Payment giants Stripe, Visa, and Standard Chartered’s Zodia Custody have become validators on the Tempo blockchain network. The firms, which collectively process trillions of dollars annually, are now directly validating the crypto network built for real-time payments. All three were design partners since Tempo’s inception and are actively building payment flows on the protocol.
Visa said Tuesday it has become an “anchor validator” for the Stripe-backed Tempo blockchain network, joining Stripe itself and Zodia Custody by Standard Chartered. The companies collectively process trillions of dollars in payment volume every year across nearly every country in the world.
The firms have been design partners of Tempo since day one and are building payment flows on the protocol. Visa said its validator node was configured and managed in-house following six months of joint work with Tempo’s engineering team.
“We’ve spent years building our expertise in blockchain, and now we’re expanding that work by running critical blockchain infrastructure ourselves,” said Visa Head of Crypto Cuy Sheffield. “By operating a validator on Tempo, we’re extending Visa’s commitment to reliability, security, and trust into blockchain networks.”
The validator announcements come as Tempo expands its infrastructure capabilities. The blockchain launched its mainnet in March and launched the Machine Payments Protocol, an open standard for AI agents.
“Visa processes billions of transactions across nearly every country in the world. That kind of operational rigor is exactly what we look for in validators on Tempo,” said Tempo’s go-to-market lead, Nischay Upadhyayula. Additional validators are set to be announced in the future.
