How to add ZetaChain to MetaMask? (Mainnet settings)

Adding ZetaChain Mainnet to MetaMask

1. Open MetaMask and ensure you are using the latest version of the extension or mobile app.

2. Click on the network selector dropdown located in the top-left corner, usually showing “Ethereum Mainnet” or another active chain.
3. Scroll down and select “Custom RPC” from the list of available networks.
4. Enter the following parameters for ZetaChain Mainnet:Network Name: ZetaChain MainnetRPC URL: https://rpc.zetachain.com/Chain ID: 7000Currency Symbol: ZETABlock Explorer URL: https://explorer.zetachain.com/
5. Confirm and save the configuration. MetaMask will validate the connection and switch to ZetaChain Mainnet.

Verifying Connection Stability

1. After saving, check whether the network name appears correctly in the top bar—“ZetaChain Mainnet” should be visible.

2. Visit https://explorer.zetachain.com/ and compare recent block numbers with those shown in MetaMask’s activity feed.
3. Initiate a small native ZETA transfer between two test wallets to confirm transaction broadcasting and confirmation behavior.
4. Observe gas estimation values—ZetaChain uses EVM-compatible fee mechanics but calculates fees in ZETA rather than ETH.
5. Ensure that contract interactions with cross-chain bridges or omnichain smart contracts resolve without “invalid bytecode” or “network mismatch” errors.

Handling Common Configuration Errors

1. If MetaMask displays “Failed to fetch chain ID”, verify that the RPC endpoint responds by pasting https://rpc.zetachain.com/ into a browser and checking for JSON-RPC error responses.

2. When encountering “Invalid Chain ID”, double-check that the value entered is exactly 7000, not “7000” with extra spaces or quotation marks.
3. A “Network not supported” message may appear if MetaMask version is outdated—update to v11.12.0 or higher.
4. If token balances do not load after adding the network, manually add ZETA as a custom token using its contract address: 0x5F0e59a4387B3D6C92A5c213d926C77b38f28841.
5. Cross-chain dApp interfaces may require explicit network switching—some frontends auto-detect but others demand manual selection via wallet connect prompts.

Security Considerations for Omnichain Interaction

1. Never input seed phrases or private keys on third-party sites claiming to “add ZetaChain automatically”.

2. Confirm that all RPC endpoints used are official—unverified mirrors may intercept signing requests or inject malicious payloads.
3. Review permissions when connecting dApps: ZetaChain supports omnichain message passing, so some applications request access to multiple chains simultaneously.
4. Monitor pending transactions closely—ZetaChain’s cross-chain finality model introduces variable confirmation windows depending on source chain consensus.
5. Avoid reusing Ethereum-based wallet addresses across unrelated omnichain environments unless explicitly designed for shared key derivation.

Frequently Asked Questions

Q: Can I use the same MetaMask wallet address on ZetaChain as on Ethereum?A: Yes. ZetaChain uses the same ECDSA secp256k1 key derivation, so your Ethereum address remains valid and interoperable.

Q: Why does my ZETA balance show zero even after receiving tokens?A: This typically occurs if ZETA was sent before the network was added to MetaMask. Refresh the account or manually add the ZETA token contract using the address provided above.

Q: Is it safe to interact with ZetaChain dApps through MetaMask’s built-in interface?A: Yes, provided the dApp domain is verified and the connection originates from an official link. Always inspect the connected network indicator before signing any transaction.

Q: Do I need ETH or another bridged asset to pay for gas on ZetaChain?A: No. Gas fees on ZetaChain Mainnet are paid exclusively in ZETA. You cannot use ETH, USDC, or other tokens for base-layer transaction fees.
