Smart Pay Docs

Private SOL transfers with a cleaner, simpler user flow.

Smart Pay helps users send SOL privately on Solana using wallet-based encryption and shielded transfer flows powered by Privacy Cash. The app is non-custodial, direct, and built for private transfers without adding account friction.

How privacy works

Funds are deposited into a shielded pool and later withdrawn privately, reducing the on-chain link between sender and recipient.

Launch features

Single private sends, multi-send, payment links, Solana wallet support, and signature-derived encryption are ready now.

Non-custodial by default

Users stay in control of their wallet. Smart Pay does not take custody of keys or require a separate account system.

Ready at launch

Private Send

Send SOL with sender privacy preserved through shielded deposit and withdrawal flows.

Multi Send

Split one amount across up to 5 recipients and keep transfers unlinkable.

Payment Links

Create shareable links so anyone can send you SOL privately without seeing your wallet in plain text.

Wallet-based Encryption

Initialize encryption from your wallet signature without creating extra passwords or accounts.

Quick start

  1. 1. Connect Phantom or Solflare.
  2. 2. Initialize encryption by signing once with your wallet.
  3. 3. Enter an amount and one or more recipients.
  4. 4. Submit the private transfer and monitor the transaction hashes.
Payment links follow the same private flow, but let the payer initiate the transfer from a shareable URL.
Roadmap

Coming Soon

Private SPL token transfers, address book support, encrypted local transaction history, QR code payments, and a more polished mobile flow.

Planned Updates

Recurring private payments, multi-token multi-send, stealth addresses, webhook notifications, and an SDK/API for dApp integrations.

Future Vision

Private NFT transfers, optional compliance view keys, and privacy-native DAO payment tooling.
