Bitlayer Official Bridge Cross-Chain (Bridge-In) Tutorial

·

Welcome to the definitive guide for performing cross-chain transactions on Bitlayer, the fully EVM-compatible Bitcoin Layer 2 network. Whether you're new to blockchain or an experienced user, this step-by-step tutorial will walk you through the entire Bitlayer bridge-in process with clarity and precision.

As a Bitcoin L2 scaling solution, Bitlayer enables BTC holders to unlock DeFi, smart contracts, and high-speed transactions while remaining anchored to Bitcoin’s security. To participate, you’ll need to bridge your BTC from the main Bitcoin chain into the Bitlayer ecosystem. Let’s get started.

🔧 Prerequisites for Cross-Chain on Bitlayer

Before initiating any cross-chain activity, ensure you have the following ready:

👉 Start bridging your BTC to Bitlayer today with a secure EVM wallet setup.

Bitlayer supports seamless integration between Bitcoin wallets and Ethereum Virtual Machine (EVM) environments. While Unisat Wallet handles your BTC assets, your EVM wallet will manage interactions within Bitlayer’s DeFi and dApp ecosystem.

If you don’t yet have an EVM wallet, creating one takes only minutes and follows a similar process to setting up Unisat Wallet. Just download the extension, create a secure seed phrase, and confirm your recovery words.

🚀 Step-by-Step: How to Bridge BTC to Bitlayer

Follow these clear steps to successfully complete your cross-chain transfer from Bitcoin to Bitlayer.

Step 1: Visit the Official Bitlayer Bridge

Navigate to the official Bitlayer website: https://www.bitlayer.org/
Click on “Bridge & Earn” to access the cross-chain bridge interface.

⚠️ Security Tip: Always verify the correct domain. Scammers often create fake sites with similar URLs. Only use links shared through Bitlayer’s official social media channels.

Step 2: Connect Your Unisat Wallet

Click “Connect Wallet”, then select “UniSat Wallet” from the options.
Your browser extension will prompt you to approve the connection—confirm to proceed.

Once connected, your BTC address and balance will be visible on the bridge interface.

Step 3: Enter the BTC Amount to Bridge

Input the amount of BTC you wish to transfer to Bitlayer. Keep these two critical requirements in mind:

Ensure the amount you enter is less than your total balance to cover the network fee. For example, if you have 0.0006 BTC, you can only bridge up to 0.00045 BTC.

Step 4: Connect Your EVM-Compatible Wallet

Click “Connect Wallet” again—this time to link your EVM wallet (e.g., MetaMask, OKX Wallet, or Bitget Wallet).
Choose your preferred option and follow the prompts to authorize the connection.

👉 Securely connect your EVM wallet and begin exploring Bitlayer’s DeFi opportunities.

This dual-wallet setup ensures that your BTC is securely transferred from the Bitcoin network while enabling full functionality within Bitlayer’s EVM environment.

Step 5: Finalize the Transfer

After both wallets are linked:

  1. Click “Next”, then confirm by clicking “Link”
  2. Once confirmed, click “Transfer”
  3. Your Unisat Wallet extension will pop up—review the transaction and click “Sign”

The bridge process is now initiated. You’ll see a transaction status window appear.

🕒 Understanding Transaction Status

After signing:

The displayed arrow icon shows your Bitlayer BTC address, where funds have been credited.

📌 Note: The example shown in some guides uses 0.00011 BTC for testing—this is below the minimum threshold and should not be used in production. Always adhere to the 0.0005 BTC minimum.
