Upgradeable proxy contract
A contract whose code can be swapped. It may be fair today and behave differently after an upgrade.
Why it matters
A code review shows what the contract does now. If it can be upgraded, that review guarantees nothing for tomorrow: the owner could deploy a new version with a 99% tax or a sell ban.
What it looks like in practice
Proxies are normal for large projects and tokenized assets, where upgrades are controlled by a multisig with a delay (timelock). For a memecoin with a single wallet owner it is a reason to be careful.
How QUVR Pulse checks it
QUVR Pulse detects standard proxies (EIP-1967, beacon, minimal proxies), shows the implementation and admin addresses and checks whether the admin is a wallet, a contract, a multisig or a timelock.
FAQ
Does renouncing ownership solve the proxy problem?
Not always: a proxy often has a separate upgrade admin. You need to check who can upgrade the implementation, not only who owns the token.
