Prerequisites
Both a payment and a stake key pair. Payment key should contain some ADA.
Registering Your Stake Address
Create a certificate, stake.cert, using the stake.vkey
cardano-cli stake-address registration-certificate \
--stake-verification-key-file stake.vkey \
--out-file stake.cert
You need to find the slot tip of the blockchain.
currentSlot=$(cardano-cli query tip --mainnet | jq -r '.slot')
echo Current Slot: $currentSlot
Find your balance and UTXOs.
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: ${txcnt}
Find the stakeAddressDeposit value.
stakeAddressDeposit=$(cat $NODE_HOME/params.json | jq -r '.stakeAddressDeposit')
echo stakeAddressDeposit : $stakeAddressDeposit
Registration of a stake address certificate (stakeAddressDeposit) costs 2000000 lovelace.
Run the build-raw transaction command
The invalid-hereafter value must be greater than the current tip. In this example, we use current slot + 10000.
cardano-cli transaction build-raw \
${tx_in} \
--tx-out $(cat payment.addr)+0 \
--invalid-hereafter $(( ${currentSlot} + 10000)) \
--fee 0 \
--out-file tx.tmp \
--certificate stake.cert
Calculate the current minimum fee:
fee=$(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: $fee
Ensure your balance is greater than cost of fee + stakeAddressDeposit or this will not work.
Calculate your change output.
txOut=$((${total_balance}-${stakeAddressDeposit}-${fee}))
echo Change Output: ${txOut}
Build your transaction which will register your stake address.
cardano-cli transaction build-raw \
${tx_in} \
--tx-out $(cat payment.addr)+${txOut} \
--invalid-hereafter $(( ${currentSlot} + 10000)) \
--fee ${fee} \
--certificate-file stake.cert \
--out-file tx.raw
Sign the transaction with both the payment and stake secret keys.
cardano-cli transaction sign \
--tx-body-file tx.raw \
--signing-key-file payment.skey \
--signing-key-file stake.skey \
--mainnet \
--out-file tx.signed
Send the signed transaction.
cardano-cli transaction submit \
--tx-file tx.signed \
--mainnet
Given its stake pool verification key file node.vkey , from your stakepool should have generated (and published) a stake pool ID:
cardano-cli stake-pool id \
--cold-verification-key-file node.vkey \
--output-format 'hex'
Given the stake pool ID from your stakepool, run the following:
cardano-cli stake-address delegation-certificate \
--stake-verification-key-file stake.vkey \
--stake-pool-id <stake pool ID> \
--out-file deleg.cert
You need to find the tip of the blockchain to set the ttl parameter properly.
currentSlot=$(cardano-cli query tip --mainnet | jq -r '.slot')
echo Current Slot: $currentSlot
Find your balance and UTXOs.
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}
Run the build-raw transaction command.
cardano-cli transaction build-raw \
${tx_in} \
--tx-out $(cat payment.addr)+${total_balance} \
--invalid-hereafter $(( ${currentSlot} + 10000)) \
--fee 0 \
--certificate-file deleg.cert \
--out-file tx.tmp
Calculate the minimum fee:
fee=$(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}))
echo txOut: ${txOut}
Build the transaction.
cardano-cli transaction build-raw \
${tx_in} \
--tx-out $(cat payment.addr)+${txOut} \
--invalid-hereafter $(( ${currentSlot} + 10000)) \
--fee ${fee} \
--certificate-file deleg.cert \
--out-file tx.raw
Sign the transaction.
cardano-cli transaction sign \
--tx-body-file tx.raw \
--signing-key-file payment.skey \
--signing-key-file stake.skey \
--mainnet \
--out-file tx.signed
Send the transaction.
cardano-cli transaction submit \
--tx-file tx.signed \
--mainnet
Congratulations! Your ADA is now successfully delegated to your chosen stakepool.
