sendmany - Zcash 1.1.1 RPC

sendmany "fromaccount" {"address":amount,...} ( minconf "comment" ["address",...] )

Send multiple times. Amounts are double-precision floating point numbers.

Arguments:
1. "fromaccount"         (string, required) MUST be set to the empty string "" to represent the default account. Passing any other string will result in an error.
2. "amounts"             (string, required) A json object with addresses and amounts
    {
      "address":amount   (numeric) The Zcash address is the key, the numeric amount in ZEC is the value
      ,...
    }
3. minconf                 (numeric, optional, default=1) Only use the balance confirmed at least this many times.
4. "comment"             (string, optional) A comment
5. subtractfeefromamount   (string, optional) A json array with addresses.
                           The fee will be equally deducted from the amount of each selected address.
                           Those recipients will receive less Zcash than you enter in their corresponding amount field.
                           If no addresses are specified here, the sender pays the fee.
    [
      "address"            (string) Subtract fee from this address
      ,...
    ]

Result:
"transactionid"          (string) The transaction id for the send. Only 1 transaction is created regardless of 
                                    the number of addresses.

Examples:

Send two amounts to two different addresses:
> zcash-cli sendmany "" "{\"t14oHp2v54vfmdgQ3v3SNuQga8JKHTNi2a1\":0.01,\"t1353tsE8YMTA4EuV7dgUXGjNFf9KpVvKHz\":0.02}"

Send two amounts to two different addresses setting the confirmation and comment:
> zcash-cli sendmany "" "{\"t14oHp2v54vfmdgQ3v3SNuQga8JKHTNi2a1\":0.01,\"t1353tsE8YMTA4EuV7dgUXGjNFf9KpVvKHz\":0.02}" 6 "testing"
