Upgradeable proxy — logic can change after launch
Worth knowing about, and common enough that it is not on its own a reason to conclude anything.

- What it means
- The contract is a proxy: the logic it runs can be swapped for different logic later.
- Why a contract might have it
- The standard way to ship a contract that can be patched. Most large, well-audited protocols are proxies, because an unfixable bug is worse than an upgradeable one.
- When it matters
- It means today’s audit describes today’s code. Whoever controls the upgrade key controls what the token does tomorrow.
2,486 of the 28,512 contracts we have read carry this — about 8.7% of the catalogue. Worth knowing about, and common enough that it is not on its own a reason to conclude anything.
