Wallets as the New Compliance Layer
On March 16, 2026, the French Treasury (DG Tresor) and the ACPR published updated joint guidelines on the implementation of asset-freezing measures. The text is formally 'explanatory' rather than binding in itself, but that should not mislead anyone. Its purpose is to remove ambiguity around how financial institutions, payment providers, and crypto-asset service providers are expected to implement sanctions-related asset freezes in practice. This is not a narrow compliance memo, it's a blueprint for how regulated financial systems are now expected to behave.
