function, constant

`allowance` `dd62ed3e`

Function to check the amount of tokens that an owner allowed to a spender.

inputs	0	address	`_owner`	address The address which owns the funds.
inputs	inputs	1	address	`_spender`	address The address which will spend the funds.
outputs	0	uint256

function

`approve` `095ea7b3`

Approve the passed address to spend the specified amount of tokens on behalf of msg.sender. * Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729

inputs	0	address	`_spender`	The address which will spend the funds.
inputs	inputs	1	uint256	`_value`	The amount of tokens to be spent.

function, constant

`balanceOf` `70a08231`

Gets the balance of the specified address.

inputs	0	address	`_owner`	The address to query the the balance of.
outputs	0	uint256	`balance`

function, constant

`canRedeemUTXO` `06f84701`

Convenience helper function to check if a UTXO can be redeemed

inputs	0	bytes32	`txid`	Transaction hash
	inputs	1	bytes20	`originalAddress`	Raw Bitcoin address (no base58-check encoding)
	inputs	2	uint8	`outputIndex`	Output index of UTXO
	inputs	3	uint256	`satoshis`	Amount of UTXO in satoshis
	inputs	4	bytes	`proof`	Merkle tree proof
outputs	0	bool

function, constant

`canRedeemUTXOHash` `a2d0f942`

Verify that a UTXO with the specified Merkle leaf hash can be redeemed

inputs	0	bytes32	`merkleLeafHash`	Merkle tree hash of the UTXO to be checked
inputs	inputs	1	bytes	`proof`	Merkle tree proof
outputs	0	bool

function

`decreaseApproval` `66188463`

inputs	0	address	`_spender`
inputs	inputs	1	uint256	`_subtractedValue`

function, constant

`ecdsaVerify` `ce267b55`

Validate that the hash of a provided address was signed by the ECDSA public key associated with the specified Ethereum address

inputs	0	address	`addr`	Address signed

outputs	0	bool

function

`increaseApproval` `d73dd623`

approve should be called when allowed[_spender] == 0. To increment allowed value is better to use this function to avoid 2 calls (and wait until the first transaction is mined) From MonolithDAO Token.sol
