Using Networks' Testnets

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 Supported networks

1

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 "➕ Create a Wallet".

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!

2

Get test funds

Once your wallet is created:

  • Go to a faucet (test token distributor) for your chosen testnet.

  • Provide your Dfns wallet address, visible on the "Address" field on your wallet page

  • Receive test tokens for development.

Example Faucets are listed on Supported networks

3

Check Wallet Balance

On your wallet page, the new assets/coins balance should be updated quickly.

You can also check that balance using the API: Get Wallet by ID

4

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.

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.
