Built a Solana DEX prototype with some clever client-side signing optimization and custom RPC infrastructure—managed to get buy execution down to 400ms flat. The orderbook streaming is running smooth.

Anyone with a solid idea and the right tools can move fast. That changes everything for how crypto scales from here.
