Solana's share of the x402 micropayment market has fallen to approximately 49.7%, down from a peak of over 88% earlier this month, according to SolanaFloor data. This decline is attributed to increased competition from Polygon. The total number of x402 transactions across all chains has surpassed 120 million, with Solana contributing over 45 million transactions and a cumulative payment amount exceeding $41 million, of which Solana accounts for about $16.4 million. Weekly data indicates a significant drop in Solana's x402 transaction volume, plummeting over 90% from a high of approximately 6.8 million transactions in December 2025 to under 510,000 transactions in the week ending February 9, 2026.
