DrawBridge

The DrawBridge service offered by The Investigation Сompany serves as an analytical tool for blockchain bridges, aiding in the matching of transactions across various blockchains. This tool enhances the complexity of analytics and the tracing of cryptocurrency assets, even when popular methods of Bitcoin tokenization and other cryptocurrencies are employed to obscure their tracking.

Currently, the DrawBridge service has established a mechanism for matching transactions conducted using RenBTC, a blockchain bridge commonly utilized by cybercriminals to evade the tracking of illicit assets. This high degree of matching reliability is achieved through a specialized algorithm that takes into account factors like gas prices, Bitcoin network congestion, transaction volume, and transaction time. DrawBridge leverages machine learning mechanisms, including Random Forest and Reinforcement Learning, to accurately trace transactions with similar volumes conducted in close proximity.

At present, over 87% of Mint RenBTC transactions and approximately 91% of Burn RenBTC transactions are identified on the Ethereum and Binance Smart Chain blockchains in real-time. The DrawBridge service has also developed algorithms for matching transactions on the Ethereum and Binance Smart Chain blockchains, which are now utilized by the RenBTC project.

Furthermore, interaction with the developed DrawBridge algorithm through an API is currently available. Implementing the DrawBridge service facilitates real-time tracing and identification of criminal assets, enabling law enforcement agencies and VASP to take timely counteractions.
