Solana Foundation joined Visa, Mastercard, Stripe, Google, and Amazon in a Linux Foundation project to standardize AI agent payments, as agents settled an estimated $31B on Solana in 2025.
Decoder
- x402: Open standard protocol for agentic payments, now stewarded as a Linux Foundation project. Defines how AI agents authenticate, authorize, and settle financial transactions.
- Agentic payments: Financial transactions initiated and executed autonomously by AI agents rather than humans.
- SPL: Solana Program Library, Solana's token standard. Confidential SPL transfers use zero-knowledge proofs to hide transaction amounts.
- Ephemeral rollup: Temporary execution environment that processes transactions off-chain for privacy or batching, then commits final state to the main chain.

The Solana Foundation joined the x402 Foundation as a Linux Foundation project in April, aligning with Visa, Mastercard, Stripe, Google, Amazon, Coinbase, Circle, and Cloudflare to co-steward the open standard for agentic payments. Solana accounts for about 65% of x402 transaction volume year-to-date, with agents selecting the chain for sub-cent, stablecoin-settled, pay-per-use economics. April integrations included Alchemy, Messari, Zerion, and Crossmint (with Mastercard), while MoonPay eliminated stablecoin onramp fees for AI agents on Solana, and Magicblock shipped private payments via confidential SPL transfers with ephemeral rollup delays. MiloOnChain crossed $600K monthly volume and 250K agentic transactions with win rate climbing from 15% to 46.1%, as AI agents settled an estimated $31B in payment volume on Solana in 2025 outside traditional banking rails.
