Encrypt Brings FHE to Solana for Private Capital Markets

Encrypt launches fully homomorphic encryption on Solana, letting applications compute on encrypted data without decryption, targeting confidential DeFi capital markets.

Encrypt has announced it is coming to Solana. The protocol introduces fully homomorphic encryption directly into the Solana Virtual Machine, letting smart contracts compute on encrypted inputs and produce encrypted outputs without the underlying data ever being exposed. The project is calling this infrastructure the foundation for Encrypted Capital Markets.

Transparent blockchains have a long-standing structural problem. As @encrypt_xyz posted on X, every order placed on a public chain is visible before it executes, every position is open to the entire market, and every strategy is susceptible to front-running. That is not a bug in a single protocol. It is how transparent blockchains are built. Finance, the team argues, does not operate this way.

DeFi’s Transparency Problem Has a New Answer

FHE changes this at the execution layer. According to @encrypt_xyz on X, a Solana program can take encrypted inputs, run logic on them, and return encrypted outputs. Validators do not see the data. MEV searchers do not see it. No one does. The computation happens entirely on ciphertext.

The team addressed competing privacy approaches in a follow-up post. As @encrypt_xyz stated on X, zero-knowledge proofs prove something happened but do not hide shared state. Trusted execution environments trust hardware manufacturers. Generic multi-party computation trades composability for performance. FHE, the team argues, is the only method supporting arbitrary computation on encrypted shared state while keeping decentralization and composability intact. For financial markets, that distinction matters.

This is part of a broader shift in how builders are thinking about Solana as infrastructure for institutions. Confidentiality has long been the barrier institutions cite most often. Encrypt’s arrival directly targets that gap.

What Builders Can Actually Construct Now

The application layer becomes substantially different with FHE running inside the SVM. As outlined in the @encrypt_xyz thread on X, orderbooks can keep orders encrypted until matching occurs. Auctions can keep bids sealed until resolution. Lending markets can keep positions private. Prediction markets can operate without participants signaling positions or herding behavior. All of it composable. All of it on Solana.

David Lachmish, Co-Founder of Encrypt, said Solana has already proven that markets can move onchain. The next step, he said, is cryptographic guarantees for private state on a public blockchain. FHE, he said, makes confidentiality a native building block for composable applications on Solana.

The implications are not limited to developers. As @encrypt_xyz noted on X, users would no longer have their financial behavior permanently visible to the public. Developers gain access to application categories that were previously not buildable. For institutions, the team claims the biggest barrier to onchain adoption is now addressable.

This connects directly to a conversation about why DeFi exists on public chains at all. Open, neutral, permissionless systems still need to give users some degree of operational privacy to compete with traditional finance.

Built on Ika, Backed by FHE Research

Encrypt is built by the team behind Ika and uses Ika as infrastructure on Solana. According to @encrypt_xyz on X, the system is grounded in state-of-the-art FHE research including REFHE and novel Threshold FHE implementations. That research base is what the team says makes the approach fast, decentralized, and composable simultaneously, not a trade-off between those properties.

Encrypt is targeting Solana devnet in early Q2 2025. Mainnet deployment is planned later in the year, per the project’s official announcement via Decrypt.

As @encrypt_xyz first announced on X, this is fully homomorphic encryption for the Solana Virtual Machine. Applications that compute on encrypted data without decrypting it. Encrypted Capital Markets. The sentence structure was deliberate. So is the timing.
