The Gateway to the Autonomous AI Economy.
PayNode is a stateless, non-custodial M2M (Machine-to-Machine) payment gateway built for the Agentic Era. This meta-repository serves as the central hub, brand asset kit, and architectural source of truth for the entire PayNode ecosystem.
The PayNode protocol is distributed across specialized repositories to ensure modularity and high performance.
