cSOL: Confidential Solana Token Documentation
Overview
cSOL (Confidential Solana) is a privacy-preserving token that enables confidential transactions on the Solana blockchain. Built using Solana's Token-2022 program with confidential transfer extensions, cSOL allows users to transact with complete privacy while maintaining the speed and efficiency of the Solana network.
What is cSOL?
cSOL is a 1:1 representation of SOL that provides:
Complete Transaction Privacy: Transfer amounts and balances are encrypted and hidden from public view
Zero-Knowledge Proofs: Transactions are validated using cryptographic proofs without revealing sensitive information
Solana Speed: Maintains Solana's fast transaction times and low fees
Ecosystem Integration: Seamlessly works with existing Solana infrastructure
How It Works
Bridge Mechanism
The zkVoid bridge enables users to convert regular SOL into cSOL:
Deposit SOL: Users deposit regular SOL into the bridge contract
Mint cSOL: The bridge mints an equivalent amount of cSOL (minus fees)
Confidential Transfers: Users can now transact privately using cSOL
Withdraw: Users can convert cSOL back to regular SOL at any time
Bridge Fee Structure
Bridge Fee: 0.1% on all SOL → cSOL conversions
Fee Purpose: Supports the $VOID ecosystem development and maintenance
No Withdrawal Fees: Converting cSOL back to SOL is free (only network fees apply)
Privacy Features
Hidden Balances
Your cSOL balance is encrypted and only visible to you
Other users cannot see how much cSOL you hold
Blockchain explorers show encrypted data instead of actual amounts
Confidential Transfers
Transfer amounts are completely hidden from public view
Only the sender and receiver know the transaction amount
Transaction history shows encrypted values to external observers
Zero-Knowledge Validation
Transactions are validated using zero-knowledge proofs
Proves transaction validity without revealing amounts
Maintains network security while preserving privacy

Frequently Asked Questions
Is cSOL backed by real SOL?
Yes, every cSOL token is backed 1:1 by SOL held in the bridge contract. You can always redeem cSOL for SOL.
Can I see other people's cSOL balances?
No, cSOL balances are encrypted and only visible to the account owner. This is the core privacy feature.
What happens if I lose my wallet?
If you lose access to your wallet, you lose access to your cSOL. Always backup your wallet securely.
Are cSOL transactions completely anonymous?
Transaction amounts and balances are hidden, but wallet addresses and transaction timing are still visible on-chain.
Can I use cSOL in other DeFi protocols?
cSOL can be used in any protocol that supports Token-2022 tokens with confidential transfer extensions.
How do I verify my cSOL balance?
Use the zkVoid wallet to decrypt and view your confidential balance. Only you can see this information.
