TL; DR
- On-chain privacy is a dominant story for 2026, with apps seeing over $530 million in weekly volume.
- Hush Protocol launches a quantum-resistant privacy layer on Solana that generates revenue via staking.
- The CEO cites institutional adoption as the next big catalyst for privacy innovation on Solana.
Onchain privacy is quickly establishing itself as one of the dominant crypto stories in 2026. DeFi users flocking to privacy-protecting applications in record volumes, with leading onchain shielding apps reaching their peak $530 million in weekly volume in January.
Launched by Zenrock, Silence protocol becomes the latest application to join Solana’s booming privacy sector. The platform offers a quantum-resistant shielding layer that produces returns.
Touted as one Zcash-inspired privacy layer on Solana, Silence protocol allows DeFi users to protect their onchain transactions from prying eyes. However, Zenrock claims that Hush Protocol goes beyond a simple mixer and claims that it does shielded computer layer can theoretically power any Solana application in a fully Turing-complete virtual machine.
New features include a compliant design in which geo-blocking measures about sanctioned regions, localized client-side evidence, and built-in efficiency $SOL deposits. Each $SOL poured in Silence protocol is automatically converted to $jitoSOLwhere the betting proceeds and MEV are passively distributed among users.
Every onchain action you’ve ever performed is public.
Transactions. Wallets. Claims. Everything.
That shouldn’t be the standard.
Meet Hush – the privacy layer for @solana.

At the launch, Silence protocol offers a simple set of features including deposits, transfers and withdrawals, with additional features expected in the future.
Institutional adoption as the next catalyst
In an exclusive statement shared with SolanaFloor, CEO of Zenrock argues that institutional adoption is the next big catalyst for innovation in Solana’s privacy scene. Although Solana-based privacy applications are currently limited to basic transfers, Aditya Dave remains convinced that the sector is still in its infancy.
The co-founder of Zenrock expects that privacy layers such as Hush Protocol will enable the deployment of more powerful DeFi primitives in the shielded economy. “If you are optimistic about institutionalization, you are also indirectly optimistic about privacy. The onchain economy will create a reflexive privacy loop by 2026: TradFi products require privacy, privacy adoption amplifies network effects, enabling more advanced products. RWAs, DeFi vaults, trading, AI agents – they all need a layer of privacy. Hush builds that privacy layer on Solana” said Dave.
Silence protocol the documentation shows that deposits are free and transfers are charged a fee 0.01 $jitoSOL and a 0.5% fee charged for withdrawals from the shielded pool.
The launch of Hush Protocol comes a day later Arciuman infrastructure provider for many emerging privacy apps, has announced its mainnet alpha. Arcium’s launch was interrupted by the beta rollout of Umbraa rival privacy-preserving DeFi layer that leverages Arcium’s tech stack.
At the time of writing, market leader Privacy money still holds the majority of Solana’s shielded transfer volume, with more than $220 million in cumulative volume.
