Connecting MetaMask
Note: MetaMask is mostly used as a wallet for Ethereum, but it is also compatible with Klaytn due to the identical address structures. Klaytn also has a browser extension wallet called Kaikas, so it basically provides the same features as MetaMask, except for Remix.
Step 1. Install MetaMask
We will be using Chrome browser in this example. (Install Chrome)
Add MetaMask Extension to Chrome.
Note: You may need additional installations if you are using another browser.
You can start MetaMask by clicking on the icon in the upper right-hand corner of your chrome browser.
Step 2. Generate a MetaMask Wallet
Create a Wallet
Click on [Create a Wallet].
Set a password.
You will be given a 12 word seed phrase; back it up somewhere secure.
Note: You can only restore your wallet with the seed phrase. Sharing your seed phrase with others may result in losing all of your funds. Therefore, it is recommended that you either write it down manually or store it in an offline device.
