How to use Phantom with Monad testnet? (Early access)

Phantom Wallet Integration

1. Phantom officially announced support for the Monad testnet on February 20, 2025, enabling direct access without manual RPC configuration.

2. Users can launch Phantom browser extension or mobile app and switch to the testnet environment via the network selector dropdown.

3. The wallet automatically detects Monad Testnet parameters including chain ID 10143 and correct RPC endpoint upon first interaction.

4. No custom network addition is required—Phantom handles chain metadata retrieval in real time from trusted sources.

5. Once selected, all subsequent transactions, token swaps, and DApp connections route exclusively through Monad’s testnet infrastructure.

Testnet Token Acquisition

1. Visit the official Monad testnet faucet at https://testnet.monad.xyz/ while connected to Phantom.

2. Input your Phantom wallet address and complete CAPTCHA verification to request MON test tokens.

3. Tokens are dispensed every 12 hours per address, enforcing fair distribution across early participants.

4. Alternative acquisition includes bridging from Sepolia using Orbiter Finance with Phantom connected as the source wallet.

5. Cross-chain transfers require prior ETH balance on Sepolia and confirmation of both source and destination chains within Phantom’s interface.

DApp Interaction Flow

1. Navigate to Monad-native decentralized applications such as Elixir liquidity protocol or Wormhole cross-chain interface.

2. Connect Phantom directly via wallet connect button embedded in each DApp UI.

3. Initiate a swap, add liquidity, or execute a cross-chain transfer to generate verifiable on-chain activity.

4. Confirm transaction signatures inside Phantom with appropriate gas fee estimation displayed pre-approval.

5. Track all interactions on Monad Explorer by pasting the transaction hash retrieved from Phantom’s activity log.

Security Verification Steps

1. Always verify that the network name shown in Phantom’s top bar reads “Monad Testnet” and not “Ethereum” or “Sepolia”.

2. Cross-check chain ID value (10143) against official documentation hosted at docs.monad.xyz before signing any transaction.

3. Avoid clicking external links claiming to offer MON airdrops unless sourced from @monad_xyz verified X account or official Discord announcements.

4. Disable auto-approval features in Phantom settings to enforce manual review of every contract call.

5. Export and store wallet seed phrase offline—never enter it into any web form or third-party service during testnet usage.
