Our contracts receive funds from users, issue vault IOU tokens, stake funds and then bond them when optimal (again, most of this is a fork of ). You can see the strategy contract posted here: and our vault contract posted here: We're interested to hear what you think an estimated timeline/price would be for this audit (especially since it's a fork of beefy already).

    I can build you a blazingly fast token sniper bot for the Pancakeswap decentralized exchange on the Binance Smart Chain. It works by scanning the mempool / txpool for liquidity add transactions for your specified token. It is able to catch these transactions before they are confirmed on the blockchain (whilst they are still pending) meaning you'll be one of the first people to be able to buy any newly listed token. For top speeds (0 second snipes) this will require a subscription to a mempool transaction provider however they offer a free version which still achieves very fast snipes. I only provide the software itself and the instructions on how to get it up and running. With enough research into upcoming tokens this has the ability to pay itself back very quickly depending on how m...
