Transaction Requests

In order to execute a transaction, a request must be sent. A transaction requests will contain following information:

• Transaction fee

• Transaction memo

  • Transaction type (type of transaction is involved [e.g., transfer MXW, send message, etc.])
  • Transaction data or variables involved

• Transaction signature (done by the requester)

Any property which accepts a number may also be specified as a BigNumber or hex string. Any property may also be given as a Promise which resolves to the expected transaction type.

Transaction Receipts

After every transaction, a receipt that contains all every information regarding the transaction will be generated.

Transaction hash and block number are givenn to check the transaction in blockchain.

{

    hash: "0x30080e4120ee65abdd2f7f9ba3ef2b42c34fb3e03de676d2f116a3a44ce65b74",

    nonce: 265,             // the transaction sequence
    index: 0,               // the transaction index is always set to "0" in receipt

    // Transaction status
