AI agents paying each other — where do the keys actually live?

Been thinking about this since the DePIN thread. Everyone talks about AI agents paying each other soon, like one agent hiring another one and settling it on-chain by itself.

Cool idea, but where do the keys live then? If the agent is running on some server somewhere and it can sign by itself, that is not really self-custody anymore, is it. You gave the keys to a box you do not control.

Do you just accept that and keep tiny amounts in there, like a hot wallet you expect to lose? Or is there a setup people actually use, like the agent can only spend up to a limit, or it has to ask a human to sign anything big?

Genuinely curious how people who run nodes or agents are doing this in practice right now, not in theory. What is your setup?
