Ou seja, precisamos que haja uma mecânica similar ao Nifty Gateway, que utiliza um depositório dos NFTs, dispensando a necessidade de conexão de crypt wallet. O objetivo é democratizar...

    I recently had a Metamask trading bot coded that has been found to be malicious. The bot would accept deposits, function properly, but not withdraw. I've already lost quite a bit to this scam. This story only gets worse so I'll keep those details to myself but if you're interested, I will share. This project has a very short timeframe because just because we were scammed doesn't mean creditors understand the situation. My family and I need someone to be our white knight or white hat hero - whatever you want to call it.
