Visa has deployed a validator node on the Tempo blockchain, taking a hands-on role in verifying and processing transactions on a network built for real-time stablecoin payments. The node is operated on Visa’s own infrastructure and was developed over roughly six months in cooperation with Tempo’s engineering team. Visa joins early participants such as Stripe and Zodia Custody as an “anchor validator,” helping to secure and stabilize the network during its initial phase.
As a validator, Visa participates in the transaction validation layer: ordering and confirming payments, maintaining the ledger, and contributing to network performance and security. Tempo is a Layer 1 blockchain designed specifically for low-latency, stablecoin-based payments. Validators on Tempo are selected to package transactions into blocks and can receive stablecoin-denominated rewards for doing so, but a Visa spokesperson said the company’s primary emphasis at this stage is on the strategic and technical aspects of running a validator rather than on the economic incentives.
This move expands Visa’s broader blockchain activity. The company recently agreed to operate as a validator on the Canton Network, a project focused on enabling privacy-preserving on-chain payments in partnership with financial institutions. Visa has also continued to enhance its settlement and token support: in July it broadened its settlement platform to handle tokens such as PayPal USD (PYUSD) and Euro Coin (EURC) and to interoperate with networks including Stellar and Avalanche. Earlier in the year, Visa extended its stablecoin card partnership with Bridge to 18 countries, with plans to reach more than 100 markets by year-end.
The Tempo validator announcement comes as payment firms accelerate investments in stablecoin infrastructure. In October 2024, Stripe completed a roughly $1.1 billion acquisition of the stablecoin platform Bridge and rolled out stablecoin-based account services for clients across more than 100 countries, enabling businesses to send, receive, and hold US-dollar stablecoins similarly to bank balances. Mastercard has also moved into the space with a proposed acquisition of BVNK for up to $1.8 billion; BVNK provides infrastructure for stablecoin payments, fiat-crypto conversion, and global settlement in over 130 countries.
Market indicators show steady growth in the stablecoin sector: DefiLlama data put total stablecoin market capitalization at about $319 billion at the time of reporting, up from roughly $307.5 billion at the start of the year. Visa’s new role on Tempo is another sign of incumbents building native infrastructure to support faster, token-based payment rails as stablecoins gain traction in commerce and cross-border settlement.
