Visa has launched its own validator node on the Tempo blockchain, a network built for real-time stablecoin payments. The payment giant developed the node over six months and now serves as an “anchor validator,” directly verifying transactions alongside other early participants like Stripe. This strategic move deepens Visa’s involvement in blockchain infrastructure as major payment firms expand their stablecoin capabilities.
Visa has launched a validator node on the Tempo blockchain, taking a direct role in verifying and processing transactions. The company said the node is operated in-house and was developed over six months, positioning it as an “anchor validator” alongside early participants including Stripe and Zodia Custody.
This role places Visa in the transaction validation layer, where it helps order and confirm payments. The move also supports network security and performance during this early phase.
Tempo is a Layer 1 blockchain designed for real-time payments and stablecoin-based transactions. Validators on the network can earn stablecoin-denominated rewards for packaging transactions into blocks.
The initiative adds to Visa‘s existing blockchain activity, including its recently announced role as a validator on the Canton Network. There, it works with financial institutions on privacy-focused onchain payment systems.
As stablecoins gain traction, 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.
Last month, Mastercard agreed to acquire stablecoin infrastructure company BVNK in a deal valued at up to $1.8 billion. Meanwhile, Visa has focused on building and operating its own systems.
In July, the company expanded its settlement platform to support tokens and networks including Stellar and Avalanche. It also expanded its stablecoin card partnership with Bridge to 18 countries in March.
According to DefiLlama data, stablecoin market capitalization stood at nearly $319 billion. This represents an increase from about $307.5 billion at the start of the year.
