Create TX Sample (without sending it)

This sample code demonstrate how you can create a new transaction, as documented here at: http://dev.blockcypher.com/#creating-transactions Destination address is a multisig address. API used: POST /v1/btc/main/txs/new

require __DIR__ . '/../bootstrap.php';

Create a new instance of TX object

$tx = new \BlockCypher\Api\TX();

partially-filled out TX request object.

To use BlockCypher’s two-endpoint transaction creation tool, first you need to provide the input address(es), output address, and value to transfer (in satoshis). This is provided in the form of a partially-filled out TX request object.
