We integrated Uniswap v4 by building HookVault as a native hook and shielded vault. Fhenix CoFHE provides encrypted types and secure unsealing for swap intents. EigenLayer AVS powers the operator committee for decryption, simulation, and batch validation, ensuring slashable correctness. Together these partners enable end-to-end private, verifiable swaps.

Current DeFi yields are capped by the knowledge of a few fund managers, while on-chain traders expose strategies and suffer MEV. We built AlphaEngine Hook to solve both: giving traders privacy through FHE + hooks, and creating Veda Vaults where strategies compete openly. This makes asset management permissionless, market-driven, and automated — like a decentralized WorldQuant for crypto.
AlphaEngine combines FHE privacy, Uniswap v4 hooks, and EigenLayer AVS to create a new asset management paradigm. AVS operators simulate and validate strategies, enforcing profitability constraints before execution. This ensures only high-alpha trades go through, improving LP yields, democratizing access to top-tier strategies, and turning DeFi into a self-sustaining quant ecosystem.
We had to integrate multiple bleeding-edge primitives: FHE in Solidity for encrypted balances, Uniswap v4 hooks for routing, and AVS for slashable off-chain profit checks. Designing the Veda Vault flow — where trades must pass profitability thresholds before execution — required careful balancing of privacy, efficiency, and validation costs. Building all this into a seamless, automated system was a huge technical challenge.
