z_shieldcoinbase - Zcash 5.5.0 RPC

z_shieldcoinbase "fromaddress" "tozaddress" ( fee ) ( limit ) ( memo ) ( privacyPolicy )

Shield transparent coinbase funds by sending to a shielded zaddr.  This is an asynchronous operation and utxos
selected for shielding will be locked.  If there is an error, they are unlocked.  The RPC call `listlockunspent`
can be used to return a list of locked utxos.  The number of coinbase utxos selected for shielding can be limited
by the caller. Any limit is constrained by the consensus rule defining a maximum
transaction size of 100000 bytes before Sapling, and 2000000 bytes once Sapling activates.

1. "fromaddress"         (string, required) The address is a taddr or "*" for all taddrs belonging to the wallet.
2. "toaddress"           (string, required) The address is a zaddr.
3. fee                   (numeric, optional, default=null) The fee amount in ZEC to attach to this transaction. The default behavior
                         is to use a fee calculated according to ZIP 317.
4. limit                 (numeric, optional, default=50) Limit on the maximum number of utxos to shield.  Set to 0 to use as many as will fit in the transaction.
5. "memo"                (string, optional) Encoded as hex. This will be stored in the memo field of the new note.
6. privacyPolicy         (string, optional, default="AllowRevealedSenders") Policy for what information leakage is acceptable.
                         This allows the same values as z_sendmany, but only "AllowRevealedSenders" and "AllowLinkingAccountAddresses"
                         are relevant.

  "remainingUTXOs": xxx    (numeric) Number of coinbase utxos still available for shielding.
  "remainingValue": xxx    (numeric) Value of coinbase utxos still available for shielding.
  "shieldingUTXOs": xxx    (numeric) Number of coinbase utxos being shielded.
  "shieldingValue": xxx    (numeric) Value of coinbase utxos being shielded.
  "opid": xxx          (string) An operationid to pass to z_getoperationstatus to get the result of the operation.
