1. Fix the block
Use the transaction block for historic execution research or a clearly dated head block for a current observation. Confirm that the provider supports the requested historic state.

How Proxy snapshot comparator works
The inspector validates three BNB Chain address shapes and compares them with the documented MONSTA proxy, implementation and administrator observed by Cake Monster Research at block 117,963,261. A match reproduces that snapshot only. It does not prove the same storage values exist at another block. Read the upgradeable-proxy risk guide to inspect the documented rule and its evidence boundary in more detail.
Proxy snapshot comparator equation
snapshot match = proxy match ∧ implementation match ∧ administrator match ∧ observation block matchProxy snapshot comparator example
Entering the documented proxy, implementation, administrator and block 117,963,261 returns a complete snapshot match. Changing one implementation character produces a mismatch while preserving the other independent results. Open the MONSTA contract audit method before treating the modeled output as present contract behavior.

COMPARE STATE.
DO NOT SUBSTITUTE MEMORY.
The inspector is deliberately a comparator rather than a live RPC widget. Readers provide values from their own node or explorer workflow, making the source, block and mismatches explicit.
Recorded implementation
0x68f9ce4817f7edb62f8981c6d399a687f930922cThis address was observed behind the documented proxy at block 117,963,261. A different value may indicate another block, a collection error or an upgrade. The comparator does not decide which explanation applies.
Recorded administrator
0x5e92adf8145342c18f373e70dc75fe6e7d75b235The administrator is a control address, not a named human or organization. Matching it reproduces an on-chain storage observation without establishing who controls its keys.
Four fields form one claim
“MONSTA used implementation X” is incomplete without the proxy and observation block. “Administrator Y controls it” is also incomplete without the storage slot and block. The complete research unit joins proxy, implementation, administrator and block so each statement can be independently repeated.
The all-match result is intentionally strict. A reader comparing correct current state with the older reference block should expect the block result to differ. That does not automatically mean an upgrade occurred; it means the two records are not the same dated snapshot.
BUILD AN EIP-1967
EVIDENCE PACKET.
A proxy finding should preserve raw storage evidence as well as decoded addresses.
2. Read standardized slots
Query the EIP-1967 implementation and administrator storage positions. Save raw 32-byte responses before extracting the final 20-byte address.
3. Verify executable code
Check deployed bytecode at the implementation. Explorer source verification helps interpretation but should not replace the bytecode identity check.
4. Review changes
Search upgrade events and administrative transactions around the period being studied. Storage observations show state; transactions can explain how it changed.
Only proxy matches
Identity without stateThe stable entry point is correct, but implementation and control claims are unresolved.
Addresses match, block differs
Separate observationThe values may be unchanged, but the result is not the same dated snapshot.
All four match
Snapshot reproducedThe comparison passes; code behavior and safety still need analysis.
Continue with control analysis
Study proxy upgrade risk first, then use the audit methodology to distinguish a historic review from current executable state.
MONSTA PROXY INSPECTOR FAQ.
Answers about proxy snapshot comparator, its inputs and the evidence limits specific to this result.
01Does the inspector read live contract storage?
No. It compares values you collected independently with a dated Cake Monster Research snapshot. That makes the check reproducible and prevents an unavailable RPC service from being mistaken for verified state.
02Where do implementation and administrator values come from?
Transparent proxies normally store them in standardized EIP-1967 slots. Read those slots from a trusted archive-capable BNB Chain node at the block you intend to study.
03Why must I enter an observation block?
A proxy can be upgraded. The block binds each implementation and administrator observation to one chain state instead of presenting it as timeless.
04Does a complete match prove the contract is safe?
No. It reproduces recorded identity and control values. Source verification, bytecode, permissions, liquidity and the intended call still require analysis.
05Can I compare an older transaction?
Yes, but obtain the EIP-1967 values at that transaction's block. A current explorer display cannot prove which implementation executed a historic call.
