xBTC is a wrapped form of Bitcoin (BTC), pegged 1:1 with the value of native BTC and backed securely by OKX. Designed to bring Bitcoin’s value onto alternative blockchains, xBTC enables seamless integration of BTC into decentralized finance (DeFi) ecosystems across multiple networks. This means you can use your Bitcoin in DeFi protocols, decentralized exchanges, and blockchain-based applications—without giving up the underlying value of your BTC.
Currently, xBTC is supported on high-performance blockchains including Solana, Sui, and Aptos. When you withdraw BTC from your OKX account to one of these networks, it is automatically converted into xBTC and sent to your designated wallet address on that chain. This conversion allows you to leverage Bitcoin within fast, low-cost environments where traditional BTC cannot natively operate.
Conversely, when you send xBTC back to your OKX account from any supported network, the system recognizes the incoming token and instantly converts it back into standard BTC. This process ensures a smooth, user-friendly experience for moving Bitcoin across ecosystems while maintaining its full value.
Understanding xBTC: Key Features and Benefits
xBTC preserves the purchasing power and market value of Bitcoin while enhancing its utility. Unlike regular BTC, which operates only on the Bitcoin blockchain, xBTC functions natively on modern, scalable networks. This opens up several advantages:
- Faster transactions: Experience near-instant transfers compared to Bitcoin’s 10-minute block time.
- Lower fees: Benefit from significantly reduced transaction costs on Solana, Sui, and Aptos.
- DeFi compatibility: Use xBTC as collateral, provide liquidity, or trade across decentralized platforms.
- 1:1 backing: Every xBTC in circulation is fully backed by real BTC held in reserve.
This makes xBTC an ideal solution for users who want to maximize the potential of their Bitcoin holdings beyond simple holding or trading.

How to Deposit xBTC to Your OKX Account
Depositing xBTC is a straightforward process that converts your wrapped Bitcoin back into standard BTC within your OKX account. Here's how to do it step by step:
Step-by-Step Guide
- Access the Deposit Section
Log in to your OKX account and navigate to the Deposit section. Click on Deposit crypto to get started. - Select Bitcoin (BTC)
Choose Bitcoin (BTC) as the asset you're depositing—even though you're sending xBTC, OKX will recognize it as equivalent BTC upon receipt. - Choose the Source Network
Select the blockchain network (e.g., Solana, Sui, or Aptos) from which you’ll be transferring your xBTC. - Copy Your Deposit Address
OKX will generate a unique deposit address specific to that network. Carefully copy this address—do not make any manual changes. - Send xBTC from Your External Wallet
Open your external wallet (such as Phantom for Solana or Sui Wallet), initiate a transfer, and paste the copied address. Confirm the transaction. - Wait for Confirmation
Once the network confirms the transaction, OKX will automatically convert your xBTC into BTC and credit the amount to your account balance.
Note: Always double-check the network and address before sending. Transactions on blockchain are irreversible.
After completion, you’ll see the updated BTC balance in your OKX wallet—ready for trading, staking, or further withdrawals.
How to Withdraw xBTC from OKX
Withdrawing BTC from OKX as xBTC allows you to take your Bitcoin off-exchange and use it in external DeFi applications. Follow these steps to complete the process securely:
Step-by-Step Guide
- Go to Withdraw Section
From your OKX dashboard, click on Withdraw, then select Withdraw crypto. - Choose Bitcoin (BTC)
Even though you’ll receive xBTC, select Bitcoin (BTC) as the withdrawal asset. - Select Destination Type
Choose Exchange or wallets if you’re sending to a personal wallet or DeFi platform. - Pick the Target Network
Select one of the supported chains: Solana, Sui, or Aptos, depending on where you plan to use the xBTC. - Enter Recipient Address
Input the wallet address where you’d like to receive the xBTC. Ensure this address supports the selected network and token type. - Specify Withdrawal Amount
Choose the account (e.g., Funding or Trading) and enter the amount of BTC you wish to withdraw. - Review Fees and Final Amount
The system will display the network fee and the net amount of xBTC you’ll receive. Verify all details carefully. - Confirm and Submit
Click Withdraw to finalize the request. OKX will convert your BTC into xBTC and send it to your specified address on the chosen blockchain.
The entire process typically completes within minutes, depending on network congestion.
