Encifher

Encifher is a privacy-preserving DeFi middleware built on Solana that enables confidential token swaps and transfers using fully homomorphic encryption (FHE). Originally launched at encifher.io, the project has since rebranded and now operates as Encrypt at encrypt.trade, while maintaining its @encifherio social presence and documentation at docs.encifher.io.

Core Mechanism

Encifher's privacy engine runs through off-chain Privacy Enhancing Technology (PET) co-processors that perform encrypted computations alongside Solana's public ledger. When a user sends or swaps tokens, the process follows three steps:

1. User inputs are encrypted client-side and dispatched to co-processors, with only cryptographic pointers stored on Solana.
2. When computations on encrypted values are needed, both operands are sent to the co-processor rather than exposed on-chain.
3. Results are written back to Solana accounts, creating private shared state that only authorized parties can read.

This architecture means protocol interactions remain publicly visible on Solana while specifics such as balances, transfer amounts, and swap routes stay encrypted. The encryption combines threshold ElGamal encryption, which requires multiple cooperating parties to decrypt any value, with zero-knowledge proofs that validate transaction correctness without revealing underlying data.

To sever the link between successive transactions, Encifher assigns ephemeral accounts that exist for a single transaction lifecycle. Once the transaction completes the account is discarded, making address-reuse analysis and blockchain-based activity tracking ineffective.

Key Products

Encrypted SPL Tokens (eTokens)

Standard Solana tokens wrapped inside Encifher's privacy engine behave identically to regular SPL tokens but hide balances and transfer details from the public ledger. Wrapping and swapping are deliberately separated into distinct workflow steps to prevent timing-correlation attacks that could link a user's wrap transaction to their subsequent swap.

eZEC

Launched in October 2025 alongside Zcash's arrival on Solana via the Zolana bridge, eZEC is an encrypted re-wrapping of ZEC that restores Zcash-level privacy on Solana. Bridged ZEC arrives as a plain SPL token with no privacy protections, meaning balances and transaction amounts are fully visible on-chain. Encifher re-wraps it into eZEC, storing balance ciphertexts off-chain in a secure data availability layer while Solana holds only cryptographic pointers. Users can trade eZEC on Jupiter while keeping positions hidden from outside observers.

Private Swaps on Jupiter

Encifher integrates directly with Jupiter, Solana's leading DEX aggregator. Users can swap encrypted tokens while keeping balances, routes, and trade intent encrypted throughout execution. Due to the computational overhead inherent in FHE, processing takes approximately 20 seconds per swap, a known trade-off with the current generation of homomorphic encryption technology. Hardware wallet support is provided through Ledger paired with Phantom and Trezor paired with Backpack.

Middleware Architecture

Beyond its consumer-facing app, Encifher is designed as a plug-and-play modular middleware that DeFi protocols can adopt by updating only their interaction layer, leaving existing on-chain programs unchanged. This means privacy can be added to a protocol without new smart contract migrations or fresh security audits of core logic.

Compliance considerations are embedded in the middleware design from the outset. Threshold decryption ensures that designated parties such as regulatory compliance monitors can access encrypted balances when legitimately required, while unauthorized observers cannot. Encrypted token balances are also protected when they reach zero, preventing information leakage from empty-account states.

Team and Backing

Encifher is built by Rize Labs (GitHub: github.com/rizelabs), founded in 2024. The project has received backing from Alliance DAO and grants from the Solana Foundation and Circle. Encifher placed third in the DeFi track of an early hackathon competition. Specific founding team members have not been publicly disclosed in available sources.

Tokens

Encifher has no native governance or utility token. eTokens such as eZEC are privacy-wrapped representations of existing assets, not new issuances. Holders of eZEC retain full economic exposure to ZEC while gaining Encifher's confidentiality guarantees on Solana.

Solana Ecosystem Fit

Solana's public-by-default ledger exposes every transaction detail to any node operator or chain analytics firm. This structural transparency creates friction for institutional participants, privacy-conscious users, and use cases such as competitive on-chain trading, private OTC settlement, and payroll where revealing positions is costly.

Encifher addresses this by positioning FHE as composable middleware rather than a standalone privacy chain. Users and protocols stay on Solana and keep full access to its speed, liquidity, and tooling including Jupiter's DEX routing while gaining confidentiality at the token and transaction level. The eZEC launch demonstrates the model: rather than competing with established bridges, Encifher layers privacy on top of existing wrapped assets, expanding the privacy surface of Solana DeFi without requiring new infrastructure deployments.
