In brief
CIP-0113 gives Cardano token issuers built-in tools to freeze and seize assets, and to control who can receive their tokens.
Enforcement takes place on-chain in the Cardano ledger during minting, burning, and transfers. The upgrade does not require a hard fork.
ADA itself cannot be frozen, but its price fell 8.71% to $0.25397 as the broader crypto market also declined.
