I'd let an agent prepare a transaction. I'd still want the final say. @Ledger introduced Agent Intent yesterday, and it's live in beta. According to Ledger, an agent can prepare proposals while you review and approve them on a compatible Ledger signer. Private keys are designed to stay on the device. What interests me is the split in responsibilities. Let the agent do the legwork, then give me a clear view of what I'm being asked to sign. The approval screen still has to make sense. A convincing explanation from an agent wouldn't be enough for me. Would you use this for routine wallet tasks?
