The regional bank tokenized deposit network on ZKsync reveals a strategic pivot most are missing. These aren't experiments in blockchain efficiency—they're defensive positioning against the coming wave of AI agent payment flows that will bypass traditional correspondent banking entirely. When autonomous agents begin executing millions of micro-transactions daily, the existing ACH rails become a bottleneck. Banks understand that agent-to-agent commerce won't wait for T+2 settlement or tolerate correspondent bank fees. By tokenizing deposits now, they're creating the infrastructure to capture agent payment flows before crypto rails make them obsolete. The ZKsync choice signals they expect this transition within 18 months, not years. The velocity of agent commerce will dwarf human transaction patterns, and whoever controls the settlement layer controls the economic relationship with the autonomous economy.
