    I hired some devs to develop crowdfunding platform for me where business opportunities will be put in there to raise capital. The main difference compared to other crowdfunding websites is that the opportunities there, will be the ones that the platform´s team previously analyzed and will run the businesses after the raises are made. All other platforms just act as intermediary charging a fee on the amount raised. I want to create the platform’s token which the investors will receive back when they invest in the opportunities in the site. All the raises will be made in USDT and BUSD. Based on that, when Investors invest in a specific opportunity and receive the token back, they will be positively affected not by just the opportunity they directly invested, but all the business...

    Creating a crypto trading bot 4 days left

    I’m looking for someone to help create a crypto liquidity bot that detects new liquidity pairs created on uniswap and sushiswap. Pretty much a sniper bot. Would be nice to be able to have it arbitrage with other exchanges as well. I am not well versed in smart contracts or how one would set parameters for the bot. I believe this would encompass python, node.js and much more. If anyone feels up to the challenge and make it someone easy to run let’s get it!!!! Would be nice to learn more about smart contracts as well and how to run them through mythril to check security. This is just a personal venture that I have been interested in. Ik there are ones you can buy and others that are created for private use.
