💳 Tempo Launches Public Testnet
Testnet Announcement: Tempo launched its public testnet on December 9th, allowing developers to build on this Ethereum-compatible Layer 1 blockchain focused on payments. The project, incubated by Stripe and Paradigm, raised $500 million in Series A funding at a $5 billion valuation, led by Thrive Capital and Greenoaks, with participants including Sequoia Capital and Ribbit Capital. Initial design partners like OpenAI, Shopify, Visa, Deutsche Bank, Anthropic, and Nubank tested workloads such as remittances. Since launch, 14 additional partners joined, including Brex, Klarna, Mastercard, UBS, and Deel, bringing the total to over 27 firms, alongside 40 infrastructure partners.
Technical Features: The testnet features dedicated payment lanes with reserved blockspace to avoid congestion and target fees at one-tenth of a cent per transaction. Stablecoin-native gas enables direct payment of fees in USD-denominated stablecoins, avoiding volatility. A built-in DEX optimizes for stablecoins and tokenized deposits, supporting automatic conversions and liquidity consolidation. Transfers include metadata like invoice numbers for reconciliation. Consensus provides fast finality with blocks every 0.5 seconds via four initial Tempo-operated validators, expanding toward permissionless operation. Wallets support gas sponsorship, batching, and passkeys.
Stablecoin Chains Context: Tempo joins a growing group of Layer 1 blockchains designed for stablecoin and payments use cases. Plasma launched its mainnet beta on September 25th with $2 billion in initial stablecoin liquidity and zero-fee USDT transfers. Stable activated its StableChain mainnet on December 8th, using USDT for gas fees and introducing the STABLE token. Circle's Arc began its public testnet on October 28th, emphasizing USDC integration, predictable fees, and institutional participation from firms like Visa and BlackRock. These networks reflect increasing focus on infrastructure optimized for low-cost, high-throughput stablecoin transactions.
