Let's walk through an example to claim your stake pools rewards.
Rewards are accumulated in the stake.addr address.
First, find the tip of the blockchain to set the invalid-hereafter parameter properly.
currentSlot=$(cardano-cli query tip --mainnet | jq -r '.slot')
echo Current Slot: $currentSlot
rewardBalance=$(cardano-cli query stake-address-info \
--mainnet \
--address $(cat stake.addr) | jq -r ".[0].rewardAccountBalance")
echo rewardBalance: $rewardBalance
Set the destination address which is where you're moving your reward to. This address must have a positive balance to pay for transaction fees.
destinationAddress=$(cat payment.addr)
echo destinationAddress: $destinationAddress
Find your payment.addr balance, utxos and build the withdrawal string.
cardano-cli query utxo \
--address $(cat payment.addr) \
--mainnet > fullUtxo.out
tail -n +3 fullUtxo.out | sort -k3 -nr > balance.out
cat balance.out
tx_in=""
total_balance=0
while read -r utxo; do
type=$(awk '{ print $6 }' <<< "${utxo}")
if [[ ${type} == 'TxOutDatumNone' ]]
then
in_addr=$(awk '{ print $1 }' <<< "${utxo}")
idx=$(awk '{ print $2 }' <<< "${utxo}")
utxo_balance=$(awk '{ print $3 }' <<< "${utxo}")
total_balance=$((${total_balance}+${utxo_balance}))
echo TxHash: ${in_addr}#${idx}
echo ADA: ${utxo_balance}
tx_in="${tx_in} --tx-in ${in_addr}#${idx}"
fi
done < balance.out
txcnt=$(cat balance.out | wc -l)
echo Total available ADA balance: ${total_balance}
echo Number of UTXOs: ${txcnt}
withdrawalString="$(cat stake.addr)+${rewardBalance}"
Run the build-raw transaction command.
cardano-cli transaction build-raw \
${tx_in} \
--tx-out $(cat payment.addr)+0 \
--invalid-hereafter $(( ${currentSlot} + 10000)) \
--fee 0 \
--withdrawal ${withdrawalString} \
--out-file tx.tmp
Calculate the current minimum fee:
fee=$(cardano-cli transaction calculate-min-fee \
--tx-body-file tx.tmp \
--tx-in-count ${txcnt} \
--tx-out-count 1 \
--mainnet \
--witness-count 2 \
--byron-witness-count 0 \
--protocol-params-file params.json | awk '{ print $1 }')
echo fee: $fee
Calculate your change output.
txOut=$((${total_balance}-${fee}+${rewardBalance}))
echo Change Output: ${txOut}
Build your transaction.
cardano-cli transaction build-raw \
${tx_in} \
--tx-out $(cat payment.addr)+${txOut} \
--invalid-hereafter $(( ${currentSlot} + 10000)) \
--fee ${fee} \
--withdrawal ${withdrawalString} \
--out-file tx.raw
Copy tx.raw to your cold environment.
Sign the transaction with both the payment and stake secret keys.
cardano-cli transaction sign \
--tx-body-file tx.raw \
--signing-key-file payment.skey \
--signing-key-file stake.skey \
--mainnet \
--out-file tx.signed
Copy tx.signed to your hot environment.
Send the signed transaction.
cardano-cli transaction submit \
--tx-file tx.signed \
--mainnet
Check if the funds arrived.
cardano-cli query utxo \
--address ${destinationAddress} \
--mainnet
You should see output similar to this showing your updated Lovelace balance with rewards.
