Once you have migrated your coreDAO vouchers to coreDAO tokens, you can stake them on the website http://corefinance.eth/.
When you connect your wallet, your coreDAO balance is displayed in the bottom right corner of the Summary Tab. Staking requires two separate transactions, approving coreDAO, and staking coreDAO.
1. Approving coreDAO for staking
Once approved, press Stake & Approve the amount.
