Bybit Security Lab Reveals 16 Hidden Fund Freezing Functions on Mainstream Blockchains

A report released by Lazarus Security Lab, a subsidiary of Bybit, states that 16 mainstream blockchains already include mechanisms in their code to freeze or restrict user funds, and another 19 blockchains can achieve similar functionality through minor protocol modifications. The report identifies three types of freezing mechanisms: hard-coded freezing (such as BNBChain and VeChain), configuration-based freezing (such as Sui and Aptos), and contract-based freezing (such as HECO).
