The Fimio Malicious Smart Contract API (alpha 0.0.1) is trained on Ethereum smart contracts, and is specifically trained to identify phishing and honeypot behavior.
The training dataset for the alpha 0.0.1 model goes back to Ethereum genesis (August 2015); however the performance of the model has been optimized for contracts that were minted from January 2022 onwards (in other words, the model has much stronger confidence in scores for contracts created after January 2022).
