✅ This guide assumes you generated your original
pool.certby following the Register Your Stake Pool guide.⚠️ If you’re changing your preview-pool-metadata.json, recalculate the metadata hash and upload the updated file before continuing. Follow steps listed in Register Your Stake Pool guide.
Step 1 - Edit the env file
Section titled “Step 1 - Edit the env file”Update the values in your env file with the updated information for your pool.
⚠️ On an air-gapped machine
sudo nano $HOME/dingo/pool-scripts/envSample env file:
PLEDGE=25000000000 # 25,000 ADACOST=170000000 # 170 ADAMARGIN=0.01 # 1 %
NET="--testnet-magic 2" #previewRELAY1_HOST=55.209.117.58RELAY1_PORT=6000RELAY2_HOST=55.23.123.206RELAY2_PORT=6000METADATA_URL=https://website.com/preview-pool-metadata.jsonMETADATA_HASH=$(cat $HOME/dingo/previewPoolMetaDataHash.txt)Step 2 - Execute the Script
Section titled “Step 2 - Execute the Script”The script must be executed in order to generate the new stake pool registration certificate, which will need to be submitted with a transaction.
cd $HOME/dingo/pool-scripts./pool-registration.shStep 3 - Copy pool.cert to your hot environment
Section titled “Step 3 - Copy pool.cert to your hot environment”Copy pool.cert to the ~/dingo directory on your hot environment (block producer or relay node).
Step 4 - Submit the Pool Certificate
Section titled “Step 4 - Submit the Pool Certificate”Build and sign the transaction to submit the updated pool.cert on-chain.
Step 4.1 - Query the current slot
Section titled “Step 4.1 - Query the current slot”currentSlot=$(cardano-cli conway query tip --testnet-magic 2 | jq -r '.slot')echo Current Slot: $currentSlotStep 4.2 - Build the Transaction
Section titled “Step 4.2 - Build the Transaction”cd ~/dingocardano-cli conway transaction build \ --tx-in $(cardano-cli query utxo --address $(cat payment.addr) --out-file /dev/stdout | jq -r 'keys[0]') \ --change-address $(cat payment.addr) \ --certificate-file pool.cert \ --invalid-hereafter $(( ${currentSlot} + 1000 )) \ --witness-override 2 \ --out-file tx.raw💡 Tip: OPTIONAL - To double-check that you have the correct values for your pool.cert run:
Step 4.3 - Sign the Transaction
Section titled “Step 4.3 - Sign the Transaction”Copy tx.raw to your cold environment in your ~dingo directory
⚠️ On an air-gapped machine
cd ~/dingocardano-cli conway transaction sign \--tx-body-file tx.raw \--signing-key-file payment.skey \--signing-key-file $HOME/dingo/cold-keys/node.skey \--out-file tx.signedStep 4.4 - Submit the Transaction
Section titled “Step 4.4 - Submit the Transaction”Copy tx.signed to the ~/dingo directory on your hot environment (block producer or relay node).
cd ~/dingocardano-cli conway transaction submit --tx-file tx.signedStep 5 - Verify the Registration
Section titled “Step 5 - Verify the Registration”Changes take effect in two epochs. After the next epoch transition, verify that your pool settings are correct.
Wait a few minutes for the transaction to reach the chain, then you can use your preferred Cardano explorer to see if transaction was successful like: https://cardanoscan.io/
