Add SaturnOmnichainV4Hook hook on base

[hooklist-generator]

Summary

A minimal hook for the Saturn Omnichain project that implements only afterInitialize as a no-op. Pool setup is coordinated externally via initializePools(), which calls an ISaturnOmnichainLiquidityBootstrapper contract to bootstrap liquidity and records the initial tick and poolInitialized flag.

Review: hooks/base/0xa6c9f8ceed4b35daa104bd2eb7b8edc2174c5000.json

Address Flags

Decoding the lowest 14 bits of 0xa6c9f8ceed4b35daa104bd2eb7b8edc2174c5000:

• Last 4 hex digits: 5000 = 0101 0000 0000 0000 binary
• Lowest 14 bits: 01 0000 0000 0000
• Bit 12 = 1 → afterInitialize: true
• All other bits = 0 → all other flags false

This matches the flags section exactly. Confirmed by getHookPermissions() in source, which also sets only afterInitialize: true.

Source Code Verification

Contract: SaturnOmnichainV4Hook — verified on Base (chainId 8453). source_meta.json confirms verified: true, proxy: false.

The afterInitialize callback is a pure no-op — it simply returns IHooks.afterInitialize.selector without any state changes.

The initializePools() function (not a hook callback) calls LIQUIDITY_BOOTSTRAPPER.bootstrap(), records the returned tick in initialTick, and sets poolInitialized = true. This matches the description.

Properties

Property	Claimed	Verdict
dynamicFee	false	✓ — No updateDynamicLPFee() call; no swap callbacks active
upgradeable	false	✓ — All addresses are immutable; no proxy, no delegatecall, no SELFDESTRUCT
requiresCustomSwapData	false	✓ — No swap flags; hook does not participate in swaps
vanillaSwap	true	✓ — No swap flags at all; must be true per spec
swapAccess	"none"	✓ — No beforeSwap flag

Metadata

• name: "SaturnOmnichainV4Hook" — exact contract name from verified source ✓
• chainId: 8453 — matches Base in chains.json ✓
• verifiedSource: true — confirmed ✓
• description: Accurately describes the contract: minimal hook with a no-op afterInitialize, pool setup via initializePools() calling the bootstrapper, and recording of initialTick/poolInitialized. No marketing language, audit claims, or unsupported assertions ✓

All fields are correct. Approving.
