Summary

A hook for the Saturn Omnichain project that records the initial pool tick from a liquidity bootstrapper contract in afterInitialize. All swap-related callbacks are no-op stubs; the hook does not alter swap behavior.

Hook Review: `hooks/bnb/0x75c19fdd847803c68ffe3b7df216b531b0a45000.json`

Address Flags ✅

Address suffix 0x5000 → binary 0101 0000 0000 0000. Lowest 14 bits: bit 12 (afterInitialize) = 1, all others = 0. This matches the flags section exactly, and is consistent with getHookPermissions() in the source.

Metadata ✅ (except description)

verifiedSource: true — confirmed by source_meta.json
chainId: 56 — matches BNB in chains.json
name: "SaturnOmnichainV4Hook" — matches contractName in source_meta.json and the contract definition
proxy: false — confirmed by source_meta.json and source (no proxy pattern, all state fields are immutable or plain storage)

Properties ✅

dynamicFee: false — no dynamic fee logic anywhere in the contract
upgradeable: false — all key addresses are immutable; no proxy, no delegatecall to mutable targets
requiresCustomSwapData: false — no beforeSwap/afterSwap flags; hook data is never inspected
vanillaSwap: true — correct per the rules: no swap flags at all
swapAccess: "none" — correct; no beforeSwap flag

Description ❌ — Factual Error

The description states:

"records the initial pool tick from a liquidity bootstrapper contract in afterInitialize"

This is incorrect. Looking at the source:

afterInitialize (line 134) is declared external pure and simply returns IHooks.afterInitialize.selector — it is a complete no-op.
The actual tick recording (initialTick = tick; poolInitialized = true;) happens in initializePools() (lines 85–89), which is an unrelated public external function, not a hook callback.

The description should be corrected to accurately reflect that afterInitialize is a no-op stub, and that the bootstrapper tick recording is performed by a separate initializePools() function. For example:

"A hook for the Saturn Omnichain project with only the afterInitialize permission bit set, but the afterInitialize callback is a no-op stub. Initial pool tick data is recorded by a separate initializePools() function that calls an external LiquidityBootstrapper contract. All hook callbacks are no-op stubs; the hook does not alter swap behavior."
