When you sign up for a Cake DeFi account and make your first deposit of $50 or more in value (with any coin), you will receive a bonus of $20 worth of DFI. This bonus will be locked up for 180 days in the Freezer and automatically yields staking returns during this time.
If you use a referral code, both you and your referrer will receive an extra $10 worth of DFI, which will also be locked and staked in the Confectionery program.
