Stake key delegation

The stake key delegation can also be done by connecting the hardware wallet to a wallet like Eternl, Yoroi, etc. and delegating from there. To do it in the command line, follow the instructions below.
Save as and execute the following script, in order to create the certificate required to delegate the hardware wallet stake key to the stake pool:
source ./env
cardano-cli stake-address delegation-certificate \
--stake-verification-key-file ${NODE_HOME}/keys/hw-stake.vkey \
--cold-verification-key-file ${NODE_HOME}/pool-keys/cold.vkey \
--out-file ${NODE_HOME}/pool-certificates/hw-stake-delegation.cert
