The key that can freeze your USDT
Freezes are not issued by Tether the company; they are issued by one multisig contract on TRON, by a handful of addresses, under a signature threshold anyone can read. Everything on this page comes from that contract — the signer set from a live call, everything else from our event ledger.

Any 2 of these 3 addresses can freeze
any USDT balance on TRON.

Every time the key changed hands
2 changes in everything we have indexed. That is a small number, and it should be read as one: it says the set has been stable, not that it cannot change tomorrow.
What else this key does
The same threshold that freezes balances also mints and burns USDT. Function names are computed from the four-byte selector with keccak-256 and matched against the contract's published ABI — not copied from a lookup table. Anything that doesn't match is shown as raw hex and left undecoded.

2 selector(s) didn't match the published ABI. We show the hex rather than guessing a function name.
Withdrawn signatures and failed executions
Two things the chain records that nothing else surfaces: a signer taking their signature back, and an execution that was attempted and reverted. Both are rare — 17 events in everything we have indexed — and both used to be invisible here, folded into “nobody executed it.”
