Wallets

    Create Wallet

>>> BCoinNode::createWallet('my_wallet', ['witness' => true]);
=> TPenaranda\BCoin\Models\Wallet {#3129
     +"network": "main",
     +"wid": 13201,
     +"watchOnly": false,
     +"accountDepth": 1,
     +"token": "b1cd7d340e397cb62a0484ca16d1dcc71c1406a9b437283280e9b3fdbcb96def",

       +"coin": 0,
       +"unconfirmed": 0,
       +"confirmed": 0,
     },
   }
>>>

    Get Wallet

>>> $wallet = BCoinNode::getWallet('my_other_wallet');
=> TPenaranda\BCoin\Models\Wallet {#3126
     +"network": "main",
     +"wid": 13202,
     +"watchOnly": false,
     +"accountDepth": 1,
     +"token": "20e2eb678be2679d6400aa733822b7eab68bca3148511403ba669ded830e7bcc",

     +"balance": {#3136
       +"tx": 0,
       +"coin": 0,
       +"unconfirmed": 0,
       +"confirmed": 0,
     },
   }
>>>

    Get Wallet nested address (only when ['witness' => true] opt was used for Wallet creation)

>>> $wallet->address;
=> "37vRA5NsGtnUoCtUtFAQmDWo6ucGi3J23C"
>>> BCoinNode::getWallet('my_other_wallet')->address;
=> "37vRA5NsGtnUoCtUtFAQmDWo6ucGi3J23C"
>>>

    Forget Wallet nested address. (This clears Cache but doesn't update the Wallet model. You needto refresh the
    Model in order to get the new address.)

=> "38EJvoLQmn7xG2iTeZ6ED6jrVLPND7Lo62"
