I’ve been thinking about how AI agents will make payments

A lot of people say agents need stablecoins. Wallets are easier to spin up than bank accounts; stablecoins are more programmable, composable, etc.

At the same time, Stripe is powering agents on existing rails (like with Perplexity), and companies like Nekuda are building SDKs on top of card networks.

I'm trying to develop a clearer POV on which setup actually works better today - what's the best writing or thinking on this?
