Mastercard Verifiable Intent, draft v0.1 · checked locally in your browser

A Verifiable Intent chain, checked the way a dispute would

Verifiable Intent defines signed evidence of what a shopper delegated to her agent. Its security model says it is evidence only: it defines no procedure for disputes. Here readback-core checks the chain VI's own example produces (Apache-2.0), as the payment network sees it: the issuer's, the shopper's and the agent's signatures, the bindings between the three layers, and the amount, payee and card.

Also checked: Google's AP2 v0.2 mandate. The issuer key below is the demo key VI publishes with its examples, not a real card issuer's key. This page is not affiliated with Mastercard.

L1: the issuer's credential for her key (SD-JWT)

L2: her mandate, as disclosed to the network (SD-JWT)
