WLFI Launches AgentPay SDK for USD1 Stablecoin on March 19
WLFI has entered the rapidly expanding market for AI-driven payments, announcing the launch of its AgentPay SDK on March 19, 2026. The software development kit is designed to establish WLFI's native USD1 stablecoin as a core payment layer for the "agentic economy," where autonomous AI agents transact with online services.
This strategic initiative aims to drive significant utility for the USD1 stablecoin and the broader WLFI ecosystem. By providing foundational infrastructure for machine-to-machine payments, WLFI seeks to capture a share of a high-growth technology sector where AI systems will increasingly need to pay for data, APIs, and other computational resources autonomously.
Stripe-Backed Tempo Gains First-Mover Advantage with March 18 Launch
WLFI's announcement comes just one day after the mainnet launch of Tempo, a payments-focused blockchain incubated by financial giants Stripe and Paradigm. On March 18, Tempo unveiled its own solution, the Machine Payments Protocol (MPP), an open standard co-authored with Stripe to enable seamless transactions between AI agents.
Tempo's launch was bolstered by immediate support from major financial players. Global payments firm Visa extended MPP to support card-based payments, while Lightspark integrated it for Bitcoin payments on the Lightning Network. The protocol's design as a flexible, open standard has drawn early praise from industry leaders.
A few things I like about MPP (machine payments protocol) Payment-method agnostic (supports stablecoins on Tempo, Stripe, cards, Bitcoin lightning, etc) Open and extensible (without our permission) Streaming payments (via state channels) Minimal and efficient

Payment Giants Race to Build Infrastructure for Agentic Economy
The competing launches from WLFI and Tempo underscore a fierce industry-wide race to build the financial rails for AI. The concept of an "agentic economy" has attracted significant investment and development from top technology and crypto firms. This sector is viewed as the next major frontier for internet infrastructure, where the volume of machine-driven payments could eventually eclipse human transactions.
Other established players are already active in the space. Coinbase has been promoting its x402 standard to facilitate agentic stablecoin payments, which was recently integrated into a developer toolkit from Sam Altman’s World project. The Ethereum Foundation has also signaled its focus on the technology, backing an open-source protocol from Google and exploring the ERC-8004 proposal to enable seamless agent transactions on its blockchain.
