Sending funds on testnet

Technical Support

I’ve mined quite a few blocks on testnet but it seems it’s not possible to send them, even though they’ve matured:

All transactions get rejected with orphan state (-1) in listtransactions

Mined coinbase must be spent to a z-addr. More specifically, any transaction that contains coinbase as an input must have no transparent outputs (excluding fees). This is enforced by consensus rules.

3

Hmm, that means any mined funds must be moved to a z address before they can be spent as usual? Is a z address a special generated address or just a mainnet address beginning with ‘z’?

specially generated

~/zcash/./src/zcash-cli zcrawkeygen
~/zcash/./src/zcash-cli zcrawjoinsplit “$(~/zcash/./src/zcash-cli createrawtransaction ‘[{“txid”:“TransparentAddieofBlock”,“vout”:0}]’ ‘{}’)” ‘{}’ “{"AnonAddressYouWantToSendTo”:1}" 1 0
~/zcash/./src/zcash-cli signrawtransaction “$RAWTXN_FROM_ZCRAWJOINSPLIT”
~/zcash/./src/zcash-cli sendrawtransaction “$RAWTXN_FROM_SIGNRAWTRANSACTION”

mined coin can not be used directly

6

A z-addr is a shielded address used for JoinSplits. You can generate one with z_getnewaddress.

Thanks guys, good I’m testing this all before mainnet launch.
