| ### `new Transaction([data])` | ||
| Creates a new transaction object | ||
| - `data` - a transaction can be initiailized with either a `buffer` containing the RLP serialized transaction or an `array` of buffers relating to each of the tx Properties, listed in order below. For example. | ||
| ```javascript | ||
| var rawTx = { | ||
| nonce: '00', | ||
| gasPrice: '09184e72a000', | ||
| gasLimit: '2710', | ||
| to: '0000000000000000000000000000000000000000', | ||
| value: '00', | ||
| data: '7f7465737432000000000000000000000000000000000000000000000000000000600057', | ||
| v: '1c', | ||
| r: '5e1d3a76fbf824220eafc8c79ad578ad2b67d01b0c2425eb1f1347e8f50882ab', | ||
| s '5bd428537f05f9830e93792f90ea6a3e2d1ee84952dd96edbae9f658f831ab13' | ||
| }; | ||
| var tx = new Transaction(rawTx); | ||
| ``` | ||
| Or lastly an `Object` containing the Properties of the transaction like in the [Usage](#usage) example | ||
| For `Object` and `Arrays` each of the elements can either be a `Buffer`, a hex-prefixed (0x) `String` , `Number`, or an object with a `toBuffer` method such as `Bignum` | ||
| ### `transaction` Properties | ||
| - `raw` - The raw rlp decoded transaction. | ||
| - `nonce` | ||
| - `to` - the to address | ||
| - `value` - the amount of ether sent | ||
| - `data` - this will contain the `data` of the message or the `init` of a contract. | ||
| - `v` - EC signature parameter | ||
| - `r` - EC signature parameter | ||
| - `s` - EC recovery ID | ||
| -------------------------------------------------------- | ||
| ### `Transaction` Methods | ||
| #### `transaction.serialize()` | ||
| Returns the RLP serialization of the transaction | ||
| **Return:** 32 Byte `Buffer` | ||
| -------------------------------------------------------- | ||
| #### `transaction.hash([signature])` | ||
| Returns the SHA3-256 hash of the rlp transaction | ||
| **Parameters** | ||
| - `signature` - a `Boolean` determining if to include the signature components of the transaction. Defaults to true. | ||
| **Return:** 32 Byte `Buffer` | ||
| -------------------------------------------------------- | ||
| #### `transaction.sign(privateKey)` | ||
| Signs the transaction with the given privateKey. | ||
| **Parameters** | ||
| - `privateKey` - a 32 Byte `Buffer` | ||
| -------------------------------------------------------- | ||
| #### `transaction.getSenderAddress()` | ||
| Returns the senders address | ||
| **Return:** 20 Byte `Buffer` | ||
| -------------------------------------------------------- | ||
| #### `transaction.getSenderPublicKey()` | ||
| returns the public key of the sender | ||
| **Return:** `Buffer` | ||
| -------------------------------------------------------- | ||
| #### `transaction.validate()` | ||
| Determines if the transaction is schematicly valid by checking its signature and gasCost. | ||
| **Return:** `Boolean` | ||
| -------------------------------------------------------- | ||
| #### `transaction.validateSignature()` | ||
| Determines if the signature is valid | ||
| **Return:** `Boolean` | ||
| -------------------------------------------------------- | ||
| #### `transaction.getDataFee()` | ||
| Returns the amount of gas to be paid for the data in this transaction | ||
| **Return:** `bn.js` | ||
| -------------------------------------------------------- | ||
| #### `transaction.getBaseFee()` | ||
| Returns the minimum amount of gas the tx must have (DataFee + TxFee) | ||
| **Return:** `bn.js` | ||
| -------------------------------------------------------- | ||
| #### `transaction.getUpfrontCost()` | ||
| The total amount needed in the account of the sender for the transaction to be valid | ||
| **Return:** `bn.js` | ||
| -------------------------------------------------------- | ||
| #### `transaction.toJSON([object])` | ||
| Returns transaction as JSON | ||
| **Parameters** | ||
| - `object` - a `Boolean` that defaults to false. If `object` is true then this will return an object else it will return an `array` | ||
| **Return:** `Object` or `Array` | ||
