In this tutorial you will learn how to:
|
|
1. Create a Sepolia Ethereum account and obtain its private key.
|
|
2. Obtain Sepolia ETH from faucet.
|
|
3. Access a node on the Sepolia testnet using Infura.
|
|
|
|
## 1. Create a Sepolia Ethereum account and obtain its private key
|
|
|
|
> _**WARNING:**_ The private key is used elsewhere by Waku RLN registration tools to assist with membership registration in the Sepolia test network.
|
|
> We strongly recommend that you create an account only for this purpose.
|
|
> NEVER expose a private key that controls any valuable assets or funds.
|
|
|
|
1. Download and install Metamask. [https://metamask.io/download/](https://metamask.io/download/)
|
|
If you already have Metamask installed, go to step 3.
|
|
If you encounter any issues during the Metamask setup process, please refer to the [official Metamask support page](https://support.metamask.io/hc/en-us).
|
|
2. Create a new wallet and save your secret recovery phrase.
|
|
|
|
|
|
|
|
3. Login to Metamask.
|
|
|
|
|
|
|
|
4. By default, Metamask connects to the Ethereum Mainnet (dropdown menu in the top right corner).
|
|
|
|
|
|
|
|
To publish messages to the Waku Network, you need to connect to the Sepolia test network.
|
|
5. Switch to the Sepolia test network by selecting it from the dropdown menu. Ensure "Show test networks" is enabled.
|
|
|
|
|
|
|
|
The same account can be used with different networks. Note that the ETH balance is different for each network (each has its own native token).
|
|
|
|
|
|
|
|
6. To view the private key for this account, click on the three dots next to the account name and select "Account Details".
|
|
|
|
|
|
|
|
Select "Show Private Key".
|
|
|
|
|
|
|
|
Enter your Metamask password and click "Confirm"
|
|
|
|
|
|
|
|
You will be shown the private key.
|
|
|
|
## 2. Obtain Sepolia ETH from faucet
|
|
|
|
Sepolia ETH can be obtained from different faucets.
|
|
Three popular examples include:
|
|
|
|
1. [sepoliafaucet.com](https://sepoliafaucet.com/) (requires an Alchemy account)
|
|
2. [Infura Sepolia faucet](https://www.infura.io/faucet/sepolia) (requires an Infura account)
|
|
3. [Sepolia POW faucet](https://sepolia-faucet.pk910.de/)
|
|
|
|
> _**NOTE:**_ This list is provided for convenience. We do not necessarily recommend or guarantee the security of any of these options.
|
|
|
|
Many faucets limit the amount of Sepolia ETH you can obtain per day.
|
|
We include instructions for [sepolia-faucet.pk910.de](https://sepolia-faucet.pk910.de/) as an example:
|
|
|
|
1. Enter your Sepolia Ethereum account public address, solve the Captcha and start mining.
|
|
|
|
|
|
|
|
2. Keep the browser tab open for a while. You can see the estimated Sepolia ETH mined per hour.
|
|
|
|
|
|
|
|
Each session is limited to a few hours.
|
|
3. When you've mined enough Sepolia ETH (minimum of 0.05 Sepolia ETH), click on "Stop Mining" and claim your reward.
|
|
|
|
|
|
|
|
## 3. Access a node on the Sepolia testnet using Infura
|
|
|
|
> _**NOTE:**_ Infura provides a simple way of setting up endpoints for interaction with the Ethereum chain and the Waku RLN smart contract without having to run a dedicated Ethereum node.
|
|
> Setting up Infura is not mandatory. Operators concerned with the centralized aspect introduced by Infura should use their own node.
|
|
|
|
1. Sign up for Infura if you do not have an account already. [https://infura.io/register](https://infura.io/register)
|
|
|
|
|
|
|
|
Follow the instructions to register and verify the account.
|
|
|
|
2. Click on "Create a new API key".
|
|
|
|
|
|
|
|
4. Select "Web 3 API", give your API key a descriptive name and click on "Create".
|
|
|
|
|
|
|
|
You will be presented with a dashboard for the newly created key.
|
|
|
|
|
|
|
|
4. Select "Sepolia" in the dropdown menu for Ethereum.
|
|
|
|
|
|
|
|
Both Https and WebSockets endpoints are available. Waku requires the WebSockets endpoint.
|
|
|
|
|
|
|
|
5. Copy this address (starting with `wss://sepolia.infura`) as needed when setting up your Waku node.
