A testnet is a testing network that operates with the same mechanism as a blockchain's production environment (mainnet). It allows you to test DApps and practice sending transactions without using real assets.

A faucet is a service that distributes testnet tokens for free. Since you need test tokens as gas fees for testnet operations, you obtain them from a faucet. Just like a water faucet, it lets you receive test tokens whenever you need them.

This guide primarily covers the process using Ethereum's Sepolia testnet, but the basic flow is the same for other chains.

The table below summarizes testnet faucet information for major blockchains.

💡 Tip: If you first obtain Sepolia ETH on Ethereum, you can bridge it to L2 testnets like Arbitrum and Base.

Here, we'll walk through the steps to receive Sepolia test ETH using the Rabby wallet.

What You'll Need

• Rabby wallet (mobile app or browser extension)
• Internet connection

Network Setup

1. Open the Rabby wallet.

2. Add a custom network.

Tap the network name displayed at the bottom of Rabby (e.g., "Ethereum"). From the "Select Chain" tab, choose "Custom Network" and press "Add Custom Network."

3. Add the Sepolia testnet.

On the "Add Custom Network" screen, select "Quick add from chainlist" and type "Ethereum Sepolia" in the search box.

• Currency: ETH
• ID: 11155111

Select it and press "Confirm" to complete adding the network.

4. Switch to the network.

Follow the same steps to switch to the Sepolia testnet you just added.

Access the Faucet Site

5. Go to a faucet site.

Open one of the following faucet sites in your browser:

• Sepolia PoW Faucet
• Google Cloud Faucet
• Alchemy Faucet

⚠️ Note: Some faucet sites may require you to log in with a Twitter account. Follow the on-screen instructions if prompted.

Receiving Test Tokens

6. Enter your wallet address to receive test ETH.

Paste your wallet address into the input field on the faucet site and click the "Receive" button.

7. Confirm the test ETH has arrived.

Go back to the Rabby wallet and wait for the balance to update (this may take 1–2 minutes).

Switch the tab to "Custom Network" and verify that Sepolia ETH has been added — if so, you've successfully received your test tokens.

Testnet participation isn't just for practice — it can also lead to future airdrop rewards.

In the past, testnet participants received mainnet airdrops from the following projects:

• Arbitrum: Testnet activity was one of the criteria for the ARB token airdrop
• Optimism: Early testnet participants received OP tokens
• StarkNet: Users who executed transactions on the testnet were eligible for STRK token distribution

Since testnet participation is free with virtually zero risk, we recommend actively using testnets for any projects that interest you.

Candy Drops is running a collaboration campaign with the FSA-licensed crypto exchange "OKJ." By registering through this link, you can receive 1,000 yen worth of Bitcoin.

Furthermore, by completing KYC and verifying tasks on the Candy Drops My Page, you can earn 50,000 Candy Drops points that can be used to enter regularly held campaigns.

Tips for Targeting Airdrops

1. Participate early when a new project's testnet launches
2. Execute transactions on the testnet regularly, not just once
3. Actually use DApps on the testnet (swaps, lending, etc.)
4. Join official Discord and community channels to stay updated
