Cryptoasset Analytics Platform

GraphSense is a cryptoasset analytics platform emphasizing full data sovereignty, algorithmic transparency, and scalability. GraphSense is open-source and free. It provides a dashboard for interactive investigations and, more importantly, complete data control for automatizing cryptoasset analytics workflows.

Supported Assets

The GraphSense system design supports UTXO- (e.g., Bitcoin) and account-model (e.g., Ethereum, Tron) ledgers. Currently, adapters are available for major cryptocurrencies like Bitcoin, Bitcoin Cash, Litecoin, Zcash, Ethereum and Tron. Additional ledgers can be integrated by implementing a lightweight adapter component.
