SOL Solana surpassed Base for the first time in terms of the number and amount of x402 transactions
According to Artemis data released by SolanaFloor on September 3, Solana surpassed Base for the first time in terms of the number and transaction volume of x402 transactions. In the last week of August, Solana processed more than 90% of x402 transactions, marking a major shift in the way stablecoin payments are processed between applications and AI agents in the blockchain network.
Solana dominates x402 activity in 2026
Artemis data shows that x402 usage on Solana increased significantly in the week ending August 31. The network has previously been the most traded platform for x402 and has now surpassed Base. Although transaction volumes may sometimes be exaggerated due to micropayments, accompanying transaction volume data confirms that Solana has an advantage in both qualitative and quantitative activities during this period.
This development marks a critical turning point in Solana and Base's competition for x402 transaction streams. Solana's market share continues to rise as protocol developers step up testing automated and programmatic stablecoin payments. Despite this week's dramatic surge, analysts warn that a single data point does not establish a long-term trend.
Protocol Background: How to implement programmatic stablecoin payments in x402
The x402 protocol was developed by Coinbase and utilizes HTTP's 402 payment status code to facilitate automatic payments in stablecoins programmed by AI proxies and decentralized applications. The agreement allows digital agents to pay directly for APIs, data and services, supporting multiple networks including Solana and Base.
Solana's infrastructure is known for its low cost and high speed settlement, making it attractive for repetitive, small-value transfer use scenarios. In May 2026, Rich Widmann of Google Cloud described Solana as the "right choice for settlement," emphasizing its role in achieving smooth machine-to-machine (M2M) payments between artificial intelligence systems.
Mini Dictionary: x402 is a payment protocol designed by Coinbase that uses HTP402 status code to implement stablecoin payments between software agents, especially to access APIs and services without human customer intervention.
Coinbase stated that x402 allows AI agents and applications to send and receive stablecoin payments for APIs, content and services, covering multiple networks such as Solana and Base.
Impact on stablecoin payments and Solana practicality
Solana's dominance in recent x402 activity may solidify its reputation as the preferred settlement network for stablecoin transfers and machine-driven payments. As of now, online reports show that since the protocol was launched in Solana, more than 35 million x402 transactions have been processed, with a total transaction volume of US$10 million.
However, increased x402 usage does not necessarily translate into increased direct demand for SOL tokens, as most transactions are settled in stablecoins. Continued commercial use from AI agents, applications and the corporate world will be a stronger indicator of the sustainability utility of the network.
Despite the surge in x402 transactions, observers emphasize that organic economic activity and recurring payment behavior will ultimately determine whether Solana can maintain its lead in the coming months.
Outlook: Can Solana's lead in x402 events continue?
The key question is whether Solana's surge in x402 activity can last for several weeks, indicating stable economic demand. Market participants will focus on continued trading volume and repeated commercial payments to assess long-term adoption. Base continues to support x402 transactions, and Coinbase also emphasizes that the protocol is built for multi-network use.
For developers, businesses and investors, the extensions used by x402 indicate a broader trend towards automated on-chain payments and programmatic commerce. Whether Solana's current advantages will become permanent remains to be seen, depending on consistent adoption rates and transaction volume over time.
