2: Stake KSM to Cloud with Polkadot.js

1. Bond your KSM and nominate Coinbase Cloud's validators

  1. Go to the Polkadot UI.

  2. Click STAKING under NETWORK in the top navigation.

  3. Select the ACCOUNT ACTIONS in the Staking navigation at the top.

Double check that your controller has the nominal funds (6-11 KSM) it needs for the “existential deposit” and to pay for transaction fees.

  2. Select your preferred payment destination: Select _Stash account (increase the amount at stake) to compound your rewards on your Stash account (most common), or Select _Stash account (do not increase the amount at stake) to leave your rewards un-bonded and spendable in your Stash account.

  3. Click NEXT.

  4. Disable autoselect to enable searching for nominators.

  5. Search for and select the Coinbase Cloud validators:
