Screening cryptocurrency wallets is as fundamental as background checks in traditional finance. Every address has a history recorded immutably on the blockchain. This history reveals if it has interacted with hacked exchanges, ransomware operators, or sanctioned entities. For businesses, screening upon deposit prevents the acceptance of tainted funds. For individuals, it protects against receiving assets that could be blacklisted elsewhere. This process is a cornerstone of crypto hygiene. Make it a standard practice to conduct an aml check on any new counterparty’s wallet.
