Privacyon Solana.

Solana supports several privacy models: public addresses, private amounts, unlinkable payments, and encrypted computation.

Privacy is a Spectrum.

Privacy is not a single switch. Identity and data visibility can be mixed, giving builders different tools for different products.

AXES
IDENTITY VISIBLE
IDENTITY HIDDEN
DATA · VISIBLE
Pseudonymity
LV. 01

Data is public, but identity is not. Anyone can inspect activity, while the wallet owner decides when to connect it to a real person.

  • This is Solana's default model: every wallet is a public key
  • Standard SPL transfers are visible, but addresses do not carry built-in identity
Anonymity
LV. 02

The transaction may be visible, but the sender-receiver link is broken. Observers can see that activity happened without tracing who paid whom.

  • Solana throughput helps ZK-based anonymity systems run at scale
  • Proof verification can run inside fast settlement windows
  • Protocols like Light Protocol support anonymous state for apps
DATA · HIDDEN
Confidentiality
LV. 03

Participants may be known, but amounts, balances, or transfer details stay private. Observers can still verify that rules were followed.

  • Confidential Token Extensions encrypt transfer amounts and balances with ZK proofs
  • Payroll and business payments can stay private
  • Stablecoin transfers can hide amounts between sender and receiver
Full Privacy
LV. 04

Neither identity nor data is public. Apps compute over protected inputs, then publish proofs or final results on-chain.

  • Projects like Arcium and Inco bring private compute to Solana apps
  • Order flow, positions, and strategies can remain protected
  • Games can keep hidden state without leaving Solana

Design Principles.

01/

Privacy Should Be Programmable

Developers should choose the privacy level their app needs. Payroll, trading, and governance do not all need the same disclosure model.

principle // 01

composable true
scope per-app
opt-in default
02/

Privacy and Compliance Go Together

Privacy can still support controls. ZK proofs and selective disclosure let teams prove facts without publishing raw data.

principle // 02

zk-proof native
audit selective
disclosure opt-in
03/

Performance Matters

Privacy costs compute. Solana's throughput helps make ZK proofs, MPC, and encrypted state practical for live apps.

What Privacy Unlocks.

Privacy is not only about hiding data. It lets apps handle sensitive money, identity, and strategy on-chain.

Private Payments

Send tokens without exposing amounts or balances to the public.

Build with Confidential Tokens

Confidential Token Extensions are live on Solana mainnet. Encrypt balances, hide transfer amounts, and verify with ZK proofs at the protocol level.
