Scroll is a zero-knowledge (ZK) L2 solution with robust scaling features and fixed transaction costs. For development purposes, it has a Scroll Sepolia testnet where tokens have no value and therefore can be used to test applications without potential loss.
Let’s see how to add this testnet to your MetaMask account, get test ETH, and use it for application testing.
What is Scroll Sepolia?
Scroll is an Ethereum framework to make transactions quicker and more efficient. With its zero-knowledge architecture, it’s very secure and can be scaled without a speed decrease. Its testnet is a separate network where tokens cannot be purchased or sold, and, therefore, operations require no cost.
Instead, a specific tool, a Scroll faucet, is used to obtain test ETH in the network. Before accessing it, let’s see how to work with the testnet.
Adding Scroll Testnet to MetaMask: Preparatory Steps
Here, you need two things:
- a MetaMask account;
- a JSON-RPC endpoint.
The former is your wallet where you store your test ETH obtained from the Scroll testnet faucet. The latter is the tool to interact with the blockchain. Registering in MetaMask is easy: just create a new wallet or generate an existing one with your seed phrase.
- Register at GetBlock using MetaMask address.
- Choose Scroll protocol in the My endpoints dashboard menu.
- Select Sepolia network and JSON-RPC API/add-on.
- Click Get to obtain a free Scroll access token.
Let’s now see how to add Scroll to MetaMask. This token provides you with free 40,000 blockchain requests limit, at a speed of 60 transactions per second. It’s more than enough for personal use, and for commercial blockchain applications, consider shared and dedicated nodes where these numbers are much higher. Prices start from $29/month.
How to Add Scroll Sepolia to MetaMask: Tutorial
Let’s see how to add the Scroll testnet to MetaMask, where you’ll operate with your test coins.
Step 1: Add Scroll Sepolia network
Click on the MetaMask extension and let’s start.
- Open the three-dots icon on the top right, and click Settings;
- Select the Network item;
- On the next tab below, click Add network.
- Proceed to the new browser tab, and click Add a network manually below.
After that, you need to add Sepolia Scroll parameters.
Step 2: Arrange Scroll Sepolia Parameters
Here they are. Use the token you’ve obtained earlier at GetBlock.
| Network | Scroll Sepolia |
|---|---|
| RPC URL | https://go.getblock.io/<Your_Access_Token> |
| Chain ID | 534351 |
| Currency | ETH |
| Block Explorer | https://sepolia.scrollscan.org/ |
After adding parameters, including the GetBlock token, click Save and switch to the network instantly.
Step 3: Select Scroll Sepolia Network
You’ll see the new network in your MetaMask interface. The network list that can be accessed in the upper left. Note that no Scroll testnet bridge is allowed, and you cannot buy, sell, or swap any test coins. To get them, use faucets.
How to Get Scroll Test ETH on MetaMask?
Here at GetBlock, we have faucets for this purpose. Let’s see how to use it.
- In the faucet list, select the Scroll Sepolia Faucet and click Try Now.
- After that, enter your address and click Claim Token.
- Complete a captcha to obtain test coins as a reward.
After some time, your funds will arrive. Start experimenting as you want, as no losses can be suffered here, and you can always have another test ETH when necessary. Conversely, you can donate excessive coins to our faucet.
Remember, no Scroll Sepolia bridge is possible, you can only transfer to another testnet address.
Conclusion
Testnets help developers see their dApps in action without losing any real coin. Thus, they are very useful in all development stages, from concept verification to user testing. After adding Scroll testnet to MetaMask, use our free faucet to obtain test ETH on it, and start experimenting with the network methods and dApps.
