+# CrossGuardHook Pitch
+
+## Overview
+CrossGuardHook is a sophisticated Uniswap v4 hook that extends `BaseHook`, integrates EigenLayer’s Actively Validated Services (AVS) for staking-backed validation and slashing hooks, and layers in privacy-focused order execution plus simplified cross-chain swap functionality.
+
+## Problem
+- Public swap intent leaks MEV and invites front-running.
+- Execution needs to be conditioned on stake-backed operator validation with accountability (slashing).
+- Cross-chain handoff should happen through a clean adapter to contain bridge risk.
+
+## Solution
+Lock swap intent behind commit–reveal, gate execution on EigenLayer AVS operator validation (with slashing pathways), and isolate cross-chain delivery behind an explicit bridge interface so the hook stays minimal, auditable, and chain-agnostic.
+
+## Technical Components & Integration
+- Core contracts
+  - `DarkPoolHook` (`BaseHook`): commit/reveal swaps (`commitSwap`, `revealAndSwap`), enforces `commitPeriod` bounds and pool allowlists, and inspects `hookData` in `beforeSwap`/`afterSwap`. Derives batch hashes for AVS tasks and triggers cross-chain signaling via `CrossChainSwapInitiated`; bridge target settable via `setCrossChainBridge`.
+  - `DarkPoolTaskManager`: creates validation tasks (`createNewTask`), records operator responses, enforces quorum, and calls `SERVICE_MANAGER.recordTaskValidation`. Responses are gated by `SERVICE_MANAGER.isValidOperator`; pausable with force-complete controls.
+  - `DarkPoolServiceManager`: extends EigenLayer `ServiceManagerBase`, wiring AVS directory, registry/stake, allocation, permission, and rewards coordinators. Exposes operator stake checks, records validations, and provides hooks for slashing/reward flows.
+- EigenLayer touchpoints
+  - Operator validity via `RegistryCoordinator` + `StakeRegistry` stake/quorum data.
+  - AVS registration, permissions, allocations, and rewards routed through EigenLayer middleware; slashing hook available via the base service manager stack.
+- Cross-chain
+  - `_handleCrossChainSwap` decodes target chain/recipient/amount from `hookData`, computes a `swapHash`, and emits `CrossChainSwapInitiated`; bridging is abstracted behind `ICrossChainBridge`.
+
+## Why It Matters
+- Mitigates MEV by hiding swap intent until reveal.
+- Adds stake- and slash-backed operator validation before accepting batch results.
+- Keeps bridge risk contained with an adapter boundary and minimal hook surface.
+
+## Core Features
+- Commit–reveal with nonce-bound commits, deadline checks, and bounded block-based `commitPeriod`.
+- Pool gating via `setPoolEnabled`; owner control of commit period and bridge target.
+- Hook permissions limited to `beforeSwap`/`afterSwap`; commits marked executed after hook run.
+- Cross-chain hook path emits `CrossChainSwapInitiated` from encoded `hookData`.
+- Task lifecycle: `createNewTask`, operator `respondToTask` with quorum counting, force-complete admin path, pause/unpause.
+- EigenLayer operator gating through `isValidOperator` stake checks; validations recorded; reward/slashing hooks exposed via `ServiceManagerBase`.
