Linux Foundation, together with Coinbase, established the x402 Foundation. This step aims to standardize agent-based AI payments in crypto and fiat infrastructures. Blockchain giants like Solana Foundation are also included.
Founding Members of the x402 Foundation and SOL Contribution
Google, Microsoft, Amazon Web Services, American Express, Mastercard, Visa, Cloudflare, Shopify, Stripe, Circle, Base, Polygon Labs, SOL detailed analysis, Thirdweb and KakaoPay are among the foundation’s founding members. Linux Foundation CEO Jim Zemlin emphasized the open-source nature of x402 by stating that the internet was built with open protocols. Coinbase stated that the protocol has gained a neutral and non-profit structure. Solana Foundation’s participation strengthens the SOL ecosystem for high-speed payments.

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.

B2C2’s SOL Stablecoin Preference Strengthens x402
SBI Holdings’ B2C2 platform selected Solana as the primary stablecoin network for institutional customers. This supports x402’s fiat-crypto bridge; SOL futures volume may increase. SOL’s low fees and speed are ideal for AI agent payments.
Long-Term Impact of the x402 Foundation on the SOL Ecosystem
The foundation will make Web3 payments mainstream with open standards. SOL Foundation’s role heats up competition with POL analysis, while ETH EIP-3009 integration will offer hybrid solutions. Investors should monitor S1 support.
