Agentic payments on Base, powered by Coinbase's x402 protocol, have exceeded 100 million cumulative transactions within three quarters, surging from near-zero in Q3 2025. The growth was initially driven by meme coin farming, particularly the PING token, which caused a 10,000% weekly spike. By early 2026, transactions of $1+ represent 95% of total volume, up from 49% in early 2025, signaling a shift toward meaningful value transfer. Tester-to-payer conversion rates improved 4x in six months, and weekly wallet retention is trending upward, indicating users are integrating agentic payments into recurring workflows. x402 payers are typically newer wallets (average age 197 days vs. 423 for other Base users), hold 26 different tokens on average (vs. 4), and receive 12x higher capital inflows. The protocol allows AI agents to autonomously execute micro-transactions via HTTP 402 responses, closing a gap between AI operations and legacy payment rails. While still early, the data suggests x402 is attracting new users to Base and building infrastructure for machine-to-machine payments.
