Important: Use the Official RPC Only

Before proceeding, please note:

If you’ve previously added Klaytn using a third-party RPC provider like Ozys, you must remove it first. Continuing with unofficial endpoints may result in a Chain ID conflict or transaction failures due to API rate limits.

We strongly recommend using the official public RPC URL provided below to ensure stability, reliability, and full compatibility with the latest Klaytn mainnet updates.

Frequently Asked Questions (FAQ)

Q1: Will I lose my KLAY tokens when re-adding the network?

No. Changing or re-adding a network in MetaMask does not affect your token balance. Your funds remain safe in your wallet as long as you retain access to your seed phrase.

Q2: What if I get a "Chain ID already exists" error?

This means another network with Chain ID 8217 is already configured — likely an outdated or unofficial version. Delete any existing Klaytn entries under Settings > Networks, then re-add using the official RPC URL.

Q3: Can I use MetaMask with Klaytn dApps like Ground X or Klip?

Yes! Once connected, you can visit Klaytn-powered platforms such as Kaikas, Dunamu, and various NFT marketplaces. Just make sure your wallet is set to Klaytn Mainnet before interacting.

Q4: Is the public RPC reliable for daily use?

The official public endpoint (public-en-cypress.klaytn.net) is maintained by the Klaytn Foundation and suitable for most users. For developers requiring higher request limits, consider setting up a dedicated node or using a private RPC service.

Q5: How do I switch back to Ethereum or another network?

Simply click or tap the network selector and choose your desired chain (e.g., Ethereum, BSC, etc.). MetaMask remembers all added networks, so switching takes seconds.
