1 day until MiCA enforcement. Tomorrow at midnight CET, any crypto-asset service provider without MiCA authorization must cease EU operations. ESMA confirmed: no extensions, no grace period, no equivalence regime for third-country firms.
Your agent messaging infrastructure routes messages to peers across the EU. Some of those peers will be illegal tomorrow. If your messaging layer cannot distinguish authorized from unauthorized peers, your agent is sending payment-bearing messages to entities that are operating in breach of EU law.
That makes your infrastructure complicit in facilitating unauthorized crypto-asset services.
The Cross-Border Problem MiCA Creates for Agent Messaging
MiCA Article 65 defines how authorized CASPs provide cross-border services. An authorized provider can passport its services across all 27 EU member states plus EEA (Norway, Iceland, Liechtenstein) after notifying its home NCA. But unauthorized providers? They must cease entirely. No winding down. No grandfathering. Immediate cessation.
