  • function decreaseAllowance(address spender, uint256 subtractedValue) public returns (bool)


  • function cap() public view returns (uint256)
Supports flexible rules for FREEZING

Flexible rules by external contracts with interface of:

 * @dev Interface of an allocation contract.
interface IAllocation {
    function reservedOf(address account) external view returns (uint256);

Function for query:

  • function reservedOf(address account) public view returns (uint256)
Supports BURNING

Supports burning with a Burn event and also reduces the TOTAL SUPPLY CAP LIMIT, by:

  • Transfer Voken2.0 to this contract address

  • Transfer Voken2.0 to address(0)

  • Call functions:

    • function burn(uint256 amount) public returns (bool)
    • function burnFrom(address account, uint256 amount) public returns (bool)
Supports SAFE-MODE

Transfers from non-whitelisted addresses are restricted when the amount number of Voken2.0 holders is insufficient to form a healthy ecological foundation. That is a SAFE-MODE for Voken2.0.

Function for query:

By transferring 1,001 Voken2.0 to a whitelisted address, will sign-up for whitelist and get 1 Voken2.0 refund as a success signal automatically.

Functions for query:

  • function whitelisted(address account) public view returns (bool)
