Lava Point is a private RPC platform where you can do transactions and earn points, while Rabby wallet is a DEX wallet like metamask, coin base,etc that is currently offering a point based airdrop program where you earn points for making transactions. So are you thinking what I am thinking?
First it is right to know that if you are uncomfortable with changing your crypto wallet RPC because of the risks that comes with RPC change, you should totally avoid doing this task, but if you don't mind, then proceed. First you need to get a Rabby wallet, it can be downloaded on chrome extension, to be safe I have gotten the legitimate link from the Rabby wallet website, but if you want to be sure, you can also get it yourself and verify. After downloading the Rabby chrome extension, you need to import your seed phrase Into the Rabby wallet, if you are uncomfortable importing your seed phrase to another wallet, you can ignore the task, don't do it.
After importing your wallet, go to the Rabby point section and input READTHISPLEASE as the code. Now you have registered on Rabby point, anytime you perform a transaction you will earn Rabby point. The next task is to do Lava Point, go to this Lava link, register and have an account.
