The x402 protocol, designed for blockchain-based micro-payments, has processed over 120 million transactions, with Solana emerging as a key participant. While Base leads with $21.5 million in cumulative transaction volume, Solana recently captured over 88% of weekly transaction share, though this figure later dropped to 49.7% following a surge on the Polygon platform. Payment facilitators Dexter and PayAI handle the majority of Solana's transactions. However, both transaction volume and value have seen significant declines in recent weeks, with data suggesting that a substantial portion of peak activity was inorganic, raising questions about the sustainability of Solana's adoption despite its strong technical suitability for high-frequency, low-value payments.
