Stablecoin News
Visa has launched a validator node on the Tempo blockchain, taking a direct role in confirming and processing transactions on a network built for real-time stablecoin payments. The company said the node is operated using its own internal infrastructure and was built over six months in collaboration with Tempo's engineering team.
Tempo is a layer-1 blockchain designed specifically for real-time payment settlement using stablecoins. Validators on the network are responsible for ordering and confirming transactions and maintaining the ledger and can earn stablecoin-denominated rewards when selected to produce new blocks. Visa holds the position of anchor validator alongside Stripe and Zodia Custody during the network's early phase.
Operating a validator node places Visa inside the transaction confirmation layer rather than at the settlement edge. The company said the node contributes to network security and transaction processing performance. Visa is already a validator on the Canton Network, where it works with financial institutions on privacy-focused on-chain payment infrastructure.
Visa has been building out its blockchain capabilities across several networks. In July, the company expanded its settlement platform to support tokens such as PayPal USD and Euro Coin, as well as networks including Stellar and Avalanche. In March, it extended its stablecoin card partnership with Bridge to 18 countries, with plans to cover more than 100 markets by year-end.
Other major payment companies have been pursuing similar expansions. Stripe acquired stablecoin platform Bridge for $1.1 billion in October 2024 and has since introduced stablecoin-based accounts for businesses in more than 100 countries. Mastercard agreed last month to acquire stablecoin infrastructure firm BVNK in a deal valued at up to $1.8 billion, giving it direct access to stablecoin payment rails across more than 130 countries.
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, according to DefiLlama data. The Visa validator launch represents the company's most direct operational role in a public blockchain network, shifting its position from one that settles payments to one that also validates them.
