Wrapped Bitcoin's price today is $108,455.95, with a 24-hour trading volume of $230.83 million. WBTC has a circulating supply of 163,106 tokens and a maximum supply of 163,106 WBTC.
What Is Wrapped Bitcoin?
Wrapped Bitcoin (WBTC) is an ERC-20 token on the Ethereum blockchain that is backed 1:1 by Bitcoin. It brings Bitcoin’s deep liquidity into the Ethereum ecosystem, allowing users to participate in decentralized exchanges (DEXs) and a wide range of financial applications. By standardizing Bitcoin into the ERC-20 format, WBTC enables smart contract functionality for Bitcoin, bridging two major blockchain networks.
A Brief History of Wrapped Bitcoin
Wrapped Bitcoin was introduced in January 2019 as a collaborative initiative between BitGo, Kyber Network, and Ren. BitGo acts as the custodian, holding the underlying Bitcoin reserves. Meanwhile, Kyber Network and Ren function as merchants within the WBTC network, assisting with the minting and burning processes that ensure the 1:1 peg between WBTC and Bitcoin.
How Does Wrapped Bitcoin Work?
WBTC is created by locking Bitcoin with a centralized custodian, BitGo, which then mints an equivalent amount of WBTC on the Ethereum blockchain. This mechanism allows Bitcoin holders to access Ethereum’s decentralized finance (DeFi) ecosystem without selling their BTC. Ethereum’s faster transaction speed and smart contract capabilities enable more efficient trading, lending, and borrowing compared to the native Bitcoin network.
Because WBTC follows the ERC-20 standard, it is compatible with a wide variety of wallets, decentralized applications (dApps), and financial protocols. This cross-chain compatibility makes it a popular tool for users seeking both the store of value offered by Bitcoin and the utility of the Ethereum network.

What Is Wrapped Bitcoin Used For?
The primary use of Wrapped Bitcoin is to provide Bitcoin holders access to decentralized financial services such as:
- Lending and borrowing through DeFi platforms
- Trading on decentralized exchanges (DEXs)
- Earning yield via liquidity pools and yield farming
Since Bitcoin itself cannot natively interact with most DeFi applications on Ethereum, converting BTC to WBTC unlocks these opportunities. This allows users to retain Bitcoin-based value while engaging with faster, more versatile Ethereum-based services.
Advantages of Using WBTC
- Interoperability: Bridges the Bitcoin and Ethereum ecosystems.
- Liquidity Access: Unlocks DeFi opportunities for Bitcoin holders.
- Speed and Efficiency: Leverages Ethereum’s faster transaction capabilities.
Risks and Considerations
While WBTC offers significant utility, users should be aware of certain risks:
- Custodial Risk: Relies on trusted custodians to hold the underlying Bitcoin.
- Smart Contract Vulnerabilities: As with any Ethereum-based token, WBTC is subject to potential smart contract bugs or exploits.
- Regulatory Uncertainty: The regulatory landscape for wrapped assets continues to evolve.
It’s essential to use reputable platforms and perform due diligence before minting, burning, or trading WBTC.

Frequently Asked Questions
What is the difference between BTC and WBTC?
BTC is the native cryptocurrency of the Bitcoin blockchain, while WBTC is an Ethereum-based token backed 1:1 by BTC. WBTC enables Bitcoin holders to use their assets in the Ethereum DeFi ecosystem.
How is WBTC pegged to Bitcoin?
WBTC maintains a 1:1 peg through a mint-and-burn process managed by merchants and custodians. For every WBTC minted, one BTC is held in reserve, and burning WBTC releases the corresponding BTC.
Is Wrapped Bitcoin safe?
WBTC is generally considered safe but involves trust in centralized custodians. Users should verify that the custodian is reputable and that the smart contracts have been audited.
Can I convert WBTC back to Bitcoin?
Yes, WBTC can be converted back to Bitcoin through authorized merchants by burning the WBTC tokens, which releases the underlying BTC from custody.
Which wallets support WBTC?
Most Ethereum-compatible wallets that support ERC-20 tokens can store WBTC. Popular options include MetaMask, Trust Wallet, and Ledger hardware wallets.
Where can I buy Wrapped Bitcoin?
WBTC is available on numerous cryptocurrency exchanges and decentralized platforms. Always ensure you are using a trusted exchange with sufficient liquidity.
