An accountant who turned cryptopreneur to pursue my interest in crypto and decentralized finance. Let me show you how to invest safely in the space with my experience over the years.

Klaytn is an EVM layer1 chain designed to be practical and reliable.

The network is a public blockchain that was created with total focus on metaverse, GameFi and creator economy.

It was launched in June 2019, and also established itself as the dominant blockchain platform in South Korea.

The Ethereum-compatible chain is now undergoing business expansion from its base in Singapore, headed by the Klaytn Foundation.

It uses the Istanbul Byzantine fault tolerant (IBFT) consensus algorithm based on PoS (i.e. Proof of Stake).

Although, Klaytn has a browser extension wallet called Kaikas, its features are similar to that of MetaMask.

MetaMask is mostly used as a wallet for Ethereum, but it’s also compatible with KLAY due to the identical address structures.

In this article, I will reveal steps on how you can connect Klaytn network to MetaMask wallet.

Let’s get started.

How to add Klaytn to MetaMask

To add KLAY to a Web3 crypto wallet, there are two different ways you can use to add Klaytn to your MetaMask account.

These way to safely add Klaytn (KLAY) to MetaMask are as follows:

  1. Manually adding Klaytn using RPC details
  2. Adding Klaytn through Chainlist platform.

However, I’ll walk you through all the processes having in mind that your MetaMask is installed as Chrome extension on your PC.

By the way, in all these steps below, am assuming that your MetaMask wallet account is already setup fully.

Otherwise, you should download MetaMask on your browser (e.g. Chrome), or mobile smartphone and set it up.

Adding Klaytn to MetaMask with RPC detail

Any network that you want to add to your MetaMask wallet requires that you to put in the network details such as the Chain ID, RPC URL etc.

To add the Klaytn network to your wallet, sign-in to your MetaMask account, then copy and paste the following details into the network settings.

Klaytn mainnet (Cypress) info:

Network Name: Klaytn Mainnet
Chain ID: 8217
Currency Symbol: KLAY
Block Explorer URL:

Klaytn testnet (Baobab) chain info:

Network Name: Klaytn Baobab
New RPC URL: (Default: http://localhost:8551)
Chain ID: 1001
Currency Symbol: KLAY
Block Explorer URL:

Once you add these details, you will be redirected to the MetaMask network screen.

You can then copy your wallet address and start transferring funds, but remember to only transfer the funds that the network supports.

Adding Klaytn to MetaMask using Chainlist

If the process above seem too technical, you can use these steps below to add Klaytn chain network to your MetaMask.

  1. Open your MetaMask wallet
  2. Go-to Chainlist platform
  3. Searck for ‘Klaytn’ network
  4. Click on ‘Connect Wallet’
  5. Now click on ‘Add to MetaMask’
  6. Click ‘Approve’ on the wallet popup
  7. Then switch network to Klaytn.

As soon as you’re through with this process, you will see that you can then use Klaytn chain to transfer KLAY token.

Final words

Adding Klaytn to MetaMask is a manual process, and when done right, you can send or receive KLAY crypto.

If you want to switch back to Ethereum Mainnet, you can click the network drop-down.

Do not that protecting your cryptocurrency wallet is very essential to making sure you don’t loose your fund.
