Add SaturnOmnichainV4Hook hook on ethereum

[hooklist-generator]

Summary

A minimal hook that only uses afterInitialize (as a no-op stub) to satisfy the interface. Provides an initializePool() helper that deploys an ETH/token pool with fixed parameters (0.3% fee, tick spacing 60). Does not alter swap or liquidity behavior.

Review: hooks/ethereum/0x11112e31f78c7f7c9fea7c0e1ca2f8e16505d000.json

Address Flag Verification

Address 0x11112e31f78c7f7c9fea7c0e1ca2f8e16505d000 — lowest 14 bits:
0xd000 & 0x3FFF = 0x1000 = 0b01_0000_0000_0000

Only bit 12 (afterInitialize) is set. This matches the flags section exactly, and is confirmed by getHookPermissions() in the verified source.

Source Code Analysis

The contract is a minimal IHooks implementation:

• afterInitialize is the only enabled permission; its implementation is a no-op stub (returns the selector).
• initializePool() deploys an ETH/token pool via POOL_MANAGER.initialize() with hardcoded POOL_FEE = 3000 (0.3%) and POOL_TICK_SPACING = 60. Records initialTick and sets poolInitialized = true.
• All other hook callbacks are implemented but not enabled in getHookPermissions().
• No swap or liquidity behavior is altered.

Properties

Property	Filed	Verdict
dynamicFee	false	Correct — no updateDynamicLPFee(), no fee override in beforeSwap
upgradeable	false	Correct — POOL_MANAGER and TOKEN are immutable; no proxy, no mutable delegatecall; source_meta.json confirms proxy: false
requiresCustomSwapData	false	Correct — no swap hooks
vanillaSwap	true	Correct — no swap flags at all
swapAccess	"none"	Correct — no swap flags

Metadata

• verifiedSource: true — confirmed by source_meta.json ("verified": true)
• chainId: 1 — matches Ethereum in chains.json
• name: "SaturnOmnichainV4Hook" — matches contractName in source_meta.json
• description — accurate and technically substantiated: the afterInitialize no-op stub, initializePool() helper with 0.3%/tick-60 fixed parameters, and no swap/liquidity impact are all verifiable from source. No marketing, audit, or safety language present.

All fields are correct. Approving.
