Ecosystem: Partners, Apps, and Integrations Building Private DeFi

Any EVM-compatible rollup can add confidential compute by integrating a coprocessor such as CoFHE. Encrypted operations are executed off-chain and verified on-chain, preserving L2 performance and composability.

CoFHE for encrypted compute and the fhERC-20 standard for encrypted balances and transfers. Both integrate seamlessly with existing rollups, wallets, and DeFi protocols.

Deploy on your preferred L2, import the CoFHE interface in Solidity, and use fhERC-20 for private balances. Keep settlement and data availability on the rollup while off-loading encrypted execution to the coprocessor.

FHE isn’t executed directly inside the EVM. Solidity emits encrypted-compute requests to a coprocessor running fheOS and threshold-decryption nodes that return verifiable encrypted results.

Represent balances as fhERC-20, perform loan-health and liquidation checks through CoFHE, and expose selective decrypted views to authorized participants.

Use CoFHE encrypted compute for private bids or intents and FHE Hooks for Uniswap v4 to hide sensitive parameters during execution.

The CoFHE SDK and fhERC-20 templates provide Solidity-first development and encrypted state handling without changing the existing wallet or toolchain.

Bridge assets into an L2, mint fhERC-20, then use the CoFHE SDK to request user-specific decrypted views while contract state remains encrypted on-chain.

CoFHE enables real-time confidential computation with decryption speeds reported to be up to 50 times faster than current competitor benchmarks in the FHE space.

This dramatic performance improvement makes Fhenix's FHE-based encryption practical for blockchain applications, supporting encrypted computations on smart contracts with low latency and minimal gas costs.

The architecture achieves these speed improvements by offloading heavy cryptographic operations off-chain through the CoFHE coprocessor, enabling efficient encrypted data processing while maintaining privacy guarantees and full EVM compatibility.

Fhenix is currently in its testnet phase, with the "Helium" public testnet launched in mid-2024 to allow developers to deploy smart contracts and experiment with confidential computation on-chain. This testnet phase enables developers to build and test privacy-preserving applications using Fhenix's FHE technology before mainnet deployment.

CoFHE, Fhenix's FHE Coprocessor, has gone live on Arbitrum marking the first practical implementation of FHE. More information can be found below.
