Why you need Sepolia ETH before you launch on Ethereum
Ethereum mainnet gas is the most expensive of any chain MoonSale supports, which makes it the last place you want to discover a mistake in your token setup or presale configuration. Sepolia, Ethereum's primary testnet, mirrors mainnet behavior closely enough that anything you verify there translates directly to what you will see on mainnet, without spending a cent of real ETH to find out.
Running through Create Token or Create Presale on Sepolia first means you see the exact deployment flow, the exact confirmation screens, and your project's page exactly as it will appear, before committing real ETH to Ethereum mainnet.
What Sepolia testnet actually is
Sepolia is Ethereum's main proof-of-stake testnet, chain ID 11155111. It behaves like Ethereum mainnet in every way that matters for testing, block times, gas mechanics, EVM behavior, except SepoliaETH has no market value and cannot be withdrawn to anything real.
Key testnet details:
- Chain ID: 11155111
- RPC URL:
https://rpc.sepolia.org - Block explorer:
https://sepolia.etherscan.io - Currency symbol: ETH (shown as SepoliaETH in most wallets)
MoonSale's token factory, presale factory, and token lock contracts are deployed and verified for Ethereum, and Sepolia is the recognized testnet MoonSale uses to skip live-liquidity checks during testing, so anything you do here runs against real, audited contract logic.
What you need before you start
A wallet. MetaMask or any EVM-compatible wallet.
A few minutes, and in some cases a Google account, see the faucet options below for details on which ones need it.
Nothing real to spend. All three faucets below are free.
Step by step: claiming Sepolia ETH
Step 1: Copy your wallet address
Open your wallet, switch to (or add, see below) Sepolia, and copy your address.
Step 2: Try the Google Cloud Web3 faucet
Go to the Google Cloud Sepolia faucet, sign in with a Google account, and submit your wallet address. This faucet is reliable and well maintained precisely because it requires that Google sign-in as its anti-abuse measure, if you would rather not sign in, use the Alchemy faucet below instead.
Step 3: Use the Alchemy faucet if you want to skip account sign-in
The Alchemy Sepolia faucet requires no authentication at all. Paste your wallet address and submit, you can request testnet tokens again every 24 hours.
Step 4: Use the Chainlink faucet as a second backup
Chainlink's Sepolia faucet connects to your wallet through MetaMask, WalletConnect, or Coinbase Wallet, and dispenses SepoliaETH the same way as the others. Having three independent options means you are very unlikely to be stuck without testnet ETH.
Step 5: Confirm the tokens landed
Check your wallet balance, or paste your address into Sepolia Etherscan to see the incoming transaction confirm.
Adding Sepolia to your wallet
Most wallets, including MetaMask, include Sepolia as a built-in test network you can enable directly from settings without adding it manually, look for a "Show test networks" toggle. If you need to add it by hand, use:
- Network name: Sepolia
- New RPC URL:
https://rpc.sepolia.org - Chain ID: 11155111
- Currency symbol: ETH
- Block explorer URL:
https://sepolia.etherscan.io
When you connect your wallet on MoonSale while Sepolia is selected, MoonSale recognizes it automatically.
What to do with your Sepolia ETH on MoonSale
Once your wallet holds SepoliaETH and is switched to Sepolia, you can run the full MoonSale flow for free:
Deploy a test token. Create Token works identically on Sepolia, so you can see your token contract and page before spending real ETH on mainnet.
Walk through a test presale. Create Presale runs on Sepolia, letting you understand every setting, softcap, listing rate, vesting, before committing to a real launch on the most expensive chain MoonSale supports.
Check the security score preview. MoonSale's Security Score tooling runs the same checks on testnet deployments, useful for seeing how your setup scores before it is live.
If you are testing across multiple chains before choosing where to launch, How to Get Testnet BNB (tBNB) From the BNB Chain Faucet and How to Get Testnet Tokens From the Robinhood Chain Faucet cover the same process for MoonSale's other supported chains.
Frequently asked questions
Does SepoliaETH have any real value?
No. SepoliaETH cannot be traded, sold, or withdrawn to anything of value. It exists only to pay gas for test transactions on Sepolia, chain ID 11155111.
Do I need a Google account to get Sepolia ETH?
Only if you use the Google Cloud faucet. The Alchemy faucet requires no authentication at all, and the Chainlink faucet only requires connecting a wallet.
How often can I claim Sepolia ETH?
It varies by faucet. The Alchemy faucet allows a new request every 24 hours per wallet address, other faucets have their own similar cooldown windows.
How much Sepolia ETH do I need to test on MoonSale?
A single faucet claim is generally enough to deploy a test token and walk through a full test presale, since Sepolia gas mechanics mirror Ethereum mainnet closely but a single deployment does not require large amounts.
Is Sepolia the same as Ethereum mainnet?
No. They are separate networks, chain ID 11155111 for Sepolia versus chain ID 1 for Ethereum mainnet, with separate balances, though MoonSale's contracts are deployed and verified on both.
Can I test creating a presale without spending anything real?
Yes. With SepoliaETH in your wallet and Sepolia selected, Create Presale runs the exact same flow as Ethereum mainnet at zero real cost.
Why does Ethereum testing matter more than testing on other chains?
Ethereum mainnet gas is the highest of any chain MoonSale supports, so a mistake caught on Sepolia instead of mainnet saves meaningfully more than the same mistake would on a lower-gas chain.
What do I need to add Sepolia to my wallet manually?
Chain ID 11155111, RPC URL rpc.sepolia.org, currency symbol ETH, and block explorer sepolia.etherscan.io, though most wallets include Sepolia as a built-in test network already.
Ready to test your first launch?
With SepoliaETH in your wallet, run the full MoonSale flow on Ethereum at zero cost: Create Token or Create Presale. When you are ready to go live, the same audited contracts are already running on mainnet.
