1.2) Click "Download Now" and click "Install MetaMask for Chrome" (or choose iOS / Android for mobile version).

2) Using MetaMask
One of the first tasks you will want to do on MetaMask is to install a wallet (or "vault" as MetaMask calls it) to hold your Cryptocurrencies. To do this, follow the instructions below,
2.1) Click on the MetaMask logo in the upper right corner of the browser.
2.2) Read and agree to the terms and conditions. You may have to agree to 2-3 pages worth of terms.
2.3) Enter a password and click "Create" to create your wallet.
2.4) You will see a set of 12 "seed words" for your vault. Click "Save Seed Words as File" and copy the "MetaMask Seed Words" file that is downloaded to a safe place. You will need them to access your vault.
2.5) Click "I've copied it somewhere safe" once your seed words file has been secured. You will be taken into your MetaMask Wallet!
You are now in the Ethereum Mainnet Network.
To be able to trade StakeMars ($STM), you will have to connect your MetaMask Wallet to Binance Smart Chain and Polygon Chain.
