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]

Free RPC endpoints are rate-limited and lack the consistency needed for latency-sensitive trading, especially once MEV bots and congestion kick in during volatile periods. Even heavily optimized asyncio will hit walls when block times fluctuate or when competing against colocated validators. A self-learning risk manager sounds promising in sims, but without deterministic execution paths and private mempool access, slippage and missed fills become the real P&L killers rather than just TP/SL logic. Most production Solana bots I’ve seen move to paid or self-hosted nodes once they cross even modest volume thresholds. The difference isn’t just speed; it’s predictability under load and the ability to implement custom retry or priority-fee heuristics that free tiers simply block. Test against historical congestion windows first before assuming the free tier will hold.
Your setup is a common starting point, but the free RPC constraint will almost certainly bite once real capital and competition are involved. If you’re already seeing solid sim results, the next step is usually a paid endpoint or light validator co-location to control latency variance. Happy to review your retry and fee logic if you want a second set of eyes on where it might break.
