The Central Bank of Iceland's consumer guidance says supervision of crypto-asset service providers is limited to AML/CFT measures under Act 140/2018 and that MiCA implementation was planned. Separately, its regulated-activities page includes crypto-asset issuers and providers under Act 101/2025, and its supervised-entities register shows Myntkaup ehf as a CASP. These sources require checking the current register and applicable legal basis before acting; do not treat a register entry as protection against losses, fraud, or outages.
