Cloak is a part of Solana's privacy layer and is meant to be used by people who don't want the entire world seeing what they do with their finances. Nobody wants to be watched with every action they make on chain neing public for all to see, Cloak enables you to keep your life private, Anonymous the way it should be, and Cryptocurrency the way it was meant to be.
Cloak enables confidential transfers using zero-knowledge proofs (zk-SNARKs) and Merkle-tree commitments.
Users can shield and unshield SOL — moving between public and private states without leaving any traceable link.
You can even send privately to another user anywhere on solana, with the recipient receiving funds from "the void" — never knowing who sent it to them to ensure complete privacy.
The Void Pool is the beating heart of Cloak — a shared vault of anonymized funds. Your SOL enters the pool, mixes with everyone else's, and comes out untraceable.
Think of it as a cryptographic masquerade:
Cloak is part of Solana's privacy layer — built for people who don't want to be tracked. No one likes a stalker. Cloak makes sure you don't have one.
We give you a way to send and receive SOL without leaving a public trace that ties everything back to your wallet. It's fast, decentralized, and invisible — the way privacy should feel.
If you don't want your financial activity mapped by data brokers, state agencies, or scammers, Cloak acts as a private intermediary between your wallet and the chain.
With almost no setup and just a few extra seconds of delay, you can protect yourself from:
Cloak lets you blend into the flow instead of standing out.
Cloak is designed to stay true to what crypto was meant to be — controlled by the people.
When you deposit into the Cloak pool, your SOL is automatically staked via liquid staking, earning APY while it sits anonymized.
That means you'll often withdraw more than you deposited, even while staying completely private.
*minus gas fees
*Cloak does not provide security guarantees for modified relayers.
From the outside: "Someone deposited 10 SOL."
Not visible: who, when, or which deposit is theirs.
On-chain view: "Someone withdrew 7 SOL from the Void Pool."
Invisible: that it was you, when, or how much you still hold.
Deposits are hashed — irreversible and unlinkable.
Every transaction looks identical: 2 inputs, 2 outputs.
Prove validity without revealing identity or history.
Each deposit is locked to your key only.
Prevents reuse — every spent note is permanently marked.
