BlockSec Research describes the freezing of USDT on Binance as an exchange-imposed restriction. In the presented summary, the reasons are tied to KYC, AML, or jurisdictional checks rather than an on-chain blocking by Tether.

The source offers a five-step appeals process and separately mentions timeframes for consideration. Specific steps and the duration of the process are not disclosed in the available description.

This is important for users trying to understand exactly where the restriction occurred: on the Binance platform or on the blockchain. The conclusion is based on a single BlockSec Research meta-description, not on independent confirmation or available full-text material.
