How to configure MetaMask for Blast L2 mainnet? (Points Farming)

MetaMask Network Configuration Steps

1. Open MetaMask browser extension and click the network selector located in the top-left corner of the interface.

2. Select “Custom RPC” from the dropdown menu to manually input Blast-specific parameters.

3. Enter the following values precisely: Network Name = Blast Mainnet, New RPC URL = https://rpc.blast.io, Chain ID = 81457, Currency Symbol = ETH, Block Explorer URL = https://blastscan.io.

4. Click “Save” to finalize the configuration. The MetaMask interface will automatically switch to the Blast network.

5. Confirm successful activation by checking whether the network indicator displays “Blast Mainnet” and whether transaction history reflects activity on that chain.

Acquiring Native Blast ETH for Gas

1. Visit https://faucet.blast.io and connect your MetaMask wallet.

2. Ensure MetaMask is set to Blast Mainnet before initiating the faucet request.

3. Click the “Request 0.001 ETH” button and wait for confirmation in the wallet popup.

4. After confirmation, refresh MetaMask to observe the newly credited ETH balance under the Blast network tab.

5. Repeat the process if additional gas is needed, observing rate limits imposed per wallet address per day.

Bridge Assets from Ethereum Mainnet

1. Navigate to https://bridge.blast.io and connect your MetaMask wallet.

2. Select “Ethereum” as the source chain and “Blast” as the destination chain.

3. Choose ETH or USDB as the bridging token and enter the desired amount.

4. Initiate the bridge transaction and approve both the allowance and transfer steps in MetaMask.

5. Monitor the transaction status using BlastScan; finalization typically completes within 15–30 minutes.

Points Farming Interaction Flow

1. Access https://points.blast.io and authenticate with MetaMask while on Blast Mainnet.

2. Click “Start Farming” to initialize the points accrual mechanism tied to wallet activity.

3. Perform at least three distinct on-chain actions: swap tokens via BlastSwap, deposit liquidity into a BlastPool, and mint an NFT using BlastNFT Studio.

4. Each action triggers automatic points calculation based on gas spent, contract interaction depth, and data calldata size.

5. Points update in real time and appear under the “My Points” dashboard without manual refresh.

Troubleshooting Common Failures

1. If MetaMask fails to detect Blast RPC, verify that no ad blocker or privacy extension interferes with RPC endpoint loading.

2. When faucet requests return “Rate Limited”, check if the same wallet has already claimed within the past 24 hours using another browser profile.

3. A “Chain ID Mismatch” error indicates MetaMask is still pointing to a different L2 or testnet; re-enter Chain ID 81457 manually.

4. Bridging delays exceeding one hour suggest pending L1 confirmations—verify Ethereum block height and retry after six confirmations.

5. Missing points despite completed transactions may stem from unindexed event logs; wait up to 120 seconds for backend synchronization.
