The European Union is set to enforce MiCA, a crypto law that mandates national regulators to license and supervise service providers. While the regulation is EU-wide, countries can implement slightly different technical standards that crypto firms must adhere to. MiCA's specialized rules for stablecoin issuers will take effect in a few months, followed by licensing and other requirements for crypto firms broadly in December. Each jurisdiction must transpose the EU regulation into local law, select which of their regulators will oversee crypto, and prepare to authorize token issuers and other service providers. Regulators are facing challenges in implementing the new legislation, particularly in terms of licensing requirements, and each country's crypto industry has its own concerns about implementation and proposed laws.
