I Built Autonomous Agents That Trade on Solana Without Seeing Private Keys

I wanted to test out a theory where I have autonomous agents make trading decisions on Solana without handing them private keys. So I built something to simulate that. Think of a situation where you're building an agent that decides to buy 0.5 SOL worth of a certain token, and it needs to sign a real transaction on-chain. Ordinarily, there's really no way this would work without you giving the agent access to a private key. But the issue here is that the moment you give it access to a private key, you've.
