Bridging Bitcoin (BTC) to emerging Layer 2 networks is a powerful way to unlock new utility for your holdings. Bitlayer, as a BTC-native Layer 2 scaling solution, enables Bitcoin to participate in decentralized finance (DeFi), smart contracts, and high-speed transactions—while maintaining the security of the Bitcoin base layer.

This comprehensive guide walks you through the official Bitlayer cross-chain bridge process using OKX Wallet, with step-by-step instructions designed for both beginners and experienced users. Whether you're exploring Bitcoin L2 ecosystems for the first time or expanding your multi-chain strategy, this tutorial ensures a smooth and secure onboarding experience.

Understanding Bitlayer and Its Cross-Chain Functionality

Bitlayer is an EVM-compatible Layer 2 network built specifically for Bitcoin. It allows BTC holders to bridge their assets and access DeFi, NFTs, and Web3 applications without leaving the Bitcoin ecosystem’s security umbrella.

The official Bitlayer Bridge enables users to move BTC from the main Bitcoin chain into Bitlayer’s scalable environment—a process known as "crossing in." This tutorial focuses on BTC cross-chain deposits (cross-in) using compatible wallets like OKX Wallet.

Prerequisites: What You Need Before Bridging

Before initiating a cross-chain transfer, ensure you have the following:

  1. Bitcoin (BTC) in your wallet – Required for bridging and paying network fees.
  2. A BTC-compatible wallet such as Unisat Wallet, OKX Wallet, or Bitget Wallet.
  3. An EVM-compatible wallet (e.g., MetaMask, OKX Wallet, Bitget Wallet, Tokenpocket) to interact with Bitlayer’s smart contracts.
  4. Internet access and familiarity with wallet extensions.
✅ Note: OKX Wallet supports both BTC and EVM chains, making it a convenient all-in-one solution.

If you don’t yet have OKX Wallet installed, follow standard wallet creation procedures within the browser extension or mobile app. Always download wallets from official sources to avoid phishing risks.

Step-by-Step Guide: Bridging BTC to Bitlayer via OKX Wallet

Follow these clear steps to securely transfer your BTC from the Bitcoin mainnet to Bitlayer.

Step 1: Access the Official Bitlayer Bridge

Navigate to the official website:
👉 https://bitlayer.org

Click on [Bridge & Earn] in the navigation menu. This section hosts the cross-chain functionality and potential yield opportunities.

🔒 Security Tip: Always verify the domain is bitlayer.org. Avoid entering through third-party links or search ads to prevent scams.

Step 2: Connect Your BTC Wallet

Click [Connect Wallet] and select your BTC wallet. In this example, choose [OKX Wallet] from the list.

After selection, confirm the connection in your wallet extension. Once linked, your wallet address will appear on the screen.

Step 3: Enter the Amount of BTC to Bridge

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

Ensure your total BTC balance meets this formula:
(Balance) – (Transfer Amount) ≥ 0.00015 BTC

Failure to meet this condition will result in an error during processing.

Step 4: Connect Your EVM-Compatible Wallet

Since Bitlayer runs on an EVM-compatible chain, you must also connect an EVM wallet to receive assets on the L2 side.

Click [Connect Wallet] again and choose one of the supported options:

For consistency, we recommend using OKX Wallet if already set up—it simplifies asset management across chains.

Confirm the connection when prompted in your wallet interface.

Step 5: Initiate the Transfer

Once both wallets are connected, click [Transfer].

Your OKX Wallet extension will pop up with a transaction request. Review the details carefully, including:

Click [Confirm] to sign and broadcast the transaction.

Step 6: Monitor Transaction Status

Frequently Asked Questions (FAQ)

Q: Does Bitlayer support tokens other than BTC?
A: Currently, the official Bitlayer bridge only supports BTC cross-chain deposits. Support for additional assets may be added in future updates.

Q: Why do I need two wallets (BTC + EVM)?
A: Bitlayer uses BTC for security and settlement but operates smart contracts via EVM compatibility. You need a BTC wallet to send funds and an EVM wallet to receive and use them on Layer 2.

Q: How long does the cross-chain process take?
A: Typically between 10–30 minutes, depending on Bitcoin network congestion. Delays can occur during peak usage periods.

Q: Can I reverse a transfer after confirmation?
A: No. Blockchain transactions are irreversible. Always double-check amounts and addresses before confirming.

Q: Is there a withdrawal (cross-out) function?
A: Yes, users can bridge BTC back from Bitlayer to Bitcoin mainnet via the same bridge interface under Withdraw or Cross-Out options.

Q: What should I do if my transaction is stuck?
A: Wait at least one hour before taking action. If still pending, check the transaction hash on a blockchain explorer or contact Bitlayer’s official support channels.
