# Getting Testnet Tokens

To test AstralBeam, you'll need testnet tokens on both Ethereum Sepolia and Casper Testnet. This guide provides links to faucets and instructions for obtaining test tokens.

## Overview

Testnet tokens have no real value and are only for testing. You'll need:

1. **Native tokens** for gas fees (Sepolia ETH, Testnet CSPR)
2. **Bridgeable tokens** to test the bridge (USDC, WETH, LINK)

## Native Tokens (For Gas Fees)

### Sepolia ETH

Required for paying gas fees on Ethereum Sepolia.

| Faucet                                                                     | Amount        | Requirements |
| -------------------------------------------------------------------------- | ------------- | ------------ |
| [Alchemy Sepolia Faucet](https://www.alchemy.com/faucets/ethereum-sepolia) | 0.1 ETH       | Free account |
| [PoW Mining Faucet](https://sepolia-faucet.pk910.de/)                      | Up to 2.5 ETH | Mining time  |
| [Infura Faucet](https://www.infura.io/faucet/sepolia)                      | 0.5 ETH       | Free account |

**Recommended**: The PoW mining faucet provides the largest amount without strict limits.

#### How to Get WETH

1. Go to [Uniswap](https://app.uniswap.org/explore/tokens/ethereum_sepolia/0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14?inputCurrency=NATIVE\&outputCurrency=0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14)
2. Connect MetaMask on Sepolia
3. Swap ETH for WETH
4. Keep some ETH for gas fees!

**WETH Address (Sepolia):** `0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14`

### LINK (Chainlink)

Chainlink's official LINK on Sepolia.

## Adding Tokens to MetaMask

After obtaining tokens, you may need to add them to MetaMask to see balances:

### Method 1: Import Token

1. Open MetaMask
2. Click "Import tokens"
3. Enter the token contract address
4. Token symbol and decimals will auto-populate
5. Click "Add Custom Token"

### Method 2: Token Detection

MetaMask may automatically detect tokens. If not:

1. Go to Settings > Security & Privacy
2. Enable "Autodetect tokens"

## Token Addresses Reference

## Tips for Getting Faucet Tokens

1. **Daily limits**: Most faucets have rate limits. Plan ahead.
2. **Multiple faucets**: Use different faucets to accumulate tokens faster.
3. **Save tokens**: Once bridged, you can bridge back instead of getting new tokens.
4. **Network congestion**: Faucet transactions may be slow during high network usage.
5. **Verification**: Some faucets require Twitter/GitHub verification.

## Troubleshooting

### Faucet Not Working

* Check if faucet has rate limits (wait and try again)
* Verify you're on the correct network
* Try a different faucet
* Check faucet's social media for status updates

### Tokens Not Appearing

* Wait a few minutes for transaction confirmation
* Add token manually to MetaMask using contract address
* Check transaction on Etherscan
* Ensure you're on Sepolia network

### Insufficient Balance Errors

* Native tokens (ETH/CSPR) are needed for gas
* Don't swap all your ETH - keep some for gas
* Gas prices vary - you may need more during congestion

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.astralbeam.io/using-astralbeam/getting-testnet-tokens.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
