Most DeFi security discussions start after something goes wrong. A hack happens, wallets are drained, dashboards light up, and everyone analyzes what could have been prevented. That made me wonder: why isn't there a standard way to decide whether a transaction should be allowed *before* it reaches the blockchain?

This is the problem @NewtonProtocol is tackling. Instead of simply monitoring activity, Newton evaluates a transaction against predefined policies before settlement and returns an onchain signed pass/fail attestation. It's a subtle architectural shift, but one that could make a significant difference for institutions, DAO treasuries, or AI agents managing capital.

Imagine a treasury policy that blocks interactions with sanctioned addresses or prevents excessive leverage before assets ever move. That's closer to how traditional payment authorization works, but adapted for open finance.

I think this "authorization layer" is one of those infrastructure pieces that most users won't notice directly, yet many applications may eventually depend on it. As DeFi becomes more sophisticated, prevention could prove more valuable than post-event monitoring.

What kind of policy would you want every onchain transaction to pass before execution?
