Kind: instance method of Create

create.createAndSignOrder(options)

Kind: instance method of Create

| Param | Type | Description | | ------- | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | options | object | object with the following properties: makerAssetAddress: either ("WETH/DAI/ZRX") or a full 42 char hex address takerAssetAddress: either ("WETH/DAI/ZRX") or a full 42 char hex address makerAssetAmount: units are wei, value can be string/number or BigNumber takerAssetAmount: units are wei, value can be string/number or BigNumber orderDuration: the number of seconds the order should be valid for makerAddress: can be provided to override coinbase, but shouldn't |

Example

// create an order for 0.5 WETH <> 80 custom token, valid for 10 minutes
let order = await create.createAndSignOrder({
    makerAssetAddress: "WETH",
    takerAssetAddress: "0x9f8f72aa9304c8b593d555f12ef6589cc3a579a2",
    makerAssetAmount: create.convertToWei("0.5"),
    takerAssetAmount: create.convertToWei("80"),
    orderDuration: 600,
});

create.signAndPost(signedZeroExOrder)

Kind: instance method of Create
Todo:: - undo split-network ugly-ness

don't pull makerArguments from subcontract if provided
ability to use direct kosu.js to sign

| Param | Type | Description | | ----------------- | ------------------- | -------------------------------------------------------- | | signedZeroExOrder | object | as outputted from createAndSignOrder |

create.convertToWei(etherAmount) ⇒ Promise.<string>

Kind: instance method of Create
Returns: Promise.<string> - the same amount in wei

| Param | Type | Description | | ----------- | --------------------------------------------- | ----------------------------------------------- | | etherAmount | string | BigNumber | a number of tokens in full units (ether) |

Example

// convert 100 tokens (as entered by user) to wei
create.convertToWei("100"); // > "100000000000000000000" (BigNumber)
create.convertToWei(100); // > "100000000000000000000" (BigNumber)

create.convertFromWei(weiAmount) ⇒ Promise.<string>

Kind: instance method of Create
Returns: Promise.<string> - the same amount in ether

| Param | Type | Description | | --------- | --------------------------------------------- | ------------------------------------------------- | | weiAmount | string | BigNumber | a number of tokens in smallest units (wei) |

Example

// convert 100 tokens (as received as balance or allowance) to tokens
create.convertToWei("100000000000000000000"); // > "100" (BigNumber)
create.convertToWei(100000000000000000000); // > "100" (BigNumber)

create.isValidAddress(address) ⇒ boolean

Kind: instance method of Create
Returns: boolean - true if valid Ethereum address, otherwise false

| Param | Type | Description | | ------- | ------------------- | ------------------------------------------------------ | | address | string | a string to be validated as an Ethereum address |

Example

create.isValidAddress("0x4f833a24e1f95d70f028921e27040ca56e09ab0b"); // > true
create.isValidAddress("4f833a24e1f95d70f028921e27040ca56e09ab0b"); // > false
create.isValidAddress("0x4f833a24e1f95d70f028921e27040ca56e09ab0"); // > false

create.userHasBond(userAddress) ⇒ Promise.<boolean>

Kind: instance method of Create
Returns: Promise.<boolean> - true if user has active bond, false otherwise

| Param | Type | Description | | ----------- | ------------------- | ---------------------------------------------------------- | | userAddress | string | can be provided to override coinbase, but shouldn't |

create.awaitTransactionSuccessOrThrow(txID) ⇒

Kind: instance method of Create
Returns: the full decoded transaction receipt (usually will not need)

| Param | Type | Description | | ----- | ------------------- | ----------------------------------------------------- | | txID | string | 32 byte (64-char) 0x-prefixed transaction hash |

Example

const txId = await create.setProxyAllowanceWeth();

// wait for the transaction to be mined, show loading icon, etc.
await create.awaitTransactionSuccessOrThrow(txId);

create.getUserWethBalance(userAddress) ⇒ Promise.<BigNumber>
