Bridging Bitcoin (BTC) to emerging Layer 2 networks is a powerful way to unlock new utility for your digital assets. Bitlayer, as a Bitcoin Layer 2 (L2) solution compatible with the Ethereum Virtual Machine (EVM), enables users to leverage BTC in decentralized applications while benefiting from fast, low-cost transactions. This comprehensive guide walks you through the step-by-step process of using the official Bitlayer cross-chain bridge to move BTC from a Bitcoin wallet to the Bitlayer network — with a focus on using the OKX Wallet.
Whether you're new to Layer 2 ecosystems or an experienced DeFi explorer, this tutorial ensures a smooth onboarding experience into the Bitlayer ecosystem.
Understanding Bitlayer and Its Cross-Chain Functionality
Bitlayer is a Bitcoin-centric Layer 2 blockchain designed to scale BTC’s capabilities by enabling smart contracts and EVM compatibility. As a result, users can deploy and interact with dApps, participate in yield-generating protocols, and explore decentralized finance — all powered by BTC.
The Bitlayer cross-chain bridge allows BTC holders to securely transfer their assets from the Bitcoin mainnet to the Bitlayer network. This process, known as "bridging," is essential for activating your BTC within Bitlayer’s growing ecosystem.
Currently, the bridge only supports BTC as the bridged asset, though future updates are expected to include additional tokens. Only select BTC-compatible wallets are supported, including OKX Wallet, Unisat Wallet, and Bitget Wallet.
To complete the cross-chain transfer, you’ll need two wallets:
- A Bitcoin wallet (e.g., OKX Wallet) to hold and send BTC
- An EVM-compatible wallet (e.g., MetaMask, OKX Wallet, Bitget Wallet, Tokenpocket, or any WalletConnect-enabled app) to interact with Bitlayer’s smart contracts

Step-by-Step Guide: Bridging BTC to Bitlayer via OKX Wallet
Follow these clear steps to successfully bridge your BTC to the Bitlayer network.
Step 1: Access the Official Bitlayer Bridge
Open your browser and navigate to the official Bitlayer website: bitlayer.org. Always verify the URL to avoid phishing sites. Once loaded, click on Bridge & Earn to enter the cross-chain interface.
🔒 Security Tip: Only use the official domain — bitlayer.org — to prevent falling victim to scams or fraudulent bridges.
Step 2: Connect Your Bitcoin Wallet
Click Connect Wallet and select OKX Wallet from the list. If your wallet extension is installed and active, it will prompt you to approve the connection. Confirm the request in your OKX Wallet popup.
Once connected, your BTC address will be displayed, showing your current BTC balance.
Step 3: Enter the Amount to Bridge
Input the amount of BTC you wish to transfer to Bitlayer. Keep in mind two critical requirements:
- Minimum transfer amount: 0.0005 BTC
- Cross-chain fee: 0.00015 BTC (deducted separately)
Ensure your total balance covers both the transfer amount and the fee. For example, if you want to bridge 0.0005 BTC, your wallet must hold at least 0.00065 BTC.
Step 4: Connect Your EVM-Compatible Wallet
After entering the amount, click Connect Wallet again — this time to link an EVM-compatible wallet such as MetaMask, OKX Wallet, Bitget Wallet, or any WalletConnect-supported application.
If you're using OKX Wallet for both BTC and EVM functions, simply select it again and approve the connection. The interface will confirm both wallets are linked.
👉 Seamlessly manage both BTC and EVM chains in one secure wallet — start bridging now.
Step 5: Confirm and Initiate the Transfer
With both wallets connected and the amount set, click Transfer. Your OKX Wallet will prompt you to sign the transaction. Review the details carefully, then click Sign to authorize.
Once signed, the transaction enters a pending state. You’ll see a transaction record labeled Pending on the bridge interface.
Step 6: Wait for Completion
Processing time varies depending on network congestion. Typically, transfers complete within minutes. When successful, the status will change to Completed, and you’ll see your Bitlayer-bound BTC address indicated by an arrow or link.
Congratulations — your BTC has now been bridged to the Bitlayer network!
