AlphaEngine routes trades through a CoFHE processor and settles netted
flow on Uniswap v4 with EigenCompute operator attestations. We use
“CoFHE processor” as the generic abstraction throughout.
What is AlphaEngine?
- Private by default: Users encrypt intents client-side; ciphertexts are queued and settled without exposing amounts or directions on-chain.
- Batched & netted: Multiple trades roll into epochs, matched off-chain, and only the net swap touches the pool, reducing gas and MEV surface.
- Attested execution: Restaked EigenCompute operators decrypt (when permitted), simulate Universal Trade Intents (UTI), sign results, and the contracts verify quorum before settlement.
Contracts
Uniswap v4 hook + shielded vault store encrypted balances, queue intents, and settle batches.
CoFHE processor
Runs encrypted math, validates bounds, and reveals only what operators are permitted to see.
EigenCompute
Restaked operator set that decrypts (as allowed), simulates, nets orders, and signs settlements.
Why this design
- End-to-end privacy: No plaintext amounts in mempool; ciphertext handles only.
- Fair batching: Epoch-based matching reduces leakage and improves execution quality.
- Modular compute: Swap between CoFHE providers without changing contracts.
- Operator accountability: Signature quorum + challenge paths ensure correctness.
Key Flows
- Intent submission: Users encrypt
amount,tokenIn,tokenOut,minOut, anddeadlinevia the frontend SDK, then submit to the hook. - Batch processing: The hook groups intents into epochs, grants decrypt rights to the operator quorum, and exposes batch roots.
- UTI simulation & matching: Operators simulate Universal Trade Intents over candidate routes, net opposing flow, and produce a signed result bundle.
- Settlement: The hook verifies signatures, applies encrypted internal transfers, and executes only the net swap on-chain. Events carry ciphertext handles for updated balances.
