AI Agents Flood x402 on Solana with 3.3M USDC Transfers in a Single Week

The x402 protocol has enabled AI agents to initiate 3.3 million USDC transfers on Solana over the past week, with a cumulative total of 5.1 million transfers over the last 90 days.

This rapid growth is facilitated by Solana's sub-second finality and negligible transaction fees, making it an ideal platform for micropayments that would be impractical on higher-fee chains.

The x402 protocol allows AI agents to settle payments on-chain in USDC when a server responds with a 402 status code containing payment details. This eliminates the need for human intervention and enables seamless, automated transactions.
