Keys and Passwords

The next step is to set up a strong password. Crypto thefts are a daily reality so pick a really strong password. Mark it down carefully in a safe place. You can change the password anytime.

In the following step, the wallet generates the Secret Recovery Phrase. It is a 12-word phrase that is a master password to your wallet. Careful, if you lose it, your money is lost. Never share the phrase with anyone and carefully store it. Some people carve it to a metal bar and keep it in a vault.

Setting up the wallet

Is only the first step

Metamask makes sure that you remember the phrase and ask you to write it down on the next page. Then it congratulates you because your wallet is set up.

Hurray, you are halfway through. Now you have to set up the wallet account for each currency. Chumbi Valley is using two cryptocurrency networks - Polygon for NTFs (Chumbi creatures) and Binance Smart Chain for CHMB currency.

Luckily, the matamask wallet address is the same for every crypto currency network you use.
