Wrapped Bitcoin, commonly known as WBTC, is a leading tokenized version of Bitcoin that operates on the Ethereum blockchain. It enables Bitcoin holders to participate in the decentralized finance (DeFi) ecosystem while maintaining exposure to Bitcoin’s value. As of the latest data, WBTC is priced at approximately $107,439.79, closely mirroring the value of Bitcoin itself.
Understanding Wrapped Bitcoin (WBTC)
Wrapped Bitcoin is an ERC-20 token backed 1:1 by Bitcoin, meaning each WBTC token represents one Bitcoin held in reserve by a custodian. This design allows Bitcoin to be used within the Ethereum network, leveraging its smart contract capabilities and extensive DeFi applications.
How WBTC Works
WBTC operates through a collaborative process involving custodians, merchants, and users. Here’s a simplified breakdown:
- Minting: Users send Bitcoin to a certified custodian, who then mints an equivalent amount of WBTC on the Ethereum blockchain.
- Usage: The newly minted WBTC can be used across various Ethereum-based DeFi protocols for lending, borrowing, trading, or providing liquidity.
- Redeeming: When users wish to convert WBTC back to Bitcoin, they burn the WBTC tokens, and the custodian releases the underlying Bitcoin.
This process ensures transparency and trust, as all minted WBTC is fully collateralized by Bitcoin reserves.
Key Technological Features
WBTC complies with the ERC-20 standard, making it compatible with most Ethereum-based applications. Its integration into DeFi platforms allows users to access advanced financial services without selling their Bitcoin holdings. The protocol is governed by the WBTC DAO (Decentralized Autonomous Organization), which oversees upgrades and changes to the system.
Use Cases for WBTC
WBTC unlocks numerous opportunities within the DeFi landscape:
- Lending and Borrowing: Platforms like Aave, Compound, and MakerDAO allow users to use WBTC as collateral for loans.
- Liquidity Provision: Users can supply WBTC to liquidity pools on decentralized exchanges (DEXs) like Uniswap or Balancer to earn fees.
- Margin Trading: WBTC facilitates margin trading on supported platforms, enhancing capital efficiency.
- Corporate Treasury Management: Businesses can tokenize Bitcoin holdings into WBTC for easier integration into DeFi strategies.

Founding Organizations Behind WBTC
WBTC was launched through a collaboration between three prominent organizations:
- BitGo: A digital asset custody and financial services provider responsible for holding the Bitcoin reserves.
- Kyber Network: A decentralized liquidity protocol that enables seamless token swaps and integrations.
- Ren: A project focused on cross-blockchain interoperability, facilitating asset movement between networks.
These entities ensure the security, reliability, and decentralization of the WBTC ecosystem.
Advantages of WBTC
WBTC combines Bitcoin’s liquidity with Ethereum’s programmability:
- Liquidity Access: WBTC brings Bitcoin’s vast liquidity into the DeFi space, enabling larger transactions and better pricing.
- Speed: Transactions with WBTC settle in approximately 15 seconds on Ethereum, compared to Bitcoin’s 10-minute block time.
- Interoperability: Exchanges, wallets, and payment services can support WBTC with minimal infrastructure, requiring only an Ethereum node.
- Security: WBTC inherits security from both Bitcoin’s blockchain and Ethereum’s robust smart contract environment.
WBTC Supply and Circulation
WBTC does not have a fixed issuance schedule. The circulating supply depends entirely on user demand, as tokens are minted or burned based on Bitcoin deposits and withdrawals. This ensures that WBTC remains fully backed at all times.
As of now, over $10.9 billion worth of WBTC is circulating in the market, reflecting significant adoption among institutions, DeFi users, and corporate treasuries.
