Token

Methods

totalSupply

function totalSupply() constant returns (uint256 supply)

Get the total coin supply

balanceOf

function balanceOf(address _address) constant returns (uint256 balance)

Get the account balance of another account with address _address

transfer

function transfer(address _to, uint256 _value) returns (bool _success)

Send _value amount of coins to address _to

transferFrom

function transferFrom(address _from, address _to, uint256 _value) returns (bool success)

Send _value amount of coins from address _from to address _to

The transferFrom method is used for a "direct debit" workflow, allowing contracts to send coins on your behalf, for example to "deposit" to a contract address and/or to charge fees in sub-currencies; the command should fail unless the _from account has deliberately authorized the sender of the message via some mechanism; we propose these standardized APIs for approval:

approve

function approve(address _address) returns (bool success)

Allow _address to direct debit from your account with full custody. Only implement if absolutely required and use carefully. See approveOnce below for a more limited method.

unapprove

function unapprove(address _address) returns (bool success)

Unapprove address _address to direct debit from your account if it was previously approved. Must reset both one-time and full custody approvals.

isApprovedFor

function isApprovedFor(address _target, address _proxy) constant returns (bool success)

Returns 1 if _proxy is allowed to direct debit from _target

approveOnce

function approveOnce(address _address, uint256 _maxValue) returns (bool success)

Makes a one-time approval for _address to send a maximum amount of currency equal to _maxValue

isApprovedOnceFor

function isApprovedOnceFor(address _target, address _proxy) returns (uint256 maxValue)

Returns _maxValue if _proxy is allowed to direct debit the returned maxValue from address _target only once. The approval must be reset on any transfer by _proxy of _maxValue or less.

Events

Transfer

event Transfer(address indexed _from, address indexed _to, uint256 _value)

Triggered when tokens are transferred.

AddressApproval

event AddressApproval(address indexed _address, address indexed _proxy, bool _result)

Triggered when an _address approves _proxy to direct debit from their account.

AddressApprovalOnce

event AddressApprovalOnce(address indexed _address, address indexed _proxy, uint256 _value)

Triggered when an _address approves _proxy to direct debit from their account only once for a maximum of _value
