How to add Taiko network to MetaMask?

Adding Taiko Network to MetaMask

1. Open MetaMask and click the network selector dropdown located at the top of the interface.

2. Select “Add Network” or “Custom RPC” depending on your MetaMask version.

3. Enter the following parameters for the Taiko Katla testnet: Network Name: Taiko Katla, RPC URL: https://rpc.katla.taiko.xyz, Chain ID: 17000, Currency Symbol: ETH, Block Explorer URL: https://explorer.katla.taiko.xyz.

4. Click “Save” to confirm the configuration. MetaMask will now display “Taiko Katla” in the network list.

5. Switch to the newly added network by selecting it from the dropdown menu. Your wallet balance will reflect zero ETH unless you have bridged or minted test assets.

Acquiring Test ETH for Taiko Interaction

1. Navigate to the Holesky testnet faucet at https://faucet.quicknode.com/ethereum/holesky.

2. Connect your MetaMask wallet and ensure it is set to the Ethereum Holesky network.

3. Click “Continue”, then select “Send me 1 ETH” to request test ETH.

4. After confirmation, wait approximately 30–90 seconds for the transaction to settle on Holesky.

5. Once received, switch MetaMask to the Taiko Katla network and proceed to bridge the Holesky ETH using the official Taiko bridge.

Using the Taiko Bridge for Asset Transfer

1. Visit https://bridge.katla.taiko.xyz and connect your MetaMask wallet.

2. Ensure your wallet is set to the Holesky network before initiating the bridge.

3. Select “ETH” under the token section and enter the amount you wish to transfer.

4. Click “Bridge” and approve both the allowance and bridge transactions in MetaMask.

5. Monitor the status on the bridge UI. Finality typically occurs within 5–15 minutes, after which ETH appears on the Taiko Katla network.

Interacting with Taiko dApps and Swaps

1. Access the Taiko swap interface at https://swap.katla.taiko.xyz/#/swap.

2. Confirm your wallet is connected and set to the Taiko Katla network.

3. Choose a supported token pair such as ETH/USDC and input the desired swap amount.

4. Review slippage tolerance and click “Swap”, then approve the transaction in MetaMask.

5. Perform at least three distinct swaps across different pairs to increase interaction depth and qualify for potential engagement metrics.

Frequently Asked Questions

Q: Why does MetaMask show “Unknown network” after adding Taiko Katla?A: This occurs when Chain ID 17000 is mismatched or the RPC endpoint fails to respond. Verify the RPC URL is exactly https://rpc.katla.taiko.xyz and that no trailing slash or typo exists.

Q: Can I use the same wallet address on Taiko Katla and Ethereum mainnet?A: Yes. Wallet addresses are deterministic across EVM-compatible chains. Your private key generates identical addresses on all chains supporting the same derivation path.

Q: Is it safe to approve unlimited allowances on Taiko testnet contracts?A: Yes. All tokens on Taiko Katla are non-transferable outside the test environment and hold no economic value. Unlimited approvals pose no financial risk.

Q: What happens if my bridge transaction stalls on the Holesky side?A: Check https://holesky.etherscan.io using your wallet address. If the transaction is pending, increase gas fee via MetaMask’s transaction speed-up feature or resend with higher priority.
