Institutional lockout — exchange custody (2021)
SurvivesCase description
The G7 published recommendations on cryptocurrency regulation in July 2021, calling for mandatory registration of cryptocurrency service providers and application of AML/KYC standards to DeFi. The regulatory signal prompted dozens of exchanges globally to tighten KYC requirements mid-cycle. Customer accounts mid-verification had their status reset, requiring re-submission of documents.
