Bitcoin testnet

The Bitcoin testnet is a network that behaves almost exactly the same as the Bitcoin mainnet. The major difference is that the bitcoin on the testnet do not have any economical value, they should not be used to buy or sell goods and services. This makes the network very useful for testing software and features, because there is no risk of losing precious "real" bitcoin from the main network.

Don't loose your bitcoin

When testing cutting edge software like Wasabi, use testnet to ensure that your mistakes don't cost you money!

Bitcoin testnet network activated in Wasabi Wallet

When Wasabi is started in testnet, it will fetch testnet BIP 158 block filtersopen in new window from the coordinator. For the first start, this may take a couple of minutes.

After the testing, set the settings back to mainnet, and close Wasabi. It will load on mainnet the next time you start it.


Alternatively, you can edit the Config.json file in your Wasabi data folder. In the second line you can modify the value of "Network":, to "Main", "TestNet", or "RegTest". The changes will apply on the next launch of Wasabi.

Loading a wallet

Wasabi differentiates between Mainnet and TestNet wallets. Meaning that a TestNet wallet will not show up when the Main network is active, and vice versa. You have to create a new wallet when you activate TestNet for the first time.

Receiving testnet bitcoin

You can generate a receive address the same way as on mainnet, by labeling the known by entities in the Receive dialog. Notice that testnet SegWit addresses start with tb1q..., and not with bc1q... as mainnet addresses.

Because testnet bitcoin don't have economical value, they are gifted by different sources. There are faucetsopen in new window like this oneopen in new window or bitcoinfaucet.uo1.netopen in new window that give a certain amount of testnet bitcoin per time period. You may also ask other developers if they have a couple of spare testnet coins available.

Coinjoin on testnet

CoinJoin on testnet is as easy as on mainnet. Usually there are other testers doing a coinjoin, but if you are the only one at the moment, then load two wallets and start coinjoining in both of them.
