    I'm building a model that requires me to have the original English contract with the converted paired Solidity Smart Contract. I'm going to need a lot of these pairs and they have to be accurate. I can't seem to find them anywhere. I found a good dataset on Github, but it didn't have the accompanying English original contracts, so I can't train the model on them. Is anyone good at tracking down datasets on the web, or somehow have access to thousands of these pairings of English contracts and Solidity Smart Contracts?
