2.Claim t-btc(testnet btc) from the BTC faucet

BTC Faucet1:

BTC Faucet2:

4.Claim BOR

On Twitter, @BoringDAO_Defi account and post your ETH address (the mainnet and Ropsten will share the same address) to receive testnet BOR token (usually takes less than 24 hours to receive testnet token).

5. Add BOR and bBTC to Metamask

Testnet BOR contract address: 0x43dC152f50fEd0F24bF38E044001A64A377864c2

Testnet bBTC contract address: 0xe250b099AA55C20cdC98A60e8756Fe75223c313A

6. The BoringDAO Website

Enter the BoringDAO website, connect to the Ethereum wallet and the BTC address

Click “Unlock Wallet” to connect to your Ethereum wallet and enter your BTC address for the connect operation.

Make sure that you are operating on Ropsten Ethereum Testnet.

7. Minting and destroying coins


Enter the amount of BTC you wish to be minted and click “Mint”

Note: For a successful minting process, users MUST transfer BTC to the BoringDAO multi-signature address from the designated BTC address that they entered from step 6.

Transfer the testnet BTC (received from the faucet in step 2) to the multi-signature address, wait for 1 block confirmation, check if you have received bBTC and BOR, and complete the minting process.


Enter the number of bBTC to be burned on the Burn page and click “Approve”. After clicking “Approve”, Metamask will call a contract operation. After the “Approve” operation is successful, click “Confirm” to complete the burning process.

Note: When receiving BTC during the burning process, users must use the designated Bitcoin wallet that they entered in step 6. If users wish to receive BTC with another wallet, they should change their destination Bitcoin address before initiating the burning process. Users may not receive bBTC or redeem BTC if the destination address does not match with the designated address entered by the user in step 6.

8. Pledge and Redemption

Enter the amount of BOR token to be pledged. Before officially pledging BOR token, users need to first click “Approve” to give the contract permission to transfer BOR.

After clicking “Approve”, click “Confirm”. The pledged amount cannot be greater than the current BOR balance in your wallet, otherwise the Confirm button cannot be clicked.

Switch to the Redeem page. There is a Pledged amount on the “BOR” page that shows how many BORs have been pledged by the given user.

Enter the amount of BOR that needs to be redeemed and click “confirm” to redeem. It should be noted that there is a lock-up period after redeeming, and in the testnet the parameter is set to 1 hour, meaning you will receive your testnet BOR token 1 hour after initiating the redemption process. For instance, after a user clicks “redeem” to complete the Ethereum transaction, the total pledged amount will become 0, but the Unlocked Rewards amount below will not immediately available. You need to wait for 1 hour (lock-up period is set to 1 hour on Ropsten Testnet, and 24 hours for our Mainnet). After 1 hour when the lock-up period has ended, users can click on “Withdraw” button to receive the BOR.

9. Claim

After BOR is pledged into the tunnel, users can earn BOR whenever bBTC is being minted or destroyed in the tunnel. The website will display the fee to be collected by the pledger. After clicking “Claim”, users can receive the earned BOR token to their Ethereum account.
