Instructions on how to do a Testnet peg-in.

1 Connect a wallet to Bitcoin Testnet

We recommend to use Electrum BTC wallet for connecting to Bitcoin Testnet.

• Download the wallet from Electrum Website
• Install Electrum
• Start Electrum in Testnet mode
  • For example on MacOS: /Applications/Electrum.app/Contents/MacOS/Electrum --testnet
• After Electrum starts, create or import a wallet
• Go to the third tab, “Receive”. You will see a Bitcoin Testnet address like below.

Note: The Bitcoin wallet needs to be legacy (not Segwit) whose public key starts with either m or n, and private key starting with p2pkh:

2 Get test Bitcoin from Testnet Faucet

There are a few options to get Bitcoin on Testnet. We use https://testnet-faucet.mempool.co/

3 Whitelist Bitcoin address in RSK

You can contact us in RSK official Gitter channels to whitelist your Bitcoin Testnet address.

4 Send Bitcoin to RSK Federation address

The RSK Federation address is retrieved by making a Smart Contract call on RSK Testnet. In order to make the call, you will need to have MyCrypto installed, select RSK Testnet in “More Networks”, and Navigate to “MyCrypto -> Contracts -> Select Existing Contracts -> “Bridge” -> “getFederationAddress” to execute the call. It should look like the screenshot below.

Once you have the RSK Federation address, you can send Bitcoin to it from your whitelisted Bitcoin address.

Note: You need to send a minimum amount of 0.01 BTC for conversion.

5 Get tR-BTC address with tBTC private key

You can get a corresponding tR-BTC address with your tBTC private key from https://github.com/rsksmart/utils.

Note: when entering Bitcoin private key do not include p2pkh: in the front.

6 Check tR-BTC balance on Testnet

You can check balance of above tR-BTC address on Metamask, MyCrypto or any RSK Testnet compatible wallets.

Note: You have to wait a minimum of 100 confirmations + a minimum of 5 minutes for checking your R-BTC balance
