From pseudonymous wallets to fully encrypted computation, Solana supports every level of privacy.
Most discussions about privacy assume only two modes: public or private. But real systems are more nuanced. Privacy can be understood across two axes, identity visibility and data visibility, creating four distinct models.
Data is public, but identity is not. A pseudonymous system lets anyone inspect transactions, balances, and history, but none of it is linked to a real-world person unless the owner chooses to reveal themselves.
The transaction itself may be visible, but the link between sender and receiver is cryptographically broken. No observer can determine who paid whom. This goes beyond pseudonymity: even if you can see that a transfer happened, you cannot trace it back to a specific address or person.
The participants may be known, but the contents of their transactions are hidden. Amounts, balances, and transfer data are encrypted so that only the parties involved can read them. Observers can verify that rules were followed without seeing the underlying values.
Neither identity nor data is visible. Computation happens on encrypted inputs inside secure environments. Only proofs or final results are published on-chain. The chain verifies correctness without ever seeing the underlying data.
Developers should be able to choose the right privacy level for their application. A payroll system has different requirements than a public governance vote. Privacy primitives should be composable building blocks, not all-or-nothing switches.
Privacy does not mean avoiding regulation. With zero-knowledge proofs, users can prove solvency without exposing balances, verify eligibility without revealing identity, and satisfy audit requirements without making data public. Compliant privacy is not a compromise, it is better design.
Privacy technologies are often computationally heavy. ZK proof generation and verification, homomorphic encryption, and secure multi-party computation all demand significant resources. Solana's throughput makes these primitives usable in real-world applications.

Privacy is not just about hiding data. It enables entirely new categories of applications that cannot exist on transparent chains.
Send and receive tokens without exposing amounts or balances to the public. Essential for salary payments, business transactions, and personal transfers.
Execute trades without revealing strategy, position size, or timing to front-runners and MEV bots. Confidential order flow protects both retail and institutional traders.
Pay employees and contractors on-chain without making compensation data public. Employers retain audit capability while keeping individual amounts private.
Vote on proposals without revealing individual choices until results are finalized. Prevents vote-buying, social pressure, and strategic last-minute swings.
Prove attributes like age, citizenship, or credential ownership without revealing the underlying data. Zero-knowledge identity enables compliant privacy.
Autonomous agents that transact, hold assets, and execute strategies without leaking proprietary logic or user data to on-chain observers.
Confidential Token Extensions are live on Solana mainnet. Encrypt balances, hide transfer amounts, and verify with zero-knowledge proofs, all at the protocol level. No external dependencies required.
