Visa joins Tempo validators

Visa is now running a validator node on Stripe-backed Tempo, taking a direct role in checking and securing transactions on the payments blockchain. (visa.com) Visa said on Tuesday, April 14, 2026, that it configured and operates the node in-house after about six months of work with Tempo’s engineering team. Stripe and Zodia Custody, a digital-asset firm backed by Standard Chartered, are joining as the first external validators on the network. (visa.com) A validator is one of the computers that confirms transactions and helps keep a blockchain in sync, like a shared ledger that many parties update together. Tempo says its mainnet is live and describes the network as a general-purpose blockchain built for payments, with low fees and high throughput. (docs.tempo.xyz) Tempo was incubated by Stripe and Paradigm and is built around stablecoins, which are digital tokens designed to track assets such as the United States dollar. Tempo says existing blockchains are often built for broad computing or trading, while its system is tuned for real-world payment volume. (tempo.xyz) The validator push comes as Tempo expands beyond its initial operators and says it plans to move toward permissionless validation, where more outside participants can help run the network. Its documentation says the chain is designed for instant, deterministic settlement and lets users transfer value and pay network fees in stablecoins. (tempo.xyz) (docs.tempo.xyz) Visa has been building stablecoin tools for several years, including settlement support in USD Coin and a platform for banks to issue tokenized money. Cuy Sheffield, who leads Visa’s crypto work, told CoinDesk the company’s engineers have focused on stablecoins for seven years. (coindesk.com) Tempo and its backers are pitching the network for round-the-clock cross-border transfers, tokenized deposits and software-driven payments between machines. The Block reported that Tempo recently launched mainnet alongside an agentic payments protocol meant to let software agents transact. (cryptotimes.io) (theblock.co) For Visa, the step moves it from using blockchains for selected settlement products to helping operate the infrastructure underneath one. For Tempo, adding Visa, Stripe and Zodia gives the young network payment companies with global reach as it tries to build out its validator set. (visa.com) (coindesk.com)
