Claiming Stake Pool Rewards

Let's walk through an example to claim your stake pools rewards.

Rewards are accumulated in the stake.addr address.

First, you need to ensure that your stake.addr is delegating to a representative.

Second, find the tip of the blockchain to set the invalid-hereafter parameter properly.

currentSlot=$(cardano-cli conway query tip --mainnet | jq -r '.slot')
echo Current Slot: $currentSlot

Set the amount to send in lovelaces. Remember 1 ADA = 1,000,000 lovelaces.

rewardBalance=$(cardano-cli conway 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 conway 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 conway transaction build-raw \
    ${tx_in} \
    --tx-out $(cat payment.addr)+$(( ${total_balance} + ${rewardBalance} )) \
    --invalid-hereafter $(( ${currentSlot} + 10000 )) \
    --fee 200000 \
    --withdrawal ${withdrawalString} \
    --out-file tx.tmp

Calculate the current minimum fee:

fee=$(cardano-cli conway 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 conway 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 conway 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 conway transaction submit \
    --tx-file tx.signed \
    --mainnet

Check if the funds arrived.

cardano-cli conway query utxo \
    --address ${destinationAddress} \
    --mainnet

You should see output similar to this showing your updated Lovelace balance with rewards.

                           TxHash                                 TxIx        Lovelace
