The rise of Coinbase’s x402 fits into a larger shift toward agentic AI, as noted in a16z Crypto’s 2025 State of Crypto report.
By 2030, autonomous transactions could top $30 trillion, as AI systems handle payments for computing, storage, and even self-driving taxis — all via stablecoins.
Coinbase developers say x402 enables this by letting AIs make direct, verifiable on-chain payments without human help — a key step toward a machine economy.
