EigenDex

EigenDEX is a private, verifiable perps DEX using EigenCloud enclaves for confidential, provably fair trading.

🧠 Inspiration

Most perpetuals exchanges today are either centralized and opaque or fully public on-chain. Traders have to choose between privacy and trust. EigenDEX aims to bridge that gap — a private but verifiable perps DEX where all execution is confidential, yet every trade is cryptographically proven correct.

⚙️ What It Does

EigenDEX runs its matching engine inside attested Intel TDX enclaves on EigenCloud. Each trade, liquidation, and funding update is computed privately within the TEE and produces a cryptographic attestation proving correctness. These attestations are anchored to Ethereum through the EigenVerify contract, while EigenLayer restaking ensures liveness and slashing-based accountability.

🏗️ How We Built It

  • Deployed the trading engine as an EigenCompute app inside Intel TDX enclaves.
  • Built the on-chain verifier using Hardhat + Solidity to authenticate attestation signatures.
  • Connected the enclave backend to a Next.js + Tailwind + ethers.js front-end with live proof logs.
  • Simulated EigenLayer AVS restaking logic to demonstrate operator rewards and slashing events.

🚧 Challenges We Ran Into

  • Debugging cross-layer attestation verification between the enclave and Ethereum.
  • Handling EventEmitter leaks from repeated provider connections during dev.
  • Designing a UI that communicates both privacy and verifiability intuitively.

🏆 Accomplishments We're Proud Of

  • Built the first working prototype of a TEE-anchored perps DEX secured by EigenLayer.
  • Completed an end-to-end attestation-to-Ethereum proof pipeline.
  • Designed a polished DEX UI with live system health, state-root logs, and verified batch updates.

📚 What We Learned

  • How to deploy and manage verifiable apps on EigenCloud’s attested runtime.
  • How restaking economics enforce correctness beyond hardware trust.
  • That privacy and transparency can coexist through attestations and cryptographic proofs.

🚀 What's Next for EigenDEX

  • Integrate ZK-proofs for zero-knowledge trade verification.
  • Expand to multi-enclave networks for distributed order routing and uptime.
  • Launch attested liquidity pools and cross-exchange settlement using EigenLayer operators.
  • Open-source the attestation verification framework for other verifiable DEX builders.
