To start the download go to their website rabby.io and select the mobile option. If you do it from the PC, passing the mouse over the preferred option, it shows you the QR that you can scan with your smartphone to download.
Login to the wallet and it will give you several options to add an address (address or account).
For this section on mobile wallets we will discuss only the first 2. Although you can use Rabby to connect some hardware wallets, other mobile wallets like MetaMask or Trust, or other alternatives.
Create new address:
Add from Current Seed Phrase: in this option, you can add an account using the same seed phrase you already have, or should, written down on paper and in a safe place.
Create New Seed Phrase: gives you a new set of seed phrase words.
Import an address:
Import Seed Phrase: allows you to import an account that you already have using the seed phrase. Rabby may use another Derivation Path, so the imported address will be different from the one of the original wallet.
Import Private Key: this gives you the possibility to copy the private key from another wallet and import it into Rabby. This way you use the same Derivation Path and therefore you get the same address as in the original account.
The Import a Private Key option is the one to use if, for example, you have MOC tokens in stake.
Rabby integrates Rootstock so you will see your tokens on the main screen.
If you want to use the Money On Chain protocol you will have to do it through the integrated browser of the wallet by clicking on the Dapps button below.
In Advanced Settings, you can configure the Gas Limit.
Additionally, immediately below, the Gas Price appears, which is also configurable.
It offers the following options: Normal, Fast, Instant, and Custom (for those who wish to customize this value).
To check the Gas Price, press the drop-down button on the right and select the option you think is appropriate.
