What can I do here? +

Connect a wallet, inspect public balances and activity, look up transaction status, and check token-account readiness. You can export a transfer plan; no transaction is signed or sent. Private transfers require confidential keys and a proof engine, which are not connected here. Solana Confidential Balances can encrypt supported token amounts and balances. Addresses, owners, and the mint remain public; an issuer may configure an auditor.

Privacy on Solana
Public blockchains reveal transaction activity. Confidential Balances can protect supported token amounts and balances, while addresses and relationships remain visible. Understanding those boundaries is the first step toward informed privacy choices.

Private Possibilities.

Privacy at the Protocol Layer.

Public blockchains make activity visible by default. Wallet histories, balances, and connections can tell a story you never chose to share.

We exploreexplainclarify what privacy on Solana can protect.

Our vision brings together confidential balances, clear disclosure choices, and the power of decentralization, with a clear understanding of what remains public.

The goal: prove what matters without revealing everything behind it.
The goal: make disclosure choices and auditor access explicit.
Confidential amounts where supported. Clear visibility into public transaction metadata.
Keep supported token amounts encrypted while recognizing that addresses and transaction relationships remain public.

Private by Default

Verification often reveals far more information than an interaction needs.
A wallet address can become a map of your activity and relationships.
Standard token transfers expose amounts, accounts, and the mint.
Balances, transfers, and connections remain visible long after the interaction ends.

It Starts With You. We envision a Solana ecosystem where privacy belongs to every participant, and disclosure is an intentional act rather than a default setting.

Every interaction should be designed around choice. Different contexts deserve different boundaries. We seek no unnecessary exposure, only the information that matters.

A useful proof should reveal what is needed and leave the rest private.

PENUM

At PENUM, trust is intentional, collaboration is open, and privacy is not optional but foundational.

This is a vision for a privacy protocol on Solana, built around participation, verification, and individual choice.
