Top Blockchains Continue to See Rapid Growth in AI Agent Payments. This Is the 1 Crypto You Need to Buy Right Now.
Key Pointsx402, a payments protocol for AI agents, has seen significant growth over the last year.
In October 2025, 138.5 million payments were made on the Base blockchain using x402, a payment protocol designed for AI agents, according to a Chainalysis report. This represents a significant increase from 58,800 transactions in Q3 2025. AI agent payments are seen as a promising growth driver in the crypto market, with Solana (SOL -3.01%) being one of the cryptocurrencies best positioned to benefit from this trend.
x402, developed by Coinbase, creates payment terms for protected digital resources like API calls or paywalled articles. AI agents can sign payment authorizations and make small transactions, typically under $0.10, which are too small for traditional payment networks due to high fees and chargeback risks. Most agent payment volume settles on Base, Solana, or Polygon, with Base currently leading in cumulative settled transactions and payment volume on x402. However, Base doesn't have an associated crypto token for investment.
Solana, which has overtaken Base in daily activity at several points this year, is known for its fast blockchain and extremely low crypto transaction fees. It has introduced batch settlement on x402 through the PayAI Network and BlockRunAI, allowing transactions to be bundled into a single on-chain settlement. This saves fees and reduces latency significantly.
Despite the small transaction amounts, AI agent transactions haven't driven much economic activity yet, with only $25.6 million appearing plausible after removing suspicious activity.
While Solana isn't making a lot of money from agent transactions, it is building the infrastructure for success as these payments grow. The stablecoin supply on Solana reached a record $17.3 billion in September, with daily active stablecoin addresses reaching 888,000, a 269% increase from a year earlier. With Solana trading about 64% below its all-time high of $293 in January 2025, investors have an opportunity to get in early on a blockchain that could take off if AI agent payments continue to grow.
