Many features on DappRadar are free to use, but premium services like Hot Contracts require you to have a PRO membership. This membership requires you to stake 30,000 RADAR tokens, which gives you:
🔥 Interest (15% APR) on your staked tokens
🎁 Free PRO Airdrops
🎉 Exclusive Quests
💥 And access to premium features, like the mentioned Hot Contracts.
And, when you don't feel like it anymore, you can unstake your RADAR tokens, claim your rewards and leave. But that's of course not what we hope.
