Bitget Wallet
This guide explains how to bridge your Bitcoin (BTC) from the Bitcoin network to mint $zkBTC on Ethereum networks using the Bitget Wallet extension.
Step 1. Install Your Bitget Wallet
Click the "Connect Wallet" button on the bridge interface. Select Bitget Wallet from the list of available wallets.
Ensure your wallet is connected to the Bitcoin mainnet.
Step 2. Click the zkBTC Bridge website and connect with Bitget wallet
Amount to Bridge: Enter the amount of BTC you want to bridge
Minimum: 21,000 sats (0.00021 BTC).
Amounts below this will fail
Enter ETH Receiving Address: Enter your Ethereum address carefully
This is where your zkBTC will be delivered
Double-check this address for accuracy
Step 3. Review and Sign
Bitget Wallet will display a transaction ready for signing
Carefully review:
Transaction amount
Network fees
Destination details ( your ETH receiving address)
Important: Verify the OP_RETURN data matches your receiving ETH address
You must manually decode the OP_RETURN value to confirm it contains your correct ETH address as Bitget Wallet currently cannot display it in the signature comfirmation.
Step 4. Confirm Transaction
Sign the transaction in your Bitget Wallet. $zkBTC will be minted to your Ethereum address shortly.
Transaction may take several minutes to complete.
Important Notes
Minimum bridge amount: 21,000 sats (0.00021 BTC)
Always double-check all address fields before broadcasting
Manually verify the OP_RETURN data contains your correct ETH address
Network congestion may affect processing times
Keep sufficient BTC for transaction fees
