Built a custom async Solana trading engine on a Free RPC. Will this survive mainnet?

Post original

Hey everyone, I’ve been building an algorithmic trading engine for Solana in Python. To keep costs at $0, it runs purely on a Free Tier RPC using heavily optimized asyncio pipelines to prevent rate-limiting. Instead of static rules, it uses a self-learning risk manager that dynamically adjusts Take-Profit and Stop-Loss based on live market volatility. The simulation results (screenshot attached) look solid, keeping losses tight while letting winners run. But I know live mainnet is a completely different beast. My question: Will a highly optimized Free RPC setup survive the MEV bots and network congestion, or is a paid/colocated node 100% mandatory to not get wrecked? Appreciate any advice!   submitted by   /u/MayurBundela [link]   [comments]
