Visa has officially launched a validator node on the Tempo network, marking a significant step in the payments giant’s push into blockchain infrastructure. Tempo, a purpose-built Layer-1 blockchain designed for agentic commerce and real-time payments, now counts Visa, Stripe, and Zodia Custody by Standard Chartered among its first external validators.

The validator node was configured and managed entirely in-house by Visa following six months of joint engineering work with Tempo’s team. Rather than relying on third-party operators, Visa integrated its secure infrastructure directly into the Tempo network — positioning itself as an anchor validator during this initial phase of network growth.
