Coinbase can earn from growing agentic payments through Base transaction fees and yield on dollars backing USDC on Base. Its x402 protocol lets agents pay instantly for web services with stablecoins; cumulative Base x402 transactions rose from 1.5K to 138.5M in five quarters. After a Q4 2025 testing jump, quarterly activity rose from 14M to 18M to 23M in 2026, which looks like accelerating organic use, not just testing. x.com
