You can send crypto tokens to your wallet from an existing wallet or an exchange account. For a list of ERC-20 tokens that are supported by the app please see https://support.monolith.xyz/hc/en-us/articles/360002236637-What-tokens-are-available-on-the-wallet-.
To add tokens, you will need your wallet address (a long alphanumeric code also known as a \"Public Key\") which can be found clicking on the '+' icon in the center at the bottom of the app, then selecting 'Receive'. You can also scan the QR code found here.
Once sent, it should take 20-60 seconds for you to receive the tokens in your Contract Wallet.
