Mastercard and Australian banks complete country's first authenticated agentic transactions
CBA and Westpac cards complete Australia's first fully authenticated agentic payments via Mastercard Agent Pay using Maincode's Matilda LLM in a controlled test.
The Australian pilot is the first authenticated agentic transaction outside the US for Mastercard Agent Pay (2025-w18-payments-mastercard-agent-pay), executed via CBA and Westpac — two of Australia's Big Four banks — using local LLM provider Maincode's Matilda model rather than a US foundation-model vendor. The structural pattern (network plus local issuers plus regional LLM) repeats four weeks later in Europe with Santander (2026-w10-pilots-santander-mastercard-europe-first-payment). The pilot follows the Citi and US Bank live-issuance milestone (2025-w44-payments-mastercard-agent-pay-live-us) by three months and precedes the Q1 2026 disclosure of near-universal global card coverage (2026-w18-payments-mastercard-agent-pay-q1-milestone). The Maincode involvement places a non-US frontier-model lab inside Mastercard's launch geography.
