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

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

  • In the value bonded field, input the amount of KSM you’d like to bond. If you’d like to bond all of your KSM, pleaseleave 5-10 KSM in your stash account for transaction fees
  • 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
  • Click NEXT
  • Disable autoselect to enable searching for nominators

Please enter each of the Coinbase Cloud validator addresses from the list above when staking.
Selecting all validators from this list indicates your willingness to support any of them, and the protocol will then automatically allocate your stake to a subset of the validators from your nominated list that have been selected to participate and earn rewards each era. As such, selecting all validators increases your opportunities to earn rewards. Learn more in our Kusama FAQs.

  • Enter your stash password in the pop up window
  • Click Sign the transaction
  • Wait for the Transaction Success banner to pop up. This process can take a little while if the network is behind.
