MiCA July 1 Is Not a Legal Date. It Is a Client Migration Problem.

On April 17, 2026, ESMA said the MiCA transition period expires across the EU on July 1, 2026. After that date, unauthorised CASPs serving EU clients are in breach and must stop offering those services.

That is not a policy note. It is a product switch.

Client migration sounds administrative. It is not.

Accounts move. Assets move. Custody changes. Risk files change hands. Support scripts get written in a rush. Users try to withdraw at the last minute. Bad actors use confusion as cover.

By June, a CASP should know which EU clients can stay, which must migrate, which must be offboarded, and which wallets require extra review before release.

The answer cannot live in a spreadsheet owned by one person. It must appear in onboarding, withdrawals, support, audit logs, and customer notices.

Wind-down does not mean weak controls. If anything, it raises the temperature.

Large withdrawal waves, dormant accounts waking up, address changes, rushed beneficiary updates, and missing Travel Rule data should all trigger review.

Map EU exposure. Decide service status by client segment. Prepare migration notices. Screen withdrawal wallets. Preserve check history. Retain evidence. Assign escalation owners.

A licensed story is useless if operations cannot execute it on July 1.
