A simple and private passkey wallet on Solana. No seed phrases. No gas. Just your face.
Live in private mainnet beta. Dark by default. Built for people who get paid in crypto but don't want to live in crypto: receive, hold, send, and cash out, without ever learning what a seed phrase is.
Android APK (request access via the waitlist)
Fresh captures from the current dark-mode mainnet build are being added. The earlier light-mode devnet shots were removed because they no longer reflect the app.
- Passkey login. FaceID, fingerprint, or device biometrics through LazorKit. No seed phrase, ever.
- No gas. Sends and swaps are sponsored through the Kora paymaster, so you don't need to hold SOL just to pay fees.
- Multi-token sends. Send SOL, USDC, and SEED from one place, each with its own balance and max.
- Send privately. Flip one switch before you send and the amount stays between you and the person you're paying, powered by the Umbra SDK.
- Stealth addresses. One-time receiving addresses so incoming payments aren't tied to your main wallet.
- Burner wallets. Disposable, isolated wallets with no on-chain link to your identity, now with SPL token support.
- Jupiter swaps. Best-price token swaps with a live token picker, gas-free.
- Private mode. Hide balances behind a tap, biometric auth to reveal.
- Wallet rename. Name your wallet, persisted per passkey.

npm run android # or: npm run iosSeedless is a product, not a library, so this is a high-level look at how it works rather than a build guide.
- Identity. Every user is a LazorKit smart wallet controlled by a WebAuthn passkey held in the device Secure Enclave or Android Keystore. There is no seed phrase to store, leak, or recover.
- No gas. Transactions are relayed through the Kora paymaster, which sponsors the network fee, so a user never needs SOL just to move money. App-level rate limiting protects the relayer.
- Private sends. The Umbra SDK shields the transfer amount so it stays between the sender and the person being paid.
- Swaps. Jupiter routes best-price swaps, executed gas-free through the same relayer path.
- Cross-chain (in progress). The PasskeyDWalletController program verifies a passkey signature on-chain (secp256r1 precompile introspection, mirroring SIMD-0048) before authorizing an Ika MPC dWallet to sign EVM transactions.
- Infrastructure. Alchemy is the primary mainnet RPC, with Helius serving websockets.
The design goal is invisibility. The crypto is the engine, not the dashboard.
React Native (Expo) and TypeScript on the client. LazorKit for passkey smart wallets, Kora for gasless transactions, Umbra for private sends, Jupiter for swaps, and Solana web3.js throughout.
- Bags Hackathon winner (top 5).
- 2nd place, Umbra Colosseum Frontier sidetrack for bringing private payments to the wallet layer.
- Placed in the Encrypt/Ika Frontier sidetrack with PasskeyDWalletController, an on-chain authority that lets a passkey control an Ika MPC dWallet.
- Cash out to your bank. Crypto to local currency offramp, the retention piece that makes this real money for everyday users.
- Cross-chain signing via Ika. Sign EVM transactions from your passkey through the PasskeyDWalletController program (live on devnet), wiring into the app for mainnet.
- Multi-token private send. Extend private sends beyond SOL to USDC and other tokens.
