xBTC is a wrapped token issued by OKX, backed 1:1 with native Bitcoin reserves. This secure and transparent solution allows users to seamlessly bring their BTC into the decentralized finance (DeFi) ecosystem without sacrificing safety. By converting your Bitcoin into xBTC, you unlock a new world of blockchain-based financial opportunities across multiple high-performance networks.
What Is xBTC?
xBTC is a fully reserved, 1:1 Bitcoin-pegged wrapped token managed by OKX. Each xBTC in circulation is fully backed by real BTC held in reserve, ensuring asset integrity and trustless usability. Unlike traditional custodial models, xBTC leverages on-chain Proof of Reserves (PoR), allowing users to independently verify the backing assets at any time.
This transparency ensures that every xBTC reflects actual Bitcoin ownership — making it both secure and reliable for use across various DeFi platforms.

Key Advantages of xBTC
1. Full Reserve Transparency
With real-time on-chain Proof of Reserves, users can verify that the total supply of xBTC matches the BTC held in custody. This level of openness builds trust and strengthens confidence in the token’s long-term reliability.
2. Seamless Cross-Chain Interoperability
xBTC enables Bitcoin holders to move value across blockchains efficiently. Powered by OKX's secure deposit and withdrawal infrastructure, xBTC supports fast, low-cost transfers between chains while maintaining the security of native Bitcoin.
3. Native Integration with DeFi Ecosystems
Unlike standard BTC, which often remains idle in wallets, xBTC can be actively used in lending, borrowing, liquidity provision, and yield generation across multiple DeFi protocols — maximizing capital efficiency without compromising asset safety.
How to Use xBTC
Using xBTC is simple and intuitive:
- When you withdraw BTC from your OKX account to a supported blockchain (such as Solana, Sui, or Aptos), you automatically receive an equivalent amount of xBTC on that chain.
- Conversely, when you deposit xBTC back into your OKX account from a supported network, it is automatically converted into native BTC.
This seamless conversion process allows for frictionless movement between centralized custody and decentralized applications.
There are no additional fees beyond the standard withdrawal fee when converting BTC to xBTC — no hidden costs, no complexity.
xBTC in the DeFi Landscape
xBTC is designed to bridge Bitcoin’s value with next-generation DeFi ecosystems. It will initially launch on Solana, Sui, and Aptos, with plans to expand to more chains in the future.
Here are some leading DeFi platforms where xBTC can be utilized:
Navi – Sui’s All-in-One Liquidity Protocol
Navi offers native lending and borrowing services within the Sui ecosystem. Users can supply xBTC as collateral or earn interest by lending it out — all with near-instant transaction finality and minimal fees.
Hyperion – High-Performance DEX on Aptos
Built specifically for Aptos, Hyperion combines an orderbook model with AMM mechanics to deliver fast, efficient trading. Traders can use xBTC for spot trades or as margin collateral, benefiting from Aptos’ high throughput and low latency.
Aries Markets – Full-Service DeFi Platform
Aries provides a comprehensive suite of financial tools including money markets, leveraged positions, and cross-asset lending. Integrating xBTC allows users to access advanced strategies typically unavailable to pure Bitcoin holders.
Kamino – Automated Liquidity Vaults
Kamino simplifies yield farming by offering auto-compounding liquidity pools based on Concentrated Liquidity Market Makers (CLMM). By depositing xBTC into these vaults, users optimize returns while reducing manual management.
Momentum – Next-Gen DEX in the Move Ecosystem
Momentum empowers traders, liquidity providers, and protocols through innovative incentive structures and capital-efficient designs. With xBTC integration, participants gain enhanced control over trading outcomes and improved fee earnings.
Orca – Leading DEX on Solana
As one of Solana’s most trusted decentralized exchanges, Orca enables fast and affordable swaps. xBTC can be paired with other tokens for trading or added to liquidity pools to generate passive income.

Security and Transparency: Built Into Every Transaction
We uphold the highest standards of security and accountability. Every xBTC token is backed 1:1 by real Bitcoin reserves stored in cold wallets under OKX’s institutional-grade custody.
All critical data — including total reserves and circulating supply — is publicly verifiable on-chain:
- Total Reserves: 1,078.744 BTC ($114,578,692.75)
- Total Supply: 1,078.645 xBTC ($114,568,200.71)
The slight variance between reserve and supply amounts falls within normal operational tolerance due to pending settlements and network confirmations.
Independent auditing firms Certik and MoveBit have completed comprehensive smart contract audits for xBTC as of May 19, 2025, confirming its robustness against vulnerabilities and exploits.
