Visa, Stripe, and Zodia Custody Become Early Validators of the Tempo Payment Blockchain

According to The Block, Visa, Stripe, and Zodia Custody—a digital asset custody firm backed by Standard Chartered Bank—have become the first validators on the Tempo payment blockchain. Tempo is an Ethereum-compatible Layer 1 blockchain designed specifically for high-throughput payments and stablecoin settlement, primarily targeting large institutions. Validators are responsible for verifying, ordering, and finalizing on-chain transactions, and are typically mature organizations with global operational capabilities. Tempo was incubated by Stripe and Paradigm, launched its private testnet in September 2025, and closed a $500 million Series A funding round in October at a valuation of approximately $5 billion. Recently, Tempo introduced its “Agent Payments” protocol—executed by AI agents—and has attracted infrastructure integrations including RedStone.
