Can anyone call the Burn function in ERC20PresetMinterPauser?

Support Contracts

Can anyone who owns the token call the burn function or can only the deployer/owner of the contract call the burn function? (ERC20PresetMinterPauser contract).

I want to effectively reduce the Total Supply through the burn function.

The ERC20PresetMinterPauser contract inherits from the ERC20Burnable contract which exposes the burn() method that can be called by anyone to burn their own tokens:

function burn(uint256 amount) public virtual {
    _burn(_msgSender(), amount); // _msgSender() here equals to the caller
}

Short answer is then that anybody can call burn(), but cannot burn other people’s tokens. When this happens, the totalSupply is reduced.
