# Use network testnets

> List of testnets supported by Dfns across each network, with notes on faucets, RPC endpoints, and feature parity with mainnet wallets.

### What is a testnet?

A **testnet** is a blockchain network used for testing purposes. Unlike the mainnet, transactions on testnets use **test tokens**, which have no real-world value.

Examples of popular testnets:

* Ethereum Goerli / Sepolia
* Polygon Mumbai
* Bitcoin Testnet
* Avalanche Fuji

The list of all supported testnets can be found on [the networks page](/networks)

<Steps>
  <Step title="Create a wallet for a testnet">
    You can create a wallet for a specific blockchain and network using the Dfns dashboard:

    Head to Operations > Wallets and click ":heavy\_plus\_sign: Create a Wallet".&#x20;

    Select a testnet network from the list (e.g. StellarTestnet) and give a name (e.g. "Stellar Testnet Wallet") and click Create. Finally, 🔑 sign the operation with your passkey and you obtain your new wallet!
  </Step>

  <Step title="Get test funds">
    Once your wallet is created:

    * Go to a **faucet** (test token distributor) for your chosen testnet.&#x20;
    * Provide your Dfns wallet address, visible on the "Address" field on your wallet page
    * Receive test tokens for development.

    Example Faucets are listed on [the networks page](/networks).
  </Step>

  <Step title="Check wallet balance">
    On your wallet page, the new assets/coins balance should be updated quickly.&#x20;

    You can also check that balance using the API: [Get Wallet](/api-reference/wallets/get-wallet)
  </Step>

  <Step title="Send a test transaction">
    Now that your wallet has test tokens, you can initiate a transaction.

    You’ll need to approve the transaction via your usual Dfns approval flow (e.g., 🔑 passkey, custom policy, etc.).

    You can then monitor the status on the wallet page. Once the transaction has been confirmed then it has been validated on the blockchain and is final.
  </Step>
</Steps>

<Warning>
  **Security Considerations**

  * Do not reuse Testnet wallets for Mainnet usage.
  * Treat API keys and credentials securely, even in test environments
  * Use approval policies for transaction verification even in test mode.
</Warning>
