Crypto is emerging as the payment infrastructure best suited for AI agents, echoing comments attributed to CZ at Token2049 in Dubai last year. The statement argues that AI systems cannot rely on traditional consumer payment methods such as cards or SMS-based verification when moving value autonomously. The view centers on the need for instant, low-value, high-frequency transactions between non-human counterparties. In that framing, legacy banking settlement and card networks are presented as too slow or impractical, while crypto rails are described as the only system built to support autonomous machine-to-machine payments at scale.
