 ### Join as testnet validator
 
-* Import a key pair:
+* Create a validator from the onboarding app:
 
-  ```bash
-  KEY_NAME=alice
+  * Visit the [validator creation](https://loro-signup.laconic.com/validator) page
 
-  # Restore existing key with mnemonic seed phrase
-  # You will be prompted to enter mnemonic seed
-  laconic-so deployment --dir testnet-laconicd-deployment exec laconicd "laconicd keys add $KEY_NAME --recover"
+  * Select the Laconic account (same as the one used while onboarding) using which you wish to send the create validator request
 
-  # Query the keystore for your account's address
-  laconic-so deployment --dir testnet-laconicd-deployment exec laconicd "laconicd keys show $KEY_NAME -a"
-  ```
+    * This should display the details of your onboarded participant
 
-* Check balance for your account:
+    * You can proceed if the participant has `validator` role
 
-  ```bash
-  laconic-so deployment --dir testnet-laconicd-deployment exec laconicd "laconicd query bank balances <account-address>"
-  ```
+  * Enter your node's moniker (use the same one used while [configuring](#configuration) the `testnet-laconicd-deployment`)
 
-* Create required validator configuration:
+  * Fetch and enter your validator's pubkey:
 
-  ```bash
-  # Note:
-  # Edit the staking amount and other fields as required
-  # Replace <your-node-moniker> with your node's moniker in command below
+    ```bash
+    laconic-so deployment --dir testnet-laconicd-deployment exec laconicd "laconicd cometbft show-validator" | jq -r .key
+    ```
 
-  laconic-so deployment --dir testnet-laconicd-deployment exec laconicd 'cat <<EOF > my-validator.json

-  ```
+  * Send the transaction request to wallet
 
-* Create a validator:
+    * From wallet, approve and send transaction to stage1 laconicd chain
 
-  ```bash
-  laconic-so deployment --dir testnet-laconicd-deployment exec laconicd "laconicd tx staking create-validator my-validator.json \
-  --fees 500000alnt \
-  --chain-id=laconic_9000-1 \
