Get Test ETH
To use Liberty Chain Testnet, you need test ETH to pay for gas fees. Since Liberty Chain settles on Ethereum Sepolia, the process is straightforward: get Sepolia ETH from a faucet, then bridge it to Liberty Chain.
Test ETH Has No Value
Test ETH on Sepolia and Liberty Chain Testnet has no real-world value. It is used solely for development and testing purposes.
Step 1: Get Sepolia ETH
First, you need Sepolia ETH in your wallet. Several faucets distribute free Sepolia ETH. Use any of the following:
| Faucet | Requirements | Amount |
|---|---|---|
| Google Cloud Web3 Faucet | Google account | 0.05 ETH per day |
| Alchemy Sepolia Faucet | Alchemy account | 0.5 ETH per day |
| Chainlink Faucet | GitHub or Twitter login | 0.1 ETH per request |
Multiple Faucets
If one faucet is rate-limited or down, try another. The Google Cloud faucet is reliable and does not require a crypto-specific account.
- Make sure your wallet is connected to the Ethereum Sepolia network. In MetaMask, select "Sepolia test network" from the network dropdown.
- Visit one of the faucets above and paste your wallet address.
- Complete any verification steps (login, CAPTCHA, etc.) and request test ETH.
- Wait for the transaction to confirm. Sepolia ETH should appear in your wallet within a minute.
Step 2: Bridge Sepolia ETH to Liberty Chain
Once you have Sepolia ETH, you can bridge it to Liberty Chain using the official bridge.
- Go to the Liberty Chain Bridge.
- Click Connect Wallet and approve the connection in your wallet. Make sure you are on Ethereum Sepolia.
- The bridge should show Sepolia as the source and Liberty Chain Testnet as the destination.
- Enter the amount of ETH you want to bridge. A small amount like 0.01 ETH is sufficient for testing.
- Click Bridge and confirm the transaction in your wallet.
- Wait for the bridge transaction to complete. Deposits from L1 to L2 typically take a few minutes to finalize.
- Switch your wallet to Liberty Chain Testnet (see Connect Wallet). Your bridged ETH should now be visible in your balance.
Bridge Direction Matters
Deposits (L1 to L2) complete in a few minutes. Withdrawals (L2 to L1) require a 7-day challenge period for security. For testing, it is easiest to keep your funds on Liberty Chain once bridged.
Verify Your Balance
After bridging, you can verify your balance in two ways:
- In your wallet — switch to Liberty Chain Testnet and check your ETH balance.
- On the explorer — visit the Liberty Chain Explorer and search for your wallet address to see your balance and transaction history.
