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
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 Wallet. Give it a name, select a testnet network from the list (e.g. StellarTestnet), and click Create. Sign the operation with your passkey and you obtain your new wallet.

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.
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
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.
