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.

Send Payments Virtual Cards

Live on Solana devnet

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.

Virtual Cards

Convert encrypted balance into a Visa or Mastercard. Spend anywhere, no KYC, no on-chain trail back to the deposit.

How 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.

New

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.

SOL · USDC · USDT

Multi-token on Solana devnet. Stablecoin claims auto-subsidize SOL gas.

No wallet required
