How to add Berachain Artio to MetaMask? (Testnet settings)

Understanding Berachain Artio Testnet

1. Berachain Artio is the official testnet for Berachain, a high-performance EVM-compatible Layer 1 blockchain built with Cosmos SDK and leveraging the Proof-of-Liquidity consensus mechanism.

2. Artio serves as the primary environment for developers to deploy smart contracts, test dApps, and validate interactions before launching on the mainnet.

3. It operates with its own native token — BERA — distributed through faucets for testing purposes only.

4. The network uses a distinct chain ID (80085), block explorer (https://artio.beratrail.io), and RPC endpoints separate from all other chains.

5. Unlike Ethereum or Polygon testnets, Artio requires manual configuration in MetaMask due to absence from the default network list.

Required Network Parameters

1. Network Name: Berachain Artio

2. New RPC URL: https://artio.rpc.berachain.com/

3. Chain ID: 80085

4. Currency Symbol: BERA

5. Block Explorer URL: https://artio.beratrail.io

Step-by-Step MetaMask Configuration

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

2. Select “Add Network” from the menu, then choose “Add a network manually”.

3. Paste the exact values for Network Name, New RPC URL, Chain ID, Currency Symbol, and Block Explorer URL into their respective fields.

4. Ensure no trailing slashes exist in the RPC URL except the one immediately following the domain.

5. Click “Save”. MetaMask will validate the connection and switch to the newly added network if successful.

Acquiring Testnet BERA Tokens

1. Navigate to the official Berachain faucet at https://artio.faucet.berachain.com.

2. Connect your MetaMask wallet using the “Connect Wallet” button.

3. Enter your wallet address and complete the CAPTCHA verification.

4. Submit the request. A standard allocation of 0.1 BERA is dispensed per address per 24-hour window.

5. Confirm receipt by checking your MetaMask balance or viewing transactions on the Artio block explorer.

Troubleshooting Common Issues

1. If MetaMask displays “Failed to fetch chain ID”, verify that the RPC URL is accessible via browser and not blocked by ad blockers or corporate firewalls.

2. Transactions stuck in pending state often result from incorrect gas settings; use “Low” or “Medium” presets and avoid custom gas limits unless explicitly required.

3. Missing BERA balance after faucet claim may indicate wallet still connected to another network — double-check active network selection in MetaMask.

4. Some dApps display “Unsupported Network” errors even after adding Artio — confirm the dApp officially supports Artio and has not hardcoded legacy RPC endpoints.

5. Importing tokens manually may be necessary for wrapped assets like wBERA; use the contract address 0x7507C9e02F717984a32f262E1495d8B3b253e352 on Artio to add it as a custom token.

Frequently Asked Questions

Q: Can I use the same wallet address on Artio and Berachain mainnet?A: Yes. Both networks share identical address formats since they are EVM-compatible and use the same key derivation scheme.

Q: Why does MetaMask show “Unknown Token” after adding Artio?A: This occurs because MetaMask does not auto-detect token contracts on custom networks. You must manually import any token you wish to view, including native BERA.

Q: Is it safe to input my seed phrase when configuring Artio?A: No seed phrase entry is required during network setup. Never enter your recovery phrase anywhere outside your wallet’s secure interface.

Q: Do I need to change MetaMask’s default currency display to see BERA values?A: MetaMask does not convert BERA to USD natively on testnets. Value display remains in raw BERA units unless integrated with third-party price oracles configured separately.
