We provide insights via tailored solutions and automated data provision

Crypto Sustainability API

Our Crypto Sustainability API provides real-time sustainability metrics over a wide range of cryptocurrencies as well as relevant ERC-20 tokens on Ethereum, NFT collections, Layer 2 solutions. Through our API, we provide direct access to our database and enable to assess the climate impact of individual holdings and transactions.

Chain analytics

If your project is not yet part of our data set, we may support you in measuring/auditing your energy efficiency and carbon footprint. Feel free to reach out to us directly. We are capable to set up measure on virtual machines and in physical setups in our lab as we are convinced that direct node access increases data precision.

MiCA-readiness assessment

If you are a token issuers and crypto-asset service providers, you will be required to disclose adverse climate and environment-related impacts under the Markets in Crypto-Asset (MiCA) regulation. We can help you understand if you are impacted by MiCA, assess your "MiCA readiness level" and support you in meeting the upcoming requirements.
