0x8a5d…18b2f
Compare an address with the documented legacy MONSTA proxy before inspecting its implementation, administrator and transaction history.

Runs in this browser. No wallet, account, signature or transaction.
The documented legacy MONSTA proxy is 0x8a5d7fcd4c90421d21d30fcc4435948ac3618b2f. The checker validates the BNB Chain address format, normalizes letter case and compares every character. A match proves address identity only; it does not prove that an interface, implementation or transaction is safe. Open the complete MONSTA address registry to inspect the documented rule and its evidence boundary in more detail.
valid format = 0x + 40 hexadecimal characters; identity match = normalized input equals the documented proxy addressPasting the complete documented proxy returns a match. A look-alike address with even one different character returns no match, regardless of its token name, ticker or logo. Understand upgradeable-proxy risk before treating the modeled output as present contract behavior.
The 0x prefix and every hexadecimal character must be present.
Letter case does not change the underlying BNB Chain address.
A match does not validate delegated code, administrator power or a transaction.
The MONSTA contract address checker answers one binary question: does the complete input equal the documented legacy proxy? It intentionally refuses to infer identity from branding, a ticker, a shortened string or checksum styling.
0x8a5d7fcd4c90421d21d30fcc4435948ac3618b2fCopy this value from a trusted first-party record or established explorer page, then compare it with the destination shown by the wallet. Do not type it from memory and do not approve a transaction merely because the first and last characters look familiar.
Is the input 0x followed by 40 hexadecimal characters?
Local validation in this browser.
Only that the string has the shape of an EVM address.
Does every normalized character equal the documented MONSTA proxy?
Full-address comparison against the recorded reference.
That the address is the same proxy, not that its behavior is safe.
Which contract currently receives delegated calls?
EIP-1967 implementation slot, verified source code and bytecode.
Which executable logic sits behind the proxy at the observation block.
Who can upgrade or administer the system?
Admin slot, ownership roles and upgrade transaction history.
The observable control surface, not the identity or intent of its operators.
What will the requested method and parameters do?
Decoded calldata, simulation, allowances, recipient and value.
The specific transaction effect under the observed state.
The stable proxy is the public identity users encounter, but it can delegate execution to a separate implementation contract. An authorized upgrade can change that implementation without changing the proxy address checked above. That is why “the address matches” and “the code is unchanged” are different claims.
Researchers should preserve an observation block whenever they record the implementation or administrator. A current storage-slot value cannot by itself prove which code handled an older transaction.
Stop at the first failed layer. Later checks cannot rescue an incorrect destination address.
Paste the destination into this checker and confirm a match. Re-copy from the source if even one character differs; never edit a near match manually.
Read the proxy’s EIP-1967 implementation slot at a declared block. Compare deployed bytecode and verified source instead of relying only on an explorer label.
Identify the admin or upgrade authority and review relevant changes. Privileged control is a risk dimension even when the current implementation appears familiar.
Check the method, token amount, allowance, spender, recipient and native BNB value. A legitimate contract address can still receive an unintended or malicious call.
Use a reputable simulation where available. Reject unexplained unlimited approvals, unexpected delegate calls or outputs that differ from the interface description.
Identity passes. Implementation, control and transaction intent remain unresolved.
The destination is another address even if the token name and logo appear identical.
A matching prefix and suffix can conceal different characters in the middle.
The address registry records the relevant Cake Monster contracts. The proxy-risk guide explains how implementation and administrator changes alter what a stable address can do.
Answers about contract matcher, its inputs and the evidence limits specific to this result.
No. The checker compares a correctly shaped hexadecimal address without treating letter case as identity. An explorer may display checksum capitalization as an additional typo check.
No. It identifies the documented proxy. Safety still depends on implementation code, administrator power, permissions, liquidity and the exact transaction.
A shortened address can hide a different middle. Comparing the complete value avoids relying on a matching prefix and suffix alone.
An upgradeable proxy delegates calls to a separate implementation. An authorized upgrade can replace that implementation without changing the stable proxy address.
Verify the proxy and implementation, identify administrator power, decode the method and parameters, review the spender and allowance and simulate the request where a reputable tool is available.
