Shido DEX just shipped V4 with a complete backend overhaul. The infrastructure upgrade targets three core metrics: load time reduction (approaching sub-second), latency optimization across API calls, and improved state synchronization for the trading engine.

Key technical win: instant finality on trades. This means your swap transactions confirm in a single block without waiting for additional confirmations - critical for high-frequency traders and arbitrage bots.

The backend refactor likely involves optimized RPC endpoints, improved caching layers, and possibly a move to more performant database indexing. For devs building on top, this means more reliable API responses and fewer timeout errors during volatile market conditions.

If you're trading on Shido or integrating DEX functionality, V4's performance bump should be immediately noticeable in execution speed.
