• Competitive urgency: Tempo, Stripe, Visa, Lightning have official MPP methods. Sui has a full agent platform (t2000). Solana Foundation is building an official MPP SDK. Stellar just submitted a spec (PR #199). Canton needs MPP support to participate in the emerging agentic economy.
• Upstream contribution: Canton method spec submitted to tempoxyz/mpp-specs (PR #198), positioning Canton alongside Tempo, Stripe, and Visa.
• All code is open-source (Apache 2.0 / MIT dual license).
