Block the inflow of
criminal funds
Virtual assets based on blockchain technology are often illegally.
Eyez automatically tracks virtual asset addresses where anomalies are detected and manages a blacklist. If the address’s risk score is high and classified as a threat, Eyez will conduct an in-depth analysis of the transaction.
It can block the inflow of criminal funds in advance and secure the trust of customers and institutions using our exchange.

Efficiency of tracking
virtual asset
in crimes
Various cybercrimes occur in connection with virtual assets.
Eyez collects and provides dangerous virtual asset information from various sources. It also provides information on exchanges through clustering, such as the hot wallet address of a virtual asset exchange.
So, It can improve investigative power on the Dark Web and other unrecognized areas. It can improve the efficiency of tracking and investigating virtual assets involved in crimes.

As requested by the KlayHub team, S2W conducted an audit to evaluate the security of KlayHub’s token contracts from Nov 8 to 12. During the audit, we have carefully analyzed the workflows of all contracts in the scope to understand how the contracts were designed. The audit covered token contracts of KlayHub including both FT and NFT for the Klaytn blockchain(i.e., KIP7.sol and KIP17.sol from github repositories). We ensure that this audit was conducted in professional and sophisticated ways with state of the art methods for code analysis (e.g., symbolic execution, fussing) to discover security vulnerabilities and expose possible semantic inconsistencies between the implementation and the design of smart contracts.
From the assessments, S2W has uncovered no security issue that may have correctness or security impacts but, there were two minor considerations for better gas usage and code safety which did not impose any immediate security impacts.
On the whole, the given smart contracts were well reasoned and engineered. Most of them have been already published as the libraries on the official github organization of Klaytn(ref. https://github.com/klaytn/klaytn-contracts) to help build blockchain applications on Klaytn. In addition, some implementations were derived from openzepplin contracts which is one of the most popular open-source libraries for secure smart contract development.
Note that the scope of this audit is not a major part of the KlayHub DeFi services. We suggest conducting audits for the rest of the system as well to lessen the security risks.
