a server, and there is nothing to write on paper. That is the whole ceremony.

Seal

Sembol deploys an OpenZeppelin smart account on Stellar and binds it to your passkey. A real contract, on a real chain, owned by you. Creation fees are sponsored, so you start from zero.

Spend

Every payment shows you exactly what moves and asks for your face before it does. Lose the phone, keep the wallet: passkeys sync like passwords, and backup signers recover the rest.

What is written here

Seed phrases lose more people than hackers do. Every entry below removes a reason to quit without giving up ownership.

S-01

Self-custodial, actually

The key lives in the secure enclave and never leaves it. No server copy, no export button to phish.

S-02

Nothing to write down

Passkeys sync through iCloud and Google the way your passwords already do.

S-03

Recovery built in

Backup passkeys, recovery credentials, on-chain spending caps. A smart account, not a fragile keypair.

S-05

Your brand, not ours

One typed theme prop restyles every component. Try the theme builder and take the config with you.

S-06

Open, audited bones

MIT on top of OpenZeppelin's audited contracts and the official Stellar smart-account-kit.

For developers

One import, one seal

One provider and a set of typed hooks give you create, connect, send, signers, recovery, and spending limits. Restyle everything from a single theme prop and ship a wallet in an afternoon. This whole site is the proof.

Questions

Is Sembol self-custodial?

Yes. The wallet is an OpenZeppelin smart account contract on Stellar, owned by a passkey that lives in your device's secure enclave. Sembol never holds keys and cannot move funds.

What happens if I lose my phone?

Passkeys sync through iCloud Keychain or Google Password Manager like your passwords do. You can also add backup passkeys and a recovery credential from the Security page, enforced by the contract on-chain.

Do I need XLM or a browser extension to start?

No. Wallet creation is sponsored by a fee relayer and runs in any modern browser with Face ID, Touch ID, or Windows Hello. On testnet you get free XLM instantly.

Can I use Sembol in my own app?

Yes. Install @sembol/passkey-react from npm: one provider, typed hooks, prebuilt components, and a theme prop that restyles everything to your brand. MIT licensed.

A wallet with your face on it, free test XLM in it, and your first payment out of it. Half a minute, in this browser.
