Most payments on the blockchain are confirmed by people themselves.

Lately, AI agents have increasingly been helping people run errands.

The next question is: how do they pay, and how do they interact with different apps?

In early September, Sui introduced an approach called “Payment Intent.”

The official description says that a request, whether it comes from an AI agent or a regular application, can trigger actions in multiple apps at once.

And everything is settled in a single atomic transaction.

An “atomic transaction” can be thought of as “all or nothing.”

Here’s an on-chain example: AI first swaps tokens, then deposits the assets it received into a lending pool.

Put these two actions into a single atomic transaction, and if either step fails, the entire transaction won’t go through.

This guarantee applies to actions within the same on-chain transaction.

It doesn’t automatically roll back off-chain services.

This “nothing gets done halfway” property is especially useful for automated actors like AI agents.

This also ties in with the theme of Sui Basecamp, taking place October 7–8.

At the end of August, the organizers said this year’s event would focus on the “agent economy,” including instant settlement, autonomous payments, private transactions, stable digital dollars, and post-quantum security.

Next time you hear “AI agent payments,” consider how they’re guaranteed not to leave things half-done.
