# Stake key registration The new stake key (of the hardware wallet) must be registered on the blockchain and delegated to the stake pool. This can also be done by connecting the hardware wallet to a wallet like Eternl, Yoroi, Adalite.io etc. and delegating from there. To do it in the command line, follow the instructions below. Save the following script as `hw-stake-registration.sh` in the `pool-scripts` folder and execute it to generate the certificate: ```bash #!/bin/bash source ./env cardano-cli stake-address registration-certificate \ --stake-verification-key-file ${NODE_HOME}/keys/hw-stake.vkey \ --out-file ${NODE_HOME}/pool-certificates/hw-stake-registration.cert ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
