CiFHErTradeArena

CiFHErTradeArena is a privacy-preserving trading tournament that makes DeFi yield fully competitive and trustless. Traders submit encrypted strategies (arrays of DeFi actions like deposit, borrow, or swap) using Fhenix Fully Homomorphic Encryption (FHE).

An EigenLayer AVS decrypts and simulates these strategies off-chain, ranks them based on APY, and posts the encrypted results back on-chain. At the end of each epoch, only the top-performing strategies are decrypted and deployed with real funds — ensuring that performance, not privilege, decides who manages capital.

With Avail Nexus integrated into the operator layer, multi-chain execution becomes a simple “call, not a bridge.” That means CiFHErTradeArena can execute encrypted strategies across Base, Arbitrum, and beyond in a single atomic step.

The result:

LPs earn best-in-class yield from aggregated top strategies.

Traders are rewarded proportionally to deployed capital and performance.

EigenLayer operators enforce fairness, privacy, and trustless verification.

Smart Contracts: Built on Solidity, reusing and modifying our AlphaEngine architecture to support multi-node encrypted strategies.

Confidential Compute: Uses Fhenix CoFHE for encrypting strategy parameters and enabling computation over ciphertexts.

Verification Layer: EigenLayer AVS decrypts and simulates strategies off-chain, posting encrypted APYs back on-chain for trustless ranking.

Cross-Chain Execution: Avail Nexus SDK integrated with the AVS layer enables bridgeless deployment — the operator calls sdk.execute() to dispatch winning strategies across rollups.

Frontend: Built with Next.js + TypeScript, using Fhenix’s cofhe.js SDK for client-side encryption.

Infrastructure: Deployed on Base as the canonical intent layer; simulated results and deployment transactions orchestrated through AVS + Nexus.

Key hack: Achieving encrypted simulation and ranking on-chain via FHE handles + EigenLayer AVS while maintaining complete strategy privacy and cross-chain composability.
