Bybit Research Finds Dozens of Blockchains Capable of Freezing Funds

Bybit’s Lazarus Security Lab reports that 16 blockchains can freeze assets directly, while 19 more could enable this through minor protocol changes, posing implications for asset control and governance.

Fact Check
The core technical assertion of the statement—that numerous blockchains possess the technical capability to freeze user funds—is overwhelmingly supported by the provided sources. Multiple independent sources confirm the existence and common use of "pausable" functions within smart contracts and tokens, which is a direct mechanism for freezing assets or activity.Evidence for this technical capability is robust and varied:- An X post from the smart contract auditing firm QuillAudits implicitly confirms that pausable functions are a known security mechanism, treating the lack of one as a failure.- A post from a Binance research analyst provides a concrete, real-world example of pausable pools being actively used for recovery, demonstrating the feature in practice.- A blog post referencing the OpenZeppelin library, a widely used industry standard for smart contract development, shows that a "Pausable mechanism" is a common and easily accessible feature for developers. The prevalence of this library across dozens of EVM-compatible blockchains makes the claim that this capability exists on "dozens of blockchains" highly credible.- Additional sources from a smart contract development company and a crypto exchange blog further corroborate that pausable functions are a recognized feature.The only unverified part of the statement is the specific attribution to a "report from Bybit Research." None of the provided sources mention or link to such a report. However, the absence of this specific evidence does not invalidate the central technical claim, which is independently and strongly substantiated. Therefore, the statement is assessed as 'likely_true' with high confidence because its most critical component is well-evidenced.
Summary

A new report from Bybit’s Lazarus Security Lab reveals that 16 major blockchains have built-in fund freezing capabilities, and 19 others could introduce such measures with minimal protocol adjustments. These mechanisms range from hardcoded functions to configurable network parameters and smart contract-based controls. Historical cases cited include the Sui network and BNB Chain freezing hundreds of millions in stolen crypto assets.

Terms & Concepts
  • Smart contract: Self-executing blockchain code that runs when predetermined conditions are met.
  • Protocol tweak: A change or update to a blockchain’s rules or parameters that can alter functionality, such as enabling fund freezing.
  • Fund freezing: The ability to restrict the movement of digital assets on a blockchain, typically used to prevent theft or enforce compliance.
