KPMG Highlights x402 as 'Next Era' Payment Standard
A report from consulting firm KPMG has positioned the x402 protocol as a key internet-native payments standard for the future. The analysis highlights x402's role at the intersection of next-generation fintech and digital asset infrastructure. The protocol is designed to facilitate autonomous payments, stablecoin transactions, and embedded card acceptance, with Solana often cited as a core settlement layer.
- The x402 protocol, originally developed by Coinbase, is being positioned as a standard for machine-to-machine and AI-driven payments, activating the long-dormant HTTP 402 "Payment Required" status code. - Solana has emerged as a significant settlement layer for x402 transactions due to its high throughput and low transaction costs, which are essential for the high-frequency, low-value payments typical of AI and machine-to-machine interactions. - In early 2026, Solana captured nearly half of the x402 protocol's transaction share, with over 45 million cumulative transactions. At its peak in early 2026, Solana accounted for over 88% of all weekly x402 transactions. - Despite a surge in late 2025, with daily volumes reaching over $600,000, recent data from February 2026 shows a significant decline in weekly x402 transaction volume on Solana, dropping over 90% from its peak in December 2025. - Key players in the Solana x402 ecosystem include facilitators like Dexter and PayAI, which process the majority of the network's x402 transactions. PayAI has a native token (PAYAI) with a fixed supply of 1 billion tokens, which are fully liquid at launch. - A Solana x402 Hackathon took place in late 2025 to spur development, with over 400 project submissions. One of the main track winners was Intelligence Cubed (i³), a platform for tokenizing and trading AI models, which uses x402 for payments. - Other winning projects from the hackathon include PlaiPin, which enables IoT devices to make autonomous payments, and x402 Shopify Commerce, allowing stores to accept payments from AI agents. - The Solana ecosystem has shown its support for the x402 narrative by launching an official "x402 on Solana" Twitter account to highlight developments and projects utilizing the protocol.
