x402 Protocol: Automatic AI Payments with HTTP 402 and EIP-3009
The x402 protocol combines the HTTP 402 “Payment Required” status code with Ethereum Improvement Proposal 3009 (EIP-3009) to enable AI agents to transfer funds without manual approval. This enables micropayments on fast chains like $SOL. The protocol supports ERC-4337 account abstraction to minimize gas fees and becomes compatible with Solana’s Proof-of-History mechanism.
Fluctuations in x402 Transaction Volume and $SOL Relationship
According to Dune Analytics data, the protocol's weekly transaction volume peaked at 13.7 million in November 2025, dropping to 29 thousand - 1.1 million in 2026. $SOL's high TPS (65,000+ ) can carry x402 traffic; Polygon Labs and Base's participation increases $ETH-$POL competition.
