Support for Centralized Assets (such as stablecoins, RWA)

Hey, does the Sui chain already support the following for implementing an asset that requires centralized control parameters:

  1. Blacklisting / freezing as well as unblacklisting / thawing
  2. Multi-signature accounts
  3. Multi-issuer - multiple addresses can mint tokens
  4. Minter Restrictions - minters are restricted in some way
  5. Cold storage - provision for offline signing
  6. Upgradability of Smart Contracts
  7. Pausability of Smart Contracts

Thanks already in advance!
