Visa has launched a validator node on the Tempo blockchain, taking a direct role in verifying and processing transactions on a network designed for real-time stablecoin payments.
Visa said the node is operated in-house using its own infrastructure and was developed over six months working with Tempo’s engineering team, positioning the company as an “anchor validator” alongside early participants including Stripe and Zodia Custody.
The role places Visa in the transaction validation layer, where it helps order and confirm payments while supporting network security and performance during the network’s early phase.
Tempo is a Layer 1 blockchain designed for real-time payments and stablecoin-based transactions, with validators responsible for confirming transactions and maintaining the network’s ledger.
Validators on the network can earn stablecoin-denominated rewards when selected to package transactions into blocks, according to the announcement. However, a company spokesperson told Cointelegraph that “Visa’s primary focus in this phase is on the strategic and technical role of operating a validator, rather than on economics.”
The move adds to Visa’s existing blockchain activity, including its recently announced role as a validator on the Canton Network, where it works with financial institutions on privacy-focused onchain payment systems.

Payment companies expand stablecoin infrastructure
As stablecoins gain traction in payments, major payment companies are expanding infrastructure that connects traditional finance with blockchain-based settlement.
In October 2024, Stripe finalized a $1.1 billion agreement to acquire stablecoin platform Bridge. The following year, it introduced stablecoin-based accounts for clients in more than 100 countries, allowing businesses to send, receive and hold US-dollar stablecoins similar to traditional bank balances.
Last month, Mastercard agreed to acquire stablecoin infrastructure company BVNK in a deal valued at up to $1.8 billion. BVNK enables businesses to send and receive stablecoin payments, convert between fiat and crypto, and operate across more than 130 countries.
Meanwhile, Visa has focused on building and operating its own systems. In July, the company expanded its settlement platform to support tokens such as PayPal USD (PYUSD) and Euro Coin (EURC), as well as networks including Stellar (XLM) and Avalanche (AVAX).
In March, it also expanded its stablecoin card partnership with Bridge to 18 countries, with plans to reach more than 100 markets by year-end.
According to DefiLlama data, stablecoin market capitalization stood at nearly $319 billion at the time of writing, up from about $307.5 billion at the start of the year.
