Private Transfers
on Solana
Send SOL without linking wallets. No direct on-chain connection between sender and receiver. True financial privacy.
How It Works
Three simple steps to private transfers
Commit Funds
Deposit SOL into a neutral vault PDA with a secret hash. Your funds are securely locked until claimed or refunded.
Share Private Link
Generate a magic link with the deposit details. Share it with your recipient through any secure channel.
Claim with Secret
The recipient proves knowledge of the secret code and receives the SOL directly to their wallet.
The Privacy Problem
Traditional transfers expose your financial relationships

Privacy by Design
Built from the ground up for unlinkability
No Direct Transfers
Sender and receiver never interact directly on-chain. All funds flow through neutral vault PDAs.
No On-Chain Recipient
The recipient is never defined on-chain. Only the hash of a secret is stored.
Relationship Privacy
No direct on-chain link between sender and receiver. The intended recipient is never stored on-chain.
SHA-256 Verification
Cryptographic proof ensures only the intended recipient can claim the funds.
Time-Locked Refunds
Unclaimed deposits become refundable after expiration. Sender can trigger refund at any time after expiration.
Open Source
Fully auditable smart contracts and frontend. Trust through transparency.
