BTC to R-BTC conversion

Instructions on how to do a Mainnet peg-in.

1 Get a BTC address with balance

Any Bitcoin wallet that supports legacy (p2pkh) private key works for this step, and here we recommend to use Electrum BTC wallet for connecting to BTC Mainnet.

• Download the wallet from Electrum Website
• Install Electrum
• Start Electrum
• Once 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 Whitelist Bitcoin address in RSK

You need to complete whitelisting.

3 Send Bitcoin to RSK Federation address

The RSK Federation address is retrieved by making a Smart Contract call on RSK Mainnet. In order to make the call, you will need to have MyCrypto installed, select RSK Network, 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.

4 Wait for BTC confirmations

To ensure the transaction, we need to wait 100 BTC confirmations, be patient :)

100 blocks * 10 minutes/block = 1000 minutes = 16.667 hours approx.

5 Get R-BTC address with BTC private key

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

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

6 Check R-BTC balance

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

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

Note: The minimum amount to send is 0.008 R-BTC for Mainnet Gas Limit of the transaction needs to be manually set at 100,000 gas; otherwise the transaction will fail. Gas Price can be set to 0.06 gwei.

You can either use Electrum wallet downloaded earlier or from any Bitcoin explorer to check the balance.
