createToken(string tokenName, string tokenSymbol, uint8 tokenDecimals) → contract ExpandedIERC20 newToken (external)

The caller will become the only minter and burner and the new owner capable of assigning the roles.


  • tokenName: used to describe the new token.
  • tokenSymbol: short ticker abbreviation of the name. Ideally < 5 chars.
  • tokenDecimals: used to define the precision used in the token's numerical representation.

Prevents a contract from calling itself, directly or indirectly. Calling a nonReentrant function from another nonReentrant function is not supported. It is possible to prevent this from happening by making the nonReentrant function external, and making it call a private function that does the actual state modification.


Designed to prevent a view-only method from being re-entered during a call to a nonReentrant() state-changing method.
