Comparison

Visa protects the budget. SettleProof protects the outcome.

Visa-style pre-purchase guardrails (Stripe Agent Toolkit, Crossmint, Visa Intelligent Commerce) cap how much an agent can spend before the transaction. SettleProof, powered by AAP, closes the loop on what happens after: deterministic settlement when delivery is proven, deterministic refund when it isn't.

Why the gap matters

Chargebacks are projected to hit $28.1B in merchant losses by 2026, with global dispute volume rising from 238M (2023) to 337M (2026) — a 42% jump (Ethoca / Chargebacks911 2026 Outlook). Agent-initiated transactions amplify both sides: agents fan out requests at machine scale, and friendly-fraud detection wasn't designed for non-human buyers.

Morgan Stanley Research estimates $190–$385B of U.S. e-commerce will be agent-mediated by 2030. a16z's Sam Broner argues stablecoin thesis frames why programmable settlement rails matter — SettleProof is the attestation layer that makes that practical.
