The Sundial testnet faucet is a free service that gives you testnet sBTC, Sundial’s synthetic BTC token on the Sundial L2, so you can explore the protocol without risking any real funds. Testnet sBTC has no monetary value and cannot be transferred to any mainnet network. Every address can claim once per cooldown period, keeping the faucet available for all testers.
Testnet tokens have no monetary value. Never send real BTC or ADA to a testnet address, and do not reuse a wallet that holds real funds for testnet activity.

Testnet Network Details

Before you claim, make sure you have the following details:

​
Claim Testnet sBTC

1

Set your wallet to Preprod testnet

Open your wallet extension (Eternl, Lace, Typhon, Yoroi, GeroWallet, or NuFi) and navigate to its Settings or network selector. Switch the network from Mainnet to Testnet or Preprod.
If your wallet shows an address starting with addr1 instead of addr_test1, it is still on mainnet. Switch networks before continuing.
2

Copy your testnet payment address

Open the Receive screen in your wallet and copy your payment address. A valid testnet address always starts with addr_test1. This is the address the faucet will send sBTC to — no wallet connection or signature is required on the faucet page itself.
3

Go to the Sundial faucet

Navigate to sundialprotocol.com/testnet/faucet in your browser.
4

Paste your address and submit

Paste your addr_test1... address into the Sundial testnet address input field. Click Request testnet sBTC to submit the claim.
5

Confirm your claim

On success, the page displays a confirmation showing:
  • Grant amount — the amount of testnet sBTC sent to your address.
  • Next eligible at — the earliest time this address can claim again.
  • Claim ID and Transaction hash — reference IDs you can copy for your records.
Refresh your wallet’s balance (still on the Preprod testnet network) to see the sBTC appear. Because sBTC lives on the Sundial L2, it will not appear on standard L1 block explorers — your wallet balance and the faucet confirmation are the authoritative sources during the testnet phase.
Once you have testnet sBTC, use it to explore the full staking and withdrawal flows on the Sundial testnet dashboard without putting any real funds at risk. See the Stake ADA guide and Stake BTC guide to get started.

​
Troubleshooting Faucet Errors

Your address has already claimed testnet sBTC within its cooldown window. Each address must wait until the Next eligible at time shown in the last claim confirmation before it can claim again.To continue testing right away, switch your wallet to a different testnet address, or wait until the cooldown expires. You can generate additional testnet addresses from within your wallet extension.
The faucet only accepts standard Preprod payment addresses that start with addr_test1. Common causes:
  • Your wallet is still on Mainnet — mainnet addresses start with addr1 and will be rejected.
  • You copied a stake address (starts with stake_test1) instead of a payment address. Use the address from your wallet’s Receive screen, not the staking section.
  • You copied a script address or contract address. Use a regular wallet receive address.
Switch your wallet to Preprod, go to the Receive screen, and copy the address displayed there.
The faucet service may be momentarily unavailable. Wait a few minutes and try submitting your claim again. If the error persists for more than 15 minutes, report it to the Sundial team — this is useful testnet feedback.
The faucet wallet is temporarily low on testnet sBTC. The faucet is refilled periodically. Try again later — typically within a few hours.
A daily cap on total claims from a given browser or network has been reached. This limit exists to keep the shared faucet available for all testers. Try again later, or claim from a different network connection.
