zkSync is a zero-knowledge L2 solution that focuses on making transaction fees as small as possible. It makes the framework very useful for blockchain development and usage, and its zkSync Sepolia testnet helps developers try their apps before releasing them. Tokens here have no value; therefore, it’s impossible to lose anything while working here.
Here, we explore how to obtain a GetBlock endpoint for blockchain access and add it to MetaMask to obtain free test ETH there.
What is zkSync Sepolia?
An Ethereum framework zkSync helps maintain small transaction fees while remaining highly stable and secure. Its testnet is where developers can test their apps without spending anything, as all ETH here has no value. Therefore, operations don’t require cost, saving developers money and creating an efficient testing ecosystem.
To obtain test ETH, here is a zkSync faucet at GetBlock. Let’s see how to deal with the testnet before proceeding to faucets.
Adding zkSync Testnet to MetaMask: Preparatory Steps
Before registering in GetBlock, ensure that you have a MetaMask wallet. When registering, use it as your login credentials. After that, let’s see how to add zkSync to MetaMask and where to start.
- Choose zkSync protocol among My endpoints.
- Select Sepolia network and JSON-RPC API/add-on.
- Click Get to obtain an endpoint.
This endpoint is a unique connection link.
It provides you with 40,000 free requests per day, at a limited speed of 60 requests per second. While it’s more than enough for everyday use, you may need more if you have large-scale dApps with many users. For that, consider our paid shared nodes from $29/month and dedicated nodes from $600/month, if you need to support thousands of users.
How to Add zkSync Sepolia to MetaMask: Tutorial
Let’s see how to add the obtained token to MetaMask to have the network connected to your wallet.
Step 1: Add zkSync Sepolia network
In the MetaMask extension, start adding the zkSynk testnet.
- Open the three-dots icon on the top right, and click Settings;
- In the lower part of the list, select the Network item;
- On the next tab below, click on the blue button labeled Add network.
- Proceed to the new browser tab, scroll down, and click Add a network manually.
After accessing the form, type Sepolia zkSync characteristics here.
Step 2: Arrange zkSync Sepolia Parameters
See the network parameters below: it’s all that you need to access the network.
| Network | zkSync Sepolia |
|---|---|
| RPC URL | https://go.getblock.io/<Your_Access_Token> |
| Chain ID | 300 |
| Currency | ETH |
| Block Explorer | https://sepolia.explorer.zksync.io/ |
After adding parameters, check everything, see that there are no errors, and click Save.
Step 3: Select zkSync Sepolia Network
You can switch to the new network instantly, and to select it manually, proceed to the network list in the upper left of the extension. See the current balance above, and note that no zkSynk Sepolia bridge is allowed. To get test ETH, use faucets.
Let’s look closer.
How to Get zkSync Test ETH on MetaMask?
Here is how to use the GetBlock faucets.
- In the list, select the zkSync Sepolia Faucet and click Try Now.
- Enter your wallet address and click Claim Token.
- A captcha will appear, and you need to solve it to obtain test ETH.
Soon, your test funds will arrive. Start experimenting: send some to test accounts, connect to dApps, and see what can happen. But remember, they have no real value, and so you cannot pay for anything with them or send them to mainnet. No zkSync testnet bridge is possible, so avoid those who claim otherwise.
Conclusion
With the testnet network, developers can test the network methods and applications in it without expenses. Tokens have no value, so you cannot lose anything when operating with them, but remember that you cannot buy anything with them either. Use zkSync testnet faucet at GetBlock to get free test ETH, and then try to experiment with them.
