// In order to run the sample you will need:
// 1.- Use the faucet to fund source address
// Faucet https://accounts.blockcypher.com/testnet-faucet?a=n3D2YXwvpoPg8FhcWpzJiS3SvKKGD8AXZ4
// 2.- Get unspent transaction outputs (UTXOs) and select one:
// https://api.blockcypher.com/v1/btc/test3/addrs/n3D2YXwvpoPg8FhcWpzJiS3SvKKGD8AXZ4?unspentOnly=true
// 3.- Get the hex tx for the selected UTXO:
// https://live.blockcypher.com/btc-testnet/tx/e7f034f4a56999d04d8a3a8f07dca10e87cd4a7fd2a779e9ecd41c57afec84f8/
// 4.- Copy Tx Hex and paste here:
