The Problem

The agentic commerce gap — AI agents are trusted with real commercial tasks but the payment layer was built for humans.

Three Structural Problems

By 2026, AI agents handle real commercial tasks across millions of users. Yet the payment layer was designed for humans. Three structural problems block safe agent commerce.

1. No Bounded Delegation

Giving an agent full wallet access is equivalent to giving a contractor your bank card PIN. Existing approaches force a binary choice: full custody (dangerous) or human approval for every transaction (useless for autonomous workflows). There is no standard mechanism to say "agent A may spend up to 50 USDC/day at approved merchant categories" and have that constraint enforced at the cryptographic and contract level.

2. No Machine-Readable Authorization Chain

When an agent initiates a payment today, there is no standardized evidence trail proving: (a) the user authorized this specific class of purchase, (b) the amount and merchant match the authorization, and (c) the authorization has not expired or been revoked. Without this chain, disputes cannot be resolved, compliance cannot be demonstrated, and liability cannot be assigned.

3. No Stellar-Native Agentic Payment Rail

Stellar is the ideal settlement layer for agent commerce: 2-5 second finality, $0.00001 fees, native USDC, and Soroban smart contracts with programmable authorization. Yet no production tooling exists that connects AP2 or x402 to Stellar's capabilities in a developer-friendly SDK.

The Trust Vacuum — Before and After REAPP
Today's binary choice between full custody and human approval is replaced by REAPP's bounded delegation model enforced by Soroban.
