Zero-Knowledge Privacy Protocol
Confidential transactions on Solana
Privacy infrastructure for Solana
ShadowLayer is a zero-knowledge privacy protocol built natively on Solana. By leveraging Groth16 zkSNARKs and Pedersen Commitments, it enables fully confidential transactions where sender identity, recipient identity, and transfer amounts remain cryptographically shielded -- without bridges, sidechains, or off-chain sequencers.
Every shielded transaction produces a single compact proof that is verified entirely on-chain. The protocol requires no trusted setup ceremonies and introduces no additional trust assumptions beyond Solana's consensus itself, delivering pure cryptographic certainty at network speed.
Privacy Guarantees
Transaction Confidentiality
Amounts and participants are shielded via Pedersen Commitments with zero-knowledge range proofs. Value conservation is verified homomorphically, ensuring no amounts are ever revealed while maintaining provable correctness across the entire transaction graph.
Sender Anonymity
Transaction graph analysis is prevented through cryptographic mixing with Poseidon hash functions. The sender is hidden within a Merkle-based anonymity set, making them computationally indistinguishable from every other participant in the shielded pool.
Verifiable Compliance
Selective disclosure enables regulatory compliance without compromising privacy. Authorized auditors can verify specific transaction properties through dedicated viewing keys, while the broader network remains unable to observe any confidential details.
How It Works
Deposit
Assets enter the shielded pool via a deposit transaction. A commitment is generated using Pedersen Commitments.
Shield
The protocol generates a Groth16 zkSNARK proof, creating a shielded state that hides amount and sender.
Transact
Shielded transfers occur within the pool. Each transaction produces a new proof without revealing details.
Withdraw
Assets exit the pool with a withdrawal proof. Only the recipient knows the amount and source.
Technology
Cryptographic Primitives
Every component of the ZK stack is selected for security, efficiency, and native Solana compatibility. The combination of Groth16 proofs, Pedersen commitments, and Poseidon hashing delivers constant-size proofs with minimal on-chain verification cost — no bridges, no separate layers, no compromises.
