Mastercard is named as a Tempo/MPP design partner for agent payments

Tempo’s mainnet note lists Mastercard among partners working on mainnet payment use cases, and says MPP is extensible to card networks. This is partnership language, not a settlement-volume disclosure. zFinia files it as TIER_B/A official corporate communication depending on the primary source.
