# Tempo RPC and network details

Source: https://www.alchemy.com/rpc/tempo

Tempo is a Layer-1 blockchain backed by Stripe and Paradigm that’s purpose-built for payments at internet scale. Unlike general-purpose chains, Tempo is architected around the demands of production payment systems: predictable fees, sub-second finality, over 100K TPS, and dedicated payment lanes that guarantee blockspace for transfers even during congestion. Tempo also introduces the Machine Payments Protocol (MPP), an open standard for how AI agents pay for services, along with native account abstraction, a compliance-ready token standard (TIP-20), and the ability to pay gas in stablecoins.
