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.

Step 3. Connect to Klaytn Cypress Network (Mainnet)

Here's a simple way. Connect your wallet to the Klaytn Cypress Network (Mainnet).

Step 4. Send KLAY

Note: The following steps require KLAY.

• Click [Send] on the main page and enter the recipient address and the amount of KLAY.

Send KLAY 1

NOTE: Sending KLAY requires a transaction, for which you need KLAY.

• Since Klaytn v1.9.0, a dynamic gas fee mechanism has replaced the existing fixed price policy.

• So you don't have to set the fixed gas fee manually.

• Check the amount to send and the transaction fee and click [Confirm] to complete the KLAY transfer, after which you will be redirected to the main page.

• Click [Activity] on the main page to confirm the transaction history.

Send KLAY 2

Connect to Klaytn Baobab Network (Testnet)
