Authorisation history
Firefish first appears in the MICA Watch snapshot of 1 January 2026 — it was not in the copy of the register we took before that. This is when the record entered our archive, which is not necessarily the date the authority granted it: the register itself gives 2 January 2026.
Its record has changed 1 time across our 17 snapshots:
| Snapshot | Services | Passported to |
|---|---|---|
| 1 January 2026 | 4 | 2 countries |
| 5 August 2026 | 4 | 30 countries |
Compiled from 17 snapshots of the ESMA register taken between 11 July 2025 and 18 August 2026. ESMA publishes the register as a weekly overwrite and keeps no public archive, so earlier states are not available from the source.
