##REFERENCES:

–tx-in is your wallet address you are going to pay for the transaction from. You need to control this address key to sign the transaction.

–change-address is your wallet address you want your change to go to.

Steps

  1. Find an available poll
    Available polls are listed in the table above. Alternatively, you can use the getPoll.sh script to look for specific polls submitted on-chain.

  1. Create a poll answer
    Use the cardano-cli governance answer-poll command to create an answer.

  2. Build a transaction with metadata
    Build a transaction using the poll answer as metadata. You’ll also need to indicate your pool id as an extra required signatory.

  3. Sign the transaction
    The transaction must be signed using your cold key.

  4. Submit the transaction
    Finally, submit the transaction to the network.

Where did you get that poll.json? There is no such file anywhere in that linked github repo in first step

OK, I found it, but how do I sign this TX using HW wallet? When I use cardano-hw-cli with this BabbageEra TX body I get:

Error: Invalid file contents of tx-body-file

it seems it’s not necessary to witness this TX with pool owner wallets, just node skey, so I got it to work.
