1. The first phase was about proving participation:
Visa’s Wirex USDC and EURC settlement on Stellar, and Mastercard’s MTN onboarding of Circle, Paxos, Fiserv and PayPal, show both networks entering onchain finance through partner-led experiments. This stage was about proving that blockchain settlement could connect with existing payment networks without disrupting the broader operating model.

2. The second phase moved onchain settlement closer to live network utility:
Visa’s expansion across 4 chains, 4 stablecoins and $2.5B in transaction volume shows a move toward broader multi-chain settlement capacity. Mastercard’s MTN expansion into EEMEA similarly points to stablecoin settlement moving from isolated pilots toward regional network deployment.

3. The third phase is about infrastructure ownership and governance:
Visa’s validator node on Circle’s Arc positions it as an infrastructure builder that can help govern the blockchain its settlement activity runs on. Mastercard’s $1.8B BVNK acquisition gives it direct control over a stablecoin infrastructure API layer inside MTN. This marks a deeper strategic shift from accessing onchain rails to influencing, operating and owning them.

Visa and Mastercard are no longer treating onchain infrastructure as an external layer to connect with occasionally. Their latest moves show a stronger push to shape the rails behind stablecoin settlement, either by helping govern blockchain networks or by bringing infrastructure providers in-house. For the card networks, the next stage of crypto and stablecoin competition will depend less on who launches the most pilots and more on who controls the settlement layer that institutions can trust and scale on
