Contract Powers Registry / polygon
USDT (Polygon)
0xc2132d05d31c914a87c6611c10748aeb04b58e8f on polygon
In one line: upgradeable proxy (etherscan-declared); retained powers: burn_others, mint, ownership, upgrade.
Can this code be replaced?
Yes — this is a proxy. The address you interact with holds no logic of its own; it forwards calls to a second contract. Whoever holds the upgrade right can point it somewhere else, and every behaviour described on this page changes with it.

Who holds the keys?
no owner()/getOwner()/admin() responded — access control may use roles (AccessControl) or be renounced Access control may use role-based permissions (OpenZeppelin AccessControl), or it may have been renounced. This registry does not enumerate role holders.
What the privileged role can still do
Each card is a capability found in the code. declared = the contract’s published interface exposes it. bytecode-heuristic = the 4-byte selector appears in the compiled code, which often means the contract implements it — but it can equally be a function this contract calls on another contract. Only a verified source settles that.
Balances can be destroyed

Is there a bug bounty on this?
No live bug-bounty program matched this contract’s name in my index (186 Immunefi + 52 Cantina programs, rebuilt daily). Matching is by name, not by address — a program can cover this contract without the names lining up. Browse the full index at Bounty Radar.

How this was produced, and what it cannot tell you
Storage slots, bytecode and eth_call results were read from public RPC nodes;
where the source is verified, the published interface was read too. Nothing here is copied from another
site’s opinion. Generated in 890 ms on 2026-08-29.
- confidence="declared" means the ABI exposes the function. confidence="bytecode-heuristic" means the 4-byte selector appears in the code — usually its own dispatch table, but it can also be a selector this contract CALLS on another contract. Only a verified ABI settles it.
- admin.ownerType="contract" does not mean multisig — this endpoint does not inspect the owner contract.
- bounty.match="name-heuristic" matches a contract NAME to a program name; it is not proof the address is in scope.
What would change the answer: an upgrade after the date above; a power reachable only through a contract this one trusts; or role-based access control, whose holders this registry does not enumerate. Re-read the chain before you rely on it.
