An upgradeable proxy is a smart contract pattern that lets code be changed after deployment. A fixed proxy address holds the data, while a separate logic contract can be swapped for a new version.
Reentrancy is a smart contract vulnerability where an external call lets another contract call back in before the first call finishes. Attackers use it to act on stale state, often withdrawing funds repeatedly.
A security audit is a structured review of systems, code, configuration or processes against a defined standard. It produces findings showing where security falls short and how to fix it.
A multisig is a crypto wallet that needs approval from several keys before a transaction can go through, such as any three of five signers. It removes the single point of failure of one private key.
