Need complete, ready-to-run source code for two solutions: • an MEV/Sandwich bot built for back-running transactions, and also provide separate prediction bot as a feature(optional) The chain does not matter—Ethereum, BSC, Polygon or any other EVM network are all acceptable as long as deployment can be switched through simple configuration. Please include a working demo link or short screen capture that proves both bots operate in real market conditions, plus a brief explanation of setup steps. I will decide on charges after I review the demonstration and your previous similar projects, so attach links or repos that showcase past work on arbitrage or MEV strategies. Delivery will consist of the full codebase, installation guide, and any configuration files needed to start trading immediately.
