The ERC20 token is the most commonly used token standard on the [[Ethereum]] blockchain. As such, it is the most popular token for companies running an [[ICO]].

The ERC20 token required functions are:
* Get the total token supply:

<code>function totalSupply() public constant returns (uint);</code>

* Get the account balance of another account:

<code>function balanceOf(address tokenOwner) public constant returns (uint balance);</code>

* Returns the amount which the spender is still allowed to withdraw from the owner:

<code>function allowance(address tokenOwner, address spender) public constant returns (uint remaining);</code>

* Send amount of tokens to address:

<code>function transfer(address to, uint tokens) public returns (bool success);</code>

* Allow spender to withdraw from your account, multiple times, up to the amount written. If this function is called again it overwrites the current allowance with the value:

<code>function approve(address spender, uint tokens) public returns (bool success);</code>

* Send amount of tokens from one address to another address:

<code>function transferFrom(address from, address to, uint tokens) public returns (bool success);</code>

* Triggered when tokens are transferred

<code>event Transfer(address indexed from, address indexed to, uint tokens);</code>

* Triggered whenever approve is called:

<code>event Approval(address indexed tokenOwner, address indexed spender, uint tokens);</code>
}

Examples:
* [[QTUM]]
* [[EOS]]
* [[KredCoins]]
