Components

AlphaEngine contracts

Uniswap v4 hook + shielded vault that stores encrypted balances, queues intents, and settles batches.

CoFHE processor

Performs encrypted math, validates constraints, and reveals only what operators are permitted to open.

EigenCompute Operators

Restaked operator set that decrypts (when allowed), simulates, nets orders, and signs settlement payloads.

Frontend + SDK

Encrypts user inputs, submits multiple trades in one session, and tracks batch lifecycle through settlement.

​
Data Flow

  1. Encrypt & submit — The frontend encrypts intents (amounts, bounds, route hints) using the published CoFHE key and submits to the hook.
  2. Queue & permission — The hook records ciphertext handles, associates epochs, and grants decrypt rights to the operator quorum.
  3. Batch & simulate — Operators pull the epoch buffer, request decrypt where allowed, run Universal Trade Intent simulations, and compute net flows.
  4. Attest & settle — Operators sign the batch result; the hook verifies quorum signatures, applies encrypted internal transfers, and executes the net swap on-chain.
  5. Return results — The hook emits events with ciphertext handles for updated balances; frontend decrypts locally where user permissions exist.

​
Multi-Trade Support

  • Session-scoped keys: A single encryption session can produce multiple intents that share metadata (epoch, gas prefs).
  • Batch netting: Opposing directions are netted to reduce gas and MEV surface; only the net delta hits the pool.
  • Fairness: Intents carry deadlines; expired intents are dropped before netting to avoid toxic flow.

​
Universal Trade Intent (UTI)

  • Simulation: Operators simulate routes off-chain (AMMs, bridges, lending) under FHE or after permitted decrypt.
  • Validation: Policy checks ensure slippage, asset allowlists, and gas bounds before settlement.
  • Outputs: A signed result bundle includes the net swap, internal transfers, and per-intent settlement handles.

​
On-Chain Contracts (Hook)

  • Encrypted balances: mapping(token => mapping(user => euint256)) with contract and sender permissions.
  • Intent buffer: Stores ciphertext handles plus deadlines and token pairs.
  • Batch settle: Applies encrypted internal transfers first, then executes public net swap via Uniswap v4.
  • Events: Emit batch IDs, Merkle roots, and per-intent settlement handles for frontend tracking.

​
Failure & Safety Rails

  • Timeouts: Batches carry TTL; if no quorum attests, intents can be reclaimed or rolled into the next batch.
  • Replay protection: Nonces and epochs prevent reusing ciphertexts across batches.
  • Fallback exits: Users can withdraw plaintext balances that were never consumed by a batch (vault exit path).
  • Operator accountability: Attestations are signed; misbehavior can be challenged and escalated to slashing.

​
Component deep dive

  • Hook & encrypted tokens: Store encrypted balances, queue intents, and settle batches while exposing strategy submission entry points.
  • Strategy manager & AVS: Maintain epoch state, permissions, and aggregated performance reports for EigenCompute operators.
  • Frontend: Encrypts intents, submits multi-trade sessions, and monitors Nexus-dispatched executions.
  • Docs & specs: Centralize UEI, AVS, and migration plans so coprocessor swaps stay consistent.
