Load. Redeem. Privately.
Send private payments on Solana. Share a claim link; recipients withdraw via stealth addresses so the on-chain trail breaks at deposit.






One platform, three private flows
Whether you're sending a tip, paying a team, or buying a virtual card — the on-chain trail breaks the moment funds enter Umbra.
Send Payments
Deposit SOL, USDC, or USDT and share the claim link. No address required. Recipients claim with any wallet — or just an email.
Create a linkRun Payroll
Upload a CSV, sign one bulk deposit, mint a private claim link per employee. Refund anything left unclaimed.
Open dashboardVirtual Cards
Convert encrypted balance into a Visa or Mastercard. Spend anywhere, no KYC, no on-chain trail back to the deposit.
Buy a cardHow it works
Three steps. No address swaps, no awkward setup.
Deposit into Umbra
Funds become an encrypted UTXO bound to a one-time keypair. Amount and destination are ciphertext on-chain.
Share the link
The keypair lives in the URL hash. Send it via text, email, QR, or whatever. Only link holders can claim.
Claim via stealth address
Funds route to a fresh address — no on-chain edge to the deposit. Relayer pays gas, so recipients need zero SOL.
Built for actually using
Privacy, ergonomics, and recovery — fused into one product.
Stealth-address privacy
Funds withdraw to a fresh address derived from the recipient's viewing key. No on-chain edge connects the deposit to the claim.
Run payroll privately
Upload a CSV, sign one bulk deposit, mint a self-claimable link per employee. Refund anything left unclaimed.
Gasless claims
Recipients claim with zero SOL. The relayer covers transaction fees.
